Wooden boxes for nuts-and-bolts

One of my skill-sets is "Throughput Improvement". One of the quick-tools I used when improving through-put was to look for where in-process inventory was stacked up. You knew you were getting close to a bottleneck when you had a buffer (or bank) that was always full. There had to be a choke-point somewhere downstream of that traffic pile-up.

One reason I am pretty focused on making sturdy storage boxes is because we have dozens-and-dozens of lids for plastic tubs...and very few tubs to put them on. That tells me that the tubs are the weak-link.

Let me introduce the ERJ Mark 2-S storage box.

This is my second try. "S" stands for short. There will be a "T" version in the future.

Interior dimensions are 15.5" long, 9.0" wide and 5.5" tall. The "T" version will have an interior height of 11". Distance center-line of handle to center-line of handle is 21.5"


The 10.5" exterior width was chosen because the stringers on a standard pallet are 3.5" wide and 3 X 3.5" = 10.5". It is pretty easy to cut 17" long pieces from a 40" by 48" pallet.

e
The bottoms of the handles are 1.5" above the resting surface....

...and 1.5" from the end panel of the box. Radii are routered into the two-by-twos to be finger-friendly. I wanted enough room to be able to pick them up while wearing winter gloves.  The "T" version will have the same handle location because I dislike bumping into sharp corners with my thighs when carrying boxes.

My long-term plan is to add some "skiis" to the bottom to keep them from bowing and to add a top with hinges and hasp.

The corner reinforcements are 2-by-2s and project 0.65" above the top-and-bottoms of the 1-by-6 sides. The intention is to protect the top and bottom panels (pallet stringers) from corner impacts.

I used pole-barn siding screws because somebody (Kubota) borrowed my impact driver and T25 bits and hadn't brought them back. The siding screws does make the box more photogenic in the sense that you can see how it goes together.

Commodity 2X2s are about $0.30 a foot. #2 1"X6" are about $1.20 a foot. The box uses just shy of 5' of 1X6s and just shy of 4' of 2x2s. That pencils out to a skoosh over $7.20 in lumber costs for the "S" version boxes. 

Minor improvements include using 1/4 X 1-1/4" long crown staples to position the bottom slats with short screws at ends for structural integrity. That should really speed up the process...as will having my impact driver.

From a volume standpoint, the "S" version has a bit more than three gallons of capacity and the "T" version will have an internal volume of about 6.5 gallons.

The box without a cover weighs 9 pounds and most adults should be able to carry 40 pounds (gross) given the better-than-average ergonomics.

Quicksilver is potty-training herself

Quicksilver is 2-1/4 years old and she decided that she wanted to wear "big girl" pants. Of course, that means that she needs to use the potty.

In the course of a week, she went from sitting on her training-toilet for a grand sum of five seconds to leaving a healthy puddle in it about half the time. She gets one M&M for sitting on the potty-chair for 20 seconds (and hissing an "ssss" sound...helps her relax) and TWO M&Ms for actually leaving some physical evidence in the bowl.

Every kid is different. I was stunned to learn that more-and-more parents are sending their kid to Kindergarten in diapers because the child is NOT toilet trained. Maybe it is just a blip. Those are the kids who were in the golden-window, age-wise, during Covid shutdowns.

I am not fond of Disney and dislike purchasing products that feature their characters. But considering the application, it seems appropriate that they should be on garments designed to catch excrement.

On a related note:

Vitamin B6 appears to reduce the likelihood of kidney stones.

Source

3/4 of all kidney stones are calcium oxalate. Unfortunately, calcium oxalate stones are not smooth. Nope, far from it.

Vitamin B6 appears to simultaneously reduce the amount of oxalate produced in the body AND increase the citric acid content of the urine. The citric acid is a chelating agent binds to the calcium ions and keeps the calcium from binding to the oxalate.

Source

If you know you are at risk of developing kidney stones (family history, for instance), you still need to stay well hydrated and to avoid foods like spinach, rhubarb, Swiss chard and other foods that are naturally rich in oxalates.

What does the Bible say about being prepared?

Jesus told his disciples this parable:
"The Kingdom of heaven will be like ten virgins
who took their lamps and went out to meet the bridegroom.
Five of them were foolish and five were wise.
The foolish ones, when taking their lamps,
brought no oil with them,
but the wise brought flasks of oil with their lamps.
Since the bridegroom was long delayed,
they all became drowsy and fell asleep.
At midnight, there was a cry,
'Behold, the bridegroom! Come out to meet him!'
Then all those virgins got up and trimmed their lamps.
The foolish ones said to the wise,
'Give us some of your oil,
for our lamps are going out.'
But the wise ones replied,
'No, for there may not be enough for us and you.
Go instead to the merchants and buy some for yourselves.'
While they went off to buy it,
the bridegroom came
and those who were ready went into the wedding feast with him.
Then the door was locked.   -Matthew Chapter 25

One of the lines I keep hearing from Progressives, many who claim to be Christians, is "What are you afraid of?" That is their kill-shot to shut down argument. From a Nanny-state perspective, it has a certain logic. To question is to threaten the house-of-cards of mutual collusion.

I will own my fear. I am afraid of failing my Christian Duty to protect those that God entrusted me to be the steward-and-protector of.

The New Testament describes those who are prepared as "...wise..." and those who trusted in God's providence and other's generosity as "...foolish...".

"Fear" is not a bad thing. God gave it to us for a reason. It helps us be wise.

To assume that "fear" is always a bad thing is to say that God made a mistake. You can either be a Biblical Christian or you can be sheep. Choose.

God did not build the ark for Noah. Nor did the State.

And just for fun...

There is a lot to be said for team-work and playing ball with the folks you have been practicing with for most of your life.

Friday Odds-and-Ends

Pond Creek, Oklahoma

For some reason, Pond Creek, Oklahoma popped into my head. It is just east of the "dry-line" that extends roughly from Austin, USSR to Brandon, Manitoba.

Pond Creek is thirty miles east of where the Medicine Lodge river joins the Salt Fork Arkansas river and and 14 miles west of where Pond Creek merges with the SFA river. I am just guessing here, but I suspect there is pretty good cat fish in those rivers.

Housing is inexpensive running from $75/sq-ft to $150/sq-ft. Property is not cheap if you consider the rainfall and potential for a string of drought years. But it is also not hugely expensive, either.

Summers are hot with daily highs average in the mid-90s (F) in July and August. Tornadoes happen. 

Winters are mild with daily average highs of  50 in Dec, Jan and Feb with lows in the mid-to-upper 20s. Averages are deceiving; blizzards come suddenly and have brutal wind-chills. No big cities are nearby (Wichita is 90 miles by road). Ground water is abundant and population densities in Grant County, Oklahoma of about 4 per square-mile.

Honorable mention to Ponca City, Oklahoma and Kay County. It is a little larger and a little more accessible than Pond Creek. It is on the main branch of the Arkansas river and offers serious catfishing opportunities below the Kaw dam. Kaw dam pond is about 26 square-miles in surface area. Population density (humans) is about 40 per square mile for the county.

Bee-swarms

Sprite gave Mrs ERJ a call. She has "issues" with bee stings. She was not able to enter her garage because of a sudden explosion in the population of stinging insects.

Based on history, she assumed they were yellow-jackets.

Mrs ERJ was in Charlotte. She called me. I went over to check out the situation and to move Sprite's truck out of the garage so she could make her appointments.

It was a swarm of honey bees.

In general, swarms of honey bees are not very aggressive. They have no "brood" or honey comb to protect. But Sprite cannot afford to take any chances.

I moved her truck out of her garage and we debated the plusses and minuses of her closing the garage door.

Bees that swarm this time of year at this latitude have zero chance of surviving the winter. There is not enough time for them to make comb and store enough honey and pollen, even though the goldenrod bloom is very productive.

Somewhere nearby, there is a hive that is running out of room and it split. If a fella could figure out where that was, it would be worth his time to put a few "trap hives" out next spring, even if they were simple top-bar affairs with no bottoms.

Grafting "found" seedlings

My friend Lucky sent me an email with a picture of a pear seedling that was growing in a fence-row.

I share Lucky's gift from him-to-me, a picture of a "Bradford" seedling that he grafted this spring:

The fork is somewhere between belt-buckle height and four feet above the ground and the stem is 1.5" in diameter. The graft pushed an easy 10 feet of growth in one summer. 

Power wires. Red leaved "bushes" are Pyrus calleryana seedlings, aka "Bradford" pears. South side of M-43 just east of I-96  in Eaton County, Michigan. Google Street view.

Fence-rows and beneath power-lines are great places to find seedlings that can be grafted. Contrary to popular belief, "Bradford" flowering pear and crabapple seedlings make fine root-stocks. Birds eat the berries and plant the seeds with a dollop of fertilizer when they take-flight from power lines or the top wire of a fence.

I actually walked this ground and scouted for P. calleryana seedlings that could tolerate "wet feet". I was not successful. Hundreds of seedlings. Only one was growing in the bottom of a ditch and I chose to not collect bud-wood from that specimen.

It is unfortunate that the sites that are best for growing fruit are also most desirable for up-scale building sites. Fruit-growers find themselves priced out of the market and forced to grow trees on sites that are less-than-optimal.

Given the fact that P. calleryana (and hybrids) fruit can be swept up off the pavement by the cubic-yard and the economical Phytophthora screening protocols developed by Herb S. Aldwinckle at Cornell, it wouldn't be hard to identify gifted specimens with resistance to diseases common to wet soils.

A girl has to stay safe

I had Quicksilver practice blowing a whistle. Photos were taken and shared with her mother.

I promised to send QS home with her new toy safety tool.

For some reason, parents are sometimes slow to develop their children's musical talents. I guess that means it is up to the grandparents.

Go-Pros and Transparency

One of the best suggestions I heard in a long while came from a fellow gardener who lives in Indiana.

He suggested that all candidates who engage in televised debates must wear a Go-Pro (a head-mounted video camera so we see what he/she sees) and that the Go-Pro footage be play in simultaneously as a box-within-a-box. 

An alternative would be to play both candidates' teleprompter feeds as box-within-a-box displays through the course of the debate.

That way, voters can figure out how much of what is coming out of the candidate's mouth is coming from their brain and how much is coming from the invisible (un-elected and anonymous) "handlers".

To make this work, audio devices for communicating with the candidates must be banned.

The candidate that has command of the facts and whose brain is agile will have little information coming across the teleprompter. The candidate who needs to be reminded to inhale-and-exhale and is fed lines word-for-word will be outed.

Thanks Milton!

Dr. Leaky I presume...

 

"Oh Joe! Oh Joe my sweetheart!" I heard the honeyed tones of my beautiful wife's voice call out in the night.

"Yes my love-bug?" I responded.

"There seems to be some water on the bathroom floor" Mrs ERJ observed.

"A little or a lot?" I asked. It could be condensate after all.

"Hmmm, hard to say. I am on my third bath-towel mopping it up" she supplied me with more detail.

"Yep, that's a lot" I told her.

 The valve on the end of the nipple sprung a leak. I THINK it is fixed. The only hiccup was that I bought a 1/2NIR-3/8" compression fitting valve and the nipple was 3/8".

Any day I can fix a leak with only two trips to the hardware store is a good day.

Pears for the south-shore of Lake Superior

Frequent commenter Coyote Ken asked if I had any recommendations for pears to plant. Ken lives a few miles of Lake Superior's southern coast.

The challenge is two-fold:

  • Winter coldhardiness
  • Lack of heat during the growing season to ripen the fruit.

Bartlett is the standard by which all other varieties are compared. In fact, if any of Ken's neighbors had ever planted a pear tree, it would have almost certainly been a Bartlett. Since none of his neighbors are growing pears, it seems probable that Bartlett was tried and found wanting.

Growing Degree Days

Growing Degree Days (GDDs) is a way of comparing different regions and of comparing historical data to the current year. The most common way of calculating GDDs is to average the daily high temperature, in Fahrenheit, and daily low temperature. If the average is above 50F, then to subtract 50F from that number and add to the tally.

So, if Bartlett pears ripen around August 22 in Eaton County most summers then there is historical data that suggests that in Michigan Bartlett pears need approximately 2200 GDDb50.

Jumping up to Chatham, Michigan which is somewhere near where Coyote Ken lives, we see that the 20 year average for October 10 is 1900 GDDb50. That suggests that inadequate heat to ripen Bartlett will be a real problem.

But that isn't the only way to use GDDs

If we know that we will only have 1900 GDDs in Chatham most years, then we can walk back in time using Eaton County data and find out what day that is likely to be. That date is August 7 or approximately two weeks before Bartlett ripens. That gives us the information to start looking through lists of pears that have a snowball's chance near Lake Superior.

10 days before Bartlett: 

 Harrow Gold

 Clapp's Favorite (large fruit)

 Ubileen

 Coscia

 Summercrisp (I am cheating here, but it is said to be tasty before fully ripe)


14 days before Bartlett: 

Harrow Delight (tends to drop before ripe)

 

20 or more days before Bartlett: 

 Butirra Precoce Morettini

 Bella Di Guigno

 Beurré Giffard

 Golden Spice (very cold-hardy)

In general, the price of earlier ripening is smaller fruit. Nearly all pears require a second variety for pollination reasons. The varieties with "Harrow" in their names are resistant to fire blight.

Fedco, Raintree, One Green World, Burnt Ridge and Cummins nurseries are good places to look for some of these odd-ball varieties.

I know that some of my readers are rock-stars at growing food. Please feel free to add your opinions in the comments. That includes poor recommendations on my part. I tried to leave off pears that had mediocre flavor or were rumored to take a long time to come into bearing.

 

Last Minute Prepping for Apartment Dwellers

I was able to get out to the property yesterday.

I dropped of a set of metric and SAE box-end wrenches, reset the traps and threw some more seeds around the food-plot.

God loves me. Lower Michigan picked up about a 1/2" of rain five hours after I broadcast the rape (kale) and radish seeds. It would have been better if I had planted a month ago, but I had not killed off the brush that was shading the ground at that point.

Lists of Essential Equipment

As I was hanging the wrench-sets on the wall of the pole barn, it got me thinking about the lists of The Top Fifty (or Seventy or One Hundred) Items to Buy Now!!! that are popping up on the Internet.

I thought of the family living in an 800 square-foot apartment and could not imagine where they would put most of the gear on those lists.

I suggest using the Rule of Threes to prioritize:

  • Three seconds of stupid can kill you
  • Three minutes without oxygen getting to your brain (suffocation, loss of blood)
  • Three hours of exposure can kill you.
  • Three days without water
  • Three weeks without food

Example:

I was lowering eggs into boiling water using a metal spoon. I was using the hot-plate on the porch to keep the heat and humidity outside. I felt a tingle when the spoon touched the water. Then it happened again.

I got my multi-tester electrical tool. Yup, the hot-plate had a short-to-hot in the wiring. Its rubber coasters prevented it from shorting to the table and thence to the concrete floor.

The hot-plate went into the trash.

Another example: 

It gets cold in Michigan in the winter. Not Minnesota or Alberta cold, but cold enough to kill you. Most apartments have enough storage to squirrel away enough quilt/comforters/sleeping bags to throw on the beds to make 20F inside temperature endurable.

The point being, even if you have a storage unit, there are some camping items that are worth storing in your apartment.

Another:

Having some non-electrical means to cook food or boil water doesn't have to consume a lot of space. There are countless one-burner, propane fired camp stoves/hot-plates that are available.

Finally:

Sometimes the "stupid" is going outside of your apartment outside of very specific time-slots. Having various comfort items, especially if you have kids, is a no-brainer. One example would be to have some zero-sugar lollipops handy. With a little bit of care, a lollipop can last a while and keep the sniffles and whining down. Another spin on this is to have the means to have at least 24 hours of water stored so you aren't forced to go looking for it at a dangerous time of night.

These examples are not comprehensive. They are just a few vignettes to show one way of deciding what you can do to harden your apartment should power-outages or civil unrest come to your neighborhood.

Quality is in the eye of the beholder

 

One of my nephews purchased a new home and he is exploring the grounds.

He has a pear on the property and asked if it was Bartlett. Locally, most of the Bartlett pears have already fallen off the tree or are a rich yellow in color.

After a few back-and-forth emails, I guessed that it was a variety named "Kieffer".

Then, just for fun, I pulled up some descriptions from historical sources:

About 1855 Peter Kieffer of Roxborough, Pa., planted seed from a Chinese Sand pear tree growing in his yard and generally considered to have been pollinated by a Bartlett tree nearby, from which the original Kieffer tree sprang. Possibly no other pear has been so loudly praised and yet so roundly cursed. For years after its introduction there were bitter battles waged over the blight proof character of the tree and the high quality of the fruit. But now that the smoke has cleared away and the issue is less befogged by violent discussion, the virtues and faults of the Kieffer can be more intelligently discussed.

The large-sized, symmetrical, oval fruits, clear yellow in color, and often blushed on the side next the sun, are attractive to the eye, but the coarse, granular, though juicy, yellowish-white flesh is so lacking in flavor that it is rated by the palate as 'poor in quality.' For culinary use, however, Kieffer has virtues often forgotten or overlooked, for when canned its firm, white flesh is attractive and pleasing. There are rumors from time to time of Kieffer pears shipped to other countries to return in cans marked 'Bartlett,' so that perhaps the very man who decries the Kieffer the loudest is this moment loud in his praise of a canned Kieffer under the guise of 'Bartlett.' 

There is no 'blight-proof' pear. Kieffer is as blight-resistant as any, which amounts in some sections to the same thing as being blight-proof. Nurserymen delight in the free, vigorous growth of the trees, a habit that it does not cease when in the orchard. It comes into bearing young, is resistant to scale, and bears annually and abundantly. In fact, it is necessary to guard against the danger of overbearing, or the reward will be nothing but small-sized fruit. Because of the vigor of the tree and its tendency to overbear, it has come to be the system in sections to stub the trees every year. While this seems to be a necessary practice as the tree gets older, it will be found that the tree will come into bearing much earlier if it can be left to grow more to itself the first few years of its life and then be taken into hand before it gets beyond control. 

As for top-working the Kieffer, generally speaking the operation is a failure. Most success has been with very young trees. Possibly the chief virtue of the Kieffer pear is its adaptability to a wide range, and especially to the warm, dry sections of America, such as the South and the Middle West, where the European pear, adapted as it is to cool, moist regions, will not thrive. The nature of its seed parent exerts itself in its offspring, and the range of pear growing is thereby greatly extended. 

In some years, Kieffers are a glut on the market, but it is noticeable the producer of large-sized, well-matured fruits is neither worried nor affected by low markets. Blight has taken a heavy toll from Eastern pear orchards in recent years, so that the time may be approaching when a higher price will prevail generally. Yet it must be affirmed that where the better varieties can be grown it is a mistake to plant the Kieffer. 

And from another source:

Grown from a seed of a Sand Pear by Peter Kieffer of Roxborough, Pennsylvania. Presumed to be a cross of Sand Pear and Bartlett. First fruited in 1863 and the first Sand Pear hybrid to assume importance. It is the standard by which other varieties of the group are judged. Fruit medium or larger in size, ovate in form, usually pointed at both stem and calyx ends. Skin greenish-yellow in color, often blushed dull red, numerous large russet dots. Flesh gritty, fairly juicy, tender but not fully buttery. Fair in dessert quality, quite satisfactory for culinary purposes. Improves in quality if harvested at the proper time and ripened at a constant temperature of 65 degrees F. Tree fairly vigorous, moderately productive, somewhat resistant to fire blight. -- H. Hartman, 1957.

One magnificent thing about Kieffer pears is that they are hard when they fall and are rarely damaged by the experience, then they will cheerfully rest upon the ground for weeks without rotting. The deer leave them along until after they freeze-thaw and are thus softened. A very good variety for somebody who is an absentee land-owner.

And then, just for fun, an ancient pear called "Pound"

The cultivar originated (was documented) around 1690. Among some of its synonyms are: Uvedale's St. Germaine, Belle Angevine, Pound, and Bell. Pound tree bears very large pears, which may weigh two to three pounds. Because of its weight, the fruit often drops off the tree before it is suitable for picking. The fruit is obovate-pyriform, yellow with pink blush on the cheek. Its flesh is tough, subacid and has poor quality.

Pound is grown in collections for its monstrous fruits. The pears not infrequently weigh three pounds, and one is noted weighing four pounds, nine ounces. The pears are course in form, texture and flavor - but one degree better in flavor than the potato-like fruits of Kieffer and even more sappy... This is a very old pear of uncertain origin, possibly dating back to Pliny, who wrote about eighty years after the beginning of the Christian era. -- U.P. Hedrick, Cyclopedia of Hardy Fruits, 1922.

Another description

Pound. Only valued for cooking. Synonyms: Abbe Mongein, Anderson, Angora, Beute de Tervueren, Beauty of Turvueren, Beauty of Turvensen, Belle Angevine, Belle de Jersey, Bellisime d'Hives du Bur, Berthebirn, Bolivar, Bolivar d'Hiver, Bretagne le Cour, Chamber's Large, Comice de Toulon, Comtesse de Terweuren, Cordelier, D'Horticulture, Dr. Udale's Warden, Duchesse de Berry, Duchesse de Berry d'Hiver, DuTonneau, English Bell, Faux Bolivar, Funtovka, German Baker, Gros fin or long d'Hiver, Grosse Dame Jeanne, Grosse de Bruxelles, La Quintyne, Large Cordelier, Lent St. Germain, Louise Bonne d'Hiver, Pfundbirne, Pickering Pear, Pickering Warden, Piper, Poirie Angora, Royal d'Angleterre, Union, Uvedale's St. Germain, Uvedale's Warden, Winter Bell. -- W.H. Ragan, Nomenclature of the Pear, 1908.

In general, the more synonyms a cultivar has, the longer it has been in existence and the better it is.

Pound Pear. This is one of the largest winter pears, it sometimes weighs from twenty-six to twenty-eight ounces - the form is regular, full and round at the crown, lessening gradually towards the stem, which is long and large - the skin is green, with a brown cheek; it becomes yellow, and the cheek takes a lively red when kept from the air towards the spring; it has a firm flesh, which becomes red like a quince when cooked, for which purpose only, it is preserved through the winter - it is a great bearer; the tree grows large, and is very hardy; these pears should be suffered to hang on the tree as late as possible, they may be kept in bran, chaff or paper, excluded from the air, which preserves their fullness, renders them more juicy and tender, and gives them a fine colour. -- W. Coxe, A view of the cultivation of fruit trees, 1817.   

I have been given to understand that in medieval times pears (and perhaps apples) were eaten cooked more often than fresh. Given the state of dental science, that is very easy to imagine. Hard pears and apples store much longer than tender "table" apples and pears.

Fine Art Tuesday

 

Francesco Queirolo born in what is now Italy in 1704, died in 1762.

Famous for a single work where, from a single, unbroken block of marble he carved a fisherman, an angle angel and the net. Yes, the net is marble on one-piece with the two figures.

The title of the piece (translated to English) is Release from Deception.

"Literally Hitler"

 

What does the accusation "literally Hitler" mean?

The 8 minute video can be put on 2X speed and it loses none of its message. It shows the World War 2 casualty counts as a visual, that is, as piles of human bodies.

In total, Mao and Stalin killed as many of their own people as died in World War 2.

So accusing somebody of being "literally Hitler" should not a cheap, throw-away accusation to make when you are losing an argument.

Paradise

The classical definition of "Paradise" is much humbler than the modern understanding of the word.

The word originated somewhere in the region near ancient Persia and very simply meant a "hidden garden" or a patio-like space that was sub-grade.

There is a huge amount of utility to that design. In arid areas, there are very large swings in temperature between night-and-day, between winter-and-summer. The thermal mass of the ground helped mellow those temperatures swings and reduces the exposure to radiant loading and losses. Having the garden sub-grade also tempered the wind and help retain humidity.

It was common to plant figs or grapes or citrus or other fruits to provide shade and food.

"Paradise" as a simple place of respite from the brutal realities of modern life has much to recommend it. A small space, furnished with people who love you and a few simple things needed for basic comfort.

A couple bits of verse:

Herewith a Loaf of Bread beneath the Bough,
A Flask of Wine, a Book of Verse—and Thou
Beside me singing in the Wilderness—
And Wilderness is Paradise enow.
  -Rubaiyat of Omar Khayyam, Quatrain X 1859 translation by FitzGerald

Some say the world will end in fire,
Some say in ice.
From what I've tasted of desire
I hold with those who favor fire.
But if it had to perish twice,
I think I know enough of hate
To know that for destruction ice
Is also great
And would suffice.   -Robert Frost

A quick physical-fitness update

Quicksilver is living up to her name. She is a pretty good sprinter.

Unfortunately, there is a public road at the end of our driveway. Her game is to say "Appa!", "Appa!"* and when I look up she does the Chicken Run.

My sprinting gait is pretty lumpy due to damage to my left calf. What was good-enough last month is not good-enough this month.

I painted an orange line on the driveway with utility, ground-marking paint that is the finish-line. If I don't get there first...she still has to stop. We are still working on that concept.

Yep, grand-kids keep you young.


*"Appa" is a smash-together of "Old" and "Papa". Quicksilver has her regular papa and she has the senior, classic edition of papa.

The downside of "leverage"

The downside of leverage or "There is no such thing as a free lunch"

If you ever took classes in a Masters of Business Administration program or listened to seminars recorded in a certain era, it was impossible to avoid the word "leverage".

The concept lives with us today as "influencers". The thought process is that if you convince an "influencer" to shill your product then thousands of paying customers will follow them.

Not all skittles and cream

In the physical world (back when I worked), I ran into a downside of "leverage" that I want to share.

I was presented with a problem where the parking brake was marginal for performance.

Federal Regulations require that the parking brake be capable of restraining the vehicle on any road that the vehicle is capable of climbing. Since the steepest road in the United States is/was 30 percent grade, that was the de facto standard. The vehicle might be able to climb more vertical surfaces than that, but the steepest road was 30 percent grade.

Previous efforts to enhance the brake had not been successful. It continued to wobble on the edge of not passing the tests.

The brake was actuated with a lever between the driver's and passenger's front seats. The "build" of the vehicle was to install the electrical harnesses, install the carpet, install the parking brake and then install the center-console over the everything else.

The knee-jerk response of every previous effort to fix the problem had been to increase the mechanical advantage of the cable-drum-lever. That is, they made the diameter of the drum that the cable was spooled onto smaller so each throw of the lever pulled in less cable but was capable of generating more force.

It didn't work.

Hysteresis or slop

The problem was that there was slop in the system.

Too much of the travel of the drum was required to pull the slack out of the system and there was not much left when all of the belly in the cable and the squish of the carpet had been squeezed out.

INCREASING THE LEVERAGE CAME AT THE EXPENSE OF AN INCREASED VULNERABILITY TO SLACK OR GAPS OR HYSTERESIS.

Hydraulic jacks

The common hydraulic jack has a similar problem. It must be much short so it can slid beneath the load and it must be capable of very high mechanical advantage to lift very heavy loads. The problem is that the very high mechanical advantage means that many strokes of the jack handle will be required to raise the top of the jack before the moose-antlers are in contact with the vehicle.

The solution is to have two cylinders (typically telescoping) within the body of the jack. The smaller diameter cylinder is activated first and it moves relatively large distances with each stroke of the jack handle. When it encounters significant load, internal valves "lock" the fluid in the smaller cylinder and diverts additional incoming hydraulic fluid to the larger cylinder. The larger cylinder generates much greater lifting force with each stroke of the jack handle at the expense of much smaller vertical distance-per-stroke.

Another downside of leverage

Investors and businesses use leverage, or borrowing, to multiply the profits they can get from an investment.

If they can invest $100,000 and borrow $900,000 at a low interest rate and then sell their enterprise in two years at $1,400,000 they then pocket $400,000 (less interest paid) on an out-of-pocket investment of $100,000 for an almost return of 200% per year. Not bad business if you can get it.

The downside is when the "market" for flipped houses or widget factories or gaming-software soften and it drops 10%. On paper, the investors didn't lose 10%. Nope, they lost 100%.

If forced to liquidate, they lost every penny.

Quiet heroes

No woman ever wants an abortion.

Frederica Mathewes-Green, a pro-life feminist, once wrote, “No one wants an abortion as she wants an ice cream cone or a Porsche. She wants an abortion as an animal, caught in a trap, wants to gnaw off its own leg.” What if rather than focusing on the freedom of the animal to gnaw its leg off, we focused on getting rid of the traps in the first place? 
 
A 2023 study found that only one third of women described their abortions as “wanted.” In contrast, nearly half described their abortion as “inconsistent with their values and preferences” and another quarter said that their abortion was “unwanted or coerced.” And 60% of women surveyed said that they would have preferred to give birth if they had received more emotional or financial support. Such a “choice” hardly seems free. True freedom for women (and men) lies not in abortion facilities but in pregnancy centers.
 
Pretty good article at the link posted above.

I was trawling the news feeds to see if there were any reports of an up-swing in violence directed at pregnancy centers as happened during the 2022 election-cycle.

That is when I found the article excerpted above.

I know some people who volunteer at pregnancy centers and they are definitely not MMA fighters or the kind of people whose first thoughts are about security or protecting themselves. In fact, the majority of them are little, old "grannies" with brittle bones.
 
 
"Pregnancy Centers" are misnamed. 95% of their support goes to children who are already born. They supply diapers, car-seats, cribs, dressers, "baby-starter" kits, formula, baby food, clothing, books and toys. Their care continues until well after the baby is born. Nearly all of it comes from donations from people like you.

Keep those quiet heroes in your prayers as this election cycle heats up.

"It keeps me very busy..."

 

Andrew Millison is something of a rock-star in the Permaculture (Permanent-Agriculture) community.

This is a thirteen minute video where he walks around his yard and shows you what he is growing.

Smoothly done. Relaxing to listen to and to watch. This video is....peaceful.

A simple caution, he lives in a very friendly climate. There are not many places in the world where one can grow Thimble Berries, Figs and Guava in the same place. 

Don't use his efforts as a yard-stick for your own success. 

Key points: Diversity spans a multitude of dimensions: Plant lifespans, ripening periods, genetic families, resilience to stressors, nutrient profiles, culinary characteristics, vertical strata sun-catcher positions, potential to support beneficial insect/arachnid populations, plant nutrient cycling characteristics and many more.

Sink or Smash Transmissions

 

 

Inside of a 3-Speed, manual transmission. Hat-tip to Gary with a second tip of the fedora to Al for suggesting this video. Gary's comment was "...the video does a great job at starting from simple concepts and showing how it all comes together to form a complex gadget like a transmission."

Circa 1990, the cost to build and install a manual transmission was about $900 more than an automatic transmission. Yet the cost of the automatic transmission as an option to the consumer was about $700.

For a while, limitations of the friction materials used in the bands that locked up the planetary gear-sets in automatic transmissions limited them to about four speeds. That friction material is what "eats" the power created by the engine during full-power shifts while the transmission is between-shifts. As a frame-of-reference, an engine turning 6000 RPM makes 50 revolutions of power if a shifting event takes 1/20th of a second to execute.

Then some genius realized that they could retard the spark for the tiny fraction of a second the engine was disconnected from the drive-wheels and viola! they could suddenly package more gear-sets in a given transmission case. That was only possible because of the computational power inside of the Powertrain Control Module and the integration of Engine functions and Transmission functions.

The guts of the transmission and the software that keeps it alive is totally invisible to everybody walking or driving down the street. They don't see the metallurgy of the gears, the chemistry of the fluids, the friction materials and hydraulic actuators or software... To them it is an inscrutable miracle like the rising of the sun and gravity that is so "everywhere" as to be invisible.

Bits and pieces

I went to a local garage sale today and it got me Jonesing for sturdy, wooden boxes.

Do you want to guess what a wooden box approximately 20" long by 12" wide by 8" deep goes for?

Yeah, a box that is basically made up from repurposed pallet wood. $500 each.

To my readers who were in the military: Please suggest a size-of-box that has a wide range of utility?

Vaguely insulted

There I was, maybe minding my own business, when a 40ish year-old woman asked me if I was comfortable walking on hills.

Looking around me, I asked "Well, that depends. Are we talking 'Michigan' hills or 'Wyoming' hills?"

She pointed at the down-slope at our feet. It was all of 5' of drop with (maybe) a 15% grade*.

"No problem" I assured her. "I might fall but I will be TOTALLY comfortable doing it."

On one hand, the cockles of my heart were warmed that she was concerned about my well-being. On the other hand I wondered, do I really look that decrepit?"

American plums

I picked some of our crop of American Plums, primarily to harvest their seeds. Diploid plums like American plums and Japanese plums are not self-fertile. They need another variety to provide pollen if they are to set fruit. 

Pro-tip, plum flowers are not very attractive to bees. Plant your trees close enouh so the branches of separate varieties interlace. This is not a big deal with European plums (hexaploids) but is make-or-break for diploid plums and their hybrids.

I have cultivar "South Dakota" planted in two places. One place has Prunus americana from the Niobrara river valley in Nebraska as the pollen parent. The other has Prunus nigra as the pollen parent. Of the two, the Niobrara has better fruit quality, so those are the SD plums I am saving seeds from.

A couple of years ago I grafted some AU Rosa into one of the trees (thanks Lucky!) and it bloomed this year but I am dubious about it pollinating any of the SD plums. The AU Rosa bloomed much earlier than the SD.

The flesh of the plums is stewing on the stove and will be fed to Quicksilver. The pits are soaking in water prior to stashing into the refrigerator.

I kind of wish I had some scion-wood of "Fortune" Japanese plum. I think South Dakota (female parent) by "Fortune" would be an interesting cross.

*Percent grade is feet of vertical change per 100 feet of linear road.

"Try it" they said. "It will be fun."

 

What they did not say is that the pin identified with the red arrow slips out under gravity if you turn the trigger assembly sideways. Even without the pin important pieces-parts will stay-in-place until the weapon is operated. Parts fall into the grass, magazines cannot be removed and other "stuff" happens (or does not happen, as the case may be).

It was worth doing but it took two tries to get it all sorted out. For the record, that pin holds two very different bits of gadgets in place. Fortunately, God loves me and no parts were lost.

Short memory?

 

'Something wonderfully magical is in the air, isn't it?' (Michelle) Obama said as the crowd gave her a hero's welcome at United Center in Chicago

'Not just here in this arena, but spreading all across this country we love, a familiar feeling that's been buried too deep for too long. You know what I'm talking about? It's the contagious power of hope.'

News Flash: The last four years was billed by the Democrats as "Obama's third term". If "hope" died and was buried, it by the Obamas and the shadowy figures lurking in smoke-filled, back-rooms of D.C., Silicon Valley and Davos.

A question for the organic gardeners

Hello to my organic gardeners.

I need a quick education regarding "LP powered, flame weed killers".

Problem statement: 5 acres of wet ground must be "weeded" in a one week time-frame. For the sake of argument, the target species is wild garlic with "corms" or bulblets the size of unpopped pop-corn. I suspect that if the corm can be heated to 160F (70C) that most of the corms will be toast. 

My "client" will be advised to use an IR thermometer to calibrate speed of the boom and the valve setting for the burner.

The ground will be wet but there will be no surface water. Corms may be half-buried in mud but most of them will simple be resting on bare soil.

I cannot imagine being able to cover that much ground in that short of a time with anything less than a boom 18" wide. But I really know NOTHING about the technology.

Please advise regarding industrial-quality units and any Flame-weeded 101 documents.


We are not the same

Re-enactment. Back-in-the-day we had to use boulders after we broomed the rattlesnakes from the top of them.

As young baby-boomers, we had to chase down lettuces in the wild and rip their heads off. Then we had to slam the bloody stump of the head against a rock and yank their brain-stem out to eliminate the risk of eating zombie viruses

When I was a young baby-boomer, there were no bags of salad with croutons and bacon-bits and dressing.

If we wanted a Caesar Salad, we had to conspire with a bunch of Senators and stab him to death ourselves.

We are not the same. Gen Z has no idea how hard life was.

Fine Art Tuesday

 

Gustave Doré born in France in 1832. Died in 1883.

Doré is dismissed as "an illustrator" but he did more to bring visual arts to the masses than any other ten "fine art" painters, mainly because he was commissioned to provide illustrations to the Douay-Rheims Bible and to classics like Don Quixote and Dante's Inferno.

In a sense, he was to the 1850-1880s what Walt Disney and Looney-Toons were to the 1930s-to-1970s. He made fine art, the classics and culture accessible to the masses.


 

Michael the Archangel smiting Rebel Angels


Satan vanquished

Dore's illustrations entered the culture and are the norm or baseline for what we think many arch-type characters "look like".

Grab-bag

 Cost of rent

Interesting because prices spiked during recessions which is counter-intuitive. This anomaly might be due to people being evicted or "Jingle-mailing" their keys and competing for the same pool of rental units.

Other factors are regulations that add "content" to units and market pressure from recent migrants.

Climate Change

Blue areas were covered with spruce "parkland" forest 13,000 years ago. Green areas are covered with spruce "parkland" forests now. The distance from Fort Wayne, Indiana to Kapuskasing, Ontario is approximately 600 miles.

Range map American Larch

To put the most optimistic spin on this, nature can be incredibly resilient and make adjustments if the rate of change is not too fast. The corollary to that is that even if there ARE very rapid changes, small islands of "stranded" plant communities exist with the genetics to survive extreme changes. There are hundreds of bogs in southern Michigan, for instance, that contain aspen, tag alder and American Larch.

Range map Bur Oak

There are also countless Bur Oak trees in southern Michigan. Bur Oak, as a species, can withstand drought, heat and fires. It is native as far south as Corpus Christi, Tx.

Things that make you go "Hmmmm?"

One of the puzzles that stumped scientists for a long time was the high mercury levels in some Asian populations AND their high IQs.

The general belief was that heavy-metal poisoning severely impacts intelligence and brain function. Lead poisoning, for instance, is linked to poor, standardized-test scores.

So it was jarring that Chinese, Japanese and Korean populations in the United States had high blood-mercury levels and high IQs.

Cutting to the chase, the mercury came from the fish they ate AND so did the selenium that protected them from the effects of mercury. Moderately high levels of mercury is a problem ONLY if you also have a selenium deficiency.

Selenium, and its organic synergist Vitamin E, appear to have very broad protective effects against a wide range of heavy metals (cadmium, inorganic mercury, methylmercury, thallium and to a limited extent silver with Vitamin E being a rock-star at protecting against cognitive damage from lead) and carcinogenic organic compounds (3-methyl-4-dimethyl-aminoazobenzene, 2-acetylaminofluorene, diethylnitrosamine, aflatoxin, 7,12-dimethylben (a) anthracene, benzopyrene and 3-methylcholanthrene).

If you are getting older and are concerned about mental decline, you could do worse than adding some brewer's yeast to your diet. Brewer's yeast is a good source of selenium since barley grown in the plains provinces of Canada is rich in selenium.

Hit me with your best shot

 

At least two people I used to work with got shingles. Their time-off-work was measured in months. They said the pain was agonizing.

The new CDC "guidance" is to get the two-shot series after you turn fifty. I think it used to be after 65 fairly recently. So here-I-am, just turned 65 and I visited the CDC site and "learned" that they though I was in arrears for Shingles, eligible for the pneumonia series and "am supposed to get" seasonal flu, RSV and Covid shots.

For the first time in over a decade I am not going to get my seasonal flu shot.

In immunogenicity studies, repeated vaccination (with the same strain) blunts the hemagglutinin antibody response, particularly for H3N2.

The same strains were included in 2023 as were in 2022 and only one-of-four strains were changed from 2023 to 2024. So, being in good general health and having already been whacked twice with what they would give me again...I am taking a pass.

I am taking a hard-pass on the Covid shot. I am open-minded about the RSV vaccine. It may be that since we are watching Quicksilver on a daily basis that we already get plenty of exposure.

So there I was, sitting in the chair about to get poked with the needle. The man giving the shot looked like a cardiac event waiting to happen. He easily outweighed my by 100 pounds and his face was mottled with bright reds and yellows.

"Relax your arm" he commanded.

I looked over at him, then down at my shoulder that he had just finished swabbing. I was confused.

"It is relaxed" I told him.

It took me a few seconds to figure out the problem. I have gray hair. Even though I am 30 pounds over what I "should" weigh, I still have muscle definition in my arms even when they are relaxed.

I guess that makes me a weirdo.

Bonus image

I invested my Social Security check in some feed-lot panels. TSC had them on sale, $24.99 for 50" tall by 16' long panel. I will finish enclosing one of our gardens with fence to discourage deer. It won't stop a motivated deer but most deer are lazy and there is plenty of other stuff to eat that doesn't require jumping over a 50" tall fence (with a strand or two of wire above that).

Given even the tiniest amount of care they will easily last 30 years in my climate. That exceeds my "long life expectancy" criterion for investments. It also tags the "bottom level of Maslow's Hierarchy" requirement.

Rule of Threes

  1. Three seconds of stupid can get you killed
  2. Three minutes without oxygen to your brain will get you killed (bleed-out, choking, drowning)
  3. Three hours without body-heat will get you killed (hypothermia)
  4. Three days without water will get you killed
  5. Three weeks without food will get you killed
