A few thoughts on liquidation venues

One of the hallmarks of a robust ecosystem is that every joule of energy, every ion of potassium, every molecule of amino acid is hotly contested for by a multitude of "pathways".

Picture from HERE
When a towering forest giant falls in the rainforest it is attacked by termites, ants, worms, grubs and thousands of species of fungi and bacteria.  The nutrients that were part of the giant are quickly freed and become available for other trees.

One might look at a tropical rainforest and assume that the soil must be exceptionally fertile.  That is incorrect.  Nearly all of the nutrients needed for plant and animal growth are already claimed, locked up, in existing growth.  The rapid growth of plants in natural, tropical regions is a tribute to the efficiency of the termites, the ants, fungi and bacteria (carrion eaters, dung beetles, flies, ad nauseam).

Economies


Economies also need recyclers.

In the home economy, clothing becomes obsolete as children out grow it.

More affluent household pursue ever more capable game systems and computers, thereby making their perfectly functional "old" system obsolete...at least to them.

Sometimes a hobby is given up and all of the support equipment is no longer needed.  Perhaps a truck was sold and the former owner has a cap or a tool box but no truck to put it on.

People die and leave estates that need to be liquidated.

People fall upon hard economic times and need cash-money.

Sometimes people just decide that life will be better if they deballast, streamlining and simplify their lives  (Example of a fellow blogger streamlining).

Businesses face all of those challenges as well.

Asset liquidators create markets.


Auctioneers

Auctioneers advertise.  Their name recognition pulls a clientele of bidders. 

Auctions set a price for an asset when the "second" bidder stops bidding.  The first bidder might be willing to go much, much higher but the price is set when the "second" bidder drops out.  Another dynamic is "feeding frenzy".  Both of these dynamics are enabled by a crowd.  A good auctioneer will play that crowd like a finely tuned fiddle.  A little bit of razz-a-ma-taz.  A goodly bit of sing-song.  "Yuping" and "barking".   A few corn-ball jokes.  Little snippets of information about the item being sold.

Virtually anything can be auctioned.

Free entertainment at its finest.

Thrift shops

Thrift shops either sell on consignment or take in donations.  In many cases, those donations can be written off on one's taxes.  Usually, donating "stuff" is more a matter of reclaiming space than doing awesome acts for humanity.  Whatever the reasons, thrift stores are an efficient conduit of goods from those who have much to those who have less.  My brother the accountant tells me that every square foot of space a home owner frees up is worth $70.  That is big incentive to clear out "junk".

Mrs ERJ recently slipped a book into my reading pile:  Thrift Store Saints, (Meeting Jesus 25 cents at a time) by Jane Knuth.  Jane started volunteering at a thrift store in Kalamazoo, Michigan in spite of massive trepidations.  The book is a compilation of 19 short essays on lessons she learned along the way.  Jane has a gift for capturing "people" with short sentences and simple words:
"She shifts from foot to foot glancing around hopefully at the racks of used clothing in the store.   Her medium brown, straight hair is tied back severely in a ponytail, seeming to stretch the worry lines on her forehead and at the corners of her mouth into deeper crevices.  She wears no make-up, and she is of the age where makeup helps a great deal."
Thrift shops create a market (i.e., develop a clientele) by selling a consistent set of "products" at predictable, low prices.

Pawn shops

Pawn shops are a combination of bank and resale store.  A good pawn shop is like a Christmas tree afloat on a sea of surprises.  A bad pawn shops smells of despair and good clutched too long, too tightly.

Pawn shops have two markets: bargain seekers and the person who pawned the goods.

Mechanics and retailers of durable goods

Mechanics, gunsmiths and retailers of durable goods can be good venues for shoppers.  Repair people have insights into how well the previous owner takes care of things.  They often know the maintenance history of the item.

Sometimes a screaming deal can be found by giving a young mechanic a couple of St Pauli girl posters and a case of good beer....just to keep their eyes and ears open.

Private liquidation venues


Garage sales

I love them.  Mrs ERJ tells me that I cannot buy more stuff at a garage sale until I lose some of my stuff.

Gifting

Growing food producing trees is one of my hobbies.  Much of my stuff, maybe even most of my stuff, originated as "gifts" from other growers.
Acorns from Lucky.  These acorns are HUGE by local standards.

Just last week I received a package from Lucky in Kentucky.  The twigs may have been twigs he had to prune off anyway.  The acorns and nuts may have been slip hazards that he had to rake up anyway. For the most part Lucky is in "pay it forward" mode.  He just asks that those who receive his gifts be open to doing the same.

Bach Steel (small business report)

This week's small business report is on Bach Steel, a small, specialty steel company in Holt, Michigan.  Bach Steel (517-455-4443) was started in 1997 by Nels Raynor after working several years as a steelworker.  Nels knew he was a "hands" guy from a young age because he would spend his entire weekend helping his dad in the ceramics studio.

Due to customer demand, Bach Steel now specializes in the restoration and moving of historic steel bridges and ornamental, wrought iron work.

Ornamental work



A closer look at the detail



Ornamental work is not the largest part of Bach Steel's operation but it has to be one of the most satisfying.

Bridge work


Nels will tell you that Bach Steel does restoration.  Their restoration work does not change the visual impact of the bridge in any significant way.  There will not be a bunch of welded on, historically incorrect cross bracing.  But the bridges will be safer and, in many cases, moved to new locations and "repurposed".

Nearly all of these photos are from the Bach Steel website, with Nels Raynor's permission.

This photo came from a gallery that has many pictures of the rigging used to move bridges.

This is not an office job.  Picture from this gallery.  This bridge is in Portland, Michigan.
Eyebars are one of the most critical components of "structurally determinant" truss bridges.  The lower ends tend to have more corrosion due to poultice accumulation and they stay wet longer.  This end has been bead blasted and rough ground to open up areas of crevice corrosion.  This will be filled with weld metal and ground flush.
Different part, same bridge showing how weld metal is used to build the section back up.  This picture and the picture shown above are from this gallery.
Sometimes the eyebars are too far gone to save.  No problem.  He will just forge new ones.  This is from a bridge that was restored in Robertson County, Texas.  Gallery here.
Bach Steel does penetrant testing for cracks.  Most of the bridges he restores were built between 1870 and 1900.  They used hand forged, wrought iron eyebars.  Those weld seams show up as a crack on ultra sound testing or magnafluxing because of the silicon inclusions in the joint. It takes experience to know if an anomaly is a fatigue crack or an artifact of the production technology.

Mr Raynor estimates that restoring a bridge adds another 50 years to the bridge's functional life.  There nothing wrong with the design of these bridges.  After all, the youngest bridges Bach Steel restores are 115 years old.  All they need is some tender, loving care.

One point that Mr Raynor is passionate about is the use of wrought iron in some of the critical applications.  Wrought iron is very high in elemental silicon.  Modern steels use oxygen to burn off the carbon and silicon...then alloying agents are added back in.  With the exception of a few grades of tool steel (O6 and S5, for example) modern steels have very little silicon in them.

Silicon modifies the oxide coating on the steel.  The oxide does not become rust, but rather, clings to the base metal in a dense coating that resists further corrosion and pitting.  In a sense, wrought iron is a dark form of stainless steel.

As a steelworker who specializes in historic bridge restoration, he is very conscious of just how good wrought iron is for exposed, structural applications.  115 years of corrosion leaves a mark.  You can see what lasts and what does not.  He also knows that there are not that may people out there who are comfortable working with wrought iron or have the expertise to hand-forge custom hardware.

A critical part of bridge restoration involves rebuilding the roller nest.  A hundred foot span of bridge will change in length by 1.5" between winter and summer.  Depending on the arch of the road, loads can also cause the length of the bridge to change.  Note that this shoe and roller nest were constructed with vintage correct hot rivets.  Photo from this gallery.
The other end of the bridge rests on something that looks like this.  Note, this photo is not from Bach Steel.

Bridge Reuse

The greenest way to recycle something is to reuse it in its original application with minimal "reprocessing".  There are many, perhaps hundreds, of historic bridges that are available for repurposing.  In some cases they were too narrow to meet increasing traffic.  In others, there were concerns about the pounding they would receive from commercial trucking.  They are still more than sufficient for pedestrian, passenger vehicle and light truck use.

WAY cooler than pink flamingos!  Yes.  You could have one of these in your yard.

Bach Steel (517-455-4443) provides an excellent essay HERE on how to get your very own historic bridge.

If the science of structural failures interests the reader, Why Buildings Fall Down: How Structures Fail is a very good read of real-life failures in the field.
