Board Jack

[Dave Lehnert]

Found this Board Jack at a local Antique Mall. Looks like it has seen very little use. At first I was wondering if it was a commercial made product, but it has markings on the feet like the maker was considering changing the profile of the feet. (in one of the photos below) It is very well made. The hinges are brass 3/16" thick. If homemade, odd that the pins are peened over vs using a bolt, nut and washers. The pins are covered what looks like copper pipe. The wood is maple 1 9/16" thick. 34" tall.
A search on the net for "Board Jack" did not turn up much. Is there another name for a Board Jack?
Were there any commercial made Board Jacks?
Anyone know if there were a set of plans in a magazine or the like this may have been built from?

They are great vise companions. I've seen at least one plan ,can't remember where. Sometimes referred to as "slaves",that might help you find it.

Dave.....look in The Workbench Book by Scott Landis.....that is a type of bench slave that closely resembles one made/used by Frank Klauz.....there is a diagram of the slave and Frank's bench in the back of the book.

The cut away area is the part that makes you think they started to modify the base ?
No that is so the base does not teeter on some shavings or rough floor.
An extreme example is my shop light stand with the bent steel rod legs.

As far as rivets instead of bolts. Nuts always come loose on bolts if used that way unless the ends are peened over so the rivets are theeeee best way to go.

Yes I bent those from straight rod and welded them up. The previous base , this is a microphone stand so is hight adjustable, teetered all the time because it was just a flat on the bottom disc of cast iron. As you can see I always have a significant amount of debris under foot; wood or metal bits so this base easily spans it all and is super stable AND LIGHT WEIGHT to carry around. These bent rods were scrap from a metal fence job I did for a restaurant. Once I was done attempting to spray paint all that skinny rod that went into making the fence, primer and color coat, I had a new appreciation of the powder coating process (uses electro static to make the granules stick all over) and industrial paint booths that can do a similar thing with wet paint.

PS: oh, you said "marks" on the feet so you probably know what I just posted but oh well.
Nice find in the board jack !

Sorry, I did not post the photo I was referring to. I just tried and for some reason it failed. Guess I did not notice it yesterday when I uploaded the other photo's.
