[TheForge] Twisting Jig

[Peter Fels & Phoebe Palmer]

Mike; The 2 mounted wrenches  hold 2 points of a hot bar from twisting.
The handheld, double handled wrench is used to twist the bar between the 2 mounted wrenches.
That results in 2 even reverse twists between the center wrench and the 2 outside wrenches.
One side of the mounted wrench pair slides and locks in place to set the length of bar to be twisted.
To do the same job the old way takes twice as long and is hard to get the opposing twists symmetrical.
Our CBA rag just showed a version of the same tool with different sized parallel slots instead of adjustable wrenches.

I get the adjustable wrench with the added handle/grip but I don't get
the jig.

How's that supposed to work?

I found Ron's comments on it:

   The adjustable length twisting jig is a very useful tool for
   making double reversed twists in various sized bars. It will allow
   you to make virtually perfect twists every time, if you have the
   bar evenly heated when its placed into the wrench jaws. I like to
   use an old "Ford wrench" to make my double handled twisting
   wrenches out of. Using a double handled wrench will allow you to
   apply an even force to the bar and not cause it to be bent out of
   alignment during the twisting process. Be sure you use the right
   kind of welding rod when welding the high carbon steel wrench
   heads to the jig, or the welds will break off the first time you
   use the jig. I use "UTP-65" for all such welds, expensive, but
   worth every penny. Also, because your hands rotate under the hot
   iron during twisting, the hot scale that falls off will land on
   your hand and wrist. Beginners usually find this uncomfortable,
   but you will soon get used to it, and it causes no damage.

but I still don't get how thw jig works.
