Well, I can blame it on Kirkster70!!
Since I have quite a collection of 2"x2"x1/8" angle Iron that my son salvaged for me from a completed construction project, I use it from time to time but finally a project came along that really was suited for it. If anyone is interested in the plans, I could post a link.
Essentially it's a 17" vise used for forming sheet metal panels. The three eye bolts are actually the clamp bolts for the top piece of angle iron. I welded some nuts on the framework and the eye bolts screw through them. It was a fun little project and when it gets warmer, I use some rattlecan paint on it. I also built a 24" sheet metal brake some years ago from some heavier angle & channel iron that I'll post pictures of sometime.
