Soldering jig

[stevec]

On the subject of the jigs we love, I picked this device up at a friend's estate sale (his Dad's estate).

   

First time I used it and I'll definitely be using it again. I put it around the 4 pieces and tightened it up, checked with a square and all 4 corners were 90°. Pretty slick.
I'll be using it for picture frames and any construction of squares or rectangles.
I won't mention any of the other stuff I picked up for fear of a .
