Finally made a pair of Tongs that works.
I know the material I made them from is not thick enough and mild steel may be the wrong steel .
They hold 3/16 X 3/4 on edge for one of my next projects.
I made the Tongs from 3/16 X 3/4 X 11 in. long mild steel.
I planed to make like a V bit but wasn't enough thickness so arc welded
pieces to the sides.They ended up 16 in. long
They seem to really hold well.
I had to make a 6 tools to make them slip on jaws for my vise, bolster block, chisel, drift, Hofi header tool, cutting plate.
Thanks Ron
