My experience with repairing cast iron consists of armchair quarterbacking of Youtube vids. With that behind me, and remembering I had some leftover nickel AC rods from an anvil "fix" that was fugly, but functional, I felt I had the street cred to fix what I broke.
I'll start with lessons learned.
1. DON'T, use a 6ton bottle jack to persuade a cast iron vise (see pic)
2. DON'T use a 4ft cheater bar on an already beefy and oversized vise adjustment lever
If you fail to head the first two warnings, do wear ear projection for the upcoming SNAP, and ensure your life insurance policy is up to date, because your heart rate WILL increase as a result of "what just happened"?
Fast forward to the fix, where sandblasting prepped the surface, appropriate pre-heating was used, small sections of repair beading, and welding both the inside and outside, followed by a slooooow cooldown on a very warm 116 southwest AZ day.
She's in machinery grey now, replacing the (apparently) Farmall red that was the OE, coat, but it was resprayed a very fetching "Lost in Space" aluminum spaceship color.
Pics of what the Cole vise is all about, tho mine has zero markings anywhere.
