I have found it. I didn't crack it, it was already cracked. I just made it bigger. There was a splinter of metal that had years wrothof rust built up inside.
I got the ends of the cracks welded up. I didn't know I could run 140 amps through a 1/16 inch tungsten. Next step is hook up the water cooled torch, put in a 1/8 tungsten and collet in there and hit it with 250 amps.
I preheated and welded the crack with 309 filler and the anvil is very hard. I bought some of those knife hardness testers, from Japan to get an idea how hard it is. It's harder than I thought it was going to be. A tig welder running about 320 amps cuts into high carbon steel like a light saber.
Well it's definitely hard. I tested it with my hardness files. The 60rc file scratches it but not very well and the 55rc file slides.
I just picked up about a 2' section of track for 25 bucks at a metal scrap yard . Been wanting a small anvil just for the rare times I need one . I didn't think about any heat/tempering for it . And ,, I didn't even think of having it milled to be flat on top. I was thinking of picking up another piece to flip upside down for a flat surface. Thanks for the thoughts.
I'm building my anvil for the end of civilization. Might as well mill and heat treat it now while I can and fix it or replace it if I F it up.
