I've been reading a lot of posts from way back and there were a few posts by some folks that didnt think gr.8- 7/8"/14 bolts would not work for swaging dies. I did 2 separate tests: one on a section of threaded gr. 8 rod I ordered from McMaster Carr, and a random 3" bolt. I used an acetylene cutting torch to heat them brite red, and oil quenched them both. In both cases they became hard enough that I had to work pretty hard to cut them with a good mill file. I tested them beforehand with the file and they filed easily. Im going to do some more testing. I want to see how brittle they my be. They my not require tempering. I think It would be safe to use for the easy dies to make. I ordered a few of those blank dies from Pacific Tool and gauge to TRY and make a quality point form die
