trinculo Posted March 24, 2011 Posted March 24, 2011 I'm getting ready to make up or have made up a set or two of dies for a 100ish pound pneumatic power hammer. The anvil and end of the tup are 6" round and drilled and tapped with two 5/8" holes each to secure the dies. My question is what is the best option for die material and why. I was going to make some 6" round backing plates and weld the dies to them, but I am concerned about the loosing the hardness of the die material or the weldabliity of the $$$ tool steels. I've heard arguments for making the dies from S7 and H13 as well as 4140. I'd love to know everyones thoughts on this as well as ideas to attach the dies. many thanks, Quote
Ranger604 Posted March 24, 2011 Posted March 24, 2011 I know that Little Giant is making their dies from 4140. Look at the LG website. Sid makes an interchangable die set. The base is keyed in and the die faces are hex bolted into place. Might give you an idea as welding is kinda permenant. Just an opinion... Quote
clinton Posted March 24, 2011 Posted March 24, 2011 4140 and use dove tails and keys to keep in place. Why? because this is what works best, also you can get the material pre hardened, saves you having to do the heat treating yourself or sending it out to be done Quote
PMARTINKNIVES Posted March 25, 2011 Posted March 25, 2011 I've used 4340 with excellent results, they have held up very well. Peter Quote
