petere76. for the fullering dies, I started with round stock, 1 1/4 inch i think. cut to desired length of the die, took a heat and flattened them down to the desired thickness ( about 5/8 to 3/4 inch maybe, i didn't measure. ) then ground the bottom flat ( very hard to get parallel ) a mill would be great for this. the top radius was then
flattened down on the grinder to oval out or dome? not sure how to explain. I then bolted two plates to the tire hammer disengaged the head so that it would fall and used a clamp to align and tack weld the two dies to match on the plates. then removed and finished the welding.
as for my punch, there are a few write ups on how they work. search the forum for it. personally my punch is smaller and I finish up with a drift. the drift is left in to flatten the cheeks during the process. it does do a little of punching and drifting as you stated. :) hope that helps.
fuzzy smith! my swage block has been used mabe twice since i bought it a year ago LOL. but since i built the stand i have used it to shape the round die on my hammers , works a champ only problem is keeping the side you hit on the hammer square as i don't have a striker or extra hand to hold a flatter :)
