Hi all. Here is my design for my power hammer (Ron Kenyon simple air hammer with Larry Zoeller modifications) die. At the moment it is just the base but i run into a little problem/dilemma. https://cad.onshape.com/documents/e3c54a90c5026613737eea49/w/3c2b0ea84d0f4dc883b1228e/e/9e5e7e7e4e0c0513d97797a9 The problem is with the dovetail. Currently i'm using a 50mm diameter, 20mm~ height, 60 degree, dovetail cutter. However, it's angle is way more steep then the angle i see on other power hammers die and bases (ram and anvil). It is very easy to use the dovetail i got since i only have to use one tool to do it and it is pretty fair and simple. However, i'm not sure that it is the right thing to do. How can i cut the base and die dovetail? i do not see any specific tool to do it. The die itself is relatively easy and in the "worst" case i can do it in two parts, one for the dovetail and other for the head itself with the die design. But the base is hard. I can tilt the head of the mill to cut an angle but i will have residual marking and grooves on the base of the dovetail, which i think is not very good. Any idea? Thanks, Mike
Hi All, I just made a smithin magician clone and want to make a die set for it that would let me slit stock so that I could then have a starting point for drifting some holes in it, or use it to set up for making a basket twist, for example.. I attach my crude sketch; the idea is to have the central "chisel" terminate in a 60 degree angle, but the "shank" is more or less straight.. it would accept stock as large as 1 x 1" though I do not foresee doing anything nearly that heavy. I can just make it and try it, but I figure someone has probably looked at this. thanks for any comments!
