I'm still in the planning stages but would like input from some here who have already bought/built planishing hammers. I would rather have this discussion here than elsewhere.
When I got my Gairu/pullmax in Aug, I also got an original CP 528 fender iron planishing hammer with two hand held frames. Runs great. I have a set of Bill Tromblay's Delrin tooling for it that I really like. I want to build a free standing floor frame for this power head, probably about 25 inches deep to match the throat depth of my English wheel. Doubt I'll find an original CP 24" machine and confident I couldn't afford one if it was market price. I would like to mimic the design of an original CB with post mount and adjustability. I've seen pics of the CP floor model with 12" throat that uses this same clamp-in power head. Not expecting to find one of those cheap either but that looks like a viable design to fabricate extended with a deeper throat.
Has anyone got advice from experience, especially something they wouldn't do again if they built another one? I have some understanding about the need for an accurate hit point, but not sure how materials flex, oscillate & lozenging, square vs round vs rectangular vs I or H beam and such things play into the forces related to a planishing hammer. I have looked at some larger floor drill press for base & post and similar construction old equipment for the basic framework to equip with arms made from ?? I can probably source such a machine from scrap for cheap, then add arms. No formal machining capacity here in house- just cut, weld and carving it by hand..
Any advice?
