A planishing hammer is an ultra simple machine in principle. It’s basically just making the same hammer strikes you would with a body hammer and dolly, but doing it way faster. That way you can move it around to shape metal by using it to shrink and stretch it. In this video a dude takes some cheap air hammer planishing bits and makes an adapter to fit them to his Milwaukee M12 Palm Nailer. He doesn’t want to modify the palm nailer. If it were me, I would modify it myself and not care, but realistically I’d also probably be doing it with an air palm nailer from Harbor Freight because I’m poor.
So I’m going to use this as inspiration to build my own once the shop is done. But I want you to do it yourself as well! So build one of these, using his project as inspiration, and then let me know how it works out.
Video Description:
Follow along as I turn this Milwaukee M12 palm nailer into a planishing hammer that can shape sheet metal.
I’m a hobby sheet metal artist and i could really use this thing, but I don’t have machining skills, access to tools, etc to try my own hack.
The guy at Full Steam says he has the file on his site to do a 3D print of the collar for his hack, but it’s not there, and he doesn’t answer my email to him. I wanted to see if there’s any chance you might have located that file.
Since I’m not going to try doing my own hack, I’m thinking about just buying an OK quality short barrel pneumatic hammer with a pressure regulator and a trigger speed control and sticking a hammer bit in it. I’m no expert but I’m thinking maybe that would work?
