[QUOTE=Canobi;98470]Depends on skill level + knowlege base, both of which are under construction in my case

Be that as it may, I came across a really simple design the other day that even my novice skills can turn out, so I'm working on one right now

There were no drawings of it I could find so made my own as a guide and left the numbers off as it can be scaled to suit. Credit goes to randyc (practical machinist forum) for the concept design:


Here's where I'm at with it so far. The shank is bright mild that is press fit into the main body, which is made of 306 stainless:




When I saw Rotary Broach mentioned here I looked them up, as I'd not heard of them before. Very cool! But the retail prices for the holder, the part I see you are making, are crazy expensive, especially for a tool that won't see frequent use as a hobbyist. So I am very interested in your project! I see the actual broach bits for these holders aren't too unreasonable. So if I made a holder, I could see owning a few bits.

I was wondering how they accomplished the wobble. Your drawing explains that. Did you turn the 1/4" ball, or is that a bearing ball you bought?
