Great idea. Thanks for sharing.
Glad you liked it. Those replaceable tips do look like hex keys. Turns out they pretty much are. It is also pretty easy to grind that reverse cone into them too. Easier than I initially imagined it would be. You never know with some things until you give it a try. I bet someone could even do it with a hand held drill clamped to a bench if they had to. Now that I'm thinking about it that may be the best way to go? 3 jaw chucks hold 6 sided stock good. The math just works out.
