Cutting an Arc
« on: May 14, 2019, 09:24:09 AM »
Anyone have any suggestions for a mill attachment/accessory for cutting expanding arcs ?
I'm looking for a way to cut an expanding arc pattern much like centrifugal pump  rotor vanes.

Not totally necessary, but sure is a good excuse to buy a CNC mill and or 3D printer ;)

Wow.   Looks like a lot of skill and work to get it right on a manual cranker. 
So tell me - What's your fair share of everything I've worked for??? Nothing?  Correct answer!

I'd get the first one right, and the last will not even be close.  Where did I screw up?
