Idea for ball turner tool-bit holder

<< < (2/2)

winklmj:
I made a quick "prototype" out of aluminum. It works as designed but was designed poorly  :bang: The problem is that it works for cutting balls but not concaves--so I'd need another holder for that. The height adjustment part works fine. Pics after the batteries are charged up.

Wink, you might be interested in this ball turner, which is a modification of Steve Bedair's design. Again, a second toolholder would be needed for concave cuts, but the way the insert is positioned does allow cuts to be taken much further round the back of the ball:

Any pics yet Wink ?

Works ok. Needs a sharper bit.





I've made another "traditional" holder for a square 3/16" bit. It works but needs a bit of packing to get it on center.
