oh no another ball turner

<< < (7/7)

Tinkering_Guy:
I've been noodling around with designing one of these.  Why be different?  Because I want to be able to have very fine control of the diameter (like down to the thousandth, at least).

So far no definite conclusions.  :bang:

I'll post when I actually have something other than vapourware..

Brass_Machine:
Nice job Jason!

That ball came out very nice.  :bow:

The boring head type is probably your best bet for that level of accuracy.

Tinkering_Guy,

In the Nov./Dec. 2003 "The Home Shop Machinist" is a multi-part article on making a ball turner by Robert Bailey. It looks like he has the tool moving on a dovetail slide to advance the tool. Think of haveing the tool on the top slide and using that as advancing the tool by a certain amount.

I'd love to scan the pics but it would violate copy right.

Bernd
