oh no another ball turner

[j45on]

It's done  well nearly I have no stock to make a handle 
Actually I need stock for the ball as well I only had delrin
I quite like the half exposed cap screws so i'm not going to shorten them now


Ralph I went with the 16mm tip in the end so now I have 11mm and 16mm tips I will have to make something else to use the 11mm ones 
And I had read your posts on building the mini ball turner and fitting the tip 







Thanks for everybody's help

Spot on Jason  does the job well, never turned this delrin stuff but it looks a very smooth finish 



The tip looks spot on in there, you won't be disappointed with the cutting capabilities of them. I cut a lot of stainless with mine and it works a treat


Glad you found the post, I couldn't remember which one had it in 

The 11mm tips can easily be used in a smaller tool post for finer work or even make some new turning tools? I've still got 5 of them myself.... I'll use 'em one day?




Have fun with the new addition, post up the rest when you have the stock

Finally finished 
I found one bit of aluminium big enough for the ball and a bmw at work donated it's antiroll bar link arm for the handle (not very bling but it was free )
And finished with a bit of scotchbrite for a brushed/satin look



Then I decided to make a small one ( I only have 1' aluminium bar at the moment must go shopping )
And I thought I would buff it up a bit using a piece of sponge/foam and some polish I bought ages ago but never used 
I was impressed I might polish the big one as well now

Nice!   


That's some mighty fine looking balls you got there Jason          (childish? Yes... but I couldn't resist  )


Looks really clean when polished up too 


You'll soon be unstopaball        I'll get me coat.....

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. 

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

Nice job Jason!

That ball came out very nice.

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.
