Hi Guys
I put together a ball turner with common stuff that most all of us allready have in the tool box.
I allready have a 2 inch and a 3 inch boring head that I commonly use on the mill, either will work. Both of mine are just the cheapo import variety with the screw on arbours, either R-8 or M/T. I bought a M/T arbour from the local Busy -Bee for I think was $16.00 . I mounted it to the boring head, then just chucked up in the 4-jaw , and machined it down to 3/4 inch. The AXA QCTP sets come with a toolholder for 5/8 boring bars, and I just removed the sleeve, and the ID is 3/4.
The only Parts I had to make was the Handle, the piece to bolt on to the modded M/T shaft, and a stub to hold the cutting insert.. Only three parts in total, as the boring head, toolpost holder, was allready in the tool collection anyway.
This type of ball turner will get up really close to the chuck, and will also make concave/convex cuts to the ends of shafts.
The tool was allready sitting there anyway, and all I had to purchase was a 16 dollar arbour, and a few bits from the scrap bin, and I have a use full tool.. Whipped it all together in about 2-hrs time. Quick n dirty way to get making balls.
So, for the guys that dont care to make the hole tool, and just want to do the min, this is about the fastest way, Ive found.

Thanks for looking
