What is the biggest ball...

[RandyWilson]

.... tuner you have seen? I may have overdone it.





I figure that in soft material, wood or plastic, where I can really extend the boring head, this should be good for around 5 inch diameters.

It's a shame you can't go bigger. If you could turn a ball bowling ball size and drill the finger holes, you could have some real fun at a bowling alley with one turned out of brass..

Actually, I have an iron ball from a ball mill that is close to bowling ball size and I have been tempted at times to drill those holes.

yep, similar to mine... funny, couldn't find the pieces for it yesterday, then couldn't find the form tools..
Found the form tools tonight right where I left them, in my Kennedy box in the correct draw.. I guess I missed it.

still haven't found the parts to my boring bar ball turner.

Shop gremlins. They do it al the time. If I pretend that I'm no longer interested, they aren't amused any more and they return the missing item.

I bought one of the India ball turners all over eBay for $50 or so. The way it was designed, it would have maybe been the world’s smallest ball turner. I took it apart, considered redesigning, and put all the parts in the “can’t use but slightly too good to throw away” pile. Save your money, folks.

I haven't seen the gizmo what did it, but big ball turners ARE out there... here's the evidence
ball and socket, extra large
