Ball turners.

I don't think a lesson in bad manners is an appropriate use of this forum.

No, it's quite clear that "your folks" taught you how to be rude and condescending and trying to belittle other peoples comments.

This forum is a friendly group so take a chill pill before you blow a gasket.

Ahem! Coughs politely. Now then, gentlemen...

I do like that worm-drive tool - gives accuracy and good looks!

If a lever-action ball-turner produces eggs and acorns when not centred accurately, might that be an advantage in some work, by appropriate setting?

.

(There is, by the way, a method for milling ball-ends, using a boring-head or fly-cutter and rotating the work on a rotary-table or dividing-head with its axis suitably inclined on a plane parallel to the machine table; but I don't know the necessary geometry for the required diameter and angular extent.)

Tony,

As a moderator I've noticed your later posts are unnecessarily abrasive. Please keep it civil.

Thanks,

And there is a message waiting for you from me.

Thank you Moderators

I'm neutral on the subject of ball turners; I don't have one, and don't need one.

I was intrigued by Vic's powered ball turner. I wonder if it can do concave curves? And if so could it be adapted to cut a double enveloping worm?

The problem I find with a lot of ball turners, even Bernard's one is there is a lot of the tool rotating beyond the radius needed for the ball so you end up having to form the ball a long way from the chuck/collet.

The ones that use a boring head type arrangement or even Andrews copy attachment can generally get in a lot closer which saves chatter or having to have a thick stick on the lollypop shape being formed.
