 :clap: really nice with that extra wide "foot" you have !

But height isn't very easy to adjust - OK, it's only ones you have to do it so ...

Nice peace og tool - now make a video of Ball turning  :drool:

Evening :)

Well I have had a good afternoon , perserverance paid off and my inaugural ball has been cut!

I made a couple of blanks pre-drilled and tapped to 10mm and an arbor with a 10mm thread.

My first effort is on the end of the leverage arm, here -



Its a bit of an olive shape I know.

The second one here, more of a ball shape as I started to work out how to get the best cut -



A couple of things need to be sorted out. I think the slightly olive shape is where the arbor flexes due to being a bit too thin at 10mm diameter. Also the tool sounds like it is rubbing when moving from 6 o'clock to 9 o'clock.

Will investigate tomorrow but for tonight I am feeling triumphant!

See?  Told ya it was fun to cut spheres.  Nearly as entertaining as getting an engine to fire up.
ksor:
No - the olive shape is because the turner is NOT placed exactly vertically under the center of the chuck (maybe wrong spelling of 'chuck') !

Exactly this placing differently you can use for making different decorations - convex and concave - but to make a ball you have to place your tool very accurately under the center of the chuck.
