very interesting ... i have made a similar one, but i have incorporated the use of a small index and a boring head...LOL but this set up is better if ya have time to fab the parts.. i like, nice job, i have a Question tho...
do u have a print of that tap/die holder for your tailstock??
how do you set this up? do u have a measuring system on the turning table and align the center of the turning table with the Z-axis?(considering that the distance betwwen the center of the table and the tip of the carbit, equals the radius of the ball) or is it with trial and error?
There is a far easier way to make this ball turning attachment than this , Buy a small rotary table , mount a simple toolpost and cutter on the tee slots so it is adjustable for radius at centre height , mount it on the cross slide and it will produce a perfect arc every time and therefore a perfect ball , small cheap chinese rotary tables are easily available and it is safer to use as you only have to turn a small handwheel in a fixed position away from the chuck
Such a relaxing thing to watch on YouTube - Which no one would ever get to see on TV, (as TV shows have a set time in which everything must fit)... So thanks for sharing a wonderfully detailed video. :)
Very nice. I have the exact same lathe and only last week made a very similar attachment, except mine rotated on the cross slide without the base plate that you added. I think your idea is much better so I am off off to the workshop to modify mine ;-) Also, it looks like our quick change tool posts are identical as well !
nice work!

Is it not a bit dangerous to hold it like that whilst it's rotating? Could it not end up in limbs being turn off??

@electrogear not dangarous...its just a pice of metal spinning at ~ 800 rpm
this is not ironic...

@TheAllimania I'm struggling to see how in any way a spinning steel ball could be ironic?

Once you polish a knob, is that addictive too?

I lathed a ball once without the ball turning attachment, just the regular tool post and by just eyeballing it.
I stepped up really close dimensions by .0001+ just tapping it with the cutter so it went into a diamond shape, then a hemispherical then a ball.
It was about perfect but 1 side.

Yep, it works. looks ok. But where's your concave capability?
You cut that pretty slowly, with dust like chips, can't you take deeper cuts?
And how about letting people know where you got the plans/ideas used to make it?
Just a thought.
There's lots of other vid's out there too. I'm looking through them all to glean what I can :-)
Cheers.

those are the chips that you get when turning brass unless you take a crazy heavy cut with the lead screw on.

That's brilliant and well spoken, not to fast and very informative.
Do you have any plans to share I'm sure other people would like to make one I would love to make one.
