Here are the plans for the base of the ball turner which goes into the cross slide of the lathe.

Ball Milling Turned. Mill Speed Critical Speed Mill Speed No matter how large or small a mill ball mill ceramic lined mill pebble mill jar mill or laboratory jar rolling mill its rotational speed is important to proper and efficient mill operation Too low a speed and little energy is imparted on the product.

great but one question remains to be answered how did you make the first knob as your tool handle A bit like the chicken and the egg, I must sayGreat job.Thank you.
You can get potassium nitrate for making black powder really cheap, if you can find prilled or hard nitrate. Prilled nitrate comes in little spheres, around 1 mm or less in diameter.
Prilled nitrate is too coarse to use as-is in making black powder and other fireworks, but once you grind it up to about 200 mesh, its perfect.
Keep in mind that potassium nitrate, like most oxidiers commonly used in making fireworks, eventually absorbs enough water to get more or less petrified. But its still good. You just need to grind it up into a fine, fluffy powder again. It never goes bad, even if its gotten wet or has been stored for years.
So learning to grindmill hard chemicals is one of the routine tasks that all fireworkers need to master.
We routinely recommend two ways coffee milling and ball milling. Both ways have advantages.
To grind a single chemical vs. a mix like black powder using a ball mill, fill your mill jar half full of hardened lead or brass grinding media, and 25 full of potassium nitrate. Turn the mill on and come back in an hour. Your nitrate should be light and fluffy. If not, continue grinding it 8217til its fine powder with no chunks or grains.
The good news is that sometimes you dont need to do anything extra like pre-milling. Heres a quick and dirty video I made. It shows how you can even use coarse chemicals and primitive equipment to make black powder just as good as any commercially made BP.
Just so you know whats going on. This is me in my backyard. I am using a homemade ball mill Ive had for 20 years, and Skylighters antimony-hardened lead balls.
Check out my fancy-dancy mill jar Its a one-gallon plastic mayonnaise jar stuck inside a large coffee can for reinforcement. I actually have to tape the screw top on it so it doesnt come off while its turning.
This is down and dirty, almost totally homemade equipment. You do NOT need to be fancy or sophisticated which I sure as hell aint to make great black powder which performs as well as anything you can buy.

A ball turning attachment is really just a mechanism that cause the cutting edge to follow a circular path which is the outside of the ball being cut. There are two different ways this can be done. The cutting edge can turn in the horiontal plane or it can turn in a vertical plane lying along the axis of the lathe..
