I made this part on my old Logan lathe. Could it be made om a cnc mill?

IT IS A 3/8 BALL IN A 5/8 BALL IN A 7/8 BALL IN A 1 INCH CUBE.

I wanted to see if I could make a 3/8 ball in a 5/8 ball in a 7/8 ball in a cube. Here is the result.

I am having the same problem with Photobucket since I went with the new upgrade.

I don't know why Photobucket will not zoom pics. But you can go to my Photobucket site to see my junk. jims_03

http://i86.photobucket.com/albums/k106/jims_03/IMG_0002-11-1.jpg I'm just an old retired machinist so I don't have CNC lathes to play with so all these parts were made on a old Logan lathe and all tools were ground by hand with a bench grinder and lapped on the Logan using grit from the grinder mix...

I am going to make some more cubes with a ball in a ball in them. In fact I am going to try to make one with 3 balls in it. I don't know if I can
hand make the form tools small enough but it will be fun to try.
