ballscrew thread

[cherokeechief79]

i have to make a part that clamps around a ballscrew similar to the ones used on cnc machinery.

the form needs to be nearly perfect to the form a ballscrew nut has, but without the balls and its only .500 on the id,a .200 pitch, and 1 inch long in stainless steel.

any ideas on a tap of some sort or some type of a off the shelf tool with this form on it?

its off center but if I had to somehow get it into a lathe I guess I could.

Do you have an extra ball screw laying around? If so, cut off a section and turn it into a cutting tool.

Off the shelf nothing I can think of. Lollipop cutter might work, but without a model or something to see purely a guess.

Cutting an old ballscrew is a good idea.  I never would have thought of that.  You might be able to find a full radius cutter and run a threadmill path.  You have the pitch, what size are the balls?

This is what I'm picturing:
