Ive been using a router and milling my threads in my shafts for awile. A fellow brought a cue to me and the shaft had been tapped for a radial pin. The tap job was terrible. Loose and very rough inside. Im surprised the cue maker who I won't disclose, let the shaft out of his shop like that. Anyway, I thread my own shafts 3/8 10 with my mill and the threads are great but I have never tried a radial pin. Has anyone threaded a radial pin. Seems to me its just 6 or 8 threads instead of ten. Thanks for any advise.

I've personally never threaded with live tooling, but I don't think its possible to do what you want unless you are on a cnc lathe.

The reason is the pitch on the radial made by Uniloc is not on any lathe. Its a decimal number. I remember I measured it a few years ago and it was not metric either.

Besides the pitch problem, you would have to grind your own tooling to match the tooth profile.

I'm surprised the threads were bad. I've tapped with the radial tap on a few shafts (not nearly as much as other cue-repairmen), and I thought it made the cleanest threads by far using the tapping method.

He knows the Pitch. 7.62??

I used 7.5 TPI (If you lathe has that) and single point threaded my "Homemade" Radial Tap...
Before I bought the Radial Tap from Atlas.

> The pitch is 7.634 according to Bill. This means your cutter would have to be .1309 to cut the threads to the correct shape,otherwise there might be issues with your tapped threads.

It could be done using live tooling,such as on a 3-axis CNC lathe,but as I mentioned,your cutter HAS to be .1309 for the form to be correct. Tommy D.
