Non standard threading question

[Ronthomp]

I am modeling the thread adapter bushing and want to use the model to generate threadmill tool paths.

The bushing is M52 x 1.5 on the outside and M50 x 1.25 on the inside.

I did the outside with a thread strategy with no problem, but the for the hole, 1.25 pitch is not listed. Is there a work around? Or can I threadmill without it being modeled?

Thanks!

Search the forum.  There are lots of threads on creating custom thread.

Thanks, I figured it out. The answer for me is don't model it. The cam can cut whatever thread pitch you type in.
