Looking for lathe / grinder service

I have need to turn the shanks down on some J33 arbors from 1/2" to

I suppose a high quality lathe might do it, but the final run out of the J33 is incredibly critical... Thus the request for a grinding service.

We will hold the 3/8" diameter shank in an ER16 collet eventually so you can imagine the customer will notice run out.

If you can offer such a service and have time to run a few (4 or more) through your shop relatively quickly, then please e-mail my office manager at snipped-for-privacy@autodrill.com.

A location close to MO, USA would be best.

Just mention that you saw this request on the newsgroup.

Thanks and much success to all!
