RF-30 Clone Head Alignment Guide
Rob,- Now you have me going again, mine has two belts. Does three mean you have a power quill down drive?www.hobby-machinist.com
Thanks - just ordered the set. Shipping on the studs was nuts from McMaster Carr so I got those from Amazon.Here you go, man!
I don't have time to teach everyone how to fish, so here is a free fish!
They make a substantial difference in holding power, not to mention applying even clamping through the spherical flange nuts. Fixed my problems for good. My friend owns my old RF-31 now, and he's happy with it too. Fairly cheap fix. Let us know how it works out, sounds like you are seeing the worst of it (head movement) on your end.Thanks - just ordered the set.

I have had my RF30 clone for more than forty years and never had a problem with not being able to tighten the head clamping bolts. I would pull the bolts one at a time and check/chase the threads. The nuts should spin on freely. While they're out,check the length of the thread. The P.O. may have replaced them with bolts with a shorter thread length. My bolts are 9" long and have 2" threads with a little less than half engaged. Finally, check the gap between the split halves for an obstruction that would prevent clamping. I tighten with a 13" box wrench. Typical torque is 30 -35 lb.ft.
