OK, it's an 11-year-old thread. But I just came back from an eclipse trip where I checked two telescopes for flights around the world, and the Crawford focusers for both ended up apparently damaged. Both had the same symptoms of rough motion and the feeling that something was badly broken inside. I figured they'd been bashed in with the axles bent and needed to be sent for repair. But thanks to this thread, I tried backing out the low-speed knob, to see if it was rubbing on the inner 1x knob. Loosened it and moved it out 1 mm. Problem fixed on the Featherlight focuser, and on the GSO. Thank you!!
