After discussing with Bintel it seems this issue is fairly common with cheap Crayfords and is a result of minor damage to the rotating pin and/or the bearings. Apparently the cost of trying to fix it wouldn't be viable, assuming I could even find someone to attempt it.
So I'm on the lookout for a replacement. Wonder what the chances are that someone has upgraded their Stellarvue focuser and kept the old one? Time to to post a Wanted ad...
