Thanks, Brandon, for the advice to really, really, clean things before reassembling a Sturmey. One more trick that helps:
I used a little chalk to mark the thread start points on both the shell and the ball cup. That way I could line them up relatively closely, and it threaded right in. One other little trick: the easy way to find the thread start on the ball cup (or other dark, fine, threads) is with a fingernail while rotationg the threaded piece. harvey sachs mcLean va

Hey count Mitzi and I in as S-A dorks screw all those fancy "changers." As far as the double thread thing goes I may be able to help. The trick is to get the threads really clean first, then well lubed, then turn things backwards until they kind of thunk-down from the tips of the threads overlapping. Now just turn in the correct direction and hope. If everything is clean and lubed you should be able thread things in at least a turn and a half by hand. If you can do that you're in, if not start turning backwards again. The double thread thing is a pain and takes practice. good luck, Brandon"monkeyman"Ives holding S-A overhaul seminar every Thursday for the young wrenches at work in Vancouver, B.C.
