Tom, I have found the safest means of unscrewing the two-piece motor barrel arbor assembly is to re-assemble the large winding wheel ("F") to the barrel arbor, that gives you a "hand" on one end of the arbor assembly. Then grip the barrel itself (with a soft clamp) and you should be able to "break loose" the threaded arbor assembly.
