after noticing a bit of play in my bb after less than two weeks of casual riding, I made a bb fixed cup tool like the one described on sheldon brown's website, from a flanged bolt, nut, and some washers. It worked amazingly well, way better than a set of pliers and a lot of cursing. I don't know if he invented the implement, but genius nonetheless.
My question is this- I have an old raleigh bb. The fixed cup has a raised ridge across its middle, no wrench flats along the perimeter, and no lip whatsoever. It doesn't seem as though there's anything to indicate when I should stop screwing it in. I pretty much stopped when the tops of the ridges were level with the shell face, leaving a millimeter or so between the face of the cup and that of the shell, but it felt as though i could have threaded it in even further, like i could just keep turning it forever practically. It seems as though its in maybe a bit too deep as it is? So, for a cup like this, how far in should it ideally be? Also, while i applied much more torque this time using sheldon's, um, device (was going to say tool, ha), without any kind of contact between a lip/cup surface and the shell face, I don't know that this is enough to keep a reverse threaded cup from coming undone again sooner than later...is loctite a must for these kinds of cups? thanks in advance
