    unthreading cups and chipping paint

    I've seen a number of posters complain about unthreading bb cups - especially those with French with Italian frames.

    My recent French conversion suffered an un-fixed cup on the way home last week. Mechanic has addressed this with teflon tape and cranking on the install. Anyone else out there with right-right thread on the bb with other solutions? Blue loc-tite? Red-loc-tite mixed with antisieze? prayer?

    ffff

    I've heard blue loc-tite used a lot.

    I put french fixed cups on with the mighty Var 30 fixed cup tool. I have never had one work loose, and have never used loctite or any other extras; I just crank 'em on real good. I have installed many a french fixed cup; most of my daily riders are old Frenchies. Obviously, you probably don't have one of these, but talk to a shop or local co-op. Best tool for the job. Far better than a wrench or a vise.

    Gets 'em off real fine, too.

    +1'd. I use the Hozan equivalent.

    I stripped the BB shell of my Miele conversion and I just JB Welded the fixed cup to the shell. Hasn't budge yet. Planning on getting a new frame etc once this one runs its' course.

    it's a common problem. italian and french BBs have regular threading on both cups so they naturally unscrew themselves.

    though i'm sure that fancy cup tool looks like it would solve the problem, loc-tite is an easy and cheap solution and has never failed me on any of my italian frames.
