    Is this reasonable?
    I have a spare adjustable bridge with threads on the top half.

    Can I thread it into the bottom half and reverse the adjuster’s direction without problems?

    My reason for doing this is for a full circle pu. I have tried the full circle both ways (on a different bass) and I think I prefer the sound of it facing the strings as opposed to the body. I get more articulation out of it facing up it seems.

    Ok....But why exactly....Just so I know why this is a bad idea.

  4. Simply because the diameter of the unthreaded end of the adjuster is is about 1/4". A 1/4" x 20tpi tap (the size of the full circle threads) would just about slide into the existing holes in the bridge feet. To cut theads in the bridge feet, you would need holes no larger than about 3/16".

    And if you drill out, glue in a dowel, and re-tap, the threads will not hold. Been there, done that, then cut a new bridge...

  7. Anybody ever try putting a Helicoil in a stripped bridge thread?

    You mean there is a valid application for D'Addario strings?

    Could cutting a new bridge be cutting the feet off of another bridge and drilling them out?

    Arnold,
    Have your tried using the thin super glue to strengthen the thread? I do this and run the the wheels in and out a few times...quickly :)
    Kevin I wouldn't recommend that you do it. By the time you buy the tap, make a jig for the bridge, drill the holes, and screw it up a couple of times, you'd been better off seeing your luthier.
