Bridge Pins – distance to neck

    On an old troubadour, I am hoping to change out the brass L&H Levers with Delacour levers. I have installed Delacour levers before and know that the bridge pin is set much closer to the neck than the L&H bridge pin. This change on the troubadour would bring the strings closer to the neck. My question: is moving the plane of the strings okay?

    Yes. Moving the strings closer to the neck will reduce the torque on the neck and prolong the life of the harp.

    I finally got the courage to start this project.  What I ended up doing is cutting the bridge pin shorter.  Do you think this is acceptable or would drilling the hole deeper be preferred for a particular reason?

    I’d drill them deeper and while at it use threaded pins.  Depends on the original hole of course but in any case I want at least half the pin length below the wood surface.  Any shorter and there is a good chance of them getting pulled out of line.

    I have never seen these called bridge pins. I think they are stationary nuts.

    “Sometimes you feel like a nut – sometimes you don’t” as the old ad says.  I have only heard of a nut on guitars, violins, and similar.  It goes with out saying that they are stationary.

    This is what I mean by “threaded bridge pins.”  I like the hex headed ones shown here from Dusty Strings; there are other types with different heads.  The threads make it much easier to set the length than the older type with smooth shafts.  The hex head lessens a chance of burring compared to slotted or Phillips heads.

    The new levers came with threaded bridge pins, but the problem is the diameter is smaller than the existing hole.  I did examine that the cut bridge pin still has a tad more than half of its length below the surface as suggested.

    Well, I guess you have a choice Sidney.  Go ahead with the cut down ones or plug the old holes with a hardwood dowel (or even just bamboo skewers and Titebond glue) and re-drill.  Depends on how comfy you feel with the shorter shafts and how much work you want to go through:-)

    Speaking for myself, as long as the strings are already off I’d go with “plug and re-drill”.

    Have fun with your “new old harp”!

    Hi Sidney,
    That is fine in theory but make sure you have enough adjustment for the change in intonation that may come with fitting new semitones.

    regards
