  1. Re: How to lower action - old Gibson A1. Top or bottom of bridge?

    Just make a new replica bridge. Those old one-piece bridges are a simple design and not difficult to make. The most complicated part is fitting to the top of the mandolin and cutting the steps in the...

    Re: First repair - all advice welcome

    +1, and if I could "+" more than that I would.
    We need to know where we are going before we start. Plastic wood is almost always a no-no in instrument work.

    Clearer notes, better intonation, easier playing, better appearance, more work by the luthier.

  4. Re: Does changing tuning on a tenor require different saddle?

    Ha!
    I have a pretty good ear, but once in a while I have customers who can hear pitch variations of seemingly about 1 cent or less! Those folks can never feel like they are actually in tune, and it...
  5. Re: Does changing tuning on a tenor require different saddle?

    First of all, 'compensation' is a compromise. Tuning can never be perfect at every fret and every string (with standard frets). So, with that as background, going from CGDA (I assume you meant that...

    Re: First repair - all advice welcome

    First tip:
    Wait until you have the mandolin in your hands to decide what needs to be done and how to go about it.
    You can get plenty of advice here so feel free to ask nearly any question, but it...

    Re: Top and back graduations

    To me that all comes under "wood stiffness properties" as well as split resistance, stability and other things that were not specifically mentioned. If I have a piece of wood that is low density, low...

    Re: Fan-fret mandocello build

    The gist of what Dave found and I applied to my mandocello is this:
    The top and back plates of the Gibson design do not couple as well as they could with the air resonance because they are too small...
  9. Re: Nitrocellulose reactions with tuning machines

    I don't know...
    but it looks like something from the metal of the tuner has infiltrated the wood under the finish. I base that on the color looking to be in the wood under the finish, and it looks...

    Re: Top and back graduations

    Not really.



    A little bit. I feel that I have some control over sound, but once materials are chosen there are limits.



    Yes, but density figures into that with about as much importance.

    I've wondered if that is sometimes the problem people are having with shellac as a sealer, but I haven't mentioned it because it is just a guess and could easily be wrong. I spray only two light...

    Re: lacquer problem

    Ive never had a problem with shellac as a sealer, but I have with vinyl sealer. Any small sand-through in the lacquer at any time in the finish process leaves an area of clearer looking wood. Not...

    Re: $200 to dress mandolin frets? Ouch!

    You don't have to pay that much for fret work.
    As a repairman, if they can charge that much and get people to pay, more power to them!

    Re: Truss rod angle and depth

    The neutral axis of a neck turns out to be very close to the fingerboard glue joint. That is partly because the fingerboard material is generally a stiffer, more dense material than the neck. The...

    Re: Truss rod angle and depth

    This has been discussed here quite a bit, and it can get pretty involved. This applies to "standard" tension truss rods. Two way rods, stiffeners such as CF rods and so forth, those are different....

    Do as Earl said, but if it turns out that the zero fret is too low, understand that zero frets wear and must be replaced occasionally.
