  1. Re: Wrapping strings around tuners too many times restringing?

    Ok, engineers and bystanders, this is the assignment. It’s a calculus problem. Assume the coefficient of friction is constant: maybe 0.2 for steel on steel. The initial tension is about 20 lbs. ...

    Re: Homemade Tuning Peg Tool

    Yes, you can easily break buttons and more. If you think of the post as a lever, with a gear on one end and a string pulling with about 20 lbs on the other, and the fulcrum being either or both the...

    Re: Oscar Schmidt Tremolina

    Sue, I’ve sometimes used repair kits for vinyl upholstery especially automotive. The kits contain little tubs of compound in colors and ‘graining papers’ which are fabrics imprinted with common...
  4. Re: Laberte et Magnié mandolin of uncertain vintage

    The mirror and strong light are needed in any event to check for loose braces before you tune the thing up. If you see the same grain pattern inside and out, especially contrasty areas, it isn’t...

  6. Re: Laberte et Magnié mandolin of uncertain vintage

    The French wrote the book on some aspects of modernism and Deco pretty early. The seminal Paris 1925 expo put things front and center. Even the stogy British, the same year, were aware of sea...
  7. Re: Help identifying a mandolin banjo / banjolin

    Agree entirely with RayT. The neck may even be a recent graft from a mandolin. If it is just screwed into the rim (screw heads inside, or maybe bolts) the skew may be adjusted without even using...

  9. Re: Dose anyone know anything about this mandolin or its value

    @ Mr. Bear et al: No, I think the OP could easily feel he’s been mocked. One can only take witty chances with those we know well. To the second point: I imagine he wasn’t keen to go back and check...

    Re: Wood Anatomy

    The OP is, perhaps, overthinking things. Much more likely in wooden instrument aging are more macroscopic effects like fracturing in glue joints and more mechanical damage to the wood itself. ...

    Re: mandolin wolf tone?

    An A on the E string also resonates the open A which can continue to sound its harmonic, so I hope you have a better example, or indicate that when you mute the E, you also mute all the strings.

    Re: High e-string keeps snapping, help?

    Why hasn’t anyone mentioned excess friction at the nut? The tension is always larger above the nut, and friction can be quite large. The shape, depth, and friction is not easy to measure,...
  14. Re: Gilchrist Using The Tone Traveler On Mike Compton's Mandolin

    Anyone want to either define, or start a very long thread about what warming up a mandolin means? I have the (moderately educated) feeling that, like many things in the present thread, that we could...

    Re: Post a picture of what's on your bench?

    I think the excess string has to exit the head to the sides for the kitten vibe; maybe about 4” each side.
    The tailpiece is nice, and novel. Are there grooves in the brass to keep the strings...

    Re: Bar Frets from Wiper Blades!

    This is a simulation, because it’s soft copper, but the same thing can be done with some of the harder materials. My turning rolls at home aren’t as clean or robust as the ones some jewelers have. ...

    Re: Oscar Schmidt Tremolina

    I may have the wrong concept, but I think you could widen the string spacing without grooving the bridge, if you just put spacers behind the top, that is, between the strings in a pair. As long as...
