  1. Re: Teensie-Weensie little position markers

    Endmills and similar centerless bits will walk unless you are set up in a rigid machine, like a small mill, but will make a clean hole. Plain twist drills (59 degree) will stay centered, but will...

    Re: Virzi tone producer

    Some might think scrolls on mandolins, violins, cellos and basses are just visual punctuation, but recently found documents show that a fellow named N. Tesla suggested scrolls for that odd location...

    Re: Virzi tone producer

    Thanks, but if that’s all they did, the same effect would result from just sticking some mass on the top at the same attachment points. Pretty clear that these things change possible cavity...

    Re: Virzi tone producer

    These things relate to the cones in steel resonator guitars somehow?

    Re: Is it defective ?

    Skanda, you obviously knew about bridge fore-and-aft placement, when you took it to the shop, and the person there probably did too. Maybe what they meant was that the bridge height also was too...

    Re: 7th fret problem

    There’s a good Wikipedia entry “inharmonicity” that might relate. My take is that the spectrum generated by two different length, mass, plucked strings is different, even if the fundamental (what...

    Re: Screws for tuner buttons

    In my Brit car restoration days, the five different thread types engendered great amusement, including learning that even metric varies with origin. Then, the watch and clock makers seemed to have...

    Re: torrified wood woes

    A reminder of what happened when actual research into cryogenic effects on various materials blossomed into all sorts of, dare we say, hucksterish opportunities and fads, primarily affecting the...

    Re: torrified wood woes

    Science guy, non-builder here. There is actual literature on the subject; see, for example, Annals of Forest Science, 64, 679 (2007), because the process (really many processes) are used for other...

    Re: Saddle Fail

    As noted, it’s a piece of wood. Worse, supported only at the ends. Worse still, pretty minimal. All to make it adjustable. One of the reasons we don’t make too many planes out of wood anymore. ...

    Re: New OM build maple neck questions

    Every tree, like us, is a little different. Chances are, you’re fine with something as small as a neck, but if you bookmatch, or mirror, the two outer laminations, you might be a little safer. ...

    Re: Rogue A Style Tuner Upgrade

    I just bought an ultra cheap set on ebay for a similar cheap repair, and despite the supplied drawing, which showed the common 23mm spacing, it actually was 25.4 or 1”. No idea what that’s supposed...

    Re: inlay replacement problem

    Such a difference between the skilled craft world and everything else, where it is always possible to blame somebody else for one’s mistakes! Hasn’t worked that well lately at Boeing.

    Re: Reducing chrome Grover F tuner shine.

    I have a ‘micro’ sandblast that uses very fine abrasive that is used to clean small parts, mostly. It will make a very fine matt finish on most things, without resorting to chemistry. A jeweler...

    Overclocking a chip, over-revving a B&S and over-thinning a mandolin all may have similar results! Without instrumentation or experience, might one go the other way and stick little weights on the...

    Re: Another carbon fiber question

    Again, not as a builder but more on the engineering side, if the truss rod is only set to operate in tension, it must apply force behind the neutral plane, that is, at the back of the neck. If,...

    This effect may be epidemic, requires serious study. We do have to be careful, though, as it may edge into very dangerous territory.

    Re: ToneGuard Question

    Yeah, well, when the lady (or man) you’ve been with for 30 years tells her friends you play the banjo-something, you have a reference point.

    Another issue. Although I’ve only had a couple of mandolins, and don’t see repair work, my ancient 12 string bowlback had a problem related to either materials or skimpy design. The gear wheels are...

    Re: filling fret wear

    Ok, I do know more about solders than frets. As a rule, solders/brazes that are as hard as frets are high temperature ones, and as far as I know, fretboards are made of wood, which isn’t. To get any...

    Re: Tuner adjustments

    One reason worm and gear mechanisms are used is that they are highly resistant to being moved by torque at the gear side, so instrument tuners, which are crude, low-precision devices, generally hold...

    Two different functions. A reinforcement makes the neck more resistant to warping over time. It is in contact at all points. A truss rod as usually described is free to move in the neck and is used...
