    Aluminum tuner button question

    My current repair has aluminum tuner buttons on brass shafts. I have another antique that has aluminum on steel shaft. Seems to be common on antiques.
    I’m assuming that the buttons are cast...

    Re: Bowlback repair of missing back strip

    While you’re at it, and have that area open, it would be a good idea to have a careful look at the top, braces and all the joints from inside. Loose parts can sometimes be found by tapping on the...

    Re: Sprayed Glue?

    Any glue can be sprayed; even HHG. The plywood folks probably started that long ago; the auto industry uses robotic structural glue applications, so I can’t see any reason a high-volume instrument...

    Re: Bowlback repair of missing back strip

    Nice project for these doldrums. If you succeeded in an invisible repair including that crack, it would be something to brag about for several reasons, so the much more practical thing is to slice...
  5. Re: Semi-accoustic Mandolin build + various questions

    John, correct, and same for the other components, and sanding a bridge in place. So, the emergency home kit needs a fence. A couple inches of a 2x4 or 2x4 or some random container, held with the...

  7. Re: Semi-accoustic Mandolin build + various questions

    @JimCh. Interesting ideas, so not the usual acoustic-electric layout. Well, unless the bridge is sitting on that center beam, you still have to have a top that is thin, supporting the string...

    Re: Slot tuners Stiffness Problem

    Yes, those tuners look like brass or maybe bronze, but either way, they are more ‘lubricious’ than steel on steel, so that’s good. That is, they may not benefit from adding grease. The big...

    Re: Feedback: First fret pulling job

    I’ve never pulled a fret, but constantly am involved with non-destructively getting things unstuck. If the corrosion products are what’s ‘joined’ with the wood, how about some light lateral (that...
  10. Re: Considering applying a compound radius to my One And Only

    @sounds_good. I’ve used these things for wood and bondo (where they’re called ‘cheese graters’) and yes, very aggressive. I’d expect tear out at each fret slot. Plus, a 12” radius on a narrow thing...

    Re: "tinny" A string?

    Bernie, thanks for mentioning that; brings up something I noticed when looking at picks on Ebay. In some sets, for, I think banjo people, finger and thumb picks, but also finger tip protectors. ...

    Re: Figlio mandolin repair

    Frets, like everybody else, seem to have gotten taller and wider over the last century. Just checked my Oscar Schmidt (maybe 100 or so years old) and they’re even lower than JimCh’s, and very likely...

    Re: "tinny" A string?

    Mark, if you only get the effect when right on tune, and only the open string, I’d suspect a resonance. If it’s the same off-tune, more likely the detailed shape of the nut or saddle as has been...

    Re: Small rattle in soundboard...

    I remember being mystified (before Google) when reading Brit literature, like Dickens, where something called deal was disparaged about the same way we speak of particleboard. If you have scotch...

    Re: 50's Kay Jumbo Restoration

    May be called a “ribbed-neck bolt” or “knurled-neck bolt” You need the thread diameter, the head diameter and the length to specify. Should you bomb out, I think that you could get very close if you...

    Re: Fret Files and Other luthier tools?

    Here’s a selection of things that cut hard materials. The ‘electronics nibbler’ upper left, is generic and I just tested on 0.020 type 302 stainless sheet, no problems. However, it doesn’t...
  17. Re: Stew mac -- waverly f-style mandolin tuners

    One minute magic trick to reverse a tuner: loosen the string all the way, keep winding so it wraps around the post the other way. Done!
    Anyway, like the centipede who became immobilized by trying to...
  18. Re: Stew mac -- waverly f-style mandolin tuners

    I guess this has been beaten to death in the forums before, but since the Waverly design comes apart, worm over and under, even on an F can be just swapping the different length worm shafts - no? ...
  19. Re: Stew mac -- waverly f-style mandolin tuners

    On second thought, the older ones that are thicker, may have been cast. If the newer ones are milled from solid, the decoration, stamped or cut, would be shallow. I’m assuming that all of them are...
  20. Re: Stew mac -- waverly f-style mandolin tuners

    Could be anything, from die-stamp to CNC tool or photo lith. Actual hand-engraving would be silly in this or the last few centuries.

    Re: Fret Files and Other luthier tools?

    Well, the very expensive one uses diamond grit (300) so it cuts both directions, like sandpaper. The others are single-cut plain files. Everybody and their dog comes up with tool ideas. If I were...
  22. Re: Nitro as sealer on distressed build HELP!

    A spray coat of lacquer (from a gun, not a can), can be almost any thickness, so number of coats is meaningless. If the work is horizontal, for example, you can really put on a great deal. Choice...
  23. Re: Can I reuse strings I use for "in the white" stringup?

    I bought some violin strings. The key word for better is ‘synthetic’ as in the core is some fiber. They weren’t! The usage wasn’t important or critical, just getting strings on, but I tried them...
  24. Re: Can I reuse strings I use for "in the white" stringup?

    E- strings. I recently revived an ancient guitar-zither, mostly to put it on a wall. There are a lot of strings, with of course, the thin ones lasting least. On Ebay, I found sources of short rolls...

    Re: String angle over bridge

    John, correct, but I’d guess that anyone who hasn’t had a reason to think about it supposes that the bridge moves up and down, which is what Jim probably meant. Strings vibrate transversely, in any...
