    Re: Boomerang Banjo Mandolin

    A standard bit of kit I've found in many old banjo cases from the first half of the 20th Century is a tan art-gum eraser. That seems to have been the tool of choice for cleaning a calfskin head, and...
  2. Re: Is The Note On The 5th Fret Of Your Mando’s “A” String a “D”?

    If fretted notes are most sharp at the low frets but get closer in-tune as you move up to the 12th fret, the culprit is the height at the nut. As you push the strings down to contact the fret you are...

    Re: Is this a serious concern?

    Necks are not glued to metal bodied instruments. At some point the neck began to pull forward and someone smooshed some kind of glue in there. It did no good, of course. It would not be very...

    Re: Unique Ball End to Loop End conversion

    IIRC we had a similar problem with stringing our Hofner 500/1. Pyramid strings were the only ones we found that didn't have a wrap that stuck out past the nut.

    Re: Unique Ball End to Loop End conversion

    I think mdowlin is right. From the thread wrap those look like they may be Thomastiks, which would also have a wrap over the other end of the wound strings. That might have stuck over the nut without...

    Re: fret marker positions

    Five string banjos from the 19th Century typically have markers at 5, 7, 9, and 12. Tenor banjos, which surged in popularity in the 1920s, 30s, and 40s, have them at 5, 7, 10, and 12 [Tenors are also...

    Re: Use of Oak in instruments?

    My old store had a couple of early 20th Century oak guitars. I remember one was a Harwood; pretty good sounding parlor size instrument. Oak just looks weird, though; you kind of expect it to have...

    Re: Best way to fix this bowed neck?

    You need a shorter straightedge that stops before the kink at the heel to see if there's really a bow in the neck or if the real problem is at the joint. You will likely need to remove the...

    Re: Finish delaminating National RM-1

    Dan, you need to call National Resophonic and see if you can email them some photos. Don't put anything like wax on it.
    I suspect moisture has migrated into the bottom of the case. That would also...

    Re: Resting a Kay "Lyre" Guitar

    No shim; you want to support the original arch of the top. How hard is it to press the brace and top together?
    With the top as it is would you need a stupidly tall bridge?

    Re: Question about CA glue

    The current KM500 claims to be nitrocellulose; older ones might have a synthetic catalyzed finish. The only way to tell for sure is to test an area with acetone. I pull off one side of tuners and...

    Re: Question about CA glue

    What brand mandolin? If it has a poly finish you can use solvents that eat nitrocellulose lacquer.
  13. Re: how to rip binding strips from celluloid sheet stock

    I use a strip cutter from MicroMark, their number 14568. It uses x-acto blades, and has a micrometer type screw to set the width of strip. I set the blade so it makes a deep score in the binding...

    Earthwood mandola? I'm afraid you'll have to post photos. Even a GIS turns up nothing. Glued bridge?

    Re: Catalyzed Varnish Repair

    A repair on a catalyzed finish will always show a "witness line" where the new finish meets the original finish. A drop-fill with CA glue [superglue] sanded and buffed can be very inconspicuous. If...

    Re: Guess the finish

    First, I'd be surprised if the back wasn't made from staves, rather than a hollowed out chunk of wood. But without any photo that's just conjecture.
    To determine the finish, test an area [perhaps...

    Re: How to polish metal parts on mandolin.

    No, chrome plating would not have been used on an instrument of that vintage. It's nickel plating over brass, which is easy to engrave. Avoid liquid or paste polishes because they are going to leave...
  22. Re: what glue to use on 70yo mando w/ previous repairs?

    Or perhaps older. We still haven't seen a photo... and no information about the previous repairs. So this is speculation of practically no value.
  23. Re: Anyone know what the old flatirons were finished with?

    CA might be the best thing for you to use anyway, but the typical way to test the finish is to remove a tuner and dab an acetone-dampened swab in the footprint. A cross-linked finish won't be...

    Re: Ups insurance a ripoff

    Well, only true if the box falls on its back. If it falls forward [just as likely] the string tension is pulling in the direction of the shock. It's a crap-shoot.
