    Re: V joint question

    That joint has big advantage that you can machine it precisely and consistently, but the strength fully relies on the glue only. The tapered dovetail (when correctly fitted) is self tightening and...

    Re: Gibson F-9 repair project

    But don§t remove anz wood from the shoulders of the joint, just flatten the inside surfaces of dovetail and add thin veneer shims and rework them till the neck fits in snugly against body with...

    Re: Gibson F-9 repair project

    Similar to what I found inside F-9 joint, in my case there wa also filler, added after gluing to fill the gaps left mostly on the scroll side. The brownish hardly translucent finish hides all that...
  4. Re: Confused about a spirit varnish over a sunburst on first mand

    Personally I airbrush almost dry layer of sheallac to seal the color and then brush 3-5 layers of oil varnish (currently this one :https://www.ceneo.pl/8297358 - simiar to old style phenolic...

    Re: fretboard support opinion?

    I don't see any problem in that original joint, the riser block with crosspiece is glued to body block solidly and also butted against top edge of top plate so there is solid anchor for pressure of...
  6. Re: Confused about a spirit varnish over a sunburst on first mand

    Bill Halsey studied the finishes on his collection of teens and early 20's Gibsons a nd came to conclusion that they used oil varnish base (judging by typical features of slow drying finishes like...
  7. Re: Confused about a spirit varnish over a sunburst on first mand

    I tend to believe that old Gibsons used oil varnish instead of spirit/shellac right over the dye as it disturbed color the least, applied few coats of oil to seal color and create good base and then...

    Re: Gibson F-9 repair project

    I would stay away from back removal as well, unless the seam between ribs and back is compromised. That would lead to mess of a finish chips and no way to repair the finish.
    Trying to wiggle the...

    Re: fretboard support opinion?

    The shape doesn't have to copy shape of fretboard as closely, Loars usually had just king of tongue 1/4" or so shorter than fretboard without the point. Often without too much rounding, just chamfer...

    Re: Gibson F-9 repair project

    Form the (rather blurry) pics I think the joint MAY be loose near the bottom of the dovetail. There ceratinly appears to be a gap between ribs and heel of neck and I see ahint of tiny crack in rib,...

    Re: Neck fall away at 12th fret HELP?

    How does the underside of fingerboard look like? Is it flat or is the angle already in there? What type of mandolin are we talking about?
    The only instruments that may need the fall off are acoustic...

    It's too late now but by cutting it away you probably lost the easiest and strongest possibility of rebuilding the tenon... but pics would help alot to judge the situation...
  13. Re: Gibson threatening the mandolin and guitar luthier community

    I have seen and deeply studied my share of these scrolls and made comparisons in computer and they ALL are based upon one design albeit not always executed with perfect precision. The flow of curves...

    I never suggested Loar really worked on these mandolin nor designed them. I guess he didn't do much more work on instruments other than...
  15. Re: tinting white binding on a french polish instrument

    Many companies name the batches themselves so names are not equal among sellers. Basicly anything darker than bleached water clear shellac will have some color. The lightest is usually called blonde...

    Not exactly to OP but...
    I don't know privileges but they certainly build to specs that their CNC staff loaded into machines. I'm not talking about sound as I haven't played recent Gibson (post...
  17. Re: tinting white binding on a french polish instrument

    Unless you will use bleached shellac, the FP will add slightly amber tone to the bindings. You can spray some thin coats of shellac (amber or darker) as sealer on whole mandolin before french...

    Re: Minimum saddle height?

    I would just plane top 1/16" off the saddle and glue (with CA) one long strip of new ebony and reshape to match the shape of compensations (any small remnants of slots would be filled by CA glue when...

    Well, from what I've read, folks are sometimes suing companies for much more stupid reasons. (Not that I agree with all that suing) Smell of money is really good enough reason for some. :-)

    Re: The real glue strength

    Is the TBLHG soft and rubbery inside the joint or the squeeze out? You should remove excessive squeeze out glue right after clamping with stiff brush or spatula. Large bead of wet glue sitting...
  23. Re: Gibson threatening the mandolin and guitar luthier community

    Perhaps modern Gibsons have smoother surface because of heavy use of sanders and thick layers of finish but Loars had that specific crisp style even if some roughness was present. Of course there are...

    Re: Fretboard Riser

    That is what I aim at too. I would add that I fit the neck before I finish shaping of the riser. I aim for 1/2" overstand at the crosspiece and neck projection (with starightedge placed on surface of...
