  1. Re: Help me identify this bowlback please!

    Interesting idea, except that in the Italian style of building bowl back mandolins from the late 19th century the bowl and neck were made as a single unit. The bowl is built by one end of the ribs...

    Re: Sapele back plate thickness

    Sapele is not a commonly used wood for carved mandolins these days, though it was used earlier last century a lot more. Sapele is likely to be a bit lighter than maple so it might be better a little...

    Re: Fret Files and Other luthier tools?

    I was reminded by this discussion of the tool I first used for fret levelling and reprofiling close to 40 years ago. A plate of aluminium with two creases in it which was sold by the only place in...

    A new classical mandolin

    Just strung up this morning, a classical mandolin, for want of a better term. 13" scale, with a body inspired by a carved top Italian mandolin I found a photo of years ago. The soundboard is Sitka,...
  6. Re: Stew mac -- waverly f-style mandolin tuners

    Back in 2010 I visited the Waverly factory in Boseman MT and was able to watch as the base plates for mandolin tuners were machined out of a block of bronze by a CNC mill. A most impressive process...
  7. Re: Luthier for Fouchetti-period mandoline? Or Bortolazzi style?

    It might be worthwhile asking around the lute building community, but I can't think of anyone else who offers 18th century Neapolitan mandolins. I suspect the market is a micro-niche for such things...
  8. Re: Luthier for Fouchetti-period mandoline? Or Bortolazzi style?

    I take it that you are talking about early Neapolitan style mandolins as made by the Vinaccias, Fabricatore and others from 1760-1800 or so which used that stringing. If so, I would talk to Alfred...

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

    Pics of the two mandolins. The more guitar shaped instrument is the second of this design after I posted the first one a few weeks ago. This one is around 1/4" wider and longer and seems more in...

  12. Re: No mandolin content. Taylor Guitars story about sourcing wood

    What was curious is that I could not find any mention of what species of timber they were planning on using. I have no idea what has been planted as street trees in Southern California, other than...

    Re: String tension question

    Michael has kindly linked to the string tension calculator on my website, but it does have its limitations. As Bob A has mentioned tension is based on the mass of the string per unit length, but the...
  14. Re: Who was the first American mandolin manufacturer?

    Barry's point about a guittar not really being a mandolin is pertinent. I would argue that citterns (which is what a guittar is) diverged from what became mandolins two or three hundred years...

    Re: Guitar body octave bracing

    Looking forward to seeing some pics. Feel free to email if you have any other questions about the book.

    Cheers
  16. Re: Who was the first American mandolin manufacturer?

    My apologies Barry. I had forgotten that you had already suggested that important reference. I would think if anyone could give an expert opinion on the origin of the Davenport guittar it would be...
  17. Re: Who was the first American mandolin manufacturer?

    Having another look at the detailed pics of the guittar from Davenport, it looks very much like an instrument that came out of one of the guittar makers in Britain or the French makers acrossr the...

    Re: Guitar body octave bracing

    I like the X/lattice system as the lattice (for reasons I don't understand) gives a sharper attack to the note and a distinct separation between notes. It stops a pin-bridge guitar bodied bouzouki or...

    Re: corse spacing

    Forgive me working in millimetres but I find it easier. In general the width of the fretboard at the 12th fret is the same as (or very close to) the outside string spacing at the nut. For a 28mm nut...

    Re: Mandolinetto Build (Bracing?)

    I would suggest .120" for the soundboard and .080" for the sides and maybe a little thicker for the back. Any of your ideas for the soundboard bracing will work. Arch the braces to they are 1/8"...

    It seemed quite heavy so I thinned it to a bit more than I would for stiff sitka, getting close to 4mm/.160" in the centre with Sitka X braces at around a 80 angle that cross above the bridge and...
