    Re: Dry Bending Sides

    OFten some rippling is inevitable unless you have precise mould and counter piece that will "iron" the piece flat and keep it there till the bend is fixed. Tight bending strap helps, but the stresses...

    Re: Truss rod or not?

    Wood is wood and sometimes the nicest curly piece will be the unstable one that will bend under tension... It may make some customer of your best morel quite unhappy.

    Re: Next-generation Wood?

    That process is pretty much how some of the ebony substututes for fingerboards are made. You take some solid hardwood, dye, heat and compress it and you get stronger harder wood that works similarly...

    I haven't seen the Griffith Loar plans in person so I cannot comment on those. From detailed photos of that one I see that the top either has undergone quite a deformation or the arch was carver a...

    Re: Buzzing Single Open E String

    Hig fret would most likely cause both strings buzz (unless funky bend is involved at the fret ends). I would check nut slot first. Either entirely too deep or has ramp down towards board which causes...

    Re: Top and back graduations

    Sure the shape of arch and it's flow is one of the most important things. From my experience the beginning builders seem to suffer in both getting correct smooth arching shape and good graduations...

    Re: Top and back graduations
