Re: First commission

Make sure that they understand that you will 'take your time' to make sure it is a hand built and hand tuned instrument. The hardest thing I find with pre paid builds is the expectation and the pressure to finish the job...I have always stood up for doing my best rather than being pressured time wis...

Re: Back burner jobs

I have the remains of a 1970's Martin neck hanging in my shed. The guitar it was once attached to was removed by him being hit over the head by it during a "domestic dispute". I like to think that he was standing up for the rights of instrumental noodlers the world over...but it still might have bee...

Re: Back burner jobs

I had to rebuild a similar Martin which had similar injuries. I opted to rebuild with new back and sides upgrading from the original mahogany to Indian rosewood, keeping the soundboard and neck. The client was happy with this approach. The result was a much better sounding guitar than it was origina...

Re: Reducing x-brace angle?

I forgot to mention above that arching a soundboard effects sustain, top resonance and projection. Confused? So am I. That is why, as well as knowing a bit of "left brain" luthierie, experience is also important, and so is tradition. Look at violins...they evolved over generations on a largely exper...

Re: Reducing x-brace angle?

If the brace angle varies it either closes or opens the area where the braces can sit on the tail end side of the soundhole. This has an effect on the area of the soundboard that is available for low frequency response. It also can allow for forward shifting of the X brace junction which also effect...

Re: Reliable Hygrometer Calibration for the Luthier

The laminated veneer hygrometer is not very accurate and should really be taken as an indicator. It is quite possible to just seal one side of a single veneer to make one as well. But this is a great demonstration of some of the issues surrounding guitar construction and stability. I have double gla...

Ive found the quality of the Selly's and other quick epoxies not that great and if you need to do any unplanned adjustments you might find yourself in a bind.

Good idea. I would like to see a photo of the finished guitar sometime down the track.

Then I use hot hide glue to g...

Re: Maple side crack, any suggestion ?

I once tried as an experiment, to repair a similar split with superglue then continue bending, but the fumes are horrible when hand bending ...

And my finish ends up being 1/2 the thickness of what I had using lacquer. So does this imply that it is in fact a thinner lighter finish than shellac and nitrocellulose? Also how about finish repairs eg drop filling and levelling, also colour matching with both dyes and pigments? How does it react...

Re: How to UV Finish

Thanks Steve.....out of my price range. Think I'll stick with the French Polishing :mrgreen:
Shellac is non toxic and doesn't support the oil, plastic and chemical industries. Its also a much finer lighter finish for soundboards, as we all know and easily repaired to boot. -Ross

I have tried all sorts of laminating methods and glues. The water based glues, eg Hot Hide Glue, do not set in a vacuum.
