Re: Intonation and Hand position

I just had a close look at this on a classical guitar with the T(1,1) at 100Hz and the T(1,1)2 at 191Hz. The guitar was perfectly tuned on the open strings and played G in tune (according to my Korg CA-1 chromatic tuner) when I plucked the G (3rd fret 6th string) in a fairly normal position. I moved...

Re: Falcate braced classical

That's what the small diagonal tertiary brace in the lower bout is for...and is currently missing from your design. A couple of diagonal grained diamond cleats will do the job if you don't fancy a brace there.

Re: resonant frequencies no where to go

Pretty much what Luke said. Try to keep the bridge mass lower. It's possible to get down to 14grm for the bridge (no pins/saddle). Finish the build, and if you find a problem you can hear with the main air resonance consider enlarging the soundhole, but you can always come back and seek more advice ...

Re: Compensating?

Possibly! The compensation techniques I use focus on getting the fundamentals of each note to play in tune. However, string partials always play sharp with respect to the fundamental to some degree (on steel strings generally not much), so stretch tuning (which is what Taylor is doing) is not a bad ...

Martin,

Not sure whether you've just not got round to it yet, but filling the gap between the neck block and the UTB is always a good idea.

Re: Gibson Kasha disaster

Assuming nothing has actually let go on the inside.... ...you could try one of those bridge doctor thingies, and jack the top more-or-less straight (over a few weeks). Given that the sound couldn't get much worse (no sound!), it's not a big risk or a big expense. The neck twist is another matter. It...

Re: Seperate PU-glued joint with heat, solvent or saw?

Funny (as in strange). I've just had a PU joint fail in a non-guitar related project. It's not like I don't know how to make a joint! I thought this stuff was supposed to be idiot proof! I did some rough-and-ready testing (butt jointing 18mm ply) and disassembly with a mallet. I'm back to using Tite...

Re: Angle SIdes - 15" Back on Weissendborn

A dome is a dome is dome. Which is the great thing about domes. So as I see it (I hope I'm understanding this) you have two options: 1) Dome the rims over their whole length (butt to headstock) with the high point of the dome towards the top of the upper bout. This will, of course, narrow the depth ...
