Re: Almost consistently bad glue joints...

It had been 2 or 3 years. I offered to fix it for him. Its certainly possible it could have taken some knocks, life happens. Also possible my technique wasn't perfect. I do like the idea of the glue being bad. Left in a cold basement shop for who knows how long. It was a gallon size bottle.

Re: Sound hole placement...

Wow, thanks guys! I didn't expect so much info/tips, but am happy to get them. The elf shortage is due, I'm sure, to covid. The ported sound hole sounds intriguing. At the end of this one I may look into it. It sounds REALLY intriguing! This baritone is a little over 16" at the lower bout, and ...

Re: Sound hole placement...

I think i understand what you're saying. Ill use a j200 for reference in size and placement, so as to not deviate from what works. Thank you for all the tips and comments

Re: Almost consistently bad glue joints...

I have a radius sanding block that I use to radius my fretboard as well as clamping. That goes on top of fretboard. Should I be using something under the clamps on bottom, too? Like a 2x4?
I appreciate your help, thank you

Re: Sound hole placement...

Hmmm... I know that when tuning a port on a speaker box. You pull the tube out until you're happy with the sound, and cut it there. Aside from cutting a small hole, stringing the guitar up, playing it, then unstringing it, enlarging hole, re-stringing etc until it sounds good, is there a way to form...

Re: Almost consistently bad glue joints...

I've cleaned up the neck and bottom of fretboard, taking care of all the gouges, nicks, and low spots. I've verified that both surfaces are indeed flat, and that the Truss rod sits just below the necks gluing surface. So I'm ready on that front. Does gluing together two different types of wood promo...

Re: Almost consistently bad glue joints...

The gouges and nicks came from popping the fretboard off. I've since purchased 12 clamps, I hope that will be enough

Re: Almost consistently bad glue joints...

The glue wasn't stringy or watery. Freshly planed tone bar bottoms? Ok, got it. How about the underside of the soundboard? Planed? Sanded?

Sound hole placement...

Hey guys, just wondering if there is a formula for placing sound hole, maybe it has to do with the scale length, or maybe nodes, like pickup placement? Also, since we're on the topic, sound hole size. Is that figured by volume of guitar body? Or maybe thickness of top?
