I'm curious to know what adhesives people here use when they need to bond wood for their CBGs. I've tended to use various epoxy glues which have been fine, but I'm beginning to wonder if other adhesives have any advantages. I've used cascamite for other types of wood working and I'm aware of at least one instrument builder who uses it.
(I thought I'd ask the question here within the British section because discussions in general forums about materials and techniques tend to end up with people suggesting American brand names, which aren't much use to me)

I use titebond for everything, not had any problems with it thus far - certainly seems very strong. It comes highly recommend in the ukulele luthier community.
Evo Stik green, same as Paul ... you'll destroy the wood before you break the glue-joint.
There's a 'blue' one, which I believe is a waterproof version, but since there won't be much left of a cigar box outside in our weather, the green bottle does just fine. :-))
Sorry I missed your reply somehow - I have fallen out with Gorilla Glue too many necks have ended up off centre despite best efforts with clamps! - will probably go back to resin even though it is tricky to undo if needed!

I think titebound does something like the tradional glues you mention, although ive not used it. Think i saw it on the touchstone tonewood site.

Dont even think of using gorilla glue or so many other whizbang happy homemaker do-all adhesives! The soft glue will dampen sound. an expanding glue will push tight joints apart.
Traditionalist use a glue made from boiled hide and hoof, horn will also work. A modern inexpesive way to go is to use gelatin powder in warm water.
I use carpenters yellow glue---dries fast but not too fast, is cleanable with water on a towel, can be hot knifed apart if I make a mistake, shrinks dry, stronger than wood, and very important, it PENETRATES the wood so it really really holds.
No need for high tech glues or wonder wizard materials here, people have been making instruments for thousands of years, and they all did just fine without high tech, so drop the Dupont products and see what you have in the kitchen! Ever boiled sticky rice into a glue? It has worked in asia for thousands of years...and its acid free, so you can mount art prints with it too! High gluten flour paste has been used in the west...
You can even make your own varnishes of shrimp shells....
No end to what a creative person can do once they get outside of the mall again!
I have been a carpenter/furniture maker for twenty years and have tried a lot of trendy glues and potions and I always come back to evostick pva if you use the interior stuff in the green bottle you can undo it with a little water and some care. If you know it is not stuck upside down / inside out / back to front etc etc use exterior grade in the blue bottle. -If you cock that up - thats the way it stays I'm afraid. Titebond make a liquid hide glue or you can go down the pearl glue which needs to be melted in a double glue pot, both are reversable with heat. Traditional hide glues ie Rabbit skin or fish skin glues are easliy reversed with water and a little heat but in an english climate that can be a problem (the water part not the heat). Best results for piezos so far is a rubber compound called CT1 it bonds most substances wet or dry metal, wood in fact anything to anything so long as it's not powdery or loose and weirdly has vibration dampening qualities. www.ct1ltd.com

Hi - I just bought some Gorilla Glue - I usually use resin but saw your comment a few days ago - have you ever tried it to attach metal to wood? It says it does the job but both my tests have failed so far. Only trying to attach a magnetic door catch on a CBG where the lid is too thin to screw the plate on. Any tips?

My personal favourite is standard Gorilla Glue - It is an expanding glue so it is great for joints that you have not cut as tight as you would like . I pretty much use it for everything

You make a Great point, I'll use the carpenters glue on my next build!>Perfesser Blue said:

Yup, I've already ruled out polyurethanes (eg. Gorilla glue) or PVA, on the grounds you've mentioned. I'm looking for something more along the lines of traditional glues in terms of the hardness, strength and "wood friendliness" properties - but ideally without the faffing around that would be entailed in boiling stuff up from "raw" ingredients.
Can you tell me what carpenters' yellow glue is? It sounds a little like cascamite in some respects - which I believe is a urea formaldehyde resin.

Order there catalogue for hours of bed/bog reading.
Hope this helps.
