Does anyone know where I can buy casein glue, hide glue, or some

Hide glue isn't waterproof. That's actually an advatage sometimes.
You can take apart the chair, or whatever, and reglue it.

BTW, I mean the sort of hide glue wher you mix pellets with water in a
little cooker and then apply with a brush hot.

Yes, I remember that from when I restored an old lute once.
A little research now suggests that casein glue is rather more
resistant to damp. But so far I have not been able to find any of the
natural stuff. All I have found is a synthetic version. I'm wondering
if I can simply use casein protein powder from a sports nutrition
outlet.


Use cascamite. It IS fairly wet proof. Not totally though.

I think the standard aircraft glue was Aerolite 306..a urea formaldehyde
type glue IIRC.

You painted one bit of wood with formic acid and the other with
something made out of a powder paste. Set rock hard.

Theser glues were almost totally replaced by PVA and epoxy/synthetic
resins repsectively..for non waterproof/waterproof applications.

Now I am prepared to admit that the acoustic properties of modern glues
may be subtly different, but as far as structural properties go, the old
'natural' glues were more or less *rubbish*.
