Terry, Greg, et al,

Titebond II works quite well for soundboard assembly. It has a good working
life, it is nearly waterproof and dries/cures to a rigid enough bond that it
can be used for most bent-laminate purposes.

I'm curious, however, why you would seem to think 'glass-like hardness'
would be advantageous for either soundboard assembly or installation.
Neither the spruce used to make the soundboard panel nor the maple (or
Select Hardwood) rims the soundboard is glued to is glass-like hard. Nor are
they particularly rigid.

If you'd like to get more sophisticated in your selection of adhesives--and
if you're willing to purchase them in 1-gallon and 5-gallon quantities--you
can get MPA II from CustomPak. (See www.custompak.com. Their site lists
mostly 1-gallon quantities, call them, 800.454.4583, for 5-gallon prices and
more information.) This is simply a commercial version of Titebond II (made
by Borden [sp?]). It is white and cures to a milky, translucent color.

You can also purchase (from CustomPak) MPAs in variety of other
formulations; high viscosity, low viscosity, heat setting, etc.
