Glue for laminating a bentside

[Eric Wolfley]

Ed,

I've laminated a number of bentsides using West System Epoxy (slow cure).
It has shown absolutely no signs of creep or failure of any kind. I like it
because it will fill any gaps that might occurr. The urea-formaldyhyde glue
will work fine also as long as there are no gaps. I believe most piano
manufacturers use this glue for their rim laminating. Hide glue has a
historically proven track record as well. Tightbond or other yellow glues
are not recommended because they will creep.
