I have 50 years of woodworking experience and have always been less than
pleased with Resorcinal glues. If it's not clamping pressure then it is
consistency, working time, shop temperature, shelf life, etc.,etc. It is not
a forgiving glue. Alternatives...??? T-88..??? difficult to do larges
assemblies, good gap filler but if its filling a gap you have a bad
(brittle) joint, also need more than moderate clamping pressure. What ever
happened to that 2-part glue that came with the KR kit years ago? I believe
it was called aerolite. That glue was easy to work with and reliable. I made
several violins and mandolins with that stuff and it holds up wonderfully.
Of course these instruments were not subjected to extreme temperatures and
humidities. I have a lot of faith in Titebonds exterior glue but have not
used it in aircraft structural partsbut I have more trust in it than in
resorcinol I have used West System epoxy as both a laminating glue and
fiberglass wetting agent and find it exceptionally reliable and easy to work
with. What is everyone else using out there.?
