A long time ago when building a KR-1, together with two good friends (Homero
Brandão and Matheus Abram), we did a big amount of tests regarding glued joints
using epoxi resin (in our case case Araldite - TM from Ciba Geigy).
>From tests we learned the best way to glue wood:
Glue surfaces cleaned an as smoth as possible ( never glue
rough surfaces)
Soak the resin so as to obtain the best impregnation in between
the fibers of the wood
Do not put too much clamp pressure to avoid the ejection of
all resin between the surfaces to be glued. We must have
a film of resin between the surfaces.
Never put more hardener than recomended for the mixing ratio:
Hardener in excess wil not permit the right cure and re-
sults in a kind of "rubbery resin" , very weak. For your
information, normal epoxies will have full strenght after 72
hours of cure.
Avoid to glue during days with high degree of humidity.
Regards for all,
