RE: Glueing Balsa, CA or Wood Glue?
Over the years , I've lost my tolerance for CA fumes. I went back to Tite Bond II and it is really very good. I recently picked up a 40 Super Sportster in a trade and was amazed at how much thick CA there was smeared all ove the inside of the thing. The main rule is that if a little glue is good, a ****load is not great.
The thin CA works great on tight fitting balsa joints. The medium is nice for not-so-tight joints. Putting wood glue on top if CA doesn't make any sense to me. I fit everything well, pre-glue my end grain, and am very happy with the Tite Bond. BTW, CA does not evaporate, so weight builds up fast if you don't pay attention.
One of the best custom builders I know buys regular Elmer's white glue by the gallon and uses only it with the exception of some epoxy.
