Here is my contribution to the glue issue.
I use either TiteBond II or Elmer's Carpenter's Glue for most of my balsa structures. I will use C/A for emergency repairs. I always use a "kicker" to set the C/A instantly, thus reducing exposure to the fumes. But, I use a dribble bottle to apply the kicker directly to the joint, never spray it. The kicker has it's own chemical exposures.
As for technique, most of my non-C/A glue joints are "double glued", one application to let the glue penetrate the wood and a second application, a fifteen to twenty seconds later, to stick it together. I use a Monoject #412 irrigation syringe, or precision oiler depending on where you buy it, to apply the glue. A pin in the end of the syringe will keep the glue from drying out for a couple of weeks. Wash the syringe with warm water every time you reload it.
I sometimes use the original Gorilla Glue for wet laminations. It is a urethane foam glue that is kicked off by moisture. The excess squeezed out of the joints turns to foam and is easily sanded off. Wear vinyl or nitrile gloves when using it.
White glues, like Elmer's regular, and the yellow carpenter's glues can be set, when you are in a hurry, in twenty minutes in a 200 degree (F) oven. Don't go over 212 degrees or the water in the glue will boil and blow the joints apart.
The yellow glues can also be set in a few seconds in a microwave, but home microwaves are not as well equipped or as precisely controllable as the furniture factory versions, as the photo shows, so I don't recommend it. (In this case I missed removing one, hidden, pin before attempting to accelerate the glue setting. Home microwaves don't have a metal detector.)
