One of the few benefits of getting old is you don't care how stupid you look, so here goes.
When I quit building everything was glued with Amberoid. Epoxies were just coming in. Now I see that most every think seems to be glued with CA. I see where there is thin. medium, and thick. They also have accelerator. Since I have never used any of these in new model construction I don't have a clue which one to use where, Do you assemble something like a wing and then just put a drop of CA on the joint and it will penetrate? Which Ca? Does the accelerator weaken the glue? Should the joints be "push tight" or should the have a little clearance for the glue to penetrate. Is there much difference in the brands of CA? I have a pretty good handle on using carpenter type glues for laminating and that type of thing, but I see some people use it for the wing structure. Will it penetrate the joint or do you have to apply it to the pieces (s) before you assemble them. I think I understand where and how to use epoxy.As you can see I am all questions and no answers. Please help the elderly.
