Default RE: Three Real Basic Beginner Builder Questions

Like the guys said: you can use medium CA for most everything but it won't be easy to sand away excess so watch out if glue might get on an exposed surface. Epoxy is great for high-stress joints.

I'd like to put in a word for old-fashioned carpenter's glue - also known as aliphatic glue. I don't use it a lot but it is good stuff when you need working time. And, it is easy to wipe away excess, and to sand away dried excess. I like using it when making balsa plywood or when building up a layered surface to be carved and sanded down to shape afterwards.

I'd also like to comment on something in the original question:
...position, pin and then slop glue on joint?
Doubtless this was not meant literally, but even so it should be noted that "slopping" glue is not the way to build. Extra glue is just that - extra. Glue on the outside of a joint does little or nothing for strength, but it does add weight. Note that even though CA is applied to the outside of a joint, it works because it wicks into the spaces between the two pieces. A small fillet of hardened CA on top of the joint in an angled situation may be beneficial but "slopping" is to be avoided. And, as noted you can "harden" balsa with CA, but again there is "enough" and then there is "too much".

Yes, I know I'm being pedantic but I figure just in case. BHunn3 did say he (or she?) is a beginner...
