Why would you use multiple layers? If the joint is tight balsa then thin is all you need, balsa joints that are not tight and all lite ply joints need the thick gap filling. Once the joint is glued extra applications of more glue in most cases is just adding weight.

Thx for the answer - case closed. Oh yea - the kit instructions of my current build state to use multiple viscosities however they don't state 1 before the other.

Jim, it's either or. They call it gap filling but just filling a gap with glue isn't doing a lot. If you do have a gap like between a rib and leading edge cut ans sand some balsa, put it in the gap for a tight fit then hit it with thin CA. That's wood on wood and makes a strong joint. Ca also doesn't like to stick to dry CA.

What Grey Beard said. From Grey Hair (what there is left of it:-))))))). It depends on the joint you are making, what viscosity of CA you use, and CA does NOT stick well to itself.

The last time I layered glue to itself I suppose is when we had to preglue all the major joints with multiple applications before assembly when using wood cellulose glues like: Testor's, Ambroid or UHU Hart. He, he I through that last one in for you Jaka

I never had any luck with the thick CA's for some reason. I use the thin, the alihpatics and epoxy.

when I am building a balsa stick fuse on a board, then I use thin CA and glue the entire side together. After I remove the fuse sides from the building board and spline sand both sides of the each fuse half; I always go back and use a single drop of medium CA in every corner of the verticals and diagnals. I generally don't design my fuse structures with sheeting because there is just too much weight in sheeting and glue, and its just not needed. On my motor boxes I always use 3/32" bass plywood with balsa medium density tri stock in all corners, I first thin CA glue all the plywood components together, then I use medium CA and glue in all the tri stock followed by sweating in thin CA at every corner until it does not take anymore without pooling. This works very good on giant models, I would think it would work just as well on the smaller stuff.
