Well, I am planning on doing a kit bash, more on that later, and had a small amount of 1/8" balsa 4" wide sheet that is just enough for one fin so I needed to get some more. I went to my local craft/hobby store, but they did not have much selection to match the leftover 1/8" balsa that I had. I did not want to get thinner stuff and laminate them myself, so I went ahead and got some 1/8" birch ply. These sheets seem plenty stiff, my fin design will be swept and extend aft so they will have to survive ground impact on landing. I probably won't paper them, just use sanding sealer and lightly round the fin edges just to take the sharp corners off. Oh, and I will have to fill two of the fin slots and make three more, going to turn this into a 4 fin model. Will have to deal with the pre-notched centering rings also.
I also found some LOCTITE brand "instant" epoxy that comes with in a double-chamber syringe with a self-mixing funnel tip, but the tubes were in a pretty small quantity 0.14oz. I may give that a try, after I do some test parts on scrap first to see how well it works.
Potentially a confusing part of the instructions is that they show an image of a single bottle for the recommended epoxy, but epoxy is usually a two part mixture, right?
I might end up cardstock papering these with wood glue, the stickers they put on them with the price tag do not come off in one piece and leave a lot of traces of sticker paper behind. I will end up sanding them down first and not sure how much material that will remove.
