I agree with bedding the beam with epoxy. However I would add microlight filler or finely chopped figerglass so all the epoxy does not run out and instead of waxing the beams, use 2 layers of wax paper or mold release film or even plastic wrap. It will be a lot easier to remove 2 years from now.

One of the reason pure epoxy is used for this is, it is not a very good glue. It does not stick very well so a waxed beam is good enough. Also it can run and leave voids. If you have some kevlar cloth, cut some up very fine and mix it in. It will turn into a gel that looks like something a cat would cough up. A small amount gives you a yellow gel. The more you add the more it looks like a yellow furball. You want it to look like room temp jello.
