I have been scratch building race planes for more decades than I care to admit. I use thin and medium ca for all balsa joints and epoxy for all hardwood. I use only laminating resin and not garbage minute resins. A special note here, West Systems resin is a marine resin and not a laminating resin and should never be used as such. The makers of West resin make a true laminating resin (Pro Set) that is a vary high quality resin. West 105 is probably the worst choice one could make when one needs a laminating resin, but one of the best marine resins available if you require repairs of your boat.
