Another idea that I read about here and have used is to stretch plastic wrap (seran etc) as tightly as you can around the half of the stab that will go through the opening. Use tape to hold it along the edge of the stab covering (next to the exposed balsa). Goop up the saddle and the exposed balsa on the stab. Slide it through and then remove the plastic wrap before the epoxy sets up. Works really slick. When you stretch it it gets REALLY thin and have yet to have it bind up as it goes through the opening.

Am interested in the CA idea too. That sounds really easy.
