The hole in the slot center is something I forgot to mention. I have been doing that for several years now and it works great.
I don't know the brand...... but I only use the CA hinges that have a small "slot" cut out, in the center of the hinge. This, in
addition to the 3/32nds hole in the balsa's slot center........allows the CA even MORE penatration. Like I said, never a CA hinge
failure!!........ lownslo
