Keep in mind also that both hinges flex easyer as time goes on. A happy median for you might be the flat Du-Bro hinges. They are flat plastic with a steel pin. The thiner wood wont be a problem with them and they will last the life of the plane. Also think about buying a Great Planes electric slotting tool. It's about $20 . Once you use one you wont know how you got by without it. later daveo
