haha classic comments Barge, I know the feeling waiting for a kit that you can't wait for !
Hopefully tomoz Barge. Have you got the flame maple cap ? You should be able to cut out the shape very carefully with a sharp blade I reckon, then sand it when it gets close to the cavity edges. I glued a veneer to a uke kit and had to cut out the soundhole and managed to carefully do it and sand near the edges
