Thanks Eric. The reason I thought about using the dowels is this will be a stiff handle bow. I figured with no movement there they would be OK. This is my first attemt at a recurve and this piece of wood was left over from another project. I was only going to shoot for about 40 pounds or so at about 24-26". The crack is pretty thin, but when I put it in the drying box at about 105 degrees, it opens up a bit more. I don't have any Urac so I will at least force in as much super glue as possible and clamp.
Again, thanks Eric.
