Another way to scarf

Ran across this from the "other" boat forum, thought some might be interested in the jigs and in panel orientation discussion

Always looking for information and better ways to do things when we build our boats.

I have found a scarf joint is not hard to do in regular plywood. I use a jig for my circular saw like the one in the link. Scarfing luan has not worked for well for me. I can make a strong joint, but a clean look, and fit has been impossable. The paper thin outer layers are too fragile. If the ends are not a perfect match (flush) the outer layer will get sanded away. Just sanding the glue run out will damage it. Not a problem if painted over, but ugly if a natural finish is used. Butt joints are about as visable.
I have not tried this, but a combination scarf and but joint may produce a less obvious looking joint. Cut the ends on slight oposite angles, and butt together for a tight and level fit. Then back the joint with fiberglass.
