I am NOT visualizing this setup. Are you drilling the holes in the plane itself or the blade? I think where you lost me is on the groove for the plane blade. Does anyone know of a drawing or picture that could help me out here?

: I put a 45-degree bevel on some of the Okoume panels on my Pygmy. I bought a
: Stanley block plane for about $20 at Home Depot. Any brand of block plane
: will work as long as it DOESN’T have an adjustable throat. Drill a
: 3/16-inch hole in each of the four corners of the base. Then get a chunk
: of 2 X 4 and cut one edge at 45 degrees. On that slanted surface, cut a
: groove for the plane blade. Now screw the wood to the plane. You will hold
: the wood block against the wood panel as you plane. You will have to
: unsrew and reverse the plane for part of your planing because you always
: want to cut with the grain on the top layer of the plywood.

: Scribe a line on the plywood that matches the thickness of top layers of the
: plywood. I only cut down to the inside edge of the outer (water side of
: the panel) layer of plywood. Keeping the wood block flat to the panel,
: plane till you touch the line. Voila, perfect 45-degree bevel. By the time
: I got to my second panel, I could do about 15 feet in less than five
: minutes.

: Don’t worry about the holes in the planes. They don’t damage it one iota.
