[alberg30] Remove step plate

[Guy Lalonde]

From: Guy Lalonde <lalondegc at videotron.ca>

Joe,
masonite can be had in most lumber yards and is available in different
thicknesses. Basically those peg boards you put hooks into to hang tools is
masonite. My understanding (my 2 cents' worth) is that some grades of
masonite have been soaked in some kind of solution and I don't know if
fiberglass / resin would adhere well. Test it beforehand.

As Russ was saying, if you use plywood get marine grade mahogany plywood. It
has less voids, I think it has more layers than an equivalent thickness of
regular plywood and the layers are glued with waterproof glue.

Or maybe use a solid piece of mahogany. Probably cheaper to buy a plank of
solid mahogany (or leftover pieces in a lumber yard) than buying a whole
sheet ( 4' x 8' ) or half sheet of masonite or marine plywood.

Again: my 2 cents.

Cheers,
Guy.
