Glenn's method is the most elegant, IMHO. Be sure to let the hardboard
acclimate to the shop before you cut it to size, (at least a day) if you
want a close fit to the raised edges. I built my bench using hardwood
edges and then cut the masonite to fit exactly. It lays flat (1/4"
thick) and looks fine. If I eventually ruin it all I have to do is lift
it up and cut and install a new piece.
