Tricks of the Trade
EDITED BY PAUL ANTHONY
Safer Sheet-goods Sawing
I use a portable circular saw to break down plywood and other sheet goods into manageable pieces before bringing them to the table saw for final sizing. I prefer to do the j ob on sawhorses rather than crouching on the floor. Unfortunately, you normally need three or four horses to provide enough support to prevent cutoffs from binding the saw blade and crashing to the floor at the end of the cut.
My trick is to use a full sheet of 2"-thick rigid foam insulation (available at home-supply stores) as a cutting platform straddling two horses. I lay my plywood on top, and clamp it and the insulation board to the sawhorses. I adjust my saw blade depth to
Offcut fully supported after cut
cut no more than 1/8" or so into the insulation board (always cutting into the same face to preserve strength.) I can now make my cuts safely and securely with all pieces fully supported at the end of the cut. If necessary, I can clamp workpieces or straightedge guides anywhere I like by removing the jaw from a clamp, poking the bar through the foam board, then reattaching the j aw. When I'm done cutting, the lightweight insulation board stores perfectly with my other sheet goods.

Vise in a Vise
I don't use my machinist's vise often enough to dedicate any of my limited bench space to it. Instead, I keep it tucked under a nearby cabinet for occasional use. I bolted the vise to a board that has a heavy cleat glued to its front edge, which allows me to clamp the whole setup in my bench vise. It's a quick and easy changeover that provides for secure mounting in use.
