The next time you use your saber saw, forget about hauling out the sawhorses
or cantilevering a hard-to-hold workpiece off your bench.
Extruded polystyrene insulation board, the rigid pink sheets used in housing
construction, makes saber-sawing easy, whether you’re cutting a small
piece of hardwood or a full sheet of plywood. During the cut, the workpiece
is always fully supported, so your saw has constant, stable support.
The 2-in.-thick insulation houses saber-saw blades as long as 3-1/2 in. The
same piece can be used repeatedly; one 4-ft. x 8-ft. sheet (about $17 at
home centers) will probably last you a lifetime.
