Figure A: Outfeed jig
Build this simple outfeed jig from ordinary 3/4-in. plywood and 2x4 scraps. Be sure to screw the jig to the plywood base of the saw for stability (your saw base must be screwed or clamped to the sawhorses as well). You won't need anything other than a single 2x4 for the far leg support.
