You can greatly reduce the fuzzing and tearout that goes with ripping plywood across the veneer grain by first scoring the lower side of the plywood with a shallow cut of less than 1/8 in.But this requires lowering the blade to make the scoring cut then raising it again to make the finish cut.
These fixtures allow you to make a scoring cut without all this fuss.Just put the two fixtures in place, one against the fence and one near the blade, and push the panel through to make the scoring cut.
Then remove the fixtures to make the finish cut.Dowels on the ends of the fixtures prevent them from sliding forward during a cut...
