This is a variation on a jig a fellow Lumberjock posted some time ago. It’s purpose is to prevent the dangerous situation shown in the second photo. Stops on miter fences and cross cut sleds are fine for pieces over one inch but can fling a short piece back in your face if it gets caught between the stop and the blade. This can be prevented if the miter and cut off piece is pushed all the way past the blade but then I have to reach over the blade to retrieve the piece.
The key to holding the jig in place are Madswitches (photo 3) which are available at Amazon, Rockler, etc. Turn the knob and you have 90 pounds of hold-down force. Drill a 30 mm hole in any 3/4” stock, insert, place on the table or band saw table and it replaces all those clumsy clamps used to hold down jigs.
Back to photo one. Cut a curve in 3/4” MDF and glue on a piece of brass shim stock (.012” thick) on the curve so it hangs over the end of the curve. Move the jig so the shim stock rubs against the back of the blade just below the teeth to pick up and guide the pieces around the curve. Fill any miter slots in the table near the discharge end of the jig so the pieces don’t get caught. Place a stop on the right hand side of the blade, advance the stock to the stop and cut away. Photo 4 shows how the pieces march around the corner and away from the blade. Photo 5 shows 8 feet of stock cut in 10 minutes.
