Festool Tracksaw Kerf Wedge

I was sawing a long live edge piece of lumber and the kerf closed up on my blade causing slight kickback. I wished I had this when I was doing the cut so I designed this. You just place it in the cut kerf as you're going or stop the saw, place it in and keep going. It will hold the cut from closing in on your blade to prevent kickback.Print vertical on end without issues.TS55=2.2mm kerfTS60=1.8mm keftTS75=2.4mm kerf Not required for plywood. Sometimes the pinch is so strong from the stress of the wood the saw riving knife isn't good enough, you can use multiple along a long cut.
