I made my first attempt at stack cutting today. Frankenstein on three sheets of 1/8 inch plywood. I used painters tape and spray adhesive to plant the pattern and wrapped the whole stack with packaging tape. I should have sanded all of the boards prior to cutting because 1/8” intricate spots will be scary to sand now. Tear-out on the bottom piece was pretty bad... I used a #3 FD new spiral... I have a dozen #2 pegas spirals on order, maybe these will work better?!?!?! I included my Jason Voorhees on 1/4” oak too! Fun pattern!
