I’m cutting 5 mm plywood with lots of small parts and several large parts in each panel. I’m using tabs but I’d like to incorporate a vacuum table because even clamped down on all edges a 17" wide piece of 5 mm ply raises in the center of the panel from the pull of the router bit cutting. I think if I used the onion skin (along with tabs because I can) with a vacuum table than I could eliminate this raising of the center of the panel. I’ll post any success I have. I had thought before about this but didn’t include the onion skin which maybe won’t break the vacuum pull and loss of vacuum effect since tabs along would ruin the vacuum pull. Thanks for musing about this, I have an a/c vacuum pump and think I could just pipe a shutoff switch into the line but need a large piece of thick rubber for the overall vacuum pad. Or peg board sealed and dotted with o rings on top of a thick panel with lots of narrow slots. Of course I could packing tape the whole waste board and spray glue the 5mm ply to the waste board to eliminate the raising of the center and tabs might be all okay without a vacuum enterprising complexity. Thanks for provoking my thoughts.
