When I go to Home Depot and buy a 4×8 sheet of plywood, often times I have them cut it at the panel saw. The guy stands the sheet horisontally and the circular blade of the panel saw cuts it left to right.
The question is – how come the saw blade is not pinched? Near the end of the cut there’s almost a full half-sheet of 3/4″ unsupported plywood right on top of the blade. What keeps the panel from squashing the blade?
I’ve never noticed a burn or a non-straight edge or any other sign that the blade is getting pinched. There must be something I’m missing.
