When Is 1/4" Not 1/4"?
Please explain why 1/4" plywood does not fit into a dado cut with a 1/4" router bit. I had to move the fence and rout twice to get the bottom to fit into the dado. Obviously the plywood is to thick, or the 1/4" dado is too narrow. The difference is too small for me to see. Which is more likely?
It's time consuming to have to cut the dado three times (shallow cut, full-depth cut, widening cut). The plywood came from Lowe's. There's nothing special about it.
