What do you do if you find your dado slot is a smidge too narrow for the plywood insert? I'm not familiar with a plane that pares the vertical surface. I sanded it but I was wondering if there's an easier way. Thanks,
Instead of widening the dado, you can also shave off a smidge form the mating piece. A regular shoulder plane works well for that.
Or "kill the wood" by hammering along the edge. This is a common Japanese ww'ing technique.Instead of widening the dado, you can also shave off a smidge form the mating piece. A regular shoulder plane works well for that.
