Mike what have you got against using a chisel? It's not that hard to do. If you don't know how to use a chisel you should learn. Chisels and plane should be part of your woodworking. I don't use them much but they do come in handy at times. I am still learning how to use them plus a card scraper. I am sure not a woodworker that uses all hand tools.I have rabbeted out the back of some boxes with a 3/4 x 3/8 rabbet bit for the backs. Wanting to square the corners out. Any Slick way to get them square
Other than useing a chissel ??
