Ian Kirby writes in this series on mortise-and-tenon joints about how to use tablesaws, radial saws, drill presses, or routers to make them. He begins by making the mortise, drilling a series of holes to remove the bulk of the waste. He says the diameter of the drill should be 1/16 in. less than the width of the mortise chisel that is to be used to clean out the remainder of the waste. He addresses mortising machines -- how they work, how to set them up, and how to use them, though he thinks they are frequently priced over a hobbyist's budget. He cuts tenons on a tablesaw, bandsaw, or router, or on industrial tenoning machines. He devotes a section to using a router as a mortiser and explains how to avoid injury.
