I don’t have a mortising machine, and until recently I used my drill press instead. But, in the middle of a mortising job, the motor failed. Then, while considering the options, I reached for my clamp-on doweling jig. Turns out, it works great for the task! Just drill a series of overlapping holes, starting with the mortise ends. Re-clamp the jig for each hole to hog out the mortise. I find the doweling jig makes mortises as well as my drill press did.
