Two mortises are almost as fast as one.
You just
need to stop to pull the guide bearing out of the
center slot of one template and put it into the
other.
Make a test run.
To be sure the mortises and ten-
ons will fall in the right place, cut mortises in some
scrap.
Two tenons in one minute.
Like before, use climb
cuts to make a series of shallow passes, working
your way toward full depth, and adjust the guide
bearing outward, down the taper to dial-in the fit.
