I have to secure a workroom with a mortise lock so got to it this very morning.
Step 1. After measuring and marking out, remove the majority of the timber using an auger.
Step 2. After squaring the mortice with a chisel,make a trial fit and adjust the size as needed by shaving a bit off the sides using wide chisel.
