New Lock Set
The function of the tools I use and how they work are explained here. Specific tools used are noted in bold.
Because a new lockset is being installed, the old lockset hole is plugged with wood and then pour filled with epoxy. After this dries the knob edge of the door is trimmed off with a router, and a new piece of wood is glued in place. The trimming stops just shy of the interior cladding, thus avoiding having a visible seam on the inside.
