I have an interior door that I wish to change to a set of new locks.
The new lock calls for a round hole of 2-1/8" in diameter on the door slab, and 1" hole on the door edge. Pretty standard.
I took apart the old lock and found out the hole is only 1-1/2" in diameter, and the two screws that feed through the door, has their own small holes outside of the 1-1/2" hole.
I need to enlarge the existing hole to 2-1/8". Problem is I have nothing that I can drill into to center the hole saw to make a bigger hole. I think I can clamp a piece of wood on the backside of the hole and that may work.
The other issue is I have a set of hole saws and the closest to 2-1/8" is 2" and 2-1/2". Can I use 2-1/2" which is just a tiny tiny tad smaller than the cover plate of the locks? or is the 2-1/8" a rigid requirement?
