Default Enlarging an existing door knob hole...HELP!

Strange, I had this exact problem last night. I was installing a lock
and the hole needed to be 1/8 inch larger. I just put a wood boring
bit into my drill and carefully got it started and widened the hole.
The sides of the boring bit are slightly tapered so it guided it right
through.



You could make a quick jig, 2 pieces of ply or mdf with a piece the
thickness of the door sandwiched between so that you have a U shape to
slip over the door. Determine the distance between center of hole and
edge of door, drill a hole the appropriate size in your jig at this same
location and then use the jig to guide a hole saw.
The whole thing shouldn't take more than 10 minutes to make up, and
could be used for setting up holes in new doors as well.

Too bad it's a mail order thing. I generally stay away from mail
order.

That sounds very useful to have around.

As far as a me too answer, I was going to suggest using a hole saw or
fly cutter to make a plug the size of the old hole, and using that to
guide in a new hole saw. I don't know if that would work. The mail
order gadget sounds much better though.
