Enlarging cross bores in entry doors
We have double doors in our entry. Both doors open, but one is usually stationary, with top and bottom sliding pins holding it in place.
The deadbolt in the active door is messed up, so I'd like to refinish the doors and replace the handlesets.
The diameter of the existing holes (cross bores) for the deadbolt and handlesets are 1 5/8". So far, I've found only Weslock handlesets to fit the existing holes. 2 1/8" seems to be standard and is required for a Baldwin handleset I'm considering.
I called a locksmith to inquire about enlarging the 3 cross bores (deadbolt and both knobs). He would charge $55 for an estimate or $55 + $65/hour to enlarge the cross bores, but wouldn't estimate the time it might take. The doors are solid pine and original to the 1964 house.
It seems it would be easier to cut the cross bores in a new door than to enlarge existing holes. Is this something I should consider tackling myself. Lowe's has a lockset template kit which includes a plastic template that straddles the door and a hole saw. It's only $13 and got mixed reviews for ease of use.
