Redrilling a door for a new lockset
I was recently confronted with the task of replacing a houseful of interior-door locksets. All the doors had three holes bored in their stiles — a 3/4-in. hole for the spindle and two smaller holes for the trim-plate screws. I had dealt with individual doors in the past, using sabersaws, rasps, and spade bits, and I had decided that I had already used all the patience I wished to allot to lockset replacement.
My solution to speeding up this job is shown in the drawing. I centered a length of 3/4-in. dowel on the pilot bit of a 2-1/8-in.-dia. hole saw. By using the dowel as a pilot through the 3/4-in. spindle hole, and by working from both sides of the door, I was able to cut clean, new bores quickly for the updated locksets.
