Back when I bought handles for the pantry and mudroom closet doors I purchased extras for whatever might arise in the future.
They were on a good sale, I liked them, and I wanted the handles throughout the house to match.
When the conservatory and master bedroom doors were installed I got busy putting handles on the double Shaker-style doors.
First I marked the holes for the handles (2 for each) similarly to how the pantry doors were positioned.
Then I drilled the holes.
Each time I needed to enlarge the hole just a bit so the part of the handle that inserts into the wood was able to fit. I used the same drill bit and just grinded it around a little. Drilling a second hole was not an option on these natural wood doors.
The screws that came with the handles were too short for this installation so we bought additional longer machine screws in the knob department of Home Depot. Actually I ended up making 2 trips because the first selection was still a bit short. Then I got the bright idea of taking a screw out of the already finished handles to measure against at the store. I know: Delayed genius is no genius at all.
The handles didn’t insert all the way into the door until the screw was tightened against it.
Voila! Handles on the double doors.
Are you handy with small power tools? Do you measurements sometimes lack the desired accuracy?
