Some of our doors have knobs, which we like (like idiots, we tend to

doors with knobs is that one's hand is a little too close to the frame
for 100% comfort :-) I wanted to fit some latches with longer backsets
(the 83mm ones seem about right), but they won't fit in the holes cut
for the existing latches. I need to enlarge them by a couple of mm.
I'm imagining that if I just try to offer the bit up to it, it will just
bounce all over the place, so I'm not going to try that. Right now,
the only thing I can think is to glue a bit of wooden pole in there and
start again. But is there another easier way, I could do it? I'm not
even sure that I could source the wooden pole/dowel of the correct
diameter.

If the hole is nearly in the right place, enlarge with a round wood file?

If it is miles out, you'll have to plug it and start again. You can buy
plug cutters in most tool places - you cut a plug from a similar type of
scrap wood and glue in place.


It's just a couple of mm, but too deep to file, I think. I hadn't heard
of plug cutters, but I'll take a look.

A half round rasp and some elbow grease should get it then.
