Also, the pegs will get (just before glueing) a hit from some
sandpaper so the glue will adhere?

Two good possibilities: saw a slot in the peg, and wedge it
slightly (the wedge and slot will be hidden in use).
Or, get the right size drill. 12.5mm is .492125 inch, should
work well. 31/64 is .484375, so if you rough the
peg with some 80grit sandpaper, it'd work, too.

To get an accurate diameter hole in wood is not easy, unless
you use Forstner or (sharp) auger bits. To do it with twist drills,
first make a pilot hole with 13/32", then clean it up with the
fullsize drill. Wood is capable of grabbing and steering the
bit that removes most of the wood, but a careful hand-held
drill job that removes only the last .080 or so should work well.
