In another situation I drilled a hole for a dowel through both pieces
of wood, glued the dowel and hammered it in. But stupidly I had not
previously located a suitable punch to punch it right through into the
second piece, and by the time I did find one (30 seconds) that dowel
was immovable. I've done this before and it works fine as long as one
does not pause even for a second whilst hammering it through.

This is Evo-Stik Weatherproof Wood Adhesive, by the way.

I fill the hole in the outer piece with another dowel cut off flush,
then planed or sanded, by the way(2).

It sort of dries out to grab, then seems to set in some mysterious way.

It loves porous wood.

It has an affinity for most things, especially the spout of the plastic
container it comes in.

Yes, it dries hard after a week or two, but on wood it seems to "take"
in no time. I usually leave a joint overnight, but I've noticed that
joints are rock solid after just a couple of hours. I wouldn't like to
subject them to the full working load, mind you, but if one is glueing
and then screwing afterwards, it's not necessary to wait 24 hours.

BTW, anyone know why we used to use horrid-smelling fish glue at
school? It was kept warm in a pot of hot water, as I recall. Wasn't
PVA around in the 1950s?



Animal glue in a gas heated pot used to be used in my woodwork class in the
70's ......... and PVA was certainly about then.
The advantage of hot melt glue was that it was gap filling and set as soon
as it cooled.

Axminter still sell the stuff.

Elf & Safely ... probably wouldn't let school kids near it now.
