I used to use epoxy, but I went to double-sided tape.
You can buy A4 (12"x10"-ish) sheets of it, or if you look in
scrapbook/craft/junk places you can get rolls of tape up to 48mm wide that
work well. (Go for a visit anyway, sometimes they have interesting stuff.)
It's very thin. Cheap too, I've a 48mm x 10 metre roll here that cost me
$2.
Holds up fine, won't come apart especially if you are doing the 'solder both
sides for vias' thing.
I hold the boards up to the light, clamp them, drill a hole in the corner,
check for slippage, put a pin/nail/drill bit/etc through the hole I just
drilled (tight fit!), do the opposite corner. These are in existing holes,
usually for the screws.
Stick the tape onto one board, trim with a knife.
Take off the backing off the tape, put in the pins, put it on the bench,
carefully lower the top board onto it. Put a weight on it to make sure it
sticks.
If you want to be a little more careful drill a hole at each corner, a pin
in each.
A tip I picked up from an old school board maker is to bang those
registration pins into a board. Not only does it hold the board, but if
you're doing a bunch you can stack them high and drill them all at once.
