1/16" or 5/64", anything larger the threads of the screw won't get good bite.

when i glue to pieces together, i apply lots of glue, put a few screws in where i plan on cutting off, then drive my car on it and let it sit for an hour or so. Extreme clamping pressure.
Sometimes use another piece on top and bottom to distubute the weight evenly.

If it's a flush mount I cut the wholes before gluing. Otherwise I don't see why it would matter.

I would imagine its a little bit easier to the hole before you glue them. A jigsaw or router going through 3/4" instead of 1.5" is a pretty big difference.

im using a router and puting a 2 in bit on it so its perfect and not off.
