How to fasten several sheets of plywood.

Fit the jig over the end of one piece of plywood to position the sleeve. This will give you tons of contact with long grain to create a really strong glue joint. Insert a drill bit into the sleeve and drill the hole at an angle through the end to penetrate through the face. Using my experience i would fasten the underlayment with adhesive and 7 16 inch crown staples every 6 inches driven with a pneumatic stapler.

If you use adhesive for the underlayment you can get away with fasteners every 8 using ring shanked nails. The only caveat is if you re trying to used pre finished plywood the finish would get in the way of the glue. Screws fasten the scab to the other two pieces in addition to the glue. The screw holes should be on the bottom.

It sounds like you re planning to stack two sheets together. Using 1 1 2 inch flat head screws and yellow glue fasten these posts to the sides and ends. Drive the screws through the plywood into the frame countersinking the heads below surface. For the 1 2 underlayment ideally you want to screw every 6 all across the panel.

After adding glue the two pieces are screwed together with glue and optionally bar clamps.
