Problem with pocket holes in plywood

I'm using a Kreg step drill bit, Kreg screws, and a "Task" brand (US made)
pocket hole jig from Lee Valley. I line up the two pieces of plywood flush
and drive in the screws. For some reason, the screws cause the plywood to
become offset so that they are no longer flush, with one face protruding by
about 1/16". What am I doing wrong?

Norm makes it looks so easy.

Are you using the Vise-grip clamp to keep the pieces flush while driving the
screw?

Sounds like you're not clamping sufficiently in the direction that the
movement is happening?

Ok, I tried clamping the boards together and now it works. Thanks everyone!

I clamp mine before putting the screw in.

That is absolutely your problem.. Since the screws go in at angle, the screw
will tend to lift the second board that it is going into. Use a clamp.

No, I've been holding them together with my fingers. Maybe that is the
problem.

Clamp them tightly to the top of a flat surface, like your workbench or
sawhorse, so the two pieces can't move on you. I use a couple of shop made
wooden "I" beams to do face frames this way. Clamp them to the table, and
the "I" beams give you multiple options for clamping your parts when doing
pocket hole joinery.
