Do you see any problem putting decking type screws between slats when making a cutting board. This would be done to help hold it together while glueing and for added strength and resistance to bowing. I seem to have trouble when I just clamp everything. It gets bowed. my plan would be to pre drill holes and screw together 4 slats at a time (and also glue). Then I would attach these sub assembles and glue them together somehow. Maybe inserting dowels for extra strength. Just been thinking. I am using maple.

One possible cause of bowing could be your clamping pressure may be
too high. To counteract the bowing, cauls positioned above and below
your work piece and perpendicular to your clamps could solve the
problem.
