Simple shelf joint?
First time building a cabinet... I am building a basic bottom cabinet. box is 3/4 birch ply. The sides will not be visible, so I was debating the merits of pocket screws vs end screw to attach bottom and fixed shelf to sides. I plan to glue the joint, so I am guessing either screw method will work fine, but was just curious which actually provides a stronger connection (if there were no glue)... pocket screw on bottom of shelf into side, or screw through side into end grain of shelf plywood. I read that the limiting factor is pull through of the head and not face vs end grain for the thread side... using Spax screws.
After thinking about the above for a while, I am leaning towards a dado in sides for shelf and bottom... and glue, obviously... in that case, I assume a pocket screw would not work since with the dado there is not much side thickness to screw into... so I assume that I could use a screw from outside into end of shelf... or is it better to just, glue, clamp and no screws at all?
