Hi all,

Been making some cabinetry from birch ply for my workshop and so far have been making joints with a rabbet recessed into one of the surfaces and then just clamping and gluing up the four sides into a box. I want to build a bigger unit tomorrow and don't think that this just glue approach is sensible. Should I use pocket holes or some other technique? I don't want screws to be visible from the outside and am not sure about how pocket screws or any screws would work with this kind of rabbet joint.

I originally set out using the CDJ600 dovetailing joint on these carcasses, but found that 18mm ply was really hard work for the router and I ended up with lots of burn.

Sorry I can't post pictures on here, this is my first post.

Thanks in advance.
Joe

Rabbet = USA
Rebate = UK
:)

Glued rebates are a perfectly valid way to do drawers like this. Last time I made plywood drawers, I used Festool dominos. I suppose if you wanted to re-enforce your rebates, you could use dowels.

Rebate for the back, housings for shelves, dowels or dominoes for the corners.
Clamp and glue everything together. No screws needed.

A lot of the strength/rigidity comes from when you apply the backing. Depending on scale, glue might be fine.
