With the tongue and groove joints cut, the next step is to assemble the boards that will make up the cabinet doors.
Apply a thin layer of glue to all surfaces of each groove, and insert the corresponding tongue. Immediately wipe off any glue that seeps out of the joint, as the glue could cause an issue with finishing the cabinet door later.
When all joints have been glued and assembled, place the entire assembly into a set of woodworking clamps. Tighten the clamps enough so that the joints are closed tightly, but not enough to squeeze the glue out of the joints.
Set the entire assembly aside and allow the glue to dry for 24 hours.
