Take a look at this picture. It’s the top of in easel where there is an inner frame (on the right) sliding inside of an out frame. The plan calls for me to slot the 3/4” thick outer frame member and insert a “tongue” to ride in the grooved edge of the inner frame.
How would you make that slot in the end grain? Keep in mind this is a 6 foot long …. oh, let’s call it a 1×4.
I was considering just notching the end and making a block with the tongue built into it. Grain of the block perpendicular to the vertical grain of that outer frame member.
I had thought about making mating rabets (oh that sounded dirty) in the outer and inner frames running the full length of each, but I am concerned that any warping or bowing of a frame member would bind the whole thing up tight.
The purpose of the tongue and groove is simply to keep the inner frame from flopping forward and falling out of the outer frame. The inner frame “traps” the outer frame at the bottom (of the inner frame) with no need for tongues or grooves.
