This question relates to woodworking… Let’s say I create 2 panels and I want to join them (one perpendicular to the other) using a wedged mortise and tenon (actually 2 mortises and 2 tenons). This requires mortises that are wedge shaped - e.g. 12mm x 25mm holes on one side of one of the panels and 12mm x 19mm holes on the opposite side of the same panel.
The best technique I could come up with was to push one of the edges back, then draw the trapezoid shapes on the “new” edge, then, with the 3 new edges (created by the recessed trapezoids), I would pull them out by 3/4” (the thickness of the tenon that will be inserted in the hole) Then create a new panel that’s butted up against the edge with the cutouts. Then join the two panels together by erasing the lines that divide them… except that doesn’t work. When I try to delete one of those lines, I end up deleting one of the faces on the panel.
If I could just attach a 12mm x 250mm (x 12mm thick) panel to the edge where those cutouts are and join the two together, I’d have exactly what I want.
Can anyone tell me the right way to do this? The attached picture should clarify what I’m talking about. The front edge (on the left) is where I pushed it back and made the trapezoidal cutouts The opposite/back edge (on the right) shows how it’s supposed to look - except the mortises and tenons are straight through, with no wedge shape.
