The technique shown here is focusing on a broad, mitered, flat corner, like a simple picture frame, where the hypotenuse of a 45° corner measures more than 6” or so. Again we’re geared toward production shops and factories where they may have 100s or 1000s of these corners to mill. We want to do this with markless indexing as the Versidex MEGA always does.
So we’ll make a dedicated PLATFORM TEMPLATE (a vertical template is not needed) to add to our “library” of template sets, and it will look very different from any of the others, although it will still index the pieces from the dual stationary fences. In the indexing set up, we’ll also use FENCE SPACERS (for narrow pieces), FLIP-STOPS for repeated positioning, and T-track HOLD DOWNS when the outside mitered corner has to be positioned too far from the pressure bar for it to properly reference the piece from the template surface. As the width of the piece increases, so does the need for clamping help.
Next, we'll construct a 3-dimensional template to reference a held-together, unglued, assembled flat miter joint to take advantage of the pressure bar while we mill a double joint ACROSS the held-together joint, the second cutting using a crosspanel spacer to reference the joiner. Assembly is finalized using glue and Lamello's E20-L tight-drawing half biscuit (the elongated one).
When you want to put the Lamello E20-H (the narrow, upright one) into the EDGE of the joint, the technique is similar to bevel-edge-to-bevel-edge milling. Pieces are loaded differently, though, so that you get a mortise cut straddling two pieces, just like with the E20-L cuts, but the E20-H mortises are cut into the beveled edges, using the joiner's front flap as the referencing surface.
