There are five different size Domino tenons, but only three width settings on the machine, how come?
The width setting on the Domino joiner is not what determines which size Domino tenon you use; the Domino cutter and the depth setting determine which Domino tenon you use. The four different size Domino cutters (D5, D6, D8 & D10 millimeters) correspond to the thicknesses of the different size Domino tenons. There are five Domino tenon sizes — 5 X 30, 6 X 40, 8 X 40, 8 X 50 or 10 X 50 millimeters. The green knob on top of the Domino joiner is to set mortise width. When using the stop-pins to index off an edge of a work piece, use the first setting. This will cut a narrow slot for a tight fit to align the piece. The wider mortise settings are for running Domino tenons in series using the cross stop where precise alignment is not necessary. Using the cross stop to cut mortises saves time on layout and assembly.
