Using my bandsaw and a tapered sliding fence, I can saw variably-spaced tails that look hand cut more consistently than I can with my dovetail saw, and in about the same time that it would take to set up a router jig. To make this tail-cutting jig, saw a 7-9° taper along one edge of a 6×24" board and attach a stop to the back end.
After laying out and marking the tail board, position it against the tapered fence, line the blade up with your cut line, and saw up to your shoulder line. Flip your board to cut the opposing angle. To minimize chisel work, you can also use the bandsaw to nibble out the remaining waste between the tails.
