CNC cutting finger-joints

Some further thoughts: with a router I may have to fiddle with an additional backer board to sandwich both sides of the workpiece to avoid tear-out, so I might have to do a bunch of fiddling with clamps. Table-saw only requires one piece, which can be part of the sled. I don't want to sink time into a sled, but I see that there exist purpose-made box joint jig sleds with the capacity for tall boards like the Incra i-box, which is comparably priced to the dovetail/finger-joint router jigs I've been looking at. So that's another possibility. I'll probably go with the router jig if I can figure out a way to keep the 2nd backing board clamped in place while just moving the jig and it's backing board, or if I end up being wrong about needing the 2nd backing board.

In case it helps:  I have the Porter-Cable standalone jig and the Incra i-box.  I find the Incra much harder to use with wider boards since any tiny error in spacing compounds with the more joints you cut.  The Incra works great for drawers and other narrow pieces but I had trouble with wide pieces.   The Porter-Cable is a great jig---no complaints.  I've looked into the various Lieh jigs which look awesome but haven't pulled the trigger on one.
