I built a jig for my table saw to hold picture frame at 45 degree vertically, to cut slots for reinforcing splines. (Thought about doing this on router table, but I do not have a slotting bit that gives nearly enough depth.)

Anyway, slots are cut, and splines are glued in. But, the splines I cut are oversized, and so I need to trim them. I am worried that trying to rout them with a piloted flush cut bit could splinter them, and remove part of the spline below the edge profile of the slot. (In other words, I want to end up with a perfect triangular spline in that triangular slot, but I'm worried the corner will chip out.)

I could trim with a small razor saw, and sand, but seems to be awfully time consuming - -there has to be a better way.

Suggestions?
