You know you can put the tenon cutter on the other side of this jig. Mine is 2 sided. One small fence for cutting width wise and one very wide fence for cutting the board depth wise (the edge of end of the board). I’ve never once used the wide fence. I think I’ll modify that side to become my spline cradle. Here’s a couple of pictures. I think modifying the long side shouldn’t be too difficult.
