re: Question on Spline Jigs

I would think you’d need to have an adjustable side no matter what, since you need the spline to be centered on both sides, so you’d need to adjust the jig to cut equally on each side. I still think you could do it with one ‘wing’ and clamps, but it’s still got to be adjustable…

Mine is just a simple 90° jig with a miter gauge slide on it…
