Spline Jigs seem to be pretty ubiquitous. The interesting thing I noticed in looking through all the LJ spline jigs though is that they are all quite different. People have thought of a lot of different ways to do a spline jig. Where as something like a crosscut sled seems to only appears to come in different sizes to me. Any who, here is my version to throw on the pile and help spark some ideas.

This jig helped me out with a large picture frame project and worked like a charm. the sliding section lets me set the spline position, and makes it repeatable. The base has slides in the miter grooves, so it doesn’t rely on the fence. I started by building the 90deg inside saddle, then positioning with a number of 45deg cut offs. the two close together in picture two help keep the blade buried. I finished in BLO, and am very happy with this jig.

Sweet Harold! How about this weather? Crazy wind, first it was 90, now it is in the 60s. I finished the picture frame a while back and gave it as a wedding present. I will have to post pictures from the next frame.

Hey! who you calling sweet??? :~)

No joke! That rain storm came in with a fengine. Thank God, though, as we need the rain.

BTW – I like your “eccentric” tag line.
