This is a very simple attachment to cut 45 DEG. mitre and spline slots for boxes .
I made this because a lot of times the box sides are too tall to fit on the mitre saw and this is a simple and easy to make solution that attaches to just about any TS sled with a C CLAMP .To cut the box sides I cut the sides to just slightly oversize in length and cut the mire on one end on the long pieces and then set the jig to exact length and cut the mitre on the opposite end and then repeat this on the shorter pieces .I undercut the end of the stop block to protect the mitred end ot the board and use the face of the mitred end instead to set the length .
The spline grooves are cut the same way but I use the the sled base as a index for this and use the toggle clamp as a hold down also . This simple jig is surprisingly accurate and quick and easy to use .

Looks great Klaus but needs marquetry. I like the clamping idea and the dual use for mitre and splines.
.... clever….

I was going to say slick too. It sure is a easy and different way to do it. I’ll take two birds with one stone anytime.

Great design, Keifer. I’d guess you had this one in mind for a long time. Enjoy and keep making lovely boxes.
