Yes it’s ugly, yes it’s a hack, but it works.
I am working on a box now (thanks to boxguy for tips and inspiration) and I have never really made a GOOD one using proper technique. I am not overly thrilled with the look of box joints or dovetails. I purchased a lock miter bit, but am not super happy with the fit. It’s REALLY tight without glue. That leaves me with the dreaded splines. I don’t know why, but I have always been terrified of splined miters.
I decided to give it a go. I had an old cross cut sled that I took all the t-tracks and good stuff off of. I was going to chop it down to make a spline cutting jig, but then I had an idea. I just made one that attached to the sled with the t-track clamps!
I cut the 1/2 plywood into two wide pieces and two narrow pieces. I then put two identical speed squares up against the cross cut fence to get my 45 degree angle.
I layed the plywood on the speed squares and applied some glue to the edges. I attached the sides with clamps and some 18awg brads.
I then put the the other angled piece on. I glued the edges and loosely clamped it to the sides. I slid my speed squares under to get it aligned then hammered down on the clamps and drove some brads.
After that I attached 2 pieces of 3/4” ply to the sides so I would be able to clamp them with the T-track clamps.
The block inside is what I use for a stop block.I just clamp it in place with a quick grip 90 degree clamp.
It works AWESOME! I am no longer afraid of splined miters.
