Splined Miter Jig

Inspired by The Wood Whisperer, I decided to make my own Splined Miter Jig since I plan on making at least one (I know it will probably be more) of his clocks. I currently only have a portable DeWalt tablesaw due to my limited space, so I scaled the jig down a bit. Mine is 10’’ long, 7’’ tall, 7’’ deep, and the support blocks are 5’’ x 5’’. The 45 degree blocks are 2×4 blocks cut down to 5’’ long, right at 3’’ tall, and are the standard 1.5’’ thick. All plywood was 3/4’’ Birch scrap. I think it turned out pretty decent. All I lack now is deciding what woods to build my clock out of, haha.

Very interesting. Have you used it yet? It looks sturdy, but I wonder, is the base piece of plywood big (Long) enough. I would be interested in knowing how it works for you.

Thanks.

I will be using it in the next day or two, hopefully. I will let you know how it does and i will try to remember to take a couple of pictures of the test piece for you.

Making jigs can be pretty fun. It looks like this one should work. It will hold the work and keep your hands clear.

I look forward to seeing the projects that you make with this.

I have to agree with everyone else.

I like the Structor, I like the Beefy wood to hold your Work pieces for the Splines, I think it will work very well for you.

And best of all, you have no Indications of Nails or Screws in the 45’s so no problem with Making Splines as high or low as you need them.

Thanks guys. Yeah, I didn’t want any fasteners shown on the front of the 45’s so I glued them, clamped them, and then while they were clamped I shot 2’’ brad nails through the back of the face piece into the 45’s (5 into each piece). I think they will hold up pretty well. Not sure if I will get to cut a test piece today or not, depends on my workload. If I do, I will upload some pics later on in here.

Well here is the test run. I just threw the miter joint together quickly last night so i could have one to test today, so it ain’t purdy, haha. I set my blade to 3/4’’ deep for the first cut, which gave me two 1’’ slots on each side; and it was 1/2’’ deep for my second cut, giving me two 5/8’’ slots on each side for it. We then grabbed a chunk of cedar we had laying around from when i made a bowdrill set, and cut the splines out of it. Somehow we got lucky and cut them the EXACT thickness to snugly fit in the grooves on the first try, haha.

All in all i think it is going to work very well. The jig worked perfectly for my small table. Ran smooth as silk.

Here are some pics, notice how safe my dad is being whilst ripping down the cedar log, hahaha. I tried to advise him against it, but he was determined to rip it down.

Looks like a great jig for cutting the slots. And lets hope that you are always so lucky when cutting your splines.

I’m a bit new to splines. Do you simply glue the cedar inserts into place? Or you you glue and brad them? Also, once they have dried, do you chisel/sand the spline to remove the excess wedge? Thanks.

This jig really looks great. I think have more jigs than I do finished projects.

You glue them in place and after it has dried you take a flush cut saw to them. Then sand it for a perfect fit. Check out The Wood Whisperer’s video here, http://thewoodwhisperer.com/72-contemporary-clock/ This will show you the proper procedure.

Thanks for looking
