Of course make sure you particular saw has a perfectly square edge. I nice trick is to use the edge of your table saw as a 90° clamping jig. Take your time with this as it helps to get this right now. Make sure the two legs of the triangle meet at 90°. If there was one thing about this jig I would say is important this would be it. This is to allow 1/4″ – 20 carriage bolt heads to pass through. Make sure to also drill the larger holes in the end of the slots according to the drawings. If you do end up with some uneven spots or just want to clean up some burrs, try using some sandpaper double side taped to a piece of scrap wood. You can use a jigsaw as shown above.īut being the 1/4″ – 20 hardware has a 1/4″ square shoulder on it, I prefer a bit more accuracy.Ī trim router with a 1/4″ spiral bit installed does a much cleaner job when making the slots. Layout and drill the 1/4″ holes according to the drawings. The longest portion of the triangle is intentionally left long at this point. One piece has only one bevel on one end and the other piece has a 45° bevel on each end. Set your table saw blade to 45° and cut the two remaining pieces.

Again, you can find the free measured drawing here. Start by squaring up one end of your workpiece.Ĭut the first piece to length. All parts can be cut from one piece of wood 32″ long. I started by cutting my pieces to 7 1/2″ wide.
MITER SPLINE JIG PLANS FOR FREE
I made a set of measured drawings that are available for free if you are wanting to make this jig. One side is for cutting grooves into miters to accept splines, the other side is a simple but effective tenoning jig that works surprisingly well for such a simple jig. The first of hopefully many more add-on’s is my mitered spline and tenoning jig. I wanted to get the most out of it and use it as the foundation for other shop jigs. When I originally designed my sled, I had add-on’s and accessories in mind. This jig is rather easy to make, it’s inexpensive, and in addition to being a “double-duty” jig, it also utilizes the existing platform of my table saw sled. And I know first hand how expensive they can be, considering I have purchased some in the past. Another reason was to be able to do these joints without buying expensive factory made jigs. Being able to make accurate tenons as well as structural splines for mitered joints was the reason behind this build.
