A short time ago I posted as a project a (tablesaw spline jig) that I had made after viewing a video on youtube, well IMHO it was a failure, so after receiving comments on the posted project (spline jig) from other members sharing their jigs I found Andy's to my liking so I scrapped the first jig and reconstructed a new one using scraps to match Andy’s and it’s a whole lot better, it allows you to view all angles of the cut and height of the blade in which my previous in the link above didn’t.

Here is the new and improved jig.

Wow. That’s way better than my piece of crap. Needs to be next on my list.

Randy, I like the basic idea of this jig. It looks like it will run true and lets you measure directly for the height of the blade. Setting the trough sides high will keep it from getting too chewed up with your cuts. However, I would make the trough boards longer so you can slide the box along and make consecutive cuts on one corner and then turn the box to the next corner. I use a simple masking tape and pencil mark to locate my placement for splines. It is fast and accurate enough for box making. Mechanically moving the fence or a stop takes way too much time. Here is my version of a spline cutting jig. With this I can lay out and cut 16 spline slots in a box in 5 minutes or less, and I can set the jig on the floor next to the saw and it is self-supporting. Andy’s design is a good one and may work better for what you are doing, but this works well for me on large and small boxes as well as trays.

Here is what my version looks like. There are other views and explanations on the link.

Looking at yours big Al, it looks like it would suit me more as I somethings have the tall 13” + boxes and I can see how yours could go faster, not having to reposition the fence instead simply moving the box to it’s new cut line.

There are a lot of similar varieties of spline jigs used and made by lumberjocks. I’ve made mine with a guide strip on the underside that fits into table saw top guides and router table. It can cut three different spline angles on the table saw and dove tail splines on the router table. I use a stop block on the sled to position my box for spline locations and move it as required. So far I’ve only used it for 90 deg splines. I need to add a few more options to it and will post when completed.
