Using the traditional angle checking tools, such as drafting triangles and squares, still is a good place to start when building tablesaw sleds, especially miter sleds.
I don’t trust miter guages to stay on angle throughout a whole job. A picture frame, for example, has 8 miter cuts and just a small bump on a common miter guage can cause it to lose its setting between cuts. So I rely on fixed, shop made miter sleds. But making sure they’re exactly at the desired angle is critical.
So here’s a video I made to show how I do it. The sled I used for the video is one-tenth of a degree offf.
I got the idea when I saw another woodworker show how he sets his adjustable miter guage. I use a Wixey Digital Angle Guage to do it.
Here;s the link to my YouTube video:

Next time I want to make a short video that shows my method for checking the table saw fo accuracy.

Don, maybe I’m missing something, but I don’t see where that method proves anything. A perfect 45 degree reading would mean nothing if the base was not square, or if the runner was out of square with the base.
It seems to me like a better way would be to zero your gauge on the runner, because what really matters is the relationship between the fence and the runner, right?

I think he trued the boards edge after installing the runner, which would make the runner and board (base) square to each other. Then you set the miter with the wixey.

Good video Don. I do the same thing with all my jigs that require angle cuts that are repeatable.

charlie,
Yes,
The edge is trued by simply passing it through the cutpath after the runner is installed. That makes it perfectly parallel to the runner.

Thanks, Don. I should have known better than to question you. :-)
