In the past, I’ve never found the marked angles on most miter gauges to be accurate. I’ve always relied on a plastic protractor to set my miter gauge at specific angles. To speed the set up of angles on my miter gauge, I came up with a quick solution. As you can see above, I marked common angles on the edge of my table saw table. I simply used a permanent marker and a protractor gauge to draw the lines. You could also use a scribe for a permanent mark. Now, instead of reaching for my protractor, I can simply lay my miter gauge on the table and set the runner to the appropriate angle.
