Setting up saw blades for slot cuts in box corners.
Here is a quick way to set up your saw for cutting spline slots using a spline cutting jig and a dado blade. This method involves no measuring and take only a minute or two.
The trick is to use brass set up bars.
I keep my set close to the dado saw in my shop.
Hold the largest bar on a 45 degree angle on the corner of the box.
Add other bars until you get a combination that is just a little under the width of the box corner.
Now move these bars to the saw blade and crank it up or down until you have matched the height of the saw blade and the height of the set up bars. A finger touch will tell you when they are even. The blade tooth needs to be top dead center when you measure.
Now you can cut your spline slots without fear of cutting through your box corners. Have fun and look at my blog tutorial on how to build a slot cutting jig.
