Could someone explain to me why I didn’t think of this ? Brilliant.

Figure 1
MiterSet consists of a plate with two arched hole patterns, two tapered pins, a detent bar, and a miter gauge slot. Each hole is 5° apart as engraved in the plate. In (figure 1) the pins are located in the bottom most holes. This allows your miter gauge to be adjusted exactly at 90°.

Figure 2
(Figure 2) Your miter gauge has been inserted in the miter gauge slot, and adjusted to contact both pins for a 90° setting. Tighten the adjusting knob, and you are ready to take it to the saw and cut a perfect 90° cut. Don’t be surprised if the factory stop on your miter gauge is not adjusted to this new setting. After you are satisfied that MiterSet has done its job you may want to adjust the factory setting to match.

Figure 3
Let’s move on to both of the 45° settings. (Figure 3) shows the tapered pin relocated for a right-handed 45° setting. We already slid your miter gauge against the pins, all that is left is to tighten the adjusting knob and take it to the saw. Again, once you are satisfied with MiterSet’s performance you may want to readjust the factory stop. To adjust your gauge for a left hand 45° angle simply use the other 45° hole and the opposite pivot hole. Re-adjust the gauge to this new pin position.
Note: the two holes that are marked with the 00 are called pivot holes as all angles pivot on their location.

Figure 4
Now the fun starts. I will randomly pick an angle at which to set the miter gauge. Let’s say you need to cut a 35° angle for a project. With MiterSet it is so simple! I’ll bet you already have it figured out. Yes you are right, simply place a pin in the 35° hole and the opposite pin in the pivot hole and you are ready to slide the miter gauge in the slot against the pins, and tighten it down (figure 4). You have just set your miter gauge to 35° for the first time, on the first try, and any time you need to go back to it, it is 100% repeatable.
