After completing the bevel on your new custom-length fence, run a pencil along the backside of the guide rail to mark a line on the fence. Next, lift the rail off the fence and use a bright-green marker to the right of the pencil line. Now, the next time you set you fence simply make sure you can not see that bright-green mark.
I like this idea, but got to thinking and realized this will not always work. If you deliberately calibrate your fence, let's call it, "setback" it will only work for one particular thickness of material. As you raise the rail higher to cut thicker material, the point that the blade contacts the surface of the MFT keeps reaching farther into your setback. In other words suppose I calibrate my setback with my rail height for cutting half inch material. The blade will reach back approximately half inch with a cut at 45 degrees. Following the same procedure to cut say 1 1/2" thick material, now my blade is reaching back 1 1/2". Therefore, you have to adjust your setback to 1 1/2+ to clear the saw blade.
That being said, the most setback one would have would be the max thickness cut at an angle of 45 or greater. Once that is established you can calibrate your fence to that and have no worries for all other cuts. For those that have the TS55 AND the TS75 you would have to use the TS75 to calibrate to be safe.
Does this make sense to yall? Please chime in if you think otherwise because I think I will make this into a another Festool mod for my MFT.
