Precision reference line
Instead of sneaking up on layout lines as I make crosscuts on my table saw, I added a reference line to my saw’s table that corresponds precisely to the width of the saw blade. This allows me to align my cuts without having to make contact with the blade. To draw the line exactly in line with the blade, I attach an auxiliary fence to the miter gauge and make a shallow cut in its underside. Then I hold a 1/8" paint pen in the kerf and mark the table as I slide the miter gauge away from the blade. I renew the line periodically when it gets too faint.
