I want to modify my ATF55 to add a zero-clearance splinter guard on the right side. I am thinking of securing an aluminium extrusion using the two lower guard cover screws and affixing a piece of 1/4" polycarbonate to act as a zero-clearance splinter guard. Has anyone done anything similar? Any other ideas? Wish Festool would come out with a retrofit part along the lines available for their new plunge saw.
