I guess I am one of the oldest users of the Board Buddies around. I originally mounted them on my old Makita 10" table saw over 20 years ago. As for the installation instructions they were pretty vague and apparently still are. I had to drill holes in the fence and add wood to make the fence thick enough for the installation. Even though the installation is a pain in the ass the safety factor makes them a great investment. I have really pushed the old saw beyond it's intended use and never worried about kickback. They're that good. When adjusted properly the boards being cut simply are held against the table as the wheels rotate and guide the wood in the outward direction eliminating kickback. I will be moving my original pair to my newer Porter Cable table saw.
