I'm having difficulty setting the sliding table fence to 90° using the cam-adjusted stop attached to the side of the table. The instructions say to loosen the set screw and rotate the cam until 90° is attained. This method is tedious and imprecise. When I finally got the cam to where I thought it needed to be, tightening the set screw forces the cam to rotate out of adjustment. I found myself just tightening the cam and using a rubber dead hammer and a punch to tap the cam into position, which becomes another tedious trial and error exercise.
I'm curious how other K3 owners are squaring up their slider fences.
