I made a thick cardboard template. First I centered the rudder and cut the template to fit horizontally along the side of the rudder and fuselage for a couple of feet aft of the hinge line. I marked the position of the template on the fuselage and marked the hinge point on the template. Then I cut a 32.5 deg wedge from the template aft of the hinge point. Once the template was taped back on the fuseage the missing wedge area defined the swing arc of the rudder.
I had to reposition the stops vertically because, being a structural engineer, I had aligned the horizontal flange of the stop with the cable figuring that I'd get all the load paths on the cable, rudder horn and stop well aligned. The probelm was that the cable rubbed and fretted on the stop flange on the "slack" side. Some times you can be too clever!
