Dear Nandric,The first was the recommendation to use Bearwald instead of Stevenson and consisted in increas of the spindle-pivot distance with 1,5 mm (aka eff.lenght of 246mm).
When I adjust the PS distance at 231,5 mm, my SPU can not catch the Baerwald - it is on the Stevenson point. I need 1,5 mm to catch the Baerwald (Dr. Feickert protractor) or the Dennesen protractor intersection point.
When I adjust the SP distance at 230 mm, the SPU is just on the Baerwald and on the Dennesen points ....?
