The shaft makes a very good visual impression. The connecting rods are copper-plated, as is otherwise only known from the legendary Hoeckle shafts. The connecting rod bearings are absolutely free of play, the concentricity has a deviation of less than one hundredth, which can be seen as a measurement tolerance, and the offset when measuring the rollover is also barely measurable. The bearing seats at the front and rear are 1-2 hundredths below dimension, which makes it easier to fit the shaft. However, a drop of Loctite should be used to be on the safe side. I noticed the M6 countersunk screws with cross recess, which I replaced with hexagon socket screws with 10.9 strength as a precaution.
