looks good fabbr, I can't wait to see that rail in action.
The races in the 930 joints angled from inside to outside, they are straight line though, not curved around a single fixed pivot point. That also contributes to the heat. When a fixed joint is running at a 40 degree angle, the balls are rotating in a circle at 20 degrees to the outer race, 20 degrees to the inner race. In a plunging joint, the ball are traveling in and ellipse. They are close to the center on the front and back of the shaft when the shaft is angled down. They are farther from the shaft at the top and bottom. So the total movement of the balls is greater.
