Hello guys, I see an update is more than overdue, had to go to the fifth page to find the thread again.
Having spent a long time making some as-much-scale-as-seems-possible 45 degree angled fittings I couldnĀ“t wait finishing the 90 degrees ones, and finally had the circle drive tested without them only last week, although I finished the valve already last April. With the glide bearings still missing, the tooth wheels jam in one direction, but funny enough hardly in the other, as you can see in
this video.
