Finishing up the work on the clutch bell I added two more posts to contain the moving variator cheek. As someone pointed out previously, if you were to use roller weights instead of the balls, you need to stop the cheek from being able to rotate in the assembly so that it doesn't try to twist and flat spot the rollers. This could either be done by having a cheek with 2 tabs on each side to straddle the posts, or by adding a second post to each side of the bell like I have done.
Like Jbot pointed out, I also needed to cut down the backside of the posts almost flush to clearance the moving parts on the clutch drum.
So far I'm pretty happy with the ceramic balls for weights, but figured I should just do this modification now in case I would like to try rollers in the future.
