I've been told that is improper to respond to your own post, but if it answers the questions posed
then I feel its OK.
The powder slide cam was installed backwards. The curve of the finger was toward the powder
magazine instead of away. So we now know it can be installed both ways.
I had one press taken apart for cleaning, conditioning. The second press had the slide cam installed
backwards. When I put the press back together I used the other as a model.
Now I know better.
Maybe another new Star owner will remember this and learn from my error.
