On the shell plate, at each station there is a little brass pin that keeps the case in the carrier plate. They work well.
My shop vac ate one of them..didn't even chew it, just swallowed it. Rats!!
Fortunately, it was a new bag in the vac, and just a small incision in it, and I found the pin.
So, I learned that my usual proceedure of using canned air pressure to clean crumbs off the press, THEN vacuum the floor is a better proceedure.
Learning experience.
