I'm done
All working, and very happy with my results on my first resto.
Mode start update, added a single washer to the underside of the 4 screws of the cup. Removed the back plate and bent it more vertical at the screw point. Then re-positioned it in the vice and rolled it over like a wave shape. Did not add rubber or anything else, and so far so good, 9 out of 10 balls capturing
Here are the pics, unfortunately sun is out in Adelaide but not high enough in the sky yet!
