53 Sylvania up & running

The focus screws should turn very easily. They seem to only have much of an effect when the gap starts to close. Once they get about 1/4" - 1/2" away from the other pole they don't seem to change the focus much.

I don't know about the centering screw since mine is different. I would doubt that the wing nuts need to be loosened.
