I know, lots of detail questions....here's another:
The Zoomatic strainer is mounted with two screws and a larger threaded piece with a nut on it. Mine uses about five washers, which looks kind of strange for a factory mount. I know it is connected somehow to the tension adjustment knob, but I am trying to make the drum as correct as possible.
Any photos of the inside of the shell where the strainer mounts would be really helpful.
The Slingerland book does not show this kind of detail (in case you were going to suggest) :)
