OK, sooner or later I'll stop asking questions. As soon as I learn everything!
My problem this time is my new diaphragm from the scuba museum. It looks great, fits in the can real well, but I can't get the band around the can after I put the diaphragm in. The ends where the screws go is 1/2 inch or so too short.
What am I doing wrong, and how do I fix it?
