I have both the cork and the rubber gaskets and at least 2 steel washers. The idea of cutting the gasket is something I never thought about and I like it. I guess I would have to cut one of the steel washers as well. The other could stay in place.
I have a spare ball housing and collar so I could use those as "Polish blueprints". I just do not want to dismantle the unit for as Jerry says, a few drops.
Thanks.
