I don't mean to buy, I know Linegear has them and you can find OEM around. I mean when you drop them, especially in carpet! I was missing a gasket for a long time, and when I sent my frames off to The X-MAN he included one for me in the package back. Just went to put my newly refinished/tighted Juliets back together with my old lenses (new ones havent arrived yet) and promptly dropped one of the gaskets again. Arrrggggghhhhhh. I ordered a few more from Linegear along with a full set of violet rubber for my XS but until that arrives I'm a gasket short again. Also how much pressure should you need to apply to an orb screw to get it to "bite"? Without gaskets mine grab just fine, but with a gasket I just cannot get it to bite - it's almost like the screw is slightly too short (since it works without gaskets). Any tips?
