I'm going to clean and lube the helical. This lens is a double whammy unit with multiple start threads on both sides of the helicoid. Does anyone have a foolproof or at least logical method of getting it back together right? There's four threads on each side of the helical so I figure there's at least 15 ways to do it wrong. Thanks. Bill
