Thanks guys--EvH, JG, and the rest. To put the matter to bed with the intent to inspire others to jump on some repair job you're afraid of, put it in atother perspective. On this one, what did I have to lose? A 250 or 350 dollar lens if I fouled it up? Think about something else. Like a Cancer Center of America commercial. In that light, a botched-up lens job still has me being a lot better off than THOSE people. So get out your tools and your guts, use some sense, refuse to be beaten, and it'll work out. There's no excuse for knucklehead-boob work.
