ok, obsessive yes, compulsive no. i am sure i am not alone in having collected tools for 40+ years. after building motorcycles, cars, guns, etc; doing my own carpentry, plumbing and electrical work, i'd say i have a few tools around here.
a couple of months ago i misplaced a brand new carbide end mill, which i used extensively for removing Springfield XD front sights -- the factory installs these sights with a hydraulic press, and while i have the ability to 'unhydraulic' something, the slide is machined with an offset that requires a milled and stepped jig to hold it for un-hydraulicing. i have not had the time to make one, so i usually just cut the sight off.
i went crazy for a week looking for the damn thing, and it was sitting literally right in front of me all the time.
during a competition last week, i was running arround with my mag holder in my left hand asking everyone on my squad if they had seen my mag holder.
fortunately, my friends are kind to me about this sort of stuff. so is my wife...
