I would definitely do it the "Dr. Dean way", which is to use rod end bearings. They are bomb proof and will last forever. Sure, they cost a few bucks more, and may weigh 2 or 3 more ounces, but I'd take that trade any day over having to rip the stuff off later and cut into them to replace aluminum hinges. Everybody that's done it so far loves it. The poop on rod end bearing hinges is at http://home.hiwaay.net/~langford/dean_hinge/ . I did my hinges almost by the plans (because I couldn't figure out a good way to use rod end bearings) and used oil impregnated bronze bushings. Details on that are in an old KROnline newsletter at http://home.hiwaay.net/~langford/kro12_96.html , about 2/3 of the way down. Wicks sells the exact bushings you'd need for this job. I would really do it with rod end bearings though, trust me on this. You newbies might want to check out all the other good stuff at http://www.krnet.org/kronline/ ...
