Just another tip I forgot to mention.  The manual recommends a 1/4" rod to center the hinges.  This is fairly flexible, and leaves too wide a margin in my opinion.  If you don't install the bushings until after bonding, you can use 3/8" rod or 5/16" (if you account for the spacing).  Use a threaded rod with nuts and washers top and bottom for each hinge, this guarentees (sp) a 90 degree angle (on the hinge line, not 90 degrees to the spar).  You can then install the bushings with a C clamp.  Check fit them before hand, since part A and part B may not fit.

BTW:  the manual also shows bushings for the -3 bolts attaching the rudder cable to the T hinge.  I don't have bushings for that, and the hole is sized for -3 already???  I think no bushing?
