I used Heim joints for hinges when I built the new tail on my KR. ?I simply measured and marked the center of the spar (with plywood plates glued onto the spars), then bolted the hinges on with large area washers to help spread the loads on the wood. ?Photos of the spars with hinges is at <http://jscott.comlu.com/KR/tail.html> ?If you look through the photos on that page, you'll note that I also cut the elevator spar in two, so each half of the elevator is removable. ?I'll have the elevator off the plane again sometime in the next few weeks while my KR is going through another metamorphosis. -Jeff Scott Los Alamos, NM > ----- Original Message ----- > From: e.flyer1 at cox.net > Sent: 02/27/13 01:36 PM > To: krnet at mylist.net > Subject: KR> Horizontal Stab hinge alignment > > Is there an alternative method of aligning the hinges before drilling the > spars ? > I have hit a wall looking for 3/16 tool steel longer than 36".
