I have a question about the rudder and elevator hinges. I am workingfrom the original plans which call out a fabricated hinge bent andwelded. tried a few and they are really intense. I see by the variousphotos that people are using the AN eyebolts. My AP's only concern isthat if one assy loosens and turns 90 deg , the controls will lock.Is this what they use, and has any problems come up? Whats out thereto choose from?thanks, walt evansI have a question about the rudderand elevatorhinges.

Mike, I too was stubborn and spent quite a bit of time building mine per the plans(after first building a hydraulic bending rig). I was quite proud of my set ofhinges and my interpretation of the (somewhat vague) plans until my AN hardware(clevis pins and pan head screws for hinge attachment) arrived, and I realizedthat, using the dimensions in the plans, I could not install the clevis pins with the hinges attached to the elevator and stabilizer.I've been working on other things until I'm able to muster the gumption to makea set of "taller" hinges. Did you encounter the same interference problem I did? If so, how did you solve it?My toughest challenge the first time around was making a good, but "flat" weldto join each of the hinge pieces. I ended up MIG welding the female hinges, and gas welding the male, just because this seemed to work well for me. Also,I bent each piece and welded them together before trimming to final dimensionswith a band saw. I figured this would keep my out of any trouble with miscalculating setback. All in all, it has been pretty time consuming, but (hopefully) it will be worth the effort to have an authentic Piet.-Bill> > Pasted from Grant's page below. Hope this helps Walt.

I used eyebolts for elevator and rudder hinges. I spent a lot of effort making sure that they wouldn't turn and lock up but, because they don't share the same axis, they cannot turn, and, with three on each panel, they don't lock up.Jim Malley________________________________________________________________________________

Jim,Thanks for your response. Nice to see that you never had a problem withthose hinges.I assume that you are the builder of the infamous Pietenpol that was on thefront of Kitplanes a few years ago. It was after reading your article thatI made the decision to build an Aircamper. ( I still have that issue).Walt Evans-----Original Message-----
