Walt,Read your messages last week on the Piet netabout hinges. I've seen some before on Pietswhere the builder took pieces of square orrectangular tubing ( I assumed it was aluminum )and made hinges from these. They used two differentsizes that would nestle inside each other. Wish I could draw a diagram on this thing to explainit better, but if you use your imagination I thinkyou can figure it out. They cut away the top part of the tubing to make the hinges. I am going to try it. I ordered two pieces ofC-channel from Wicks. It should arrive tomorrow--so I am not speaking from a successful experience,just what I intend to try. One piece is 1.25" O.D.with 1/8" wall and the other is 1" O.D., also with 1/8" wall. (Aluminum--6061-T6, I think) I'll let you know my impressions as soon as I get achance to play with it.

John, Couldn't you do the same thing using the same size channels? One edgewould lap over inside and the other outside. By flipping one hinge theendplay would be taken care of, maintaining position of the control surface.J Mc-----Original Message-----

John Do you think 4130 chrome moly steel would be a better choice than6061 T6 aluminium for the hinges? Thats what i'm going to use on my Piet.-----Original Message-----

Sam,Jan,John:I'm making aluminum hinges from 1-3/4 x 3/4 6061T6 and using the overlap method. The only difference is that I am making them and sending them to a plating shop to be HARD anodized which puts a very hard wear surface all over. My concern was with the bearing strength of the holes. My tail section is almost done, so I can check the viability of this installation soon. My shop is slow, so I'm making a whole bunch of these. The min. charge for anodizing is $125 so I need to send a lot of them. I am currently drawing all of the metal parts in AutoCad and making the attach fitting ends 1/2" per Mike Cuys video. I'll check the results with my own installation.Doug Sheets>From: John Fay >Reply-To: Pietenpol Discussion >To: Pietenpol Discussion >Subject: Re: Rudder and elevator hinges>Date: Thu, 22 Apr 1999 19:33:15 -0700 (PDT)>>>--- SAM & JAN MARINUCCI wrote:>> John>> Do you think 4130 chrome moly steel would be>> a better choice than>> 6061 T6 aluminium for the hinges?
