Sounds like a great help. Don Cooley ________________________________ Message 2 _____________________________________ Time: 05:01:42 PM PST US From: Richard Schreiber Subject: Pietenpol-List: Turtle Deck Stringers --> Pietenpol-List message posted by: Richard Schreiber I have been trying to figure out the location of the turtle deck stringers, but it has me stumped. Should each of the stringers be perfectly straight form the front arch support aft of the rear seat to the horizontal stabilizer, or do they take on more of a curve as they get closer to the top fuselage longerons? I started out by constructing the front arch support and locating each of the stringer slots equidistant around the support. Using a string from the top of the front arch support to the horizontal stab, I determined the proper height and width of each of the remaining two turtle deck arch supports. I then constructed blank arch supports and placed them in the proper location. Using a chalk line I then determined the location of each of the stingers (I am using 9 insted of 7). Using this method the stringers are straight, but they are not spaced evenly around the arch support. I tried it again this time using dummy arch supports made of 1/8 plastic sheet. I spaced the stringers evenly around the arch, with the slot for the stringers cut on the radius of the arch. Doing it this way the stringers are evenly spaced, but they take on more of a bowed appearance as they get closer to the fuselage side. What is the correct spacing?

Unless the top longerons are EXACTLY straight from the front support to the rear support, then the stringers HAVE to be bowed. Now maybe the top one(s) can be straight but the ones closest to the top longerons will most likely be bowed some or even quite a bit.....

It's the straight line of the stringer that will show though the fabric. Check out http://www.cpc-world.com for more info.

The original plans called for those arches with notches in them, then I saw the ones that made the "broom". I opted for the broom, with each piece of a support a separate "stick" with a notch. With lots of sticks, and lots of clamps, you can support the stringers from front to back thru two stations by sighting along the stringers and adjusting the broom pieces till all is good. Then I marked each piece and outlined it with pencil, so i could be glued correctly. They say the judges at Oshkosh sight down the stringers for the "big prize" : ) walt evans NX140DL ----- Original Message ----- From: "Richard Schreiber" Subject: Pietenpol-List: Turtle Deck Stringers > --> Pietenpol-List message posted by: Richard Schreiber > > I have been trying to figure out the location of the turtle deck > stringers, but it has me stumped.
