I'd have to count them and some of them are buried inside the fuselage or wing now due to painting. To get an accurate count, I'd have to go through the plans and figure it out just as you will. Basically it is pretty easy. You need one turnbuckle for every piece of cable on the airplane. The size can be determined by the cable size. AS&S lists in their catalog the breaking strength of the turnbuckles and the cables. SIze your turnbuckle so it is at least as strong as the cable it is adjusting.

Rick H As others have said, since nearly every Piet is slightly different, no list exists. I found it best ot buy the hardware for whatever section I was working on at the time, planning it out ahead of time by looking at the plans. I did order one of Aircraft Spruce's hardware kits with assorted sizes of AN hardware and found that helpful. For turnbuckles, I counted them up ahead of time so I could buy them cheaply at Oshkosh from B&B Aircraft supply (about half what AS&S charges). Turnbuckles are the single most expensive hardware items. ________________________________ Message 2 _____________________________________ Time: 08:30:17 AM PST US From: Michael D Cuy Subject: Re: Pietenpol-List: 75th Pietenpol Anniversary --> Pietenpol-List message posted by: Michael D Cuy Larry-- are you going to Champaign/Urbana for the SAA fly-in ? I am still 'up in the air' about going to that one. Wouldn't be that long of a trip. Would you camp or motel it ? You know if Kinsella is going ?

And how much should I expect it to cost if I pay someone to take one that's run out and rebuild it?

Hey guys--- Just found this in my list of chicken-scratch drawings and thought if it might help any of you to see it. I don't think the image size is too big so I decided to attach it.

I need to mount a step somewhere near the front of my fuse so I can get up to the center section tank in case (well, ok, WHEN) there's not a ladder handy..... So I'm thinking about mounting a length of round 5/8"-.095Wall Thickness (WT) 4130 tubing inside a piece of 3/4"-.058WT tubing so that it can telescope out around 6" or so......and that will be my step..... I have no idea even what range of sizes to plan for without doing some tests, a VERY expensive process when using 4130...... Any estimates on what kind of load this setup would handle? Or what other combinations might come close to handling 200lbs plus a fuel can (maybe an additional 40lbs)? jm ________________________________ Message 6 _____________________________________ Time: 04:26:57 PM PST US From: "Hubbard, Eugene" " types? Subject: RE: Pietenpol-List: How about some help from one of you "engineer " types? The way I see it, you have 200 lb on the 6" side of a lever giving 2400 lb on the 1/2" side of the same lever (well, 5/8", but 1/2" is easier to calculate). The top half of the tube will be in tension, and to the extent that pi=3, you have about 0.2" sq inches of cross section (3 x 5/8 x .095). Total tension on the 4130 is 12,000psi. Since 4130 is good for 50,000 psi or so, you should have a safety factor of about 4. Seems OK to me. Make sure that you have enough of a lever arm on the inside that you don't overstress the wood where you anchor the 3/4" tube--spruce is only good for about 900 psi across the grain (as I remember).
