Really hope your plane is ok. I live in Tennessee and could be there in a day if you need help. Gene 731-584-3443 ________________________________ Message 2 _____________________________________ Time: 07:36:41 AM PST US Subject: Pietenpol-List: Another British Piet Takes Flight From: "Bill Church" Looks like another Pietenpol showpiece has taken flight in the UK. I was just checking out the UK Pietenpol Club website, and saw this photo. http://www.pietenpolclub.co.uk/gallery/displayimage.php?album=56&pos= 4 Check out the workmanship on this plane - outstanding! For those on the list that put off building because they think they need to have a perfectly equipped shop before they can begin construction, check out this page that shows the progress of this plane six years ago: http://www.pietenpolclub.co.uk/builders/chrisandfransprogress.htm That looks even tighter than Chuck Gantzer's "in-house" building as seen in his DVD. I believe this plane was built by a husband/wife team (Chris and Fran Barley) over a 14 year period... that would make it a lot easier getting spousal approval for having a plane in the house.

The wires also provide a safety factor in case a strut or strut fitting comes loose correct? Rick On 5/10/07, Catdesigns wrote: > > Gus > > Yes, the wires are VERY important.

Chris thank you very much, Do you know how tight they are supposrt to be? I'm thinking then need to be tight. Thanks Catdesigns wrote: Gus Yes, the wires are VERY important. The vertical loads on the wing are supported by the two struts. The struts on a Pietenpol are parallel to each other. This configuration does not resist for and aft loads very well. The wires take the for and aft loads keeping the struts and wing from rotating front and back. They are only loaded in tension so wire works quite well and are lighter then tubing. See attached drawing for a pictorial description. The same explanation works for the cabain struts as well as the wing struts. Some designs, like a cub, angle the rear strut forward to do away with the wires and take the for and aft loads. This requires a very strong fitting where all the wing loads are concentrated. Mr. Pietenpol chose to divide the load into two thus making it safer for the light weight structure to carry the loads.

I'm sorry I do not know how tight as I have yet to finish my plane. Being in tension the wire should not need to be that tight. Just tight enough to take out the stretch. I believe that others have said they should have a dull twang sound when plucked. Not a sharp high tone. Mike Cuy Chuck G. and Jack P. will know better, as they have flying planes.
