Steve,
Sorry to hear about flood. Really hope your plane is ok. I live in
Tennessee and could be there in a day if you need help.

| Subject: | Another British Piet Takes Flight |
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.

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?

Thanks

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.

Hello All,
Are the 1/8 X wires really needed inbetween the wing struts?
Thanks

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.
