Leave a little slack. this is to keep a vibrating strut from transferring its movement to the fus. fitting causing possible Work hardening and failure. No problem at the top fitting as the "lolly pop" fitting (as Chuck calls it) can move with the strut. This all if you use BHPs flattened end steel struts as shown on he plans. Leon S.

Cheers, Dave -----Original Message----- From: owner-pietenpol-list-server@matronics.com [mailto:owner-pietenpol-list-server@matronics.com]On Behalf Of PIETLARS29@wmconnect.com Sent: Wednesday, December 20, 2006 4:31 PM Subject: Re: Pietenpol-List: Jury Strut - flying wing strut attach method Hi, I used the Skytek large struts and found it was simple enough to run a # 10 bolt through the strut to hold a stainlrss steel angle to which I bolted the jury strut. I used a very short piece of the 1" aluminum bar stock which matches the internal 'flats' of the the large strut to back the hole site, I drilled a hole through the block and it makes for a solid mount for the strut connection. Looks OK too .

Sorry you won't get to experience this blizzard, I-25 is still closed, drifts in my back yard are over four feet, Lockheed has been shut down for two days. Reminds me of the snow days we used to have back in elementary school in Evergreen.

(GRC-RXD0)[ASRC]" Wow Rick, tha is really something. I heard there were about 4,700 people stuck at the airport in Denver. Glad to hear you've got some Pietenpol working time on your hands---or Christmas preparation time. (Quanza or happy holiday time for you whimps or men with no backbone...of which I hope we have none on the list:) Hard to imagine that kind of weather when at Brodhead a few months ago we were sweating in our tents at 2 AM !

Harvy: "leave a little slack" (words of BHP in the old news letter) applied to the lower end of all 4 lift struts. No problem up top because those"lolly pop" fittings are actually a hinge. I don't recall if the guy he was talking to used jury struts or no jurys. BHP as you know didn't so I'm sure he had vibration even though the streamline tubing he used was formed with the 4 stiffener ribs made into them. None of this may even be a problem with vibration dampening jury struts. It was interesting to look at Alan Rudolphs lift struts at Brodhead. If you get a chance to see these struts check them out. Interesting note on vibration--It's fun to watch the radio antenna on my pickup as I drive. Its made of thin wire and sometimes I see 3 waves of vibration in it as I drive. Dave Abramson--Sorry I couldn't read your question. Yours and many others have started showing up on my screen as dark blue text on a slightly darker blue back ground. Maybe Santa will bring me a new computer and a Hooters babe to show to use it. Rick--Your winter pictures kind of make us long for those mild Ohio winters don't it.

The airport may not open again till tomorrow now. They even had to cancel the Avalanche-Calgary hockey game tonight, that's the worst part of it. Imagine spending two or three days with the wife and a few young kids at DIA waiting for a flight out to the mid west for Christmas, which happens to be where this storm is currently headed (you guys keep your snow shovels handy). Glad I ain't going no place. And yes, now that I have the driveway plowed (only took two hours) I believe I will retire to the garage and get some work done on the wing struts Jack sold me. Merry Christmas (an extremely white Christmas in my case). Rick On 12/21/06, Cuy, Michael D. (GRC-RXD0)[ASRC] wrote: > > Wow Rick, tha is really something.

Breathing a sigh of relief that the blizzard in Colorado is going north east to Neb. rather than east to Ks. Leon, I've never heard that one from B.H.P. !! I don't think it would be much of a problem if lift struts are installed. Work hardening is much more prone to Aluminum...another reason to stick with the steel struts. I don't like the idea of leaving those lower strut bolts a little loose...I think it would wallow out the bolt holes. That is some kinda storm, huh ??!! I just heard that Interstate 70 is still closed down from yesterday !! Merry Christmas to all !! Chuck G.

It worked out nicely because the strut length is 10 feet; I bought 4 and carlson, (Skytek) cut them into 8', 2'' sections which stowed nicely in my van. I had asked them for the specs and the details of their strut design for one of their own aircraft designs and also bought some 1" square bar stock which mates with the internal flats of the strut and fabricated the end attachments out of the bar stock per the detail drawing. I lengthened the cabanes about 2" so it all worked out nicely.
