Re: Pietenpol-List: Jury Strut - flying wing strut attach method

Subject: Re: Pietenpol-List: Jury Strut - flying wing strut attach methodDave,Yes, thats what I did. 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.Lou________________________________________________________________________________
