BUT...How are you attaching the strut ends? Hmmmm? With bolts drilled through holes in the tube. Right? Yes. So, what's the difference between holes near the ends and a hole in the middle? Just location for the purpose of changing one long column into two short ones. Oh, and just for the record I'm not advocating that hole be in the exact center. As noted a number of times this connection must be made off center to limit destructive harmonic vibration. Clif Interesting, I have seen several Piets with jury struts bolted through the flying struts but I didn't have the nerve to drill holes in mine (doesn't mean that there is any problem doing it that way). rh I was very surprised to see that the kit uses 2, 3/16" bolts through each wing strut for the jury attachment with an insert to prevent crushing.

Jack, Marci and I plan to be there and enjoy your hospitality. Thank you! Gene, I faced the same issue when I changed my Ford for the C-90. I really wanted to keep the nose as short as possible, so my answer was to make my engine as heavy as possible. I left on the old heavy starter, heavy generator and mounted the batt up on the engine mount and didn't worry about saving weight (obviously) on the cowling. I used Don Emch's mount jig and the CG ended up just right. The nose is maybe an inch longer than my ford installation was and I believe I had shoved the Ford forward three inches.

(GRC-LME0)[Vantage Partners, LLC]" Subject: Pietenpol-List: Riblett vs. Pietenpol wing cabane strut length: the math has already been done for you For those of you who missed this excellent post (and calculation---thank yo u Bill!) from Bill Church on July 4th it might be of possible interest for those using the Riblett airfoil. Mike C. There was a discussion about wing incidence about three years ago, and at t hat time I created a couple of drawings to illustrate the relationship betw een the cabane strut lengths, and also between the chord line vs the bottom of the spars. They are attached again to this posting. For the "to the plans" Pietenpol, the 1" difference in cabane struts create s a 2 degree angle. Added to this is a 1 1/2 degree angle formed between t he chord line and the bottoms of the spars (since that's where the cabanes attach). So the effective angle of incidence between the airfoil chord and the top longeron is 3.5 degrees. For the Riblett 612 airfoil, there is a 2.1 degree angle between the chord line and the bottoms of the spars. So, if a Riblett 612 airfoil is mounted on "stock" cabanes (front 1" longer than rear), the effective AofI would be 4.1 degrees. If the front and rear cabanes are made equal lengths, with the Riblett, the effective angle would be reduced to only 2.1 degrees - almost 1 1/2 degre es less than the "to the plans" Piet. In order to produce the same 3.5 degree angle, but using the Riblett 612, t here should be a difference of approximately 11/16" difference in cabane le ngths (front vs back). Food for thought.

The angle between the lift struts and the wing is about 30 degrees. sine theta=opposite/hypotenuse. An increase of 1/2" in the "opposite" direction will increase the length of the hypotenuse by 1 inch. Do you really have an inch of adjustment in your lift strut forks? (honest question - I never needed to adjust the forks on N8031 when I owned it). What about the turnbuckles attaching your aileron cables? Can you increase those a 1/2"? Let us know how it works out.

I never said don't do it Mike. I did say holes are already being drilled and from a tensile strength standpoint this is just one more. Since you are capturing that long tube near the middle, no matter what method you use, you are creating two short tubes. You could actually cut the tube in two, connect those together again with bolted fittings, tie in the jury strut and have the same thing, only heavier. The whole reason for doing the jury strut thing is to create significantly greater resistance to bending under compression loads, like hard landings and strong, sudden downdrafts. Each of those shorter tubes has much, much greater resistance to bending under load. If there was only tension load and never any compression loads, bending would not be an issue. In fact these massive struts would be redundant. Wire cables would work just fine. Look at your average sailboat.
