    Subject: Cable type/material
    Looking through the archives, I see enough cable posts to confuse me even f urther. From what I gather, SS should only be used-in "static" conditions and galvanized in "dynamic" conditions. 1/8" for the bracing and 3/32" for the controls. My plan is this: - 1/8" SS 7/7 for wing drag cables 3/32" galv. 7/19 for controls - I have not thought through-for the rest of the plane, as I am only workin g on one wing now. However, since I am buying the cable, I might as well ge t what I can for the whole plane. Is there a standard for Pietenpol cable; size, material, strand makeup, and use location? What cable makes the most sense at what locations? I would think that SS would be used outside the pl ane more then galv., but that doesn't seem to be the case.

    Either one is ok, SS or galvanized.- both have been used on certified air planes, SS is the more perfered on newer production aircraft due to its res istance to corrosion.- However using SS for the cabane brace wires has th e bennifit of being non ferrous, and not interfering with your mag compass.

    I agree with Shad. I used Stainless throughout on my Pietenpol. Just make sure it is aircraft grade. Aircraft Grade cable has lubricants added to allow it to flex without chafing that commercial grade cable does not. I used 1 x 19 1/8" stainless for the drag and anti-drag wires, the cabane (roll) wires, and for the undercarriage bracing wires. I used 7 x 19 3/32" for the control cables and the tail brace wires, as well as the flying wires between the lift struts. 1 x 19 is the strongest, but it is a bear to put thimbles on.

    Understood Jack. I was aware of the lube in AC quality cables. A lot of pla ces call their cable AC grade, but it is not lubed. To be clear, 3/32" is a GO for the flying struts?

    We have this exact problem with out Piet. It's quite a challenge. Maybe I'll suck it up and replace the cabane braces with ss.

    Another thing to consider is if you plan to wrap and solder the cable terminals, which is easy, very inexpensive, and more authentic, you might want to use galvanized instead of stainless.

    Subject: mag compass interference
    As I mentioned in an earlier post, my compass swings noticeably when I move the steel tube control stick forward and aft, particularly as the stick goes forward from the neutral position. A hardwood control stick would not introduce this effect. I have never considered the cabane braces to be a factor, assuming that Corky probably swung that error out of the compass when he set up the deviation card. I have never found the mag compass on 41CC to be a problem to use, despite its limitations and mine. Like a Tahitian dancer, it jiggles and sways as we fly along but we always have a general idea of where we're going. When I turn the airplane, the compass does its turn and dip error things and I don't bother with trying to turn to a specific heading because roads and fences are much better for that purpose and they don't jiggle, dip, bob, and overshoot. I have never flown with a GPS or NAV in the airplane and have never been more than slightly lost. 'Course then again, I've never flown the airplane more than about 75 miles in the same direction anyway, so there hasn't been a need to hold any certain heading for more than an hour or so. Looking at the compass in the airplane though, I notice that I should probably refinish the face and service the fluid. Might as well swing the compass again, too, since a number of things have changed on the airplane and the deviation card is all but unreadable. I think I'll try to get a little bit lost again this weekend, if this fog lifts by then.

    From: "Phillips, Jack" <Jack.Phillips@cardinalhealth.com>
    That's why Waco Biplanes used wooden joysticks. It's really not a problem as long as you remember to hold the stick at the "neutral" position while swinging the compass. Anytime the stick is not at neutral in flight, the compass is going to be spinning anyway. By stirring the stick around like I was stirring a pot, I can make my compass do a complete circle. Incidentally, I have compasses in both cockpits and on a long trip I find that I tend to use the one in the front cockpit much more than the one in the rear. I can see it easier without having to duck my head.

    Jack: I am not sure that is "why" Waco used wooden sticks, lots of others did too (Jenny, etc), but just as many did not (Travel Air, etc). It got a friend of mine killed in a Waco when the stick broke off. If the stick is affecting the compass, one could always get it de-magnetized. The effect of something like the roll wires can be adjusted out with the compensators, because they are not moving, as you pointed out, like the stick.

    Jack, you just reminded me that I had thought about putting a "civilian" compass up front for the very reasons you mention. I think I'll see if I can find an old nautical one with brass trim, on a gimbal ;o) Better yet, maybe hung from the underside of the wing centersection. The bigger, the better... I'm getting to be "old weak-eyes". Oscar Zuniga Air Camper NX41CC San Antonio, TX mailto: taildrags@hotmail.com website at http://www.flysquirrel.net

    Subject: Re: Wing tip bow
    My gut feeling would be that , since the further out toward the end of the wing you go, the more subtle things affect the flying, I would assume the tip also "flies". Think that I read somewhere , an article about how the wingtip is alot more than just looking good. What if you build another wingtip and when you test fly it, on a power off stall, it's almost unrecoverable?? Then what do you do? My Piet built to plans stalled wery nicely at 37MPH indicated.

    Subject: Re: Wing tip bow
    The wingtip accounts for a large percentage of the drag of the wing, as the higher pressure air on the bottom tries to get to the top by going around the tip rather than all the way to the trailing edge. Anything you can do to change the shape of the tip to reduce the drag is to your advantage. On a Piet, that may not matter that much because it is such a draggy airplane, but it reduces the effective lifting area around the tip. That is why jets have winglets. They use the airflow coming around the tip across another airfoil (the winglet) to produce additional lift in a forward direction, i.e. additional thrust. Anyway, everything from ath Cub, Piet, etc, which need all the advantage they can get, have shaped wingtips to reduce drag.
