Pietenpol-List: t-nuts vs anchor nuts

Im favoring the capstrip idea. I would just cut the spar a little short (thatwould allow me to slide it in without cutting anything else) and then slidinga piece of capstrip the full length. It would be glued and nailed in place.--------John FrancisRead this topic online here:http://forums.matronics.com/viewtopic.p ... ttachments: http://forums.matronics.com//files/dsc0 ... ___Subject: Pietenpol-List: t-nuts vs anchor nuts

For the ailerons is anyone using t-nuts over the standard anchor nuts? The biggestdifference I find is price. t-nuts .29 each vs. anchor nuts (with plasticinsert) 3.30 each. Perhaps I could go with anchor nuts (which my technical advisoris telling me to do) without the plastic inserts. If so, do you use loctiteto hold the screws in?--------John FrancisRead this topic online here:http://forums.matronics.com/viewtopic.p ... ______Date: Tue, 5 Jun 2012 09:15:08 -0700 (PDT)

I'm not at that point yet, so I couldn't say for for sure how I will do mine, BUTif your technical advisor says to use anchor nuts or nut plates, then I would.There is no way to saftey a tee nut, unless you used lock tight. These nut plates are all metal and not too expensive:http://www.aircraftspruce.com/catalog/h ... ts4.phpand if you look at this doc:http://www.coastfab.com/images/pdf/2010 ... 61.pdfThey self lock due to the fact that the hole is a little out of round. If all else fails, this is actual AN hardware, not true value hardware.Read this topic online here:http://forums.matronics.com/viewtopic.p ... ______Date: Tue, 5 Jun 2012 10:52:08 -0700 (PDT)

The plans seem to show cable guides just outboard of the pulley going to the stick and another in the area where the strut joins the spar. Are just these two required or have people included more guides along the distance?Ralph in South Dakota________________________________________________________________________________Subject: Pietenpol-List: Re: NX510JD IS FLIGHT READY

What spacing did you use with the T nuts/screws on the ailerons? When using the piano MS--- type hinges on an aluminum plane, we put one rivet at each hinge extension (the attach point). I am using the 1" wide MS --- aluminum piano hinges and have installed 8-24 screws and the self locking nut plates at every 3rd hinge extension. This does not seem as good as, or as stable, as having an anchor at each hinge extension. Placing the nut plate/screws any closer together may create a "fault line", or weak point, along the aileron beams (spars).Also, the self locking (slightly ovaled) nut plates work very well with bolts with hex heads. But TOO well with Phillip head screws. The nut plates are so tight they cause the heads to strip out before the screw can be secured. I have opened the nut plates with an 8-24 tap before installation so the oval is not so severe. I will use loctite when I make the final installation.Suggestions would help.Thanks in advance.....Ray KrauseBuilding the Sky Scout. ----- Original Message -----

RayMine are on 7 to 8 inch centers. Not flight tested but I have tugged on theaileron and have not noticed any problem. I was more worried about making aweak spot along the aileron spar if I put them closer. If you look at mikeCuy's aileron hinges his are spread apart too. Remember the flight speedbetween the aluminum plane and the Pietenpol is way different. On a fasterplane I would want them closer.ChrisSacramento, CaWestcoastpiet.com _____

Mine are on 2" centers, and I also used # 8 MS24693 screws to attach intonutplates. I did exactly the same as Ray - used a tap to partially open theself-locking feature, otherwise the heads would strip before I got thescrews all the way in. No problems yet, with 260 hours and 7 years on them.I do inspect the screws on each preflight inspection - easy to do, just liftthe aileron and look to see that all screws are flush. Takes about 2seconds per side.Jack PhillipsNX899JPSmith Mountain Lake, Virginia _____

Thanks to Chris and all the others who responded to my question.It is hard to remember that the Sky Scout will not be the same as the Waiex in speed and performance! My spacing measures about 3 inches, so I should be OK. I have epoxied in the anchor nuts and will go back and maybe apply the plywood covers to be sure. Sure don't want the nuts to come loose in there!I agree, it will be easy to check before each flight to see if the ailerons are still attached well.Thanks again for the speedy response.Sure missed you at Fraiser Lake, Chris.Ray Krause ----- Original Message -----

You know=2C even without any provisions to prevent loosening=2C the aileron hinges have a screw every say 6"=2C so there are something like ten in each aileron. The screws are about an inch and a quarter=2C or half. How in the world could enough of the ten back out far enough to do any harm at all without you noticing it? Carry a screwdriver=2C put a drop of glue of some kind=2C or even locktite on the screws=2C and don't worry about it. 8)

Jerry=3BYou will get varying advice=2C but for first flights mine is: lift it off at 50-55 or so. Climb out at 65 so the controls are responsive and you don't mush. Fly your pattern at 65. Hold final at 65 till you're on short final=2C calm air=2C then let it bleed to 55 as you come over the threshold. If there is a cross-wind=2C you are on your own! Taildragger pilot=2C do what you know how to do with these airplanes because this one is a stick and rudder airplane and it likes to come down when the power comes off.Over the numbers=2C if you have the nerve to look at the airspeed indicator=2C let 55 bleed on down to 45 when the lift will be all gone and you'd better be able to reach out from the cockpit and touch the numbers painted on the runway because... any slower than that... you'll be squeaking the tires on the ground. And if you don't=2C get ready for a bounce!The ASI is all but useless beginning from when you're over the numbers=2C so don't bother looking at it. You fly this airplane by feel and by sound and by peripheral vision when you're down by the numbers. This airplane is always instructing and it doesn't care about you as a pilot at all. It's going to fly like a stick and rudder airplane no matter what you do! If you're a good taildragger pilot=2C you and the Piet will quickly be great friends. If you're not a good taildragger pilot=2C you'll soon learn and THEN you'll be great friends! This airplane is so much fun to fly.Oscar ZunigaAir Camper NX41CC "Scout"Flying Squirrel N2069Z "Rocket"Medford=2C ORwebsite at http://www.flysquirrel.net ________________________________________________________________________________Date: Thu, 7 Jun 2012 04:59:32 -0500Subject: Re: Pietenpol-List: Re: t-nuts vs anchor nuts

Thanks Oscar. I will respect her. Way back when I flew the Stearman so much I hardlyever looked at the airspeed. I could tell from the song of the wires howit was doing. I sure appreciate the advice.

Pietenpol-List: Re: tire pressure on motorcycle wheeled Piets

Post by matronics »

Original Posted By: "bender"
Subject: Pietenpol-List: tire pressure on motorcycle wheeled PietsIs that a good-looking Pietenpol of Jerry's or what? That's going to get up and climb with that big engine.One thing that crossed my mind due to recent experience is adjusting tire pressure to get grandma's featherbed just right. Or is that Goldilocks? Never no mind, but a few pounds too much tire pressure in our motorcycletires can make the plane bounce pretty good on landing-especially if your bungees don't have much give.I like to keep my bungee cords pretty tight so I have aileron authority in crosswinds. If the bungees are too looseyou can actually have a strong crosswind get under one wing instead of being able to dig into it. Enough about that.I've found that 18 to 20 psi in the motorcycle wheels works well on pavement. Your mileage may vary.The plus side to higher tire pressures is that your takeoff roll will be faster. You play with the pressures and find outwhat works best for your suspension and runway environment. This all makes me want to go fly. Think I'll burnsome hydrocarbons soon.Mike C.[cid:image001.png(at)01CD448E.18CD1270]________________________________________________________________________________Subject: Pietenpol-List: Re: tire pressure on motorcycle wheeled Piets

Gene=2C I also used T-nuts. I had some #4X1/2-inch sheet metal screws on hand so I drilled a small pilot hole beside each t-nut on each side and ran a screw into each so that the heads of the screws overlapped the flange of the T-nut. Those screws prevent the t-nut from coming out when the #10 flat-head screw goes in. Just wonder if I should use Loc-titeon the threads of the flat-head screws. I'm planning to do that -- just looking for confirmation that it's necessary. Chuck ----- Original Message -----
