Up aileron is also in turbulent flow (aft of the separation point on the uppersurface of the wing) causing less of a control force. Greater deflection is therefora desired condition.

An aileronmoves a greater number of degrees upward than downward to counteract adverseyaw. The downward-moving aileron produces both induced and parasite drag, butthe upward-moving aileron produces only parasite drag. To prevent the combineddrag causing the nose of the airplane to start to move toward the down aileron,the up aileron travels a greater distance, producing enough additional parasitedrag to overcome the induced drag caused by the down aileron.

I'm hosting an event I've done in the past primarily oriented towards helping folkswith projects with tools and skills they may not normally have available.I've had folks bring broken machine parts, and we either fix them or fabricatenew.

We could try making hinges... Dynamic balancing, wecould try my IRD Mechanalysis (a notch filter with a strobe setup that's generic,not specialized towards planes and propellers, but will work fine) balancer.We'll be playing with an old saw mill (have a poplar tree you need milledinto a Piet kit?). Some machine tools, lathes, mills, shaper. Plenty of woodworkingmachines. I've got a wing rib jig and can mill up some materials ifyou want to play with that. I do have a couple model a blocks laying around if someone wants to play with one.We could strip the block, evaluate the cylinders, even bore and hone... Could try setting up a line boring jig to machine out the block/caps for inserts.I've got the tools, have never done it... I'll have welders, we've tried gas welding aluminum with mixed results... HopefullyI'll have the TIG welder fixed if you need some stuff welded together, whatever.Lots of woodworking stuff, making and milling wood gear struts is prettyeasy.

Thanks. It's not ALL that expensive. People tend to really kick in and help.We REALLY had fun at the first, the second was much smaller but still TONS offun. Seems the less "organized", the more productive and less stressful, meaning...fun. Otherwise, I didn't collect all this junk (most of it came off a scrap truck) forno reason. No way I'm gonna wear it all out. The main concern is space. In rural Georgia, it's reasonably priced. That hangar, everything you see in the picture of it has set me back about twogrand. Trusses and tin donated from a guy taking down a chicken house. Polesfrom the electric company for free, dimensional lumber from our sawmill and freelogs. About $500 in nails... and more nails... and a decent hammer for myson... hehe. I'm just lucky enough to have a place to put it.So, the philosopy is, if you were gonna pay someone a couple hundred to weld somestuff together, buy gas and come here instead. Lodging is as free as I canmake it, food is no more than anywhere else... you'll make some new friends,likely shoot some machine guns and see and play with some neat other equipment.Also a great venue to get parts moved around. I'll be making a trip from WI downto there before too long, more than willing to pick up Spruce in Madison andget it to GA, come there and get it when you can. Plenty of space to storeit indoors.

Ken,As you said, Uncle Tony has good advice, including what I am about torepeat. I'm glad you took the time to access that information!My cowl came out nice, though I continue to modify it. One of my long termgoals will be to reduce the 5,347 stainless screws, by at least half! Withsome 'noodling' I am, little by little, gathering a plan to use pins (likeMike Cuy, Greg Cardinal and a few others.) instead of some of the screws. Iwill also be able to employ some piano hinges that will eliminate a couplehundred more screws.What I am finding is that removing and replacing the cowl is a dauntingtask, and I'm sure it discourages me from looking into the enginecompartment as often as I would like.Best wishes!Gary BootheNX308MB

The answer to your second question... yes. At a pretty good pace.The first question, the formal addy is 335 Castlerock Ln, Chickamauga GA 30707.Informally, the closest exit off I 75 is Battlefield. The closest exit off I 59is Trenton. Off I 24 is tougher, Broad Street in Chattanooga TN...Basically, there's Chickamauga National Battlefield Park. Downtown Chickamaugais about 3 miles south of that, on Highway 27. Three more miles south of Chickamaugaon Highway 341 is where I live. The intersection of HW 341 and BondsRd. You can only go west. About 1/2 mile from there is a blue street sign forCastlerock Ln. you can only go north. At the end of that, about 1500 feet,is the place. Call from anywhere, we'll dispatch you in, 423 580 1383, or 423 596 7770.Look forward to meeting you!ToolsRead this topic online here:http://forums.matronics.com/viewtopic.p ... ___Subject: Pietenpol-List: Re: Cobra Torches...

THANKS for coming! We actually had a pretty good showing of Pieters whom I thoughtALL integrated well with the old woodworking machines crowd.The weekend (still underway, just had a newcomer show a few minutes ago) was fantasticallyproductive. The Carrollton gang pledged to come early and stay nextyear to help (BADLY needed) mentor the Piet crowd with their projects.Everyone pitched in a lot to keep things moving. However, it was Kellie and Judywho, for no other than reason being saints, brunted the VAST majority of responsibilityfor folks being fed WELL and timely. My philosophy is let grownmen fend for themselves... probably flawed thinking anyway! Thanks to them!Hope to see more folks next year.

A little more progress towards a return to flight. Got the oil screen out, cleaned,and the residue inspected (nothing seemed to be glittering in there). Thanksto Mike Cuy or whoever it was who suggested running the cleaning solventand residue through a coffee filter and then letting it dry to see what's inthere. Works great.Cleaned the carb inlet screen, drained the float bowl (and yes, I lifted the tailto try to get as much as I could out of there). Just looking for crud anywhereI can think of.Re-torqued the prop bolts and safetied them. I think everything is ready to go,firewall forward. Just need to reinstall my centersection flop and the newrear cockpit windscreen, check the brake fluid level in the masters, and I thinkit's ready to fuel up. That will have to wait till next weekend... too busyright now.--------Oscar ZunigaMedford, ORAir Camper NX41CC "Scout"A75 powerRead this topic online here:http://forums.matronics.com/viewtopic.p ... ___Subject: Pietenpol-List: Re: Feb 20 to 24, hangar gathering, doing "stuff", Cha

By the way, and since the list is fairly quiet right now, I'll take a minute topost this. The words "safety wire" should be changed to something else. Everytime I have to safety something, I end up with more cuts than a governmentsequester and "safety wire" is quite unsafe when it comes to its tendency to drawblood. The two worst offenders are the .041 and the .020. The medium-sizedwire is fairly well behaved because you can bend it easily and tease it intoplace with your fingers, but the .041 is a beast to deal with unless you usepliers and the small stuff is like a tiny silver viper, just waiting to get youwith its little fang. And just try working it in a blind area without gettingbitten.The other thing about safety wire is that I waste a lot of it by re-doing the safetying.I can never remember the right way to safety pairs of things and Ihave to start over, or I cut the piece of wire just a little too short and haveto start over. I've also noticed that I get the dirty eye from A&Ps when Iuse any of the smaller sizes of wire. They want everything done in .041 unlessthe hole in the fastener simply will not pass that size of wire, and it's crazy.Why do we even have anything but .041 then? And why try fishing it throughall the little screws and jets and things on a Stromberg carb?My guess is that I could take my big old single-speed Craftsman 1/2" drill andchuck a fly cutter in it, then stake it down with a piece of .041 safety wireand try to bore a hole in some kind of gnarly material with the fly cutter off-axis,and that thing could bite and claw and try to torque itself like a forkin spaghetti and a single strand of .041 could hold it. Why in heaven's namewe need to put that heavy safety wire on little fasteners and turnbuckles I willnever know.--------Oscar ZunigaMedford, ORAir Camper NX41CC "Scout"A75 powerRead this topic online here:http://forums.matronics.com/viewtopic.p ... __________

Oscar,Are you using a safety wire tool to twist the wires, or are you trying to doit by hand? A safety wire tool makes it pretty easy (except forturnbuckles, which are just a pain in the butt).You can get a decent (Chinese) safety wire tool for $20 or less. A good onewill run about $60.Just remember to always put the wire on in such a way that the wire isforced to get tighter for the nut or bolt to loosen.Jack PhillipsNX899JPSmith Mountain Lake, Virginia-----Original Message-----
