Maybe a stupid question but I can't figure it out (what's that say about me??)Where do you start the leading edge plywood from? If you start from the bottom of the leading edge=2C how is it held in place while gluing - are nails used? Or do you start it from the top of the leading edge and sand it into the curve of the wing? I just don't see anything in the plans for this. Thanks=2CTom B. ________________________________________________________________________________

Tom basically what I did was sheared sections of 1/16 aircraft ply at about 9.5"when installed flush with the back of the front spar the ply will be just backof the arch of the leading edge profile. I stapled the front section with 1/4"staples at about every inch or less. When glue is dry the staples were removedand the leading edge sanded smooth to blend with the profile. Hope this helpsand is probably better illustrated by the attached photos.--------Adrian MWinnipeg, MBCanadaRead this topic online here:http://forums.matronics.com/viewtopic.p ... ttachments: http://forums.matronics.com//files/dsc0 ... ___Subject: Pietenpol-List: Re: leading edge plywood

The fact of the matter is that all solvent-based products are becoming less andless common all the time, and in the not-too-distant future, legislation willprobably make products like Butyrate dope and Polytone illegal, or at least highlyregulated. Look how much metal gets powder coated these days, compared towet paint. Because of this movement towards low VOC finishes, fabric coveredaircraft builders will all probably eventually be forced to use other methodsthan the "traditional" finishes.There will be those who will say that they will NEVER be able to stop people finishingwith dope, but I remember not so long ago hearing people saying that therewas no way that they would be able to stop people from smoking in publicplaces. It's just a matter of time.Luckily there are some people out there like Stewart's who have developed new low-VOC,water-based products, and some homebuilders that are experimenting withlatex house paint. Before long we'll have sufficient real-world experience tobe able to determine just how well these alternative finishes work on a fabric-coveredaircraft that gets stored in an open hangar (or not), and is exposedto the actual stresses of flight, over the long term.Unfortunately, I don't think it's a question of IF, but rather WHEN the "normal"finish for a fabric covered aircraft will be water-based.I'm a big fan of "traditional" ways, but I also can appreciate newer or even justdifferent technologies that are safer for us to use. Saving a few brain cellssounds like a good idea to me. I know I will need to use some of mine, fromtime to time, so it's probably best to hang on to the ones I have.Bill C.(stepping off the soap box)Read this topic online here:http://forums.matronics.com/viewtopic.p ... ___Subject: Pietenpol-List: Re: leading edge plywood

Thanks for all the replies on the leading edge - I think I can sort it out from what everyone told me.Side note in case anyone cares.... I'm working on the center section after hastily putting it together in July. My mother was dying from cancer at the time and we were going to build the CC together. She ended up getting too weak too quick and I kept pushing to get the CC done while she was still here - just to show her. In my rush=2C I'm paying for some lack of planning now. It's nothing beyond repair but it's gonna be a bit of a pain. My father has offered to help get it completed in honor of my mom.I'm happy to be back in the game making some progress on the Piet. 3 steps forward 2 steps back I guess.Tom B.

nails in the rib gussets are not going anywhere. Maybe there is no "pull" on them. Not sure what it is about leading edge=2C maybe the direction of the vibrations they undergo=2C like the leading edge plywood vibrates up and down vigorously in the slipstream that pulls them out. Remember=2C though=2C Aeronca (and Citibria) have problems with the nails in the aluminum ribs into the spar working out=2C and there is an AD to replace them with ringed-shank nails. I guess the vibration up and down in the rib relative to the spar worked them out. I dont know if ringed nails would stay better in the leading edge=2C but doubt it. I'd stay away from nails if possible.Gene

Just measured mine (I happen to be in the hangar at Smith Mountain Lake thismorning). 2.25=94 between the brake disc and the V block on each side, whichallows room for 3 wraps of =BD=94 bungee (and you might be able to squeeze in afourth wrap).The bungess will wrap the way they want to, and will go side to side ifpossible. If you try to wrap them on top of each other and there is roomfor them to go side to side, they will do so at the first opportunity,releasing most of the tension you so laboriously put in them.Jack PhillipsNX899JP =93Icarus Plummet=94Raleigh, NC _____

It has been on the air since last fall... a pretty good programabout general, commercial and military aviation. They cover a variety ofinteresting topics... this week they were talking about homebuilding and featureda group working on a Piet wing to describe some of the woodworking aspects.Sponsored by EAA, AOPA and others... always a good show.--------Mark ChouinardWings, Center Section and Empannage framed up - Working on FuselageRead this topic online here:http://forums.matronics.com/viewtopic.p ... ___Subject: Pietenpol-List: Re: leading edge plywood

It has nothing to do with reinforcement of the fabric.This is a fast,powerful machine that doesn't have anyissues with getting off the ground. The wing couldbe a piece of flat plywood and it would still fly. ThePiet, on the other hand, needs lift, all it can get.Look at that wing profile in a couple of those pics.It's a round nosed, pointy tailed plank.Bernard even had to undercut the bottom of his to getmore lift.So by smoothing the nose profile as much as possiblea little bit more was gained by not allowing the profileto sink flatter between the ribs.Clif> The Brown B-2 "Miss Los Angeles" flew at over 230 mph with the only > reinforcement to the fabric covering being some false ribs supporting an > extra layer of fabric from the leading edge to the spar.> http://www.flickr.com/photos/sdasmarchi ... otostream/ easier, quicker, and cheaper than fussing with plywood or aluminum leading edges, and lighter to boot.

Don't know about expert=2C but in the case of the Piet=2C the plywood does not add to the stiffness at all. The 1/16 okume ply I used is little better than the cardboard Bernard supposedly used. I did consider just putting an extra layer of fabric around the leading edge and letting the nose scallop like many aircraft do=2C but decided that I would need to add extra nose ribs for it to look right and I did not want the extra weight.Gene> Subject: Pietenpol-List: Re: leading edge plywood

Joe,I built my Piet using the British PFA/LAA approved plans from Jim Wills.They include a fully enclosed leading edge using 1/16th ply.There are some pictures on my web site (http://www.cpc-world.com). Look atPage 9 under "Build Log" -> "Building Photographs".I had some problems bending the ply around the ribs but eventually managedto soak the ply over a small diameter pipe and used cargo straps to hold itin place until the glue dries.I had a ground loop soon after completion of the Piet and the wing hit a 5inch fence post alongside the runway. The ply leading edge broke a little, Ihad to replace one bay, but the fence post sheared out of the ground and wasleft hanging on the fencing wires!The Piet wing with a full ply leading edge is definitely strong!!!Hope that helps.PeterWonthaggi Australiahttp://www.cpc-world.com-----Original Message-----
