Subject: Pietenpol-List: WoodI second Carl Loar's comments on wood from Western Aircraft. If you usesubstitute wood, you must still make sure it is aircraft grade. Thistakes education and time and wasted wood on your part. Or you can turnit over to a professional and use that time to learn welding, fabric, orother necessities of airplane building.

Consider the covering for your fuse as "structural".If you live near the border, see if you can go across today and come backwith Canadian lumber without paying the new tariff. Bush declared anaverage 29% new tariff on Canadian softwood yesterday. I didn't see if thisis effective immediately. If not, I'd buy today and get it across theborder today, otherwise look at the Canadian dollar prices for lumber asmuch closer to US dollar prices.Mike________________________________________________________________________________

I thought Bill Clinton signed a thing called NAFTA which stood for the NorthAmerican Free Trade Agreement. What does a tariff have to do with freetrade? Hello?There goes any chance of expensive Canadian Sitka Spruce for the spars. Nowit is extra expensive.Chris Bobka-----Original Message-----

Dave,I used Yellow Cedar for the wing trailing edges of my Pietenpol becauseof its high resistance to rotting in the presence of moisture. Sinceairplanesin general spend a lot of time just sitting, and the wing trailing edge of ataildragger will be a low point for moisture collection, I figured YellowCedar would be a good choice after being told it was the wood of choicefor pilings immersed in water.After thirty-three years, those trailing edges are still good--althoughthereis a bit of waviness evident when looking down the T.E. At the time I builtmy Pietenpol, there was some concern about getting a good glue joint withY.C. Aerolite glue was used initially and when the wings were stripped forrecover in 1985, some joints had indeed failed. These were re-glued withepoxy and they still seem to be sound. I would suggest making some testjoints with T 88 if you use Y.C.Port Orford cedar was used for the wing spars of a batch of BellancaSkyrocket bushplanes, built around 1945-46 by Northwest Industries inEdmonton, Alberta. It was beautiful stuff and apparently was nice to workwith. If you can find some, it would be an excellent choice for Pietenpolconstruction.I used Douglas Fir and Western Hemlock for my laminated I-beam sparsand Yellow Cedar "swallow tail" fillers at fitting points where bolts passthrough the wood. If Port Orford Cedar had been available, I would haveprefered it instead of fir (or even spruce, which I couldn't find at thetime).Next Saturday (November 15) I hope to fly CF-AUN on the 33rd anniver-sary of its first flight.Cheers,Graham (Camrose, Alberta, Canada)________________________________________________________________________________

I just ordered my plans for my pietenpol. Who do most of you order your wood from?________________________________________________________________________________

I got most of mine from Wicks Aircraft Supply http://www.wicksaircraft.com/, and some from Aircraft Spruce and Specialtyhttp://www.aircraftspruce.com/Jack PhillipsNX899JPRaleigh, NC-----Original Message-----

I got mine from Aircraft Spruce. Aside from one minor, and one not so minor problem,the material is great. For the record (for those that weren't readingthe mail a few months ago), Aircraft Spruce quickly took care of both issues.--------Mark - working on wingsRead this topic online here:http://forums.matronics.com/viewtopic.p ... ______Date: Sat, 06 Mar 2010 18:56:18 -0600

William,Those who have been on this list for a while know that I would be remiss ifI did not point out that you are not locked in to using A/C Spruce. I haveHemlock in my tail, and the rest is Poplar, including the ribs. All wasbought at a local hardwood supplier for under $300.Gary BootheCool, CAPietenpolWW Corvair ConversionTail done, Fuselage on gear18 ribs done-----Original Message-----

I don't have many details really... I just followed the details in Bingelis' bookand adjusted for my spar spacing. The distance between spars is 27 3/4"... my spars are 3/4" thick... that tellsme that I needed to space the arms 28 1/2" apart. The main uprights are 2x4sand the arms are 1x4s (I think), but it really isn't that important, just as longas the material is sturdy enough to support the complete assembly. The armsextend ~5" outward (to support the full width of the spars) and they are supportedby a couple of diagonals, cheap 1/4" plywood gussets, Elmer's wood glueand a few small nails from the nail gun.I used a shim to level the pair and clamped them to my workbench. The rest canbe seen in my log book photos or Tony's book, "Kitplane Construction Techniques."--------Mark - working on wingsRead this topic online here:http://forums.matronics.com/viewtopic.p ... ___Subject: Pietenpol-List: Re: Wood
