Milt, I have built mine in stages like you want to do and have notes from various ordersbut I am sorry I cant determine exactly what I bought for the fuselage. Oneof the best ways to become familiar with the plans and the construction stepsis to sit down with the plans and develop a materials list. When building thelong fuselage youre going to have to work with both the drawings for the longfuselage and the 33 fuselage (for your case dont use the Flying and Gliderplans). Its really rather simple, the wood size comes from the 33 drawings andthe length (for the sides pieces) comes from the Long fuselage plans. The lengthof the wood joining the two sides comes from the 33 drawings as the widthdoes not change. While developing my materials list I have found the drawings are mostly drawn toscale. Find the scale by measuring something in the drawing with a known dimension.If the scale is not a standard scale, I create a scale for that particulardrawing. If you dont know how to do this here is link to a simple techniqueI use. http://www.handprint.com/HP/WCL/construct.html Look for EQUAL DIVISIONS OF A LINEYou can then measure the length of a particular piece and get a reasonable estimateof the length you will need to order.--------Chris TracySacramento, CAWestCoastPiet.comRead this topic online here:http://forums.matronics.com/viewtopic.p ... ___Subject: Pietenpol-List: Are you guys scarfing 1/16th inch plywood?

Hi,Was reading thru EAA's articles on plywood skinning and they mentioned that allthe joints of your plywood for skinning should be scarfed. Makes sense.Have some 1/16th okoume coming from boulter plywood, and being cut in 8 ft stripsthey will need at least one joint.If you guys scarfed them.. how? Thats mighty thin material for doing that.I have a shopsmith that I can angle around as a table saw or setup for disk sandingor maybe drum, but can't image 1/16 material not chipping out something terrible.JimRead this topic online here:http://forums.matronics.com/viewtopic.p ... __________

Make a mark with a pencil tothe thick side of the scarf. With just a little practice you should be able tofeather to the pencil mark.Howdy**************Wondering what's for Dinner Tonight?

Thanks for all the replies.I had researched it a bit, and heard of different ways, it just seemed mighty thinto work with.My okoume plywood came from Boulter a few minutes ago. Bought two 4x8 sheets (cutin to 1x8 strips)so if it works out well I can redo my top wing with it insteadof the .016 aluminum that is wanting to pop off. Or if doesn't go well Ihave enough to get it done even with some miss-steps.Presume you varnish or clear coat, the part of the plywood that will be on theinside of the wing ... before softening the outside with water to get it to bend..then once it is the right shape and dry, you remove the formed piece anddo the glue/T-88 and then once that sets you varnish/epoxy/clear coat the outsidepart of the plywood?JimRead this topic online here:http://forums.matronics.com/viewtopic.p ... __________

I have not been following this thread so someone has probably already postedthis, but take a look at http://home.hiwaay.net/~langford/kspars.html for agood way to do the scarfs. I did an almost identical setup with a piece ofpine shelf board and my Bosch laminate trimmer and it worked great. I onlydid 1/8" plywood, but I have no doubt that 1/16" would work just a good.The entire setup probably took me 45 minutes to make and I can set it backup again when I need it in 10 minutes.It worked best for me with the 1/8" ply if I did the cut in two steps (1/4"pieces clamped against the board the router is on then remove them, don'tadjust the height of the router). Probably would be just fine to run fulldepth on one cut on 1/16".Brian KrautEngineering Alternatives, Inc.www.engalt.com-----Original Message-----

Hello everybody.When I have scarfed thin plywood I make a stack of all the pieces together setting each one back the widith the scarf. I then plan or sand them them all at once. This pretty much ensures the angles will all match when you flip a piece over and glue them together.Steve in Maine> Date: Wed, 14 May 2008 18:17:31 -0400> To: pietenpol-list(at)matronics.com

Subject: Re: Pietenpol-List: Are you guys scarfing 1/16th inch plywood?Guys,I did not scarf any plywood. When I nailed/glued the 1/16 ply to the wing, I only lapped one half of the rib width. Then the next piece lapped the other half of the rib width. Worked like a charm. Just like when you put up a piece of drywall on a stud wall, bearing only half of the 2 x 4.

Thats exactly what I did. Scarfing isn't necessary for the leading edge plywood.Since Bernard originally used cardboard from quaker oats oatmeal tubing, scarfingwould have been a little difficult.Getting ready to go out this morning and help a friend cover his Piet.Rick Schreiber.Valparaiso, IN----- Original Message -----

Grant has (apparently) had some copyright issues in the past with his materials and I would be VERY careful about offering to make DVD's for someone (ESPECIALLY if compensation is involved!)....even if that someone got permission from Grant. I would encourage you to personally get permission (in writing) from Grant before making any DVD for anyone.And getting a copy is DEFINITELY worth the effort! I copied the video onto my iPod and love to watch it from time to time.just my .02 worth...

Glenn (and others),Unfortunately, somehow some rumors got started about Grant. Grant is a great guyto those that got to know him through the Buckeye Pietenpol Association. Hetook over the well established BPA newsletter from Frank Pavliga Sr. He saidhe would do it for 10 years. That's just what he did. I kept myself paid upfor the newsletter and I think there may have been one newsletter at the endthat didn't get printed up for what I paid for. Big deal. He wrote a fantasticnewsletter for 10 years and put loads and loads of time and research intothe Pietenpol stuff. I'm sure few of us would have put the time and effort intoit like he did for the small amount of money taken in through the newslettersubscriptions. He still visits the Brodhead Fly-in every other year or so.I think he just kind of decided it was time to pursue other interests. As forthe copyright on the newsletter and other things, the guy put 10 years of hardwork into all this stuff and did a terrific job on them so I can fully understandhis wanting to protect his work. Unfortunately a few people must havegotten upset by paying their few dollars at the end of his run and didn't gettheir newsletter. They spoke up without realizing his huge commitment over theprevious 10 years. Among many other things he was adamant about the Pietenpolfamily getting credit for what a great design Mr. Pietenpol created. I justwanted to clarify some of this stuff before the mud starts flying because therereally isn't any to throw.I'm stepping off the soap box now!Don EmchNX899DERead this topic online here:http://forums.matronics.com/viewtopic.p ... ______Date: Thu, 15 May 2008 23:24:52 -0400

Just wondering, Jim, what's the big deal about sealing the underside of theply after it's glued in place? You should have plenty of access from theunderside of the wing, since the skin only goes on the top side of theleading edge. Seems a lot easier to work with unfinished plywood, than itwould be to work with varnished ply, especially when it needs to be curved.Bill C. ________________________________________________________________________________

I wouldn't make a big deal of it except I am trying to walk thru how to do theleading edge.This is for a lower wing.. so its different. You can see the plane at www.westcoastpiet.com under photos, under Jim D.The lower wing ribs are squared off. The Pietenpol Aerial plans (Chad Wille's design)shows a shaped piece of wood that is bolted to each of the ribs to forma backing for the wing wrap, and the plans say to use wood for it instead ofaluminum.. but that is it, nothing explicit about how far to wrap it. I presumedthat with the weight of the wrap being so low, it would be best to make a "D"section out of it, which would make getting to the back side of it once itwas glued in place about impossible. With the shaped leading edge support piece in place, even if I didn't wrap it allthe way back to the spar it would still be tight to try to seal it, I wouldthink.This is my first plane.. bound to ask some dumb questions.Seemed like having the spar top and bottom to glue to would make it easier to installthe wrap, and would make it easy to finish, just run a flush router bitalong the spar.JimRead this topic online here:http://forums.matronics.com/viewtopic.p ... ______Date: Fri, 16 May 2008 19:46:25 -0500
