We are building an air camper with a three piece wing. according to the plans, there is a 2-3/8" gap between the wing panel butt rib and the center section butt rib. Since this is the separation point between the two panels, what is done with this gap when covering the wing? We don't see any way of supporting the covering at the butt end of the center section.Thanks,Jim BirkeIra G.

I've been welding for 30 years in various capacities, and probably weldevery other day in my sculpting studio. Learned on Oxyacetylene, thenlearned stick, mig and tig. I'm not expert welder, but I've worked withthem all.MIG welding, commonly called "wire feed" is one of the most common weldingmethods out there because it's real fast. It is however, not recommendedfor airplane construction as it is difficult to control the quality of theweld and penetration to the degree required. I'm sure a top welder couldproduce a serviceable aircraft structure, but it's tricky for most guys.Stick welding is not for airplanes.Gas welding or Oxyacetylene welding uses two tanks of gas, oxygen andacetylene to produce an actual flame which is used to do the welding. Ithas been used forever on aircraft and can produce great welds. More heat isgenerated over a larger area than the electric welding methods, which cancause problems, but can also be used to straighten things. A gas rig ischeaper than most tig rigs.Tig welding to me, really feels a lot like gas welding as you're holding thetorch in one hand, and the filler rod in the other. Tig to me is the way togo, though the machines are expensive. They easily weld steel, stainlessand aluminum, and lots of other metals. I much prefer tig welding, and as stated earlier by others, is now thestandard aircraft welding method worldwide. I find it requires about thesame amount of technique as gas, is cleaner and faster and very, very handyaround the shop. I also have a gas rig though for other jobs like brazing,silver soldering, stress relieving and removing warps.Douwe________________________________________________________________________________

Hi Jim,I used a 4" wide strip of .025" thick 2024-T3 aluminum to cover the gap. Idrilled #10 holes about 4" apart and screwed the fairings directly to theribs of the wing root and centersection butt with # 10 sheet metal screws.The fairings are each one piece, starting at the trailing edge, wrappingaround the leading edge and back to the trailing edge. As you can see inthe picture below, I started by screwing the bottom of the trailing edge tothe ribs, then wrapped around the leaading edge and put tension on the stripwith a weight (the cinder block you see hanging from the strip) to hold ittight while I got all the screw holes done. Once the holes were positioned,I trimmed the trailing edge and tucked it under the fairing on the bottom ofthe wing so there was not an edge exposed to the slipstream. They haveworked just fine for 5 years and over 200 hours of flying.Good luck!Jack PhillipsNX899JP "Icarus Plummet"Raleigh, NC _____

Hi Dave,I used the Stewart System, and would highly recommend it. It is heavenly just to walk over to your utility sink and clean up with only hot water. Think of how many times you would typically need to spray solvent through gun parts etc. YUK! The SS glue is great stuff to work with. One thing though, the room temperature needs to be warm (70+) otherwise you will be frustrated with the pace. Initially tried to start in by cold basement and gave up. The glue depends on evaporation. I am now in the process of hand-painting my logo on the side of the fuze. I had a fuel leak previously and dribbles of gasoline were slowly making their run down my fuselage finished paint job. When I discovered it I set to work at stain removal with Dirtex (common store-bought cleaner). I was very worried, as I continued to rub and rub pretty hard to get it clean. I am very impressed at how the SS paint holds up to that type of punishment. Also, if your final color coat will be a light color (white, yellow etc.) the underlying primer must be white, with VERY LITTLE of the "silver" showing through. The color coats are great, but thin, and do not cover dark underlying spots very well. Also, the Stewarts are very good at tech support and call back without fail.Dan HelsperPoplar Grove, IL.-----Original Message-----

Tom,It's tough to beat the advantages of a terneplate or aluminum tank. I supposeyou could make an aluminum panel to screw down on top of the fiberglass tank.Or you could make a new tank out of aluminum or terneplate.

How about another couple of options:1) make a sheet of aluminum to cover the tank, rather than fabric. Easy toget to the tank that way if you have problemsOr, 2) make thin rib caps out of aluminum channel that can ride over thetank and rib stitch it to them. That is what I did, but I wish I had doneoption 1) above.Jack PhillipsNX899JPSmith Mountain Lake _____

Tom,I glued a piece of wood cap strip to the top of my aluminum tank, right down the centerline, and then fabricated a removable aluminum access panel, held on simply with sheet metal screws into the wood (adjacent rib caps). So far I have removed my leaky tank twice. So glad I didn't bury it. I probably need to make a new tank. I have discovered after observing other production tanks, that my design is not the best. Mine is prone to cracking at the seams because I failed to stiffen the adjacent area with "dips" or corrugations. At Oshkosh, there is the Aeromart, which is basically a big tent flea market of everybody's unwanted aircraft parts. I paid special attention this year to the aluminum tank designs. Got some good ideas.BTW the first morning (Tuesday) at the OSH Aeromart is kind of like a Black Friday early a.m. line in front of WalMart. The true die-hards are all there standing in line about two hours before the opening. It is quite fun, and I participated this year despite having nothing on my agenda to buy. I would highly recommend it to any active Piet builder. There are many "treasures" to be had there every year. The year that Santiago (from Argentina) was here, we had such a good time, trying to fulfill his wish list. The best strategy I have found is that when you spot anything of possible interest, grab it, placing it strategically under the arm, and continue on throughout the tent repeating the same. Then, when you can hold no more, finally stop to evaluate what you actually have, returning the unwanted items to the shelves.Now.............. laughing to myself, recalling the conversation,............. as the line of ruffians begins to snake closer to enter the Aeromart tent at the opening bell.

Like Gardiner, I plan for 6 GPH. My stock wing tank is too small. I'd like another3-4 gallons, which I'll add, somehow, eventually. I'm really itching to get out after 90 minutes, and I'm relatively young and spry(& Don Emch is younger and spryer than I). If you live someplace with long legs between fuel stops I understand the desirefor lots of gas. If you don't, you may not need all that extra weight.

Hi Tom - I made a "hole" in the wing center section with fabric glued around anddown into the edge of the hole. The tank fits in the hole, is held down withstraps, and has an aluminum cover screwed on around the periphery, much likewhat's already been described.Notes: - If you go this route, the edges of the hole need to be really stout. I madea very robust wood structure on which to glue the fabric and still managed topull the structure apart when tightening the fabric. The fabric is astonishinglypowerful when it tightens up. I had to cut the fabric, re-do the wood structurearound the hole, and then repair the fabric. You don't really see it unlessyou look, but it was all a pain in the butt and very traumatic when thestructure broke loose. I think I said something like, "shoot!"- Not sure why you'd need to ground the aluminum cover.- I've had the tank out once for inspection and for repair of a pinhole leak. I was glad I made the tank easily removable.--------Kevin "Axel" PurteeNX899KPAustin/Georgetown, TXRead this topic online here:http://forums.matronics.com/viewtopic.p ... ______Date: Tue, 11 Oct 2011 11:24:17 -0500

Some of you may remember that back in October/November, Barnstormers had an adfor a Pietenpol project that was up in Warren, ME. 6 months of the year, I liveabout 35 miles from there so road trip it is. Bought the project on the spotfor several reasons. 1. The fellow and his son who built the thing also restoredand built classy wooden canoes; Old Town and the like. I saw the levelof craftsmanship on them and on the Piet was, embarrassingly, better than mineand not just a little. 2. The guy who did the welding of the landing gear,engine mount, and so on, is the head guy in the restoration shop at Owl's HeadTransportation Museum (ohtm.org). They fly rides in a Waco and Stearman andhave made FLYING replicas of a Bleriot, a Taube, a Curtiss D, and a bunch ofothers. He knows how to weld. 3. The father and son did not work in a vacuum.Some of you may know Karl Erickson. He's been around Piets for years andhas owned, I think, 3. He provided the equivalent of Tech Counselor advice.4. The project was essentially ready for cover, saving me probably 2 years.The plane had been assembled and the control rigging done so the major projectgroups left are covering, FWF, and instruments.This is all by way of preface. The duo covered the tail feathers and aileronswith ceconite and butyrate dope using 1.7 oz fabric and there is enough 1.7 ozfabric to do the rest of the plane. Meanwhile, I have purchased enough 2.7 ozfabric to do an entire airplane and gotten a start on purchasing the Stewartsystem glue and stuff.Finally, the question. What do I do with the tail feathers and 1.7 oz fabric?Looks like I have several choices. 1. Leave the tail feathers as is and dothe rest of the plane with either 1.7 or 2.7 fabric A local A&P says that youshouldn't mix em. 2. Strip the old dope and fabric off and start over witheither 1.7 or 2.7 oz fabric. 3. Just continue with the dope and use the Stewartanother day. All choices imply a question of which fabric is preferable.I am inclined to option 2 with the heavier fabric on at least the fuselage.Any inputs are appreciated. I've looked at the archives for fabric preferenceand found a spectrum of opinions. Does the use of the Stewart system change anyof them?Included in the pile o stuff was a set (4) of cub lift struts. For those of youwho have used them, would you do it again or just start with new? Again, thearchives are ambivalent.Thanks in advance.Dave AldrichRead this topic online here:http://forums.matronics.com/viewtopic.p ... ___Subject: Pietenpol-List: Re: Covering question

DaveIf I had bought an airframe ready to cover it would have saved me 11 (and stillcounting) years of building not two years.To name a few long time flyers Mike Cuy, Earl Myers and Steve Eldredge used 1.7oz. on their whole plane. I plan on using it too because I will eventually getto that point.>From the archivesGreg- Superflite was pretty good todeal with in sending me their 1.7 oz non-cert. fabric. They have a website too which is: http://www.superflite.com/cov.html#fabric They arelocated in IL.PS- the only thing I had to hunt around for was matching 1.7 oz. finishingtapes....the pinked edged stuff you put over ribs, leading edges, trailingedges etc. that comes in all kinds of various widths depending on yourneed. I had to order those hit and miss from whomever had them in the1.7 oz weight. Wicks, ACS, some independent Polyfiber dealers.If you use the 1.7 oz. try to use 1.7 oz tapes too. The reason for this isthat the 1.7 oz has a fine weave that will fill nicely. (read less coats, lesssanding, less weight, nicer finished appearance) If you use heavier gradesof fabric for your finishing tapes you'll find number one, they are more stiff anddon't lay down or curve around as easy as the lighter tapes, and number two,they have a more coarse weave to them and will take more schtuff to fill theweave to match the rest of your finish. It is fine to do though......just someobservations.Mike C.David; I always use the 1.7oz fabric with the textbook Stits or now the Polyfiberprocess. It gives a nice low luster finish plus I used the flat rib chordwith the knots pulled inside the fabric. That makes for a really nice finalfinish to the rib stitching, no knots.Mike Cuy had a standard dope finish with a brightener added in his finalcoat to give it a VERY high gloss...........I just wanted to stay with anantique finish which mostly were low luster even then except for thehigh-priced ships with hand rubbed Nitrate/Butyrate (dope) finishes.....Earl Myers I used the 1.7oz generic dacron from As&S. It was about$3.65 a yard. I used the generic tapes, and poly fiber products to glue itdown. rib stitching was with round cord, not flat.Steve E.--------ChrisSacramento, CAWestCoastPiet.comRead this topic online here:http://forums.matronics.com/viewtopic.p ... ______Date: Thu, 22 Dec 2011 16:28:24 -0800 (PST)

Just a guy who wants to fly here, I recently found this site and saw a pictureof an Pietenpol for my first time a few weeks ago and am in the very early stagesof fullfilling a life long dream... I have a 80 acre pasture behind my houseand for years have thought of flying something out of it. I learned to flyin 1973 when I was 17, took lessons and did a few cross countries in a Cessna,spent 12 years in the Navy, married, allowed life to get in the way and havenot flown in years. I wrote down the name Pietenpol on a piece of paper a week ago, went to an elderlyneighbor of mine who is a master mechinic, machinist, Model A nut and askedhim if he had ever heard of one. He gave me that look, said come in the shop,went to a desk started pulling old aviation clippings and articles, severalon Pietenpol's. Knew all about them. I am a former cabinet maker, do metal work and blacksmithing, have a shop fullof metal and woodworking machines, all my machines are old school manual machinesbut they seem to get the work done. Are there any members in the Arkansas, Missouri Oklahoma area who would like avisitor? I would appreciate getting to see a project or a completed aircraft. Also I am looking at the project presently on E-Bay, any thoughts or commentsappreciated. I know this would advance me a couple of years. The project is widerand some {4") has been added to the length. Can someone tell me if extralength would prevent me from going with the Model A Engine?Thanks in advanceRickRead this topic online here:http://forums.matronics.com/viewtopic.p ... ___Subject: Pietenpol-List: Re: Covering question
