Hello,I know this topic was discussed before; but I just want discuss an idea about it.I agree that cut a longeron is a bad solution/idea/etc, the fuselage look so cleanwith them.. but the big problem when cut one is the lost of compression andtension fuselage the longerons hold .The solutions I saw for this in the web was reinforce the side panels a lot whitothers wood pieces, etc; but I ask, it is possible to restore the longeron integritywith a kind of join that we can put and take out easily? I thought inthis draw I did, one side of the central piece (it could be square iron tube)attached to one end, and the other we can fixed with a couple of bolts. It willgive us a little work open and close it, but I think the stiffnes of all thepiece could be restored with something like this.... ;o)what do you think? any comments?regards--------Mario Giacummohttp://vgmk1.blogspot.comRead this topic online here:http://forums.matronics.com/viewtopic.p ... ttachments: http://forums.matronics.com//files/long ... ______Date: Wed, 17 Aug 2011 13:22:47 -0400

You need to calculate the transitional loads through the frame structure, one sectionwill effect the rest. If you do not do the math, I would not do it.

Mario,There are no dimensions given in your sketch, so it's really impossible to givea definitive, true answer, but in general, I'd say that this is not a feasibledesign.First off, it looks as though there are a number of bolts located very close tothe ends of the wood pieces. That is not a good design practice, as the boltswill just pull through the wood.Secondly, very short fittings as you have drawn, would result in concentrated stresseson the wood at the fittings.And thirdly, the practicality of such an arrangement, where a door must be securedwith bolts that need to be removed to get in to the seat, then reinstalled,and tightened properly before flight, then repeated again after flight, ismuch too cumbersome to be considered an advantage. The likelihood of the boltsnot being secured properly EVERY time is extremely high.Bill C.Read this topic online here:http://forums.matronics.com/viewtopic.p ... ______Date: Wed, 17 Aug 2011 15:02:03 -0500

Dan,I'm using a static port. Don't know if it's any real benefit from justleaving the ports open on the back of the instruments. Maybe I should tryopening them up - I might get more airspeed and get to Brodhead in 10 hoursinstead of 12 :-)Jack PhillipsNX899JPSmith Mountain Lake, Virginia-----Original Message-----

Bill,I agree with you, open and closing with bolts it's an uncomfortable idea, but Ithink (I did't see any statistic about) that the major time the piets fly withjust the pilot.. about dimenssions, of course, it just an idea, not a design.I do not messure anything yet, i am going to do it.. so from yours three pointsI am going to see 2, the lenght of the fitting, and how to fix the square tubeto the wood without damage to much de longeron.--------Mario Giacummohttp://vgmk1.blogspot.comRead this topic online here:http://forums.matronics.com/viewtopic.p ... ___Subject: Pietenpol-List: Re: Idea about front cockpit side door

Post by matronics »

Original Posted By: "Bill Church"
Mario,I think you'll find that the fittings would need to be so long that there wouldnot be a large enough opening to make access to the front seat any easier.Really, the best way to incorporate a front door in an Air Camper is by buildinga steel tube fuselage. The welded steel joints are much more able to properlytransfer the structural loads. Putting a passenger door in a wooden fuselagerequires a significant amount of extra wood (extra wood = extra weight, and extraweight means that your passenger carrying capacity is lessened).I have spoken with a Pietenpol builder who eventually also became the owner ofan Air Camper with a door, and found the Piet with the passenger door to be noeasier to get into than the standard Piet (no door). It has something to do withthe position that one must be in to enter the front cockpit, and having thedoor did nothing to make it easier. That's what he told me.In any case - be careful with any modifications.Bill C.Read this topic online here:http://forums.matronics.com/viewtopic.p ... ___Subject: Pietenpol-List: Re: Two Part Post- need help in SE Ohio looking at a fuselage

I'd say that $1000 for a well built steel tube fuselage, built with 4130, completewith landing gear and control stick assembly is a deal. Subtract the costof materials and divide the remainder by the number of hours of work, and youhave one very poorly paid welder.On another note... Just curious, but how is this a "Two Part Post", as referredto in the topic title? Where's Part two?Bill C.Read this topic online here:http://forums.matronics.com/viewtopic.p ... __________

Dan asked->is anyone else using an external static port, or is >everyone just leaving the static ports open on the back of>their instruments?On 41CC, Corky installed a full pitot-static system as well asa venturi for the gyro instruments. The pitot tube is on thestarboard side, mounted to the jury strut, down a ways from thewing so as to be out of the effects of the wing.The static ports are on each side of the fuselage aft of the pilot's seat, pretty much where the elevator walking beam stationis located... if memory serves. Plastic tubing connects everythingto the instruments.I think the ASI on 41CC is quite responsive and accurate, but Ihave not experimented with it with the fuselage static portsdisconnected and just sensing "cabin" static pressure. I have never noticed any area of reverse sensing or ram effect, even ina sideslip.Oscar ZunigaAir Camper NX41CC "Scout"Flying Squirrel N2069Z "Rocket"Medford, ORwebsite at http://www.flysquirrel.net ________________________________________________________________________________Subject: Re: Pietenpol-List: external static port

My ASI is so wildly erratic that I don't even look at it. Tried different static port locations to no avail. Admittedly I haven't checked to see if the ASI is OK yet. I bought it on Ebay. Maybe if I just hook up a vinyl pitot tube to the back and hold it into the windstream to see if it registers better? When I was at Brodhead Billy Mcaskil (sp) suggested I put a straw on the pitot to get it more ahead of the wing LE to see if that helped....it didn't. Oh well, who needs airspeed in a Piet anyway?

Charles,I once asked her if it was possible to incorporate it into a fuse with the sides already on & she said yes, but with some difficulty and the finished product might not be as good as if starting from scratch. I'd think it would be a lot easier if you don't have the plywood on yet. Hopefully, you haven't varnished anything yet either.She posts to the list on a regular basis, so her contact info is in the archive.Kip GardnerOn Aug 19, 2011, at 9:22 AM, Charles Campbell wrote:> Could Keri Ann's design be incorporated in a fuselage that is > basically complete except for the side plywood and turtle deck?

Subject: Re: Pietenpol-List: Re: Idea about front cockpit side doorMario,At one point I was all set to install the front pit door, had it roughed in and supported with a design that made sense and transferred the loads both down and around the proposed opening, not doing the math or analysis planned as a next step. Before fully committing to the door I stopped and I decided against it, for the following reasons:There are 4 longerons that pretty much support the length of the airframe, cutting one and reducing that strength by 25% made no sense, and to tell you the truth frightened me to a point that I would have no piece of mind wondering if the other longerons were able to support the load and flexing moments placed on them. Just too scary for me to want to fly withMaking that major structural change for an occasional passenger that may be too large to fit or may weigh too much to fit didn't make sense either. plenty of smaller people that want to ride and require no doors or reasonable accommodations, ADA compliantThe occasional large passenger vs a permanent structural change that may weaken the airframe, I plan to fly it all the time and take passengers on occasion, why make that sacrifice of strong airframe integrity for the occasional passenger. Makes no sense here eitherThere are plenty small, light weight and flexible folks that can and do fit easily into the front pit, why change the airframe to accommodate the unfitting few? repeat of the pointI just can seem to justify cutting a major structural component, compromising the integrity of the airframe to accommodate the once or twice rider.makes no sense here eitherI am a full size person, a builder and a damn good pilot, I don't ask for nor do I expect to be offered a ride, my size and weight preclude that. I understand it, I accept it and I make no excuses for it. That's the way it is and I make no bones about it. Weight and balance, flying over gross are just two of the important aspects of consideration in aviation. Why mess with something that needs not be compromised ?I am certain any rider you plan to take in your Piet will greatly appreciate the ride over the fence on take off rather that going through it onan attempted takeoff. Compromises in safety are not compromises at all but the commitment of poor judgments and dumb acts made by foolish people. And the opinion of the writer bearing no value to anyone determined to kill themselves or others though poor decision making.JohnSafe in the morningIn a message dated 8/19/2011 10:40:53 A.M.

1. What is your favorite color? (A little touchy-feely, I know, but you certainlywould not want to paint it your LEAST favorite color.)2. Is there an airplane that you have seen before that you would like to make thePiet look similar to? There are tons of examples of Piets in Warbird colors,Piets painted like Golden Age airplanes that have been seen in museums, etc.3. What do you think looks like you? Another touchy-feely question, but your car,motorcycle, boat, AND airplane are a reflection of you. Otherwise we wouldall drive black or white cars.Just a couple of thoughts. I already have my paint scheme designed, and I am juststartin on the wing ribs.

Tom,As is often the case, it's Tony Bingelis to the rescue (see attached article).I've gotta say that having access to the entire library of back issues of SportAviation, with "search" functions is practically worth the annual EAA membershipfees. That only took about three minutes to find.Bill C.Read this topic online here:http://forums.matronics.com/viewtopic.p ... ttachments: http://forums.matronics.com//files/1989 ... ___Subject: Pietenpol-List: Re: Fuselage pass through sealing

I have a drawing that I wanted to present to the group, but my scanner/printer is not working properly. So I will have to try to describe the step in words rather than the picture. I'll try not to use 1000 words. :>)Under each seat sticking out of the fuselage is a retractable (telescoping) step. Each step consists of the following. The lelft side of the step is fastened to the lower. left longeron. Five inches into the fuselage is a 1X 1 X 5 block, parallel with the longeron, which supports the inner end of the step. The outside of the step consists of a piece of 3/4 dia tubing, .035 wall thickness, 6-1/8 inch long. The tubing is held to the longeron and 5-inch block with metal straps. Inside the outer tubing is a piece of 5/8 dia .035 wall tubing 11-3/8 inches long (plus a little to run an AN3 bolt with nut which acts as a stop.) On the left end of the smaller tube is welded a round plate 1-3/4 inch dia. (which acts as a stop to keep your foot from sliding off in the extended mode and a asstop at the fabric line in the retracted mode.) Thus in the extended mode you would have about a 5-1/2 inch step; in the retracted mode the round disk would be flat against the fabric of the fuselage. Hope that is clear -- I can't send a picture.

Thanks Gary... if you or Clif wouldn't mind, could you forward that informationto me so I can read his notes too? I've already e-mailed Clif directly witha few more details on our proposed construction... perhaps he will see this andshare those thoughts. gboothe5(at)comcast.net wrote:> Mark,> > As you know, I'm not flying yet, but mine are laminated hickory.

Chuck,I like your idea, however, I am neither a graphic arts specialist nor an engineeras well. But I was thinking 2 additions-1. Could you put a short L-shaped notch on the inside end of the larger diameterpipe, so you could pull the inner pipe with the AN Bolt screwed into it intothe notch and turn it slightly to lock the step in place as it is in the extendedposition. 2. Could you somehow attach a small spring to the end of the pipe to give it alittle tension in order to keep it retracted in flight. That way it would notpossibly keep vibrating out into the open position. There is enough drag alreadywithout adding a pipe sticking out, even if it is small.Just my $.02, but I definitely like your idea.--------Semper Fi,Terry HandRead this topic online here:http://forums.matronics.com/viewtopic.p ... ___Subject: Re: Pietenpol-List: Re: Idea about front cockpit side door

Terry, it was not my idea! I got a bunch of prints of different things somewhere and this print was among them. I suspect that it was originally part of the GN-1 plans. I'm not sure of that but someone drew up the idea. Jack Trexor suggested that I take a picture of the print which I will try. If it works out I will post it. Your suggestions sound great to me.----- Original Message -----

Is somebody/someone (how you say that? one/body.. I always forgot it) realy interestedin this "other" solution?. I was looking just for the Piet plans andin particular the point the engine supports are fixed. In this 4 point there isa lot of forces playing when the airlen take down, and there are simple boltsjoins; the iron pieces could be bigger or smaller.. I do not know, but thereare lot's of holes where the longerons end.. and it work fine!!!!!I think the moment that this point play there major work is when the airplane touchdown... the engine want to go dow still, so there is a great traction forceapplied to the upper joins.. I am ok?... now thinking in the longeron suggestesdoor, i think the forces are slower than that's of the engine mount point.Am I wrong?.. I am just playing with dynamic and statcis forces...Let's burn some more neurons... ;0)good night--------Mario Giacummohttp://vgmk1.blogspot.comRead this topic online here:http://forums.matronics.com/viewtopic.p ... __________

Could Keri Ann's design be incorporated in a fuselage that is basically complete except for the side plywood and turtle deck? How can I get a set of her plans? C----- Original Message -----
