    Subject: building in cramped workshops
    It is only recently that I've had the luxury of working in half of a "real" hangar. Up until then, I worked out of my half of a standard 2-car garage so I know what crowded means. I had racks overhead for long pieces of material and stuff stashed under the building table, on pegs on the wall, and everywhere I could find an available inch of space. However, there is something to be said for working in a compact shop- there is very little walking to do when going to get a tool, because everything is right there by definition. And the shop is easier to cool in the summer and heat in the winter. But the best part of all is that when you do finally roll up the garage door and you get to move the wing or fuselage out into the light of day, it is a real great feeling... almost like it is being born. I drive 18 min. each way from my house to the hangar and that is really terrific as some of you guys who have to drive an hour or more know. It's a deterrent to building or flying when you have to plan ahead for the thing just because the hangar or shop is so far away. When you build in your garage (or basement, or attic, or the shop in your back yard), it's a spur-of-the-moment thing. You can trot out to your project in flip-flops and shorts and get with it, with the result that you can scratch the itch on the spot. More gets done that way. Oh, and before I forget- that was a GREAT video, Jack! I found myself watching the control surfaces and cables as much as the scenery on the ground, to see how your airplane is rigged and how things work in flight. It was that way watching Mike Cuy's "smoking runs" video, too- I watch the cables and controls and the airplane's response as much as I do the fun flying stuff.

    Subject: Rib Truss design, ala 1940
    From: "Bill Church" <eng@canadianrogers.com>
    Tom, Those old publications are a lot more practical in approach than anything published today, that's for sure. In general, in all trusses (which the wing rib and the fuselage are), ideally the centerlines of the members would intersect (at points called "nodes"). This is the ideal way to construct a truss, with all members straight, and connections pinned, because then all members are either in tension or compression (no bending or shear or torsion). But we all live in the real world, rather than an ideal world. The top and bottom capstrips are not a series of short, straight sections, but rather, continuous, curved strips. And all of the joints are gusseted, not pinned, which will impart some bending forces when stressed. Because of the use of the gusseted joints, accurate alignment of the centerlines of the members is not so critical. One other thing to keep in mind when "designing" a wing rib for the Pietenpol is the fact that there are the drag/anti-drag cables criss-crossing through the structure, as well as the control cables, which must not intersect with the rib structures. One statement you made struck me as funny, though. You wrote that "this wing, using the original Piet airfoil, has flown 80+ years. The only change I've made is..." to change the AIRFOIL. Bill C.

    maybe ? Oh Man Jack! I just drooled all over my keyboard. Stinemetze McPherson, KS. Just had a nice weekend of flying - flew the RV-4 up to Smith Mountain Lake, Virginia, then did some Pietenpol flying up there. I took up a friend who has a nice video camera and he shot some good footage from the Pietenpol over the lake.

    From: "tkreiner" <tkreiner@gmail.com>
    This just in from David Paule, a retired Aerospace StrucStress analyst: I am not a member of the Piet forum, but I read it regularly. The reason why all the centerlines meet at the same place is to avoid local bending moments. I'll describe. If there were distances between the intersections of say an upright and the adjacent diagonal, then the cap strip would carry a bending moment equal to the vertical force from the upright times that distance. The bending moment would be transmitted through the gussets because there's no strength at the end grain. But the upright would carry the moment all by itself at the edge of the gusset, and the orientation of the bending moment would load up the upright in the flatwise direction, its weakest direction. This common intersection of elements, added to the triangular nature of the layout, is the difference between a "truss" and a "frame." Trusses carry only axial forces. Frame elements also carry bending. It's an important distinction, and since bars are better able to carry axial forces than bending moments, that's why light-weight structures are often designed as trusses. Incidentally, that book you referred to is a good one - I've got it. Thanks for mentioning it, that's a service to the community, especially the newer folks.

    Subject: Re: Rib Truss design, ala 1940
    Matt, You ARE missing something-- about four or more years of intermittent discussion of alternative airfoils, whether NACA 2412, Clark Y or USA 35B, or most notably Riblett airfoils, and among the last the Riblett 612 in particular. The 612 has a more bulbuous nose (bigger radius) and is thicker (taller, more Y-axis) at its thickest part, than the Piet rib. The "12" in "612" means that the highest Y is about 12 percent of the length of the chord, whereas the Piet airfoil is about 8 percent, sometimes stated as "7 percent," but it seems higher to me (from memory, not looking at either a rib or a drawing, sorry). People using the NACA 2412 or Riblett 612 claim higher cruising speeds, similar climb rates, and softer stalls on landing flare than if using the Pietenpol original-- BP's FC 10. Several builders are now building the Riblett ribs and will use that wing. Lowell Frank is likely the only builder and flier who has changed wings on the same plane, and flown them both, so as to have comparative data. Several people have run comparative airfoils through X.foil and the like, and if you are interested in that, take a look at airfoil.com, checking the archives and attached files there. I don't think anyone has ever run a wing based on a Riblett or a Piet FC 10 through a wind tunnel. If so, please correct me. Riblett himself speaks poorly of the Pietenpol airfoil, but then he doesn't speak well of NACA, either. A few builders have spoken with him, and he recommends the 2412 among NACA airfoils, but especially either his 612 or 613.5 airfoils for a Pietenpol. Check the matronics Piet archives for more info and discussion. Include in your reading pitching moments, center of lift, and the like, which has all been well discussed on this site. BTW, there is a strong opposing view. Many experienced builders and Piet fliers say that the original FC 10 is as good or better than so called improvements and has the further advantage of being authentic Piet and very, very time tested. A few builders seeking more lift have pointed out that the builder wanting to operate in thinner air or carry heavier loads could add four feet to the wingspan and be assured of more lift. That is as XXXXXXXXXX "fair and balanced" as I can be. For me it felt slightly like a migraine headache ;-) Judge for yourself, but please first read the many, many posts. I have "given at the office" on this one myself, and have little interest in opining further until I have flown the same plane with different wing sets, which I may do, but first things first.

    Okay sports fans. I will being arriving Ontario Ca Tuesday evening the 15th then on to Nipomo, CA 16,17,18. I have no idea where that is nor does it matter except for the obvious question. Any Piet projects in the Nipomo Ca area to look at or check out? From what I know at the moment its about 40 minutes out from Santa Maria. that's the extent of my knowledge on that topic Not sure about timing, but thought I would ask. and I may have access to wheels not too certain about that or when. contact off list please John Do not archive

    Matt=2C If Pieti Lowells performance is to be believed=2C and I think it is since I have seen videos of him taking off. Then you would gain more lift (Read b etter climb) and a lower stall speed since the 613.5 and the 612 stall at a higher angle of attack. I wonder though if most of the performance doesn 't come from his highly modified Model A (close to 90hp). Me=2C I'm going with the std airfoil. I will seek Lowel's advice on the Mo del A though. I can always build a different wing for not a lot of $ down the road. I agree with mike cuy. Just put a longer wing on it.

    Okay. I didn't mean to awake a beast, but it just seems to me that for most guys' missions sticking to the plans is reasonable. I mean, really, is an extra thirty seconds to get to a thousand feet really going to matter on the average Sunday morning? I can certainly understand making safety-related changes like significantly reducing landing speed or taming bad stall characteristics (to the extent they even exist in the Piet). I'm also building an RV and no reasonable effort or expense will be spared in making that as fast and light as possible, but trying to eke climb or cruise performance out of Pietenpol seems a bit ridiculous to me unless you have a specific need.

    Matt=2C I think for those of us who are of std FAA weight and operate out of 3=2C00 0ft+ strips near sea level the std configuration is fine.

As I said before I question the merits of pu tting one of the Riblett airfoils on as opposed to adding 4ft to the wing s pan. Tough to beat hp and wing area. But on the other hand.

    Makes sense. I'm 170# at 630 MSL. The real reason I brought it up is that Tom (started this thread) is also designing MY wing. So whatever he does is what I'm gettin' (unless I strike off on my own). Just want to make the right choices in the beginning and I'm always skeptical of anything that resembles a rabbithole.

    Subject: Fuselage building for Continental engine
    I have a few questions for building the short fuselage to use a Continental engine. - Are the large plywood "sides" needed on the inside up front by the top-en gine mount brackets if the "model A shelf" will not be built? Can I use nor mal size gussets for-those top-engine mount brackets and some wedges? - The plans for the model A show the large ash cross member up front connecti ng the sides at about 4.5" down from the top. Is this heavy ash member stil l needed for a Continental and if so, can it be moved up closer to the top, nearer the top engine mount brackets?- Or can a spruce piece be used up at the top same as what is shown for the bottom?- (The bottom piece is 3/ 4" X 3/4" spruce...seems a little small.) - Lastly, for now,- most of the various braces are 1/2" X 1". Do I stand th ese pieces up so they are 1" tall like the longerons, or lay them flat- s o they are 1/2" tall? - Thanks is advance.

    Subject: powerplants for the Pietenpol
    My Pietenpol has the 85 Continental with 72/44 prop wood. I have owned many certified aircraft, but the Piet is the most fun of them all! Takes off i n less than 400 feet at 40 indicated and climbs at 500 ft per min at 50 ind icated. I like to throttle back to 2000 rpm and it holds altitude while cru ising at 60-65 indicated. How much fun is that! While it is not the roomy a irplane that has an enclosed cockpit that some may want, this is the plane that brings one back to the basics of flying, enjoying the scenery, waving at friends, and not paying those huge airport fee's for parking, repairs, a nnuals, etc. etc. It fit's my pocket book perfectly!

    Alright now if you are anal about wedges and gussets then you must go to the Flitzer web page and look at the fuselage all those wedges and gusset's blowed my tiny Bozo brain. Check the Connecticut Flitzer Werkes out I'll have to wow the pictures, In my opinion we all know the Germans usually do it right(well untill the Russians come up with the T-34) so here you go an updated modernized version of wedges gone wild.

    Subject: Re: Rib Truss design, ala 1940
    From: "Bill Church" <eng@canadianrogers.com>
    Okay Tom, As long as you're going to maintain the truss locations per the original Pietenpol rib design (which don't actually have dimensions on the plans - but that's another issue), you won't likely run into serious difficulties with the cables. Worst case, you might need to shift a rib location an inch or two to the left or right. It was because you wrote: "Since I've designed - along with Harry Riblett himself - a Piet rib using the GA30-613.5 airfoil..." that I assumed you had come up with your own arrangement of the truss members, and might have some interference issues ahead of you. Bill C.

    While I don't argue the ability of the Germans to 'do it right', the Flitzer is designed by Lynn Williams, who resides in the UK.

    Yes that is true but I think the original was a German polar exploration plane built right after WW-1 and Lynn added his extraordinary imaginative design skills to the original to build this absolute beautiful and aerobatic bi that's flys on VW power. I have speculated about the fuselage built enclosing the shoulders with your head sticking out was this to help you stay warm on a polar exploration. Of couse German is good but my old Ford will out last your Mercedes. Correct if this isn't correct.

    Hehe....been chatting with the Baron Morrisov, perhaps? The Flitzer is completely the creation of Mr. Williams. It is not based on any WW1 airplane...it's just supposed to look the part, and be a simple, fun airplane for those with a Walter Mitty bent. :P Ryan On Tue, Sep 8, 2009 at 9:39 PM, Robert Ray <rray032003@gmail.com> wrote: > > Yes that is true but I think the original was a German > polar exploration plane built right after WW-1 and Lynn > added his extraordinary imaginative design skills to > the original to build this absolute beautiful and aerobatic > bi that's flys on VW power.

I don't usually reply to my own messages, but I'd like to apologize to the Grega fans for the sound of the above. I referred only to the degree of reinforcement, not to the flying or aesthetic qualities of the Grega modification. Nonetheless, the comment sounded pretty snide. It wasn't intended. Owen

    I am putting the naca 23012 on the piet, as suggested by Hobert Jones who built and designed several planes, he didn't have anything negative to say about the airfoil he just had an affinity for the 23012 on the Taylor Craft.
