    Subject: Building place..es
    Mario great idea. My shop is a lower level family room and garage when needed. My wife said if I was going to build a plane it had to be at home. The 16 by 4 foot table has been a blessing. It will be removed when the Piet is on the gear. I have all the tools needed, sanders, drill presses, band saws, mill sand blaster, routers, in the lower level. My table saw, lathe and welders are in the garage. It's roomy but packed with airplane parts, tools, vacuums and tool boxes. I usually move something to have room to fart. Not many pictures of just the shop but attached are a couple. I have my name in for a hangar at the Des Moines airport because the smaller field north of Des Moines I planned to use was closed.

I think the building place is something very important to take in account before begin, and see some examples bigs and smalls can give more determination to begin.. or not. I saw very clean and big places, and others very smalls; it come to my mind the one piece wing of Chuck Gantzer crossing two or three rooms, i don see it very clear in the photos. An extrem example is this one http://goo.gl/9qNbT I am going to post some photos of mine, I start in a room over my parents house garage, this place was unused, so I went there. There I build the fuselage and the empanagge, when the fuselagge was quasi ready, we download it to the garage below the room and I begin the first wing.. when the second wing was assambled I lost this room for xx reason, so, I download one wing to the garage and hang it over the fuse, and get the other wing to my home, and hang it to the roof to make place for the car. and this is my actual situation, the fuse and one wing in my parents garage and the other wing at home. It's not very comfortable work at home, the space is very reduced, and permanently are bikes, surfboards, grass cutter, etc going out and in.. but it's what I have, and when I am angry about that, I saw the Taylor titch video.. anyway, just to kill time with a cofee in hand.

    Subject: Corvair cowl
    I just finished up my nose bowl and I am getting ready to do the engine cowl for my Corvair powered Piet. I am basically following the plans posted by Hans van der Voort, but I am unsure of a couple of points. First of all is it OK to just use wood screws to mount the mounting tabs on the firewall? Secondly, I understand how the panels and nosebowl all fit together, but what is the purpose of the side strips on the plans (see attachment)? I am using the standard William Wynne motor mount. Are these side strips used to attach the cowl to the motor mount or are they just stiffeners? Are there any attachments of the side panels other than to the top cowl, firewall and nose bowl? If anyone has picture of their installation it would sure help me out. Rick Schreiber Valparaiso, IN

    Subject: cowl attach tabs
    Rick, I used stainless truss head wood screws to screw my cowling attach tabs to the firewall. They screwed thru the thin 1/8" firewall and then into the fuselage framework on the sides and bottom. On the top I glued 'backing' plywood squares to the backside of the firewall so the screws would have more depth to bite into on those uppe r tabs. Worked like a charm. According to the Tony Bingelis books, cowlings should never be attached to the motor in any way because of engine vibration and shake, especially during start up and shutdown. Canteliever the whole thing off of the firewall and you will get long life out of your cowling. I know some might be getting tired of me mentioning my Uncle Tony but he has some outstanding advice on cowling design and attachments and he saved me a TON of weight up there. I'm often time surprised at how battleship-like some cowling attachment methods are when they don't have to be. Mike C.

    Hey all, Completely and totally off-topic, but. For anyone interested, Marci and I are going to host a ten-year-old Ukrainian Orphan this summer to give him a break from the grim existence of an eastern European orphanage. Our aim is to just love on him, let him experience a (fairly) normal family life, get some English going ( a BIG help over there) and to give him some unique experiences. We PLAN on bringing him to Brodhead to camp with us. Hopefully I'll be flying and Marci will be driving, so he'll ride with her and will hopefully have a great time. We pay the expenses to bring him over, and if anyone is into helping out with this sort of thing, the link is below. http://www.active.com/donate/summer2013/Viktor God Bless! Douwe

    Well this is totally off-topic so forgive the intrusion good people but am I the only one who would rather hear the sound of this gorgeous Rolls-Royce Merlin engine than heari ng Marvin Gaye singing "Let's Get it On" ? Listen to how incredible this engine sounds (not to mention the beautiful s moke system) until the guy ruins it at the 25 second mark.

    Hi Steve, The horizontal stabilizer on my Piet has a gap at the front also and I was =C2-planning on adding a shim of plywood there to help make the front of the stabilizer less able to be vibrating up and down at that point. Jim B.

    Hans can correct me if I'm wrong. He's the engineer. Yes, I believe the side strips are for stiffening. I didn't install the strips initially and ended up adding them later when I started getting little annoying cracks. I used Hans' method for attaching the cowl, similar to what Mike Cuy posted: little aluminum tabs cut out of 90 degree angle. Attached them through the firewall into the fuselage structure with wood screws. Attached the cowl to the tabs using clip nuts. I routinely checked the security of the wood screws and they would get loose occasionally. I'd put a dab of JB Weld in the hole to help secure them. -------- Kevin &quot;Axel&quot; Purtee Rebuilding NX899KP Austin/San Marcos, TX Read this topic online here: http://forums.matronics.com/viewtopic.php?p=395829#395829

    I am in total agreement Mike. Nothing beats the "music" of a Merlin engine at full song. I also was mesmerized watching those smoke trails and seeing how they both got caught in the wingtip vortices behind the airplane. I noted that the smoke generators sat about one third of the span of the wing, right under the first gun port on each wing so the vortices must have been drawing closer to the airplane centerline the further back they were. Made for a real pretty effect but also a good visual on those invisible tornadoes left behind by the big fastmovers. As my flight instructor told me when we were out in a Cessna 150: " Everything is bigger than us so be aware of those things." Thanks for sharing.

    Mine also has a natural gap there that needs to be filled with plywood. The gap is formed because the "spar" in the horizontal stab is thicker than th e leading edge. It is REQUIRED.

    Subject: Steve Dortch's actual question was......
    <steven.d.dortch@us.army.mil<mailto:steven.d.dortch@us.army.mil>> The bird I bought had a "shim" of plywood inserted under the front of the h orizontal stabilizer. I have discussed this with John K and we are both inc lined to leave it out and see what the initial test runs inidcate. Steve-- My guess is that since the front end of your stabilizer was shimmed up a bit that it was to correct a tail-heavy hands-off flight situation by deflecting the air slightly down and thus raising the tail. I would compare your we ight with the weight of the gentleman who flew the plane last and if compar able I would leave the shim under the front of the stabilizer. If you leave the shim out you may have to hold forward stick in level flight. Mike C.

I think Dan and I were both responding due to differences in thickness of s tab spar versus leading edge that you needed to shim up the leading edge. Thanks for the additional information; Shouldn't leap at first conclusions. Thanks, Jim B.

He's the engineer. Yes, I believe the side strips are for stiffening. I didn't install the strips initially and ended up adding them later when I started getting little annoying cracks. I used Hans' method for attaching the cowl, similar to what Mike Cuy posted: little aluminum tabs cut out of 90 degree angle. Attached them through the firewall into the fuselage structure with wood screws. Attached the cowl to the tabs using clip nuts. I routinely checked the security of the wood screws and they would get loose occasionally. I'd put a dab of JB Weld in the hole to help secure them. -------- Kevin &quot;Axel&quot; Purtee Rebuilding NX899KP Austin/San Marcos, TX Read this topic online here: http://forums.matronics.com/viewtopic.php?p=395829#395829 nbsp; -Matt Dralle,=========== href="http://www.matronics.com/Navigator?Pietenpol-List">http://www.mat ronics.com/Navigator?Pietenpol-List href="http://forums.matronics.com">http://forums.matronics.com href="http://www.matronics.com/contribution">http://www.matronics.com/c om/Navigator?Pietenpol-List" rel="nofollow" target="_blank">http://www.href="http://forums.matronics.com/" rel="nofollow" target="_blank">htn" rel="nofollow" target="_blank">http://www.matronics.com/contribution====== ======

    Subject: Sky Scout fuselage
    I have a young friend who is building a Ford powered Sky Scout along with his father. I was asked a question by them the other night that I can't answer. The plans in the 1933 Flying and Glider annual list one fuselage length and the plans from the Pietenpol family lists another. They were wondering what the correct length is. I know the reasons for the different fuselage lengths on the Air Camper but I don't know what everyone is using on the Sky Scout. Is the longer fuselage for the lighter Continental powered ships? I think the shorter fuselage was for the Ford powered ship, but I could be wrong. Rick Schreiber Valparaiso, IN
