    Subject: Center Section Cover
    This week, someone sent an E-mail on the list about his cover for his center-section storage compartment. I also am in the process of building my center-section and want to build a similar cover. I mistakenly deleted the E-mail rather than saving it. Will the kind person re-send the E-mail with the pictures of his cover -- you might send a couple more pictures if you can. I need all the help I can get. Thanks a bunch, Chuck

    Very nicely fabricated Kyle. It appears as though your workmanship is real ly top notch. I'm very impressed at how the standard of Pietenpol craftsmansh ip has continually gotten better over the past ten years or so. Outstanding w ork going on out there in little shops, garages, and basements around this land and far off lands. Beauuutiful work. Mike C.

    Michael, thanks for the reply. I was going to ask Kyle but I'll ask you instead, what thickness aluminum sheet did you use? I was thinkiing of ordering enough to do both the cover and the cowling around my Corvair engine as well as the cowls on the fuselage. I have Hans Van DerVoort's drawings for his engine cowl, but he doesn't stipulate the thickness of the material. Chuck ----- Original Message ----- From: Cuy, Michael D.

    Michael, Chuck again. I just went to your pictures on the west coast web site and saved a bunch of your pictures for future reference. You might just expect a bunch of questions later on.

The other 1/2 of my hinge is riveted to the aluminum cover.

    Chuck, I used 2024 T3 .032 throughout my lid. It worked nicely for me. Kyle -------- Airspeed, altitude or brains: Two are always needed to successfully complete the flight. Read this topic online here: http://forums.matronics.com/viewtopic.php?p=368062#368062

    I'm going to be down here in Lakeland for a work contract, but will be at the show. Is there anyone coming down here, that I may be able to get together with. I would like to take some pictures, ask questions, and maybe get a ride. Thanks guys! J_Dunavin@hotmail.com Read this topic online here: http://forums.matronics.com/viewtopic.php?p=368067#368067

    Chuck, Hans' drawing actually does specify the thickness (.025), just above the Bill of Materials chart. http://mykitplane.com/Planes/PeoplesFiles/Cowling%20drawing.pdf Bill C. Read this topic online here: http://forums.matronics.com/viewtopic.php?p=368076#368076

    Chuck, Here is a picture of my trial fit. Still need to figure out a way to mount the piano hinge to my front spar in order for my piano hinge to mount flush with the "skin" I may need to bond a strip of wood to the top of my spar to take up the gap and then mount to that. My method of attaching will still be truss screws. Kyle -------- Airspeed, altitude or brains: Two are always needed to successfully complete the flight.

    Jim: Think about this from a theory point of view. When the points CLOSE, the C is out of the picture -- it's shorted out -- so you have an RL circuit. As the field builds up, the current goes from 0 toward a steady state that is determined solely by the R in the circuit. That R is a function of the ballast resistor and the internal resistance of the coil. The RL time constant determines the shape of the first part of the curve I drew. Side note: Notice that the faster the engine runs, the earlier on that curve the points open. That means less energy stored in the coil to produce a spark. As a conventional system speeds up, the spark actually becomes weaker. Not so with magnetos. The faster the magneto turns (up to a point) the more energy is available. The faster a wire moves through a magnetic field, the more induced voltage. The slower the movement, the less voltage. That's why magnetos can sometimes be hard to start and why impulse couplings were developed. The impulse coupling accelerates the magnets through the windings in a ratchet kind of motion. Now the points open. You have a series RLC circuit with a DC supply voltage. That is a circuit that cannot resonate and is what is called a band pass filter. Only frequencies in a range around the square root of 2*Pi*L*C if memory serves, will get through. DC will not. The graph I drew is actually incorrect. The current in the low voltage/primary winding actually drops to zero almost immediately. The energy stored in the magnetic field of both coil windings has only one way to dissipate and that's through the high voltage/secondary side via the spark plug which has much less effective resistance than the primary side. What you may have read about is some of the solid state systems may have a resonant circuit used to charge a capacitor in a system commonly known as a CDI for Capacitor Discharge Ignition. There is no such thing as a DC transformer so in order to get a higher than 14 v supply, the system either uses a resonant circuit or chops dc in very short on/off pulses. These look like AC to a transformer and by proper selection of windings, you can get almost any AC voltage you want. Rectify it and - voila - high(er) voltage DC. That's the principle the 110 v adapters you plug in your cigarette lighter work on. This is probably one of those cases of "ask me what time it is and I'll tell you how to build a watch". Hope this helps. Dave Read this topic online here: http://forums.matronics.com/viewtopic.php?p=368085#368085

    Subject: Re: center section storage lid hinge-to-front spar
    Yeah, Kyle, that's what I did to make everything line up. I just cut a piece approximately the shape I needed, glued it on, and then shaped it with a block plane so that everything lines up. Your pic looks great. I was originally planning to cover just the area between the main spars. I'm about to run it on back to where the aileron spar goes -- like Mike and, apparently, you did. I also liked Mike's design of the little compartment where he can get to the aileron cables and pulleys. Thanks for your help.
