    Subject: Re: Fuel tank caps for 601XL
    Looking at your pics my hunch was correct... you have the skins too close to the tank. I have the same caps you do and if you only use one row of cork on the bottom you will have close to a 10 to 12 mm gap between the tank and the top of the skin then you build around the filler neck with a couple of layers of cork to make up the difference and to level out the top of the neck. I will be building mine in a week and it takes me 2 weeks to finish them so I will post some pics on my web site.

    Subject: Filling Rivet Head Holes
    From: "rbjjr" <burkeandsusan@verizon.net>
    Searched for this first but found nothing so I'll apologize ahead of time if this has already been much discussed. Any thoughts on filling rivet holes and if so, with what? I (finally) have my rudder complete and seeing all those holes with exposed steel in them makes we want to fill them with something. Of course any filler would have to be non-corrosive, permanent and paint-able. Has anyone done this and if so with what kind of results?

    Hi Burke, Wait a bit before trying to fill those holes. You've got a lot of work ahead and the obsession with them is going to fade as you complete your aircraft. It's not a car and some things just don't require the type of detailing you see in the automotive world. I'd just prime and paint after putting the best spacing, set uniformity and straight lines into the rivets you do use. I never filled any of the holes and doubt you could tell from 10 feet away. http://www.macsmachine.com/images/completion/full/viewwingrivets.jpg Larry McFarland 601HDS at www.macsmachine.com rbjjr wrote: > > Searched for this first but found nothing so I'll apologize ahead of time if this has already been much discussed. > > Any thoughts on filling rivet holes and if so, with what?

    Subject: Filler
    All- I'm polishing 95%+ of my project, but don't see any way of making the top skin/tip fiberglass rib juncture look good without a bit of filler and paint. Not because of gaps, but "Crinkles".I've decided to paint just the nose skin and tips of the outboards and stab. I've seen projects that used regular Bondo and the damned stuff cracks and comes out. Fiberfil sticks great, but you can't work it like Bondo. I'm afraid of grinding off aluminum trying to smooth out the Fiberfil. Any alternatives, or should I just haul my outboards and stab to a paint shop and let them deal with it? Not that that's a guarantee- I remember a posting many moons ago where a paint shop ground off the tops of the rivets while painting. Bill Naumuk Townville, Pa. HDS Systems/Corvair 90%

    Subject: Filler
    Hi, I've been using a product from PACER glues, "FiberPoxi", code PT-45 for gluing and filling fiberglass, wood, etc for years very succesfully in scale air giant models that are sometimes more stressed than full scale airplanes , and has never been cracked . Epoxies are heavy, but this one is a bit lighter, flexible and very resistant, has an usefull worktime of about 15 min, and can also be painted after sanded with a 400 sheet. It=B4s also cheap and can be found in most airmodel stores. If you need more liquid epoxy for better penetration into little cracking, you can use the PT-40 , also light for an epoxy, commonly used for sheeting with fiber fabric, and has an usefull worktime of about half an hour. But it easily flows down if not contained (Newton's law, our common enemy). I've also used this products on sanded aluminium and isopor for gap filling and further painting and it will last in place if the surface are not exposed to a considerable bend.

    Subject: Re: Filler
    Hi Bill, I too am wondering how to deal with the small gaps left on my wing tips. One thing I am considering is to build up the fiberglass with epoxy laden flox. This is similar to filling with bondo or similar stuff, but instead of adding a new layer of material it actually bonds to the composite structure and becomes part of it. The flox will not be as easy to make beautiful, but that is not my goal. I am more interested in providing a good surface for the air flow. I am also planning to do a similar job on the front of my engine cowl. After installing both the top and bottom to my plane there are gaps in the front corners that I want to smooth over. Epoxy and flox should do the job with possible glass cloth in areas that need larger fills. It seems odd that the most difficult problems to fix on an "All Metal" plane are actually fiberglass issues.

    Hi Bill; I think the polished 601 will look great, but I'd put paint on anything called frontal edge surfaces. I used to clean a C-150 aluminum wings of bugs and the juice changed the character of the lead edges during cleaning. On my 601, the dark blue paint cleans up much easier than aluminum and the bugs are a little harder to notice right away. The bugs are very noticeable on a light color like my nose cowl, but oddly, they don't seem to collect on the rudder at all. http://www.macsmachine.com/images/completion/full/601ezfrontright.gif I'd keep the painting in-house if possible and use an acrylic-enamel if not a water-base urethane. It's not that hard once you get started with it. Do have a finished aircraft before beginning paint though.

    Subject: Re: Need to Order Fuel Tubing
    I used the 3003 3/8" OD aluminum tubing from ACS. This will work fine for the relatively low pressure of a typical fuel system. It is shipped coiled up, so it's easier to package and is soft enough to bend easily without tools. I don't remember ever seeing aluminum tubing at an auto parts store, most of the fuel tubing used in cars is made of steel. Copper could be used I guess, but it's heavy and pretty expensive right now and is not suitable for use with aluminum fittings.

    I think if I remember correctly it was 1 layer on the bottom is all and more at the top. In other words just as much as needed on the bottom to keep it from touching the skins. Also make sure your vent isn't holding the tank forward and off the spar. Like I said you can call if you like. Jeff **************Gas prices getting you down?

    Hello, list, I'm agonizing over my decision for a single axis autopilot/backup T&B in an all-electric panel. Does anyone have any experience, yay or nay, with either the Trutrak Pictoral Pilot or the Trio EZPilot. If so, please share it with me, either on this list or via direct email.

    Subject: Engine cooling question?
    Dear Bud, A couple of months ago we were talking and in our conversation you mentioned something about adding a piece of aluminum around the bottom edge of the lower cowling outlet in a Zenith CH601XLif I am not mistaken. With that in mind, do you have a picture of the installation? And does the addition of that "lip" change the cooling ability of the Jabiru 3300 FWF cowling and Kit? I mention this because I am still having some higher CHT temps on the #2 and #4 cylinders than I would like to improve my cooling of the engine. I would be very interested in what you have found. Thank you for your time and consideration in this matter.

    Paul- You're in close to the same situation as me.I don't have gaps, but the "Crinkles" left from trying to form the aluminum around the fiberglass. You're also basically talking about the same stuff as I'm thinking of using. It's Bondo with fiberglass threads mixed in. It'll never come off, but once it sets up it's like steel. I think I'm going to talk to a guy I went to high school with and owns a body shop. He's only 10 minutes away so hopefully I can get him to do the job without grinding my rivets off. Bill ----- Original Message ----- From: Paul Mulwitz To: zenith-list@matronics.com Sent: Sunday, June 29, 2008 12:49 PM Subject: Re: Zenith-List: Filler Hi Bill, I too am wondering how to deal with the small gaps left on my wing tips. One thing I am considering is to build up the fiberglass with epoxy laden flox. This is similar to filling with bondo or similar stuff, but instead of adding a new layer of material it actually bonds to the composite structure and becomes part of it. The flox will not be as easy to make beautiful, but that is not my goal. I am more interested in providing a good surface for the air flow. I am also planning to do a similar job on the front of my engine cowl. After installing both the top and bottom to my plane there are gaps in the front corners that I want to smooth over. Epoxy and flox should do the job with possible glass cloth in areas that need larger fills. It seems odd that the most difficult problems to fix on an "All Metal" plane are actually fiberglass issues.

    All- Think you'll get fewer "Blonde moments" as time goes on? Not in my case. You just can't teach an old dog to keep from pissing in the cockpit. I'm finish rigging the control cables prior to riveting the aft section of the fuse, so I cut two long ones for the rudders and two shorter ones for the elevator. I attach the elevator cables.

    Subject: Re: Filler
    Hi Bill, Actually, Bondo is a polyester resin based product. It will shrink with time. The stuff I would prefer is epoxy binder holding flox. I learned about flox and its use by purchasing a composite training kit from Aircraft Spruce. After starting on my FWF I learned there was a great deal of composite work needed in the kit from US Jabiru and the instructions seemed to assume the builder already is an expert at composite work. This would be true if we just finished building a Jabiru plane like they kind they sell, but I'm afraid my own composite knowledge was sorely lacking.
