I spoke with Sheldon Dean of Dean Corrosion Technology. He is also the editor of the Journal of ASTM International. Heres what the Journal says about him: Leading the Editorial process of the Journal is Sheldon W. Dean, Jr., Sc.D., President of Dean Corrosion Technology, Inc. and formerly of Air Products and Chemicals, Inc. Dr. Dean has gained worldwide recognition for his outstanding contributions in corrosion testing, standardization and leadership in the voluntary standards system within both ASTM and the International Organization for Standardization (ISO). Dr. Dean has been an ASTM member since 1965. He has authored more than 95 publications, is primary author of six standards, and has assisted with 20 others. He has also edited seven books. A large number of these standards and publications are used throughout the world in materials and corrosion technology. This is a water stain, a type of corrosion. It starts out blackish then over time it turns white. This is aluminum hydroxide, which forms instead of the oxide. A protective layer of aluminum oxide is formed from the oxygen in the air. The hydroxide is formed when it is exposed to water. Once the corrosion is removed, a feint stain pattern might remain or recur at a later time. This could be easily removed by polishing. The surface could be primed and painted, in which case there would be no further evidence of the corrosion. There are no damaging physical or chemical changes made by a superficial layer of this corrosion. If the stained sheets are dry now and remain so, there will be no further corrosion even when stored this way for a few years. Acid etching also does not promote corrosion. The protective oxide layer will form. Aluminum may be acid etched and stored dry without a conversion coating. There is no benefit to applying a conversion coating when the sheets will remain dry afterwards. Removing the stain/corrosion could be done with an acid etch and scotchbrite, or possibly with scotchbrite alone. The latter method would not require eye and skin protection needed with the acid etch method. I also spoke with David Burleigh, Ph.D. (from MIT) of the Materials and Metallurgical Engineering department at the New Mexico Institute of Mining and Technology. He agreed with Dr. Dean, but added a couple items: 1. Corrosion could continue if there were road salts deposited on the aluminum 2. The sheets should be inspected for signs of pitting: pimples of powder above the surface. I think now Ill inspect the corrosion to make sure there is no pitting. At that time I could try removing the corrosion with scotchbrite alone. Most sheets have the stain on one side only. Ill mark this side so I can avoid the potential of recurring stain on the exterior. I give thanks to Dr. George Totten, author of the Handbook of Aluminum and past president of the International Federation of Heat Treating and SurfaceEngineering (IFHTSE). Dr. Totten referred me to Drs. Dean and Burleigh.

I have removed light corrosion marks and scratches with scotchbrite myself. Just one word of advice: you might not need hands and eyes protection, but I suggest some sort of dust mask, specially if you are going to use scotchbrite on a power tool. A thin, green dust (or whatever color you are using) will be created and get into your airways - it can't be good. I learned about it when I blew my nose after a session of "scotchbriting"...

Zenith's standard fuel supply setup is - as you all know - one aux fuel pump behind the fuel selector valve/gascolator. The aux fuel pump needs to "suck" the fuel over a rather long way from each tank through the selector valve and the gascolator. I am somehow concerned that it is more likely with this setup that vapor lock occurs, especially during takeoff (engine at full power). I don't want to install 4 aux fuel pumps at each wing fuel tank outlet. But what do you think about this idea: * 1 aux fuel pump at the firewall (after the gascolator, standard setup, ok for cruise flight phase) * 1 elec fuel pump at the left inner tank, switched on for takeoff and landings, takeoff and landings are made with fuel from the left inner tank. This would mean that during critical flight phases with high power settings, the fuel is additionally pressurized right from the wing tank by the wing tank pump. In case I forget to switch on the wing tank pump and/or forget to select the left inner wing fuel tank, the setup is still Zenith-standard (1 aux fuel pump at the firewall, 1 engine driven fuel pump). What is your opinion? I am not a fuel system expert - looking forward to reading your answers!!!

Looking at the drawings it appears there is no "real" up elevator stop on the CH-701. Down elevator is limited by the contact of the lower elevator horn against the rear of the fuselage, as noted in the drawings to "later: file to adjust elevator stop" (Dwg. 7H5). No mention of up elevator stop.

I have a question regarding rudder construction. In the workshop, the vertical tail horn, fairing, and the upper bearing are not installed. I know that we are supposed to wait to install the upper bearing until we install the rudder on the fuselage, to get the proper positioning. How about the tail horn and fairing - do we need to wait on those also, or can they be installed now? Also, I noticed that plans page 6-T-5 shows a fiberglass rudder fairing for the top of the rudder, (my plans page is dated 02/05). Is this an optional item, or should we have gotten a fiberglass fairing instead of the aluminum tip rib when we built our rudder at the Aug. '05 workshop? Our kit did not include this fairing, and it was not shown in the packing list.

I did not recieve the fiberglass upper rudder fairing either, when I called ZAC about it they told me it was completly optional. I left the aluminum tip rib in place. I have not attached the bottom rudder fairing or the upper bearing as of yet either, (I plan to wait till it is mounted on the fuse.) I did go ahead and attach the rudder horn though. Dont forget to leave a no rivet zone for your lower fairing untill it is mounted!! good luck Brad Cohen 601XL tail, wings done >From: "Dave VanLanen" >To: >Subject: Zenith-List: 601 XL Rudder >Date: Mon, 6 Feb 2006 21:12:22 -0600 > >--> Zenith-List message posted by: "Dave VanLanen" > > >We finally have our shop and tools ready, so we can start building. > >I have a question regarding rudder construction.
