Just a note, i called Zenith last week to find out the lead time on the wings, and it was quoted at 12 weeks. My point however is the cutting of the elevator for rudder clearance and the trip tab. I made a mess of the rudder cutout and tried using an air grinder with a 3" cutoff blade. I was shocked at how easy the trim tab cutout went and how clean the cuts were. I will trim the rudder cutout tomorrow and expect the lines to be perfect. I wish I knew about this before as the time saved and the quality of the cutouts cannot be matched using snips. hopefully there is no problem using the cutoff blade as it was a real pleasure to use. If there is a problem, i would like to know it, and if not, try a cutoff wheel. Use eye protection. I was surprized that I could actually make the cuts within a half a mm,as the size of the blade allows for really accurate lines. waiting for wings. john butterfield 601xl ________________________________ Message 2 _____________________________________ Time: 12:27:43 AM PST US From: "Richard McLachlan" Subject: Re: Zenith-List: Re: Matco brake reservoir --> Zenith-List message posted by: "Richard McLachlan" When we needed to fill ours, we borrowed a pressure filling device from the local airfield maintenance place. The fittings are exactly the same as used on Cessnas etc. You just clip it on to the nipple, pump up the reservoir on it and squeeze the trigger. Presto, the brakes are filled from the bottom in about 10 seconds. As usual, having the right kit makes the job really easy. I think we gave the guy the price of a beer for the short loan. ----- Original Message ----- From: "Bob Miller" Subject: Zenith-List: Re: Matco brake reservoir > --> Zenith-List message posted by: "Bob Miller" > > Larry, > Many thanks.

Either vent it to the atmosphere or to the wing tanks. To prevent trapping air or water in the fuel lines or vent lines, the lines should run downhill all the way to from the wing tanks to the header tanks with no low spots or high spots. This will allow all liquids to run out the lower end and all air to bubble out the upper end. on 2/25/05 3:11 PM, owner-zenith-list-server@matronics.com at owner-zenith-list-server@matronics.com wrote: > Thank you very much for the information.

I can never get below 3-4 times and in some assemblies I have seen them built on the table and then into flat pieces on the table over 7 times before I could actually stick a final rivet in. So yes it is standard procedure. Wife laughs at me now. But the first time I was so proud to have the wing all assembled one night I dragged her out to have a look, next morning when she came into garage she saw it all dismantled, I got very special treatment all day, pampered like a child till she finally asked what went wrong with the wing and I told her NOTHING is wrong I had to take it apart to Chromate it. Almost had to couch it that night!

As for the blade, I have cut most skins in my scratch built 601XL with the same blade, about half way through I switched the ends over as it has cutters on both ends. David has used this knife to shear up to .060 with no problem. .025 takes about 4 scores for me and about 6 for David before it cleanly shears off the metal. ( I weigh a bit more then David and can use my weight to apply pressure to the knife). Pick one up and give it a try. Once you have used it you will not go back to any other method, not because it is the easiest method but simply because you can achieve the same result with the Olfa P-800 that you can get with a 12 ft shear. Access holes are self explanatory in the Olfa's usefulness. I found this info on the web Olfa P-800 Plastic Cutter This heavy-duty plastic and laminate cutter is designed as a scoring tool for sheet plastics and laminates. Use it to produce a very fine score line allowing for precise breaking. It features a reversible tungsten blade with 2 replacement blades in the handle.

Better to pay the tax for parts as you build or once on completion than have to pay a tax on the purchase of a new aircraft on registration later as well. The inspector will be satisfied with closed pieces if you record your work digitally before you close.

I got a hold of some variprime. I had been using Acid etch, Alodine, and then paint cans. It wasn't too bad but the Variprime is much easier. I really like it. You mix equal parts of an etching agent and the paint. I then shot it with a HLVP touch up gun I got off of Ebay. It really turned out nice. Just about out of parts and the Elevator should be done tomorrow. Will pick up the rest of the kit in about a month. Time to clean up the shop and do some Honeydos.

I'm building a 701 with an 80 HP Continental which needs no boost pump or engine driven fuel pump. I'm torn between: 1) Plumbing my wing tanks directly to the gascolator mounted low on the firewall, Cessna style, or 2) Plumbing the wing tanks to a small liter sized header tank mounted high on the firewall. I would route the incoming fuel to the bottom of the header tank and vent the top of the tank to the top of both wing tanks. Fuel would go from the bottom of this small header tank to a shut off valve to a gascolater and then to the carburetor. I'm unsure of the details but believe Super Cubs have a similar system. In either case I would definitely use 3/8 in. tubing with no smaller restrictions. A friend suggested that the small header design may work best in the 701 because the 701 like the Super Cub is capable of a very steep climb angle which, in conjunction with rapid acceleration of the aircraft, would reduce the ability of the wing tanks to provide fuel. The header tank with its short fuel line and better placement relative to the carburetor could supply the engine until the angle of attack is reduced. I think it is important to vent the header tank to the top of the wing tanks rather than to atmosphere to ensure that the vent pressure on the wing tanks is equal to the vent pressure on the header tank so that flow can't be disrupted by different pressures. Any advice is welcome and I'd particularly like to hear what fuel system configuration other Continental owners are using in their high wing airplanes. Thanks, Dave, 90% 701 with Continental ________________________ Message 1 _____________________________________ >Time: 02:11:53 AM PST US >From: "Johann G." >Subject: Zenith-List: fuel lines in 701 > >--> Zenith-List message posted by: "Johann G." > >Hello list members. > >I am about to connect the fuel lines from my wing tanks to the D tank >under the >dash. >This tank has three inlets on the side, one on top side and two on the bottom. >Then there is the outlet under the centre. >My question is, if I use no fuel pump from the wing tanks and hook the >fuel lines >to the bottom two inlets, will the fuel flow uninterrupted with the gravity >force only?
