Depending on how much adjustment is available, you can stack sheets around the shoe to get any radius necessary. -- Bryan Martin N61BM, CH 601 XL, Stratus Subaru. Airframe construction complete.

Clamp that in place instead of the aluminum angle and make your bends. It works perfectly and you can keep the original piece intact in case you need to bend a sharper corner on some sheet steel someday... I made a larger bending brake out of wood and used the maple for it - see http://www.murrayjohnson.com and go to the Tools section.

I'd like to replace the fuel filter on my facet pump with a glass tube boat fuel filter, further upstream. Is the facet pump likely to expeience any problems with this? Is the existing filter particularly fine? I don't see the point of 2 filters in line so the facet filter will have to go..

If the hold down piece is movable and adjustable, take a file to it. Chris H. recommends it in his Zenith brake plans. If the piece can't be moved. Wrap it.

Its seems most of the large trailers that you can haul behind a pick up are about 2" too narrow between the wheel wells. Taking the wings off is about an hours work...too much to NOT keep you're a/C at the airport I think. I would not attempt to trailer it on its landing gear.

Ultralight airplanes were using them quite e bit several years ago, but the glass tube types were prone to coming loose and leaking fuel or sucking air. One more failure mode to deal with.

My aircraft is built and I have no idea how easy it is to rig and derig it=A0 but I have seen references on the net to trailers. My only experience was moving our 601 HDS from our home in the mountains to the airport, some 60 miles away. 4" X 4" wood chocks were lag bolted to the 8' X 16" wooden trailer bed for the main gear, tail tiedown secured to rear of trailer, and nose gear tied to front of trailer provided more than adequate security for the aircraft. We could only get one wing in back of the Suburban so had to make two trips to the airport to get the other wing there. This would not be necessary with proper wing racks fabricated for the trailer. One problem is raising the front of trailer high enough so that tail does not scrape as you go up the ramp onto the trailer. A tilting trailer bed would obviate this problem. EAA chapter members cautioned against damage being caused by rough roads so we drained all fuel out of nose tank and avoided any bumps. The aircraft road very well up to 50 mph and we probably could have gone faster. Loading the trailer and reattaching the wings is a two-man operation. A well coordinated crew might be able to do the process either way in two hours but our first on and off operations probably took at least 6 hours each. The bottom line is that it could be done but would be very time consuming. =20 Rerigging the ailerons each time would require a test flight if it were a certificated aircraft so that would be a good procedure to follow. Overall I would not recommend it.

I've never removed much debris from it in 6 years of operation because I transfer 92 octane mogas from my truck for most of my flying; I have a fuel filter on my truck pump. Even after flying to OSH in 2001, where I had to use 100LL, I had almost no load of debris to remove. During my annuals I pull the carb bowls and inspect them, of course. I've never seen anything in the bowls, despite the fact I like Teflon pipe tape as a sealant. Consider the risk of high heat inside the cowl on the endseals of the little glass dudes. GGP ________________________________ Message 11 ____________________________________ Time: 10:49:30 AM PST US From: "Dr. Perry Morrison" Subject: Re: Zenith-List: facet pump fuel filter --> Zenith-List message posted by: "Dr. Perry Morrison" Thanks George, I use a great water/debris trapping funnel into the jerry can and again into the plane whe I fuel up. My fuel line filter isn't in the cowl. It's on the inner fire wall just underneath the front tank so heat is not a problem. Again, in 100 hrs I've never had a drop of water or anything, but the glass filters I have in mind are "worth" enough to have refurbishment kits. A friend of mine has 2 and they haven't missed a beat in 400 hrs. My main concern was whether the facet pump relies on the finer filtration provided by the metal filter it seems to come bundled with? Or is it more robust than that? Looking at these glass filters I'd say they were a little coarser.

If a filter upstream starts to clog, your pump will draw a vacuum on the inlet line which can lead to vapor lock. Your pump can push fuel through a partially clogged filter much easier than it can suck through one. With a filter downstream of the pump, the fuel is always under pressure and much less likely to vaporize in the line. -- Bryan Martin N61BM, CH 601 XL, Stratus Subaru. Airframe construction complete.

I bought mine from Shirley at Zenith in Mexico MO. about $20.00 but you can see, if not the same, a very simalar 48 inch set of brake plans at http://www.vansairforce.org/tools/index.shtml I also bought the 8 ft brake plans from our own Larry M. And they are a great set of plans. It just looked to complicated for me to build. I did end up building a 6.0ft brake that does a great job. the plans came from a series of pictures from a Sonex builder. Not plans really. He built a 10 ft version!!!!. I shortened it down to 6.0 ft. Costs about $80 and took a weekend to build.. And I am really happy with it. So far there isn't anything I haven't been able to bend on the 701 that I needed to. But I haven't tried. the .040 longerons either. It will bend accurately 48 inch of .040. I haven't tried 6.0 ft. It will also make box bends as well, with shorter pieces of angle iron. I bent up my wing tanks before I took and had them welded. Btw before you think I am full of it. Ian's brake doesn't look anything like anyone elses brake. Its slow to operate, clumbersome to adjust. but does a good job and is easy to build if you can weld 1/4 inch mild steel. No machine work I don't have Ian's link anymore but someone that knows about Ian or is building a sonex might.????? If you decide to go with Ian's brake, and are building a 701 need to make it a little longer than 6.0ft. I believe (may be wrong) but the longest piece we need to bend is the Elevator spar, and its longer than 6.0. When It warms up. I am going to rebuild my brake so that it accepts this 701 piece. Hope this helps.

HEY THEY ARE WING SPARS....someone said they were important. I wouldn't know yet!!!! SO I didn't want to mess up those solid rivets, I am not any good with an air rivet gun. LIKE NO GOOD PERIOD, dangerous in fact. :-) BUT found this article from the late Tony B. last month http://members.eaa.org/home/homebuilders/authors/bingelis/ Metal Spar Assembly Tips down near the bottom of the page. Talks about making a hand set tool from an arbor press. I ordered 2 squeezer end sets. 1/8 and 5/32 for 8 dollars from the YARD STORE. Drilled my 3 ton arbor press turn table. (hey its the one I had) And hand set some rivets over the weekend. Works GREAT I MEAN GREAT!!!!!!!!, how come no one told me about this a year ago!!!! I don't care what the manual says you can't hit them da** rivets with a hammer, you have to use a punch, and the 5th one I did it jumped off and nicked the alum angle!!!!!! And btw when you order those squeezer end sets. Order their dog leg deburring tool with end bit for $18. You will throw that other crap away.

What have you with transponders done in this regard or does one assume that the thing is suppose to work directly "out of the box"? Larry C.

An avionics shop has the test equipment to calibrate it and might be what you need to do. Some encoders like the Rocky Mountain microEncoder will read the altitude being squawked by the encoder. It will have to be certified every two years anyway. If you ever use flight following or file IFR, you only get altitude plus or minus 100 feet before violating regs, so if your encoder is even off 50 feet, it puts you at the edge of your assigned error. Even if you don't fly into controlled airspace, the TCAS reporting system in commercial planes will read your error and give evasive instructions to the pilot based on your squawk altitude, not your real one.
