    Tommy, I have vented caps on my czech 701. They work fine unless you put your cap on backward. THis will pull all the fuel from the other tank and than the engine quits. Hope you are high enough to go to full tank and start engine as the Rotax stops turning as soon as engine quits.

    Thanks for all the replies. A friend that works in a machine shop said they have a .252 reamer I can use. I just couldn't see spending $30 for those two little holes! I found out that 6.4mm {~.252} is a standard metric drill size and those cost about $2.

    Steve, Keep it mind, a reamer makes a very accurately sized, _round_ hole. The hole from a drill bit is only approximately round. They don't accomplish exactly the same result. I'm not sure about the application in this case, but if the roundness is important, definitely use a reamer. Dino On 4/17/07, Stephen R. Look <slook@mchsi.com> wrote: > Thanks for all the replies.

    From: japhillipsga@aol.com
    Ed, I found I could trip the latch from the ends with an ice pick from the outside. After you get it all adjusted and working you'll find the system reliable. Something I recommend you consider is to cut access holes on the inside side panels that corresponds with the cable adjustment nuts. I made three holes about 2 x 2 and made little thin cover plates with small pan head screws to attach. I 've had them off a couple times since completion. Going to Sun n Fun ? I'll get there in time for the Thursday bar b que. Hope to meet you there, Best regards, Bill of Georgia -----Original Message----- From: dredmoody@cox.net Sent: Mon, 16 Apr 2007 4:37 PM Subject: Zenith-List: Canopy ideas Hi Guys, I'm about 80% done with the canopy on my 601XL and I have a thought to share with the list. I recall lots of references to cutting a little oval slot in the inside flashing of the canopy frame to allow us to release the latch with a small screwdriver if the cable release linkage fails. I don't however recall anyone saying anything about access to release the latch form outside the plane in such a case. Of course, one could unscrew all the self tapping screws and remove the bubble from the canopy frame but I would like something simpler if the need arises. So, I've decided to drill a 1/4" hole through the steel plate between the rear bow tube socket and the latch mechanism and tap it for 5/16" x 18 threads to accept an allen socket set screw (to serve as a plug in the hole). The hole will be in line with the latch release lever to allow me to reach through with a small screwdriver to release the latch from outside the airplane. The set screw will seal the hole (with removable Loctite) until that access is needed, if ever. Since the set screw is only about 1/4" long, it will not protrude significantly from the side of the airplane, nor will it interfere with the movement of the latch release lever. The outside flashing will be back-drilled at 5/16" to align over the hole. The entire project adds no significant weight and costs about 70 cents. It could save a lot of grief ! someday if the cable linkage fails (like away from home base, for instance). I am also planning to make riveted (or screw retained) access hatches over the cable end adjustment fittings in the inside flashing on both sides for future cable slack adjustment. Why have the adjustment devices if we have no access to them, right? While I'm fairly certain that I'm not the first builder to do these little innovations, I don't remember anyone mentioning it for the list to consider. Anybody got other wonderful suggestions to consider before I rivet the canopy frame together in a week or so? Dred PS: After I woke up at 3AM a few nights in a row, I finally got the mental picture of what I needed to do to properly adjust the side frames, the rear bow tube sockets and the rear bow itself. After that I didn't feel like cussing every time I looked at the canopy frame. It was sort of like a twelve step program for amature aircraft builders. I feel much better now, thanks. ________________________________________________________________________

    Dino is right, the purpose of a reamer is roundness of the hole and a very smooth finish. I bought the correct reamer for about $15.00 through MSC.

    Subject: corvair mechanical fuel pump
    Ok guys Ive read some more of the history on this. Both on the corvair and the zenith lists and I have come to the understanding that the reason for not utilizing the corvair mechanical fuel pump is because of pump failure and failure mode. My understanding is that when it fails it can dump fuel into the case causing problems. I have had a pump failure on my old 225 car engine. In that case the diaphragm started to leak. The mechanical part of the pump was fine. I am assuming the corvair fails the same way. Now, for the question. Is it possible to rebuild the mechanical pump with a more modern material and avoid the failure? By the way, I am assuming that when a mechanical pump fails that a back up electrical pump can still push fuel through it.

    I would think that a failed fuel pump could pump fuel into the crankcase and also into the engine compartment( huge risk of fire). Also if you put an elec pump in line before the mech. pump, you would just push fuel out of the hole that caused it to leak in the first place.

    There is also the issue that there isn't a magneto system on the Corvair so if your power system fails the engine is going to stop working anyway.

    It's possible with a major redraw of the entire design, but it is not a simple task. I also think Zenith (or Chris H. anyway) is out of the major modification "review" business so you'd be on your own for your revisions. Not something I'd recommend...

    Subject: Re: Canopy ideas
    Great think alike Bill. I just cut 1.5" diameter holes in the inside flashings and made square covers for them the covers will be secured by four small pan head sheet metal screws. I though, "Why have cable adjustments without access to use them?" What I did for emergency opening from the outside is I drilled and thread tapped a 5/16" hole on each side through which I can poke the latch open. Normally, a allen socket set screw will occupy that hole to seal out bugs and rain. Regretably, I will not be at Sun N Fun this year. Got too many "really important" things to get done here. You know how that goes. I'm working fairly steadily on the plane and I'm building a new hangar for the ultralight and the Zodiac.

    Subject: Long range tank fix
    hi list i just finished countersinking the neck of my fuel tanks. they were welded to long and would not let the gas cap screw in enough for a even fit with the nose skins. It was pretty simple after i learned how to do it on the first wing. the directions say to turn the sink slowly. that really means slowly. they sent an electric motor to use and slow is very hard to get. i just pulsed the motor on and off and never let it get up to any speed. put a lot of pressure on the drill motor and as you pulse and it begins to bind, just let off. the first counter sink took about two hours the second (using the above procedure) took about 15 minutes. Zenith was really on top of this and i am quite pleased with the service. they even sent the Scotch-Brit and the WD 40. I still plan to have the edge of the gas cap assembly fit on top of the wing skin. it will be up a little, but will be very clean looking. i really don't like the looks of the recessed caps, especially the way i cut the holes regards john butterfield 601XL, Corvair torrance, ca __________________________________________________

    Subject: Help. Need ACS fuel caps
    I have a HD with the full size wing tanks. The tanks have a 2 5/8" opening for the fuel cap. They are designed to work with the ACS flush mount non vented fuel cap. I just noticed Zac sent me the header tank fuel cap style instead of the ACS ones. Now here is my problem. Acs changed the design of the fuel cap. The new one will not work. I need the old style with a rubber puck gasket. I can't find the old style anywhere. If any one has some I will pay top dollar for them. My tanks are already installed with the holes cut for the fuel caps in the leading edge wing skin. If I can not find any ACS caps I will have to cut out the 2 5/8 collar, weld in a patch and install a different cap system, plus most other caps are smaller so the hole in the leading edge skin will be oversize. It sure would make things simple if I could get my hands on some of those caps. Maybe I should go to Sun N Fun and help myself to some by the 601 flight line.

    Thanks for the feedback. Sticking to the plans is a point well taken. I only plan to deviate if I get factory permission and for necessary items. For example I asked about adding a beacon to the top of the rudder and for some small holes in which to spray Corrosion X after construction.

If indeed this is the case, has anyone developed an auxiliary ignition system that would allow one to hand prop/start the engine? Would hate to be caught out in the boonies, on the ground, with a dead battery. George Working on the left wing. CH-701 N73EX (reserved)

    Subject: Re: Help. Need ACS fuel caps
    Hi Frank,=0A =0A I have an HDS with LET's. I replaced the older style caps (Top hat style gasket) with the new caps with "O" rings about a year ago and still have the old caps. The reason I replaced them is because the top hat gaskets swell after a while and are hard to remove/replace. If I reme mber right the new ones did not fit the holes very well so I took them apar t and turned down the O D's until they fit. I also turned the top edges to blend them to the top skin better. I don't know what type of set-up you ha ve or why the caps do not work. I will attach a picture of my new caps.

    Subject: Re: Adding Duct Tape to the Toolbox (601HDS Ribs to Spar)
    As requested, here are photos and an explanation of how I used a roll of duct tape to drill the nose and rear ribs for the HDS: 1. Mark the rivet lines on the spar using a Sharpie, being sure to go over the extrusion on both top and bottom. 2. Mark the center line of the nose and rear ribs on the outer flanges. 3. On the inside portion of the flange, using the marks in Step two as a reference, make a tick mark on the rear flange where the rib will join the spar. This will be used to line up the rib with the marks made in Step 1. 4. Tear off a piece of duct tape about the same length as the rear flange of the rib. Place this within reach of each rib station. (I simply stuck it by a corner to the edge of the workbench) 5. Using a speed-square against the spar, line the rib up with the rivet line on the spar, using the marks made in 1 and 3 above. 6. With your finger or a small screwdriver, make sure the tape has stuck and is tight along the edges where the rib meets the spar. 7. Take a small board (I used a scrap piece of wood) hold this against the rib flange and drill out the pilot holes. It takes longer to describe that to do it. As explained in the manual, do this first for the nose ribs (using a #40), through the web. Then remove the nose ribs, attach the rear ribs, and repeat using a #20. Photos attached. I thought I had used yellow duct tape, but it appears it was your standard gray. RR-Duct1 shows the speed square and alignment of the rear rib with tape applied. RR-Duct2 shows a close-up after the holes are drilled. Note the small tick marks on the flange that aligns with the spar line. It looks off in the photo, but that is because of the angle. NR-Duct1 shows a Nose rib duct-taped and ready to go.

With experience come knowledge, and a little luck. One thing I have to share, since I haven't seen this "method" in the archives, is the method I used to attach and hold the nose and rear ribs yesterday while I drilled the pilot holes through the spar. On the right wing, I used the system outlined in the builder sequence manual with the clamps, etc. It worked but took me a long full day to do by myself. As I was looking at the next wing yesterday, it occurred to me, why not just tape them on! I grabbed my handy-dandy roll of bright yellow duct tape, lined each rib up along their rivet lines, checked with a square and taped them down by running a piece of tape along the rib flange to the spar. I taped all the nose ribs first, drilled the holes, removed them, taped the rear ribs in place, drilled them, and finished the whole process in well less than an hour! Duct tape held like a champ, and came right off with no residue (although I cleaned it just to be sure). You do have to watch and make sure they don't slip off their lines, but none of mine moved as long as I used a backup block held behind while drilling and I made sure the tape was securely attached. I think I've found a new builder's friend!

    Subject: Visit to Holland
    I will be visiting Amsterdam and other locals from April 25-29 and was curious about the Zenith folks that may be in that area. I will be occupied by business until the 27th and have two days to myself before my return flight to Houston on the 29th. If anyone would like to get together and share a meal or even let me drool over their project or plane that would be great. I am curious what the flying culture is like in Europe and am hoping to poke around a bit. Please reach me by email at mrcc1234@sbcglobal.net if you are willing to get together.

    Subject: spray foam insulation to secure l.e. fuel tanks
    Has any one ever tried this? It would seem like a good way to make sure the tanks don't move and rub. There is the stuff for doors and windows. It does not expand. Put some in between the tank and ribs and the spar. The only concern would be some kind of a corrosive effect on the aluminum.

    I live in Almere. that's about 10 minutes drive from Lelystad. Jorgen Verroen is at EHLE with a hanger full of Zeniths, including two lovely Czech built 601's. If you need a ride to the airport just give me a call when you are in Amsterdam.
