    From: "Hunt Malcolm" <Malcolm.HUNT@networkrail.co.uk>
    --> Zenith-List message posted by: "Hunt Malcolm" <Malcolm.HUNT@networkrail.co.uk> Sorry not to have replied earlier but been away on business. I think a previous response from me on Avex rivets is on the archive but the following give clear directives from Zenith. Plan revision 06/02 to 01/03 changed the Avex rivet prefix from 1682 to 1604, Textron the manufacturers advised this was a change of protection to the steel mandrel. Zenith therefore have precisely specified the rivets to be used. In the Heintz Textbook 'Riveted Joints Part 2 of 2', see www.zenithair.com/kit-data/ht-87-1.htm1 Chris makes it clear that English manufactured rivets are to be used as those manufactured in New York and Brazil do not have consistency. All is not lost as Avex now manufacture in China! and in the Zenair News #147 of March/April 2005 'Memo from Chris' gives details of a test rig and loadings of A4=50kg (110lb) shear and A5=80kg(175lb) shear. Well worth a look at.

    Subject: oil pressure fluctuation
    --> Zenith-List message posted by: "Johann G." <johann@rafpostur.is> Hello list members. I have been experiencing some oil pressure fluctuation. I found a possible solution to the problem which is to put a washer under the spring of the bypass valve. Can someone help me with the location of that valve? Is it in the oil pump on the bottom? There is a spring in the parts catalog from CPS where they show a picture of the pump from Rotax. It is #3 and the nut or cap is marked # 5. Can this be the cap nut that needs a washer? Thanks in advance, Johann G. Iceland. Z701 27 hrs flying.

    Subject: Real Aileron Dimensions
    --> Zenith-List message posted by: "William J. Naumuk" <billn@velocity.net> All- It took me a month to the day to figure out the dimensions you need to build an HDS aileron, since the plans are a total mess. Zenith was no help- they just kept recommending that I buy factory parts. This was after my original kit parts didn't work! Everyone should take the time to read this posting, to give you an idea of how patient and analytical you should be in order to give yourself the best chance at successfully completing your project. If I weren't absolutely sure of my findings, I wouldn't throw myself to the wolves. There is no grey area- if you don't believe me, try building a good aileron to the rev 4 prints! No updates are offered at this time. Start with the skin blank. There are 3 different possible layouts, two on 6SV-3 and one on 6-V-10. 6SV-3-1, with one change, will give you the lightest skin while meeting all of the other dimensional requirements. Instead of a 485mm DL, you want to go with 475mm. If you don't (Which was the way I went) you wind up with a 30mm Z spar flange instead of the required 20mm. I wasn't going to spend $125 in materials and subcontractor's fees to save a couple of ounces extra weight. I lucked out here. Second, the Construction Manual is actually correct for once. To set the 11 deg root rib (And eventually, main rib) angles, measure in 38mm from the I/B Z spar edge instead of the 43mm shown on 6SV-3 and 6-V-10. This is where double checking each assembly with it's mating part will save you. Something didn't look right, and my protractor proved it wasn't. All this cost me was some alcohol and the time it took to remove the 43mm lines and replace them with the 38mm lines. Finally, the tip rib. I laid out the print full size in AutoCad, cut the rib forms on my table saw, and fabricated a rib that was well within 2mm of plan dimensions. It was almost 3/4" short of meeting the trailing edge! I triple checked everything, and had extensive correspondence with Nick. No help. So I went ahead and very carefully laid out, cut and filed the O/B end, then made a cardboard tracing of the opening. Then I transferred the tracing to AutoCad using just the vertices for the main dimensions and adding the rivet flanges. The plans call for a tip rib 160mm vertically from the hypotenuse, 95mm opposite, by 140mm at the adjacent. I wound up with 163mm x100mm x 160mm. The couple of mm difference in the hypotenuse and the opposite are no big deal, but the 20mm difference in the adjacent was the culprit. 20mm .787", or roughly 3/4". Better archive this one in case there are still some HDS builders out there. Like the sarge on Hill Street Blues used to say, "Be careful out there". Bill

    Subject: Re: rivets
    --> Zenith-List message posted by: Tim & Diane Shankland <tshank@megsinet.net> Paul, to answer your question about the specifications on the rivets used , this is from the Avidel Technical data sheet. part number 1682-0412 1/8 grip range .093-.250 Single Shear 155 lb Ultimate Tensile 205 lb. part number 1682-0514 5/32 grip range .109-.312 Single Shear 225 lb. Ultimate Tensile 300 lb. The wild card here is the head, all these specifications are with the counter sunk head from the factory. There has been much discussion on the list as to the effect of modifying the head such as we do. Whether it strengthens or weakens the riveted joint? The fact that there is no specification as to the exact profile of the formed dome head means that there is a great variation in head shapes made by the various builders modifying their rivet pullers and thus a potential great variation in pull strengths. Since Zodiacs are not falling from the sky with their skins unzipping at the rivet lines would indicate that there is considerable margin in the design. As for those "special rivets" from Zenith from that "special" factory in England the distributor I buy my rivets form confirmed that all rivet production is now in China.

    Subject: Re: Installing nose wheel bungee
    --> Zenith-List message posted by: JAPhillipsGA@aol.com Craig, yes and no. Is your engine mounted? If not make a tool from a steel pipe where you grind out the lip into an oval (football shape) and pry it up and on the forward shaft. With the weight of the engine all I had to do was take off the round retaining plate at the top of the gear shaft, jack up the front of the plane to lower the gear shaft and it slipped over the forward shaft. Then I lowered the front of the plane slowly letting the engine weight stretch the cord and guided the top of the gear shaft through the green plastic bushing plate and the firewall top cross beam. Was not difficult job at all. Best luck, Bill

    Subject: Pre-Heating a 601
    --> Zenith-List message posted by: "Craig Payne" <craig@craigandjean.com> What about an engine block heater? I don't know if your plane is parked close enough to an electrical outlet. I found these on Aircraft Spruce that adhere to the oil pan: http://www.aircraftspruce.com/catalog/eppages/ezheat.php But if you have a Rotax I don't think these will work as the Rotax has a dry oil sump. A related product is a battery blanket (also electrical). Warms your battery for more cranking power. http://www.jcwhitney.com/autoparts/Product/tf-Browse/s-10101/Pr-p_Product.CA TENTRY_ID:2006128/showCustom-0/p-2006128/N-111+10214+600010588/c-10114/TID-8 014524 If you are not near a source of electrical power all I can suggest is a small radiant heater. There are some that are small enough to run off of a propane torch bottle. But that would mean that you would have to remove some cowling to point the heat at the block. http://www.rei.com/online/store/ProductDisplay?storeId=8000&catalogId=400000 08000&productId=6077481&parent_category_rn=4500640&vcat=REI_SEARCH -- Craig -----Original Message----- From: owner-zenith-list-server@matronics.com [mailto:owner-zenith-list-server@matronics.com] On Behalf Of Jim Pellien Subject: RE: Zenith-List: Pre-Heating a 601 --> Zenith-List message posted by: "Jim Pellien" <jim@pellien.com> Larry, My aircraft is not hangered.

    Subject: Re: Pre-Heating a 601
    --> Zenith-List message posted by: Larry McFarland <larrymc@qconline.com> Jim, If you've got access to electricity, it'd be a minor matter to make a weatherproof shell for keeping wet and wind out of the heater that would reach up a little further under the cowl. It would need a set of wheels 2-foot ground extensions for stability and a weather proof cord all to keep wetness out but it could be done. Nice thing about this type of heater is that if it gets kicked over it shuts off too. If the winds get nasty, you could even stake it down. Then you'd have to plug up your cowl but for one screened opening on the bottom to keep the field mice out of it. Don't give up on it. I think you could do it, if you have a plug-in somewhere close by.

    Subject: Re: Installing nose wheel bungee
    --> Zenith-List message posted by: "Dave Zilz" <z4t143@hotmail.com> I'm not sure how the XL nose strut works, but I'll explain how I did it on our 801. I used the tire iron from our car jack as a lever. I got the bungee installed on the aft hook and wrapped around in prep for stretching onto the fwd post. Since that fwd post is an open tube, I placed the tire iron through the end of the bungee and inserted it into the open tube. This arrangement allowed me to lift the tire iron and stretch the bungee until it was on the edge of the fwd post. From that condition, it didn't take much to persuade the bungee onto the post. Sounds simple now, but I do recall wrestling with it for a bit. Be careful! There is alot of energy stored in that stretched bungee! Hope that helps!

    --> Zenith-List message posted by: "Randy" <rpf@wi.rr.com> Jim, I used a block heater system, from www.reiffpreheat.com that you epoxy to the bottom of the block and a cylinder band heater that I put around the oil tank. Put a blanket, or something, over the cowling to cover up the air inlets and the system works very well.

    Subject: Re: oil pressure fluctuation.
    --> Zenith-List message posted by: Gary Gower <ggower_99@yahoo.com> Hello Johann, Is the oil pressure electric? I will first check the pressure with a phisical oil instrument, carefully installed temporary, preferable if possible outside the cabin... Probably the fluctuation could be from a faulty conection to a faulty sender or instrument. In my case I will first be sure that the instrument is working OK before moving forward with the engine...

    --> Zenith-List message posted by: Gary Gower <ggower_99@yahoo.com> Hello Larry, I liked you idea since last year... This is a Off hands point of view, for shure here we dont need a heater for the engine, But how about installing another hose from the engine cowling the the inlet of the heater... this air circulating could lower the use of the heater. Less electricity used... Well, probably will not be worth it... Saludos Gary Gower.

    Subject: Installing nose wheel bungee
    --> Zenith-List message posted by: "Craig Payne" <craig@craigandjean.com> Thanks! I did a variation on your idea by using a pipe over the outside of the stub (as suggested in two responses). I made a 45 degree cut at the end of a piece of conduit that was about 18" long. The longer part of the cut will hook over the top of the stub even when angled down at 45 degrees to catch the end of the bungee. Then you just raise the far end of the pipe while pushing the bungee along the pipe towards the stub. Cutting the end of the pipe or typing up this description took longer than getting the bungee on. -- Craig -----Original Message----- From: owner-zenith-list-server@matronics.com [mailto:owner-zenith-list-server@matronics.com] On Behalf Of Dave Zilz Subject: Re: Zenith-List: Installing nose wheel bungee --> Zenith-List message posted by: "Dave Zilz" <z4t143@hotmail.com> I'm not sure how the XL nose strut works, but I'll explain how I did it on our 801.

    Subject: 912S engine installation in 701
    --> Zenith-List message posted by: NYTerminat@aol.com List I am installing a 912S in a CH701 and have a question on the coolant line routing. I have the Firewall Forward package from Skyshops ( Czech Works) new style cowl. The drawing 7-E-13Z shows two different hose routing connections for the 912 and the 912S. The 912 has the bottom of the radiator connecting to the water pump and the 912S the bottom of the radiator connects to the top expansion tank. Why would there be a difference? Does it matter which side connects to the bottom of the radiator? One of the problems I am having is that the coolant hose that was supplied has very little flexibility to bend without kinking. It almost has no ability to bend. It would be better to route them as the 912 shows .Has anyone had this problem? Is there anyone that has installed the newer style cowl on a 701 with the 912S? If there is could you contact me as I have some other questions/concerns. I have seen that blue coolant hose on other peoples planes, where do I get that and does it bend well? The hose that I have is black, it is called Semperit FKD Kuhlwasser/cooling water 25x3.5. On the photo's that I got from Skyshops they show short pieces of hose connecting to aluminum preformed pipes. All I got was a length of hose. I look forward to hearing from you guys Thanks Bob Spudis Ch-701/912S frustrated
