      If I remember, Aircraft Spruce sells the US version of
      the rivets.  Not the UK version specified by Zenair.
      
      I bought mine from Avdel Textron directly (in
      Toronto).

      Hi Listers,
      Thanks for the info re resupply of rivets.  I bit the bullet this am and
      called ZAC and ordered them from there.  They cost a bit, but will be at
      home with their genetically similar brothers in the rest of the plane ;< }
        While I was at it I touched base for some tech support and that made me
      feel better too.  They seemed as excited as I am at the prospect of another
      ZAC plane coming to life in the near future.
      
      Thanks for the help.

      While I was building my 601, Iadded some A4 rivets to an order. They were domed
      rivets, the same size as the A4 and seemed to be interchangeable.  To be on the
      safe side, I used them for the skin over the instrument panel. They were fine
      until I switched to a front hinged canopy. When I tried to drill them out,
      I hit the retained stem which deflected the drill bit, making a mess. I had to
      drive out the stem before drilling. With the regular A4, the head just rips off
      onto the drill bit and you can pull out the body without messing up the hole.

      Looking through the AS&S catalogue I see many designations of aluminium
      tube. The cheapest and best known to us ZAC builders is 6061.
      
      I see a 1" tube at .035 wall thickness at $1.33 per foot (old catalogue).
      
      Can someone tell me if this is thick enough (I assume one can crush a 1"
      plumbing olive...brass ring on the ends using copper pipe fittings to make
      the rubber hose connections secure)?
      
      Anyone tell me how much I need to order to get the rear of the rad at the
      trailing edge of the wing?
      
      I am planning on moving the rad first, looks like I will have to drop the
      front down to allow the 90 deg hoses to clear, and then making a statc
      pressure recovery scoop later that will fit over the outside of the rad,
      fixed to the underside of the fuse.
      
      I will get around to the second part ot "some point"...:)
      
      Thanks

      Frank,
      I just ordered 3 pieces of 1"-.049-wall 6061-T6 from Wicks that total
      12-feet.
      (12' is minimum order) and am comfortable with that.  The radiator is 38"
      rearward
      of it's normal position and intend to use about 36" or more of the tube to
      reach the elbows
      at the firewall.  Also, re-positioned the radiator front end 1" down from
      its normal position between
      two .040 angles, 20mm x 24mm, 65-1/2" long to reach from the rear spar to
      the firewall.
      I really like the appearance of the radiator back there, but I punched the
      angles before hanging
      them so the radiator can also be readily moved forward if something requires
      I retreat from this.
      We all seem to be on the same wave length (cooling issues).
      I'm compiling a set of parameters that have direct impact on getting the
      engine
      cooler on hot days.  Lot of research................

                Zenith will sell in low quantity, and at .08 and .09 cents each 
      verses .12 cents from ACS.

      Be careful in using aluminum tubing for something as important as the cooling system.
      Aluminum cracks from vibration and flexing very easily.  I think that
      George learned this the hard way with his oil pressure fittings a while back.

      I am planning on moving the rad first, looks like I will have to drop the
      front down to allow the 90 deg hoses to clear, and then making a statc
      pressure recovery scoop later that will fit over the outside of the rad,
      fixed to the underside of the fuse.
      
      I will get around to the second part ot "some point"...:)
      
      Thanks
      
      Frank

      Nope...then again I tend to be cheap!...:)
      
      Good idea though, I might even have acces to a beading tool here at work.

      I have been assuming that a radiator shop could bead the ends of a 1.00 dia.
      tube. Have you checked this out already?

      Larry/george/frank::
          Several comments..1. I got a 1 1/4 x 6' length tube at home depot..al.
      has worked for 5 years so far!!.Absolutely !! put bead of some type on each
      end of tube !! on my first flight, had very tight  2 clamped hose blow off
      tube..so don't think of not beading some way..( I was lucky to be able to
      borrow a beading tool from my local a&P SHOP ) 2.I get the impression you
      guys are just hanging the rads out in the breeze..don't think it will make
      much difference where you put it if that's all you're doing..there has been
      many excellent articles on rads/cowlings/placements/ect in Contact,RAC/ect
      would  suggest you take a look at these articles...thgere's some science to
      getting flow into and thru rad..( I was supplied a good cowling/rad as part
      of my engine package ..NSI ) so I just had to get the location that allowed
      good relative flow into/thru rad, and exit to low pressure area to solve my
      problems..I'll try next trip to A/P to get some photos to post if anyone is
      interestered..drop me a note and I'll sent photos so I don't clog up net..

      Thanks Larry,
      
      If I remember rightly there is only one 90 deg 1" to 1.25" transition rubber
      elbow in the original ZAC kit. The other connection is a stright "inch to
      inch and a quarter" transition.
      
      Did you buy a second rubber elbow and how did you find one with the size
      change?
      
      Are you bending a 90 deg elbow in the alu tube to reach the original 1"
      rubber hose? If not how are you connecting these?
      
      I assume you have not flown this new configuration yet?
      
      Thanks
      
      Frank

      Frank,
      I just ordered 3 pieces of 1"-.049-wall 6061-T6 from Wicks that total
      12-feet. (12' is minimum order) and am comfortable with that.  The radiator
      is 38" rearward of it's normal position and intend to use about 36" or more
      of the tube to reach the elbows at the firewall.  Also, re-positioned the
      radiator front end 1" down from its normal position between two .040 angles,
      20mm x 24mm, 65-1/2" long to reach from the rear spar to the firewall. I
      really like the appearance of the radiator back there, but I punched the
      angles before hanging them so the radiator can also be readily moved forward
      if something requires I retreat from this. We all seem to be on the same
      wave length (cooling issues). I'm compiling a set of parameters that have
      direct impact on getting the engine cooler on hot days.  Lot of
      research................

      For what it's worth, when I moved my rad to the rear my cooling problems
      actually got worse.  Maybe the additional "load" on the water pump hindered
      the movement of the solution through the system.  All I know is that the
      movement of the rad didn't work for me.

      Frank,
      Correct, I'm having to find a few rubber elbows and the point on beading
      the tube is a good item as well. I don't intend to bend any aluminum tube
      tho it would be neat if one could radius around the firewall.
      I posted pictures on the subaru page on my site and the journal
      part 5 has been updated so far on process.
      Won't fly until next spring no matter what.
      Keep me posted.
      Thanks,
      Larry

      Many people use 3003 tubing as it is soft and doesn't crack as easily as the
      tempered stuff.

      Is there any way to get the top skin on a 701 wing without some oil canning? I
      got it on my first wing and thought that I didn't spend enough time leveling the
      ribs, but put in the due diligence on the ribs this time and still can't seem
      to find a middle ground before drilling the skin.
      Ribs 2,3, and 4 seem like they are 5mm low in the middle even though they are the
      same height at the spar and rear channel. As soon as I push the skin down the
      skin deforms.
      
      Is this a losing battle, and should I just live with it?

      Cy,
      The only problem with 3003 is it does crush easily and in the effort to
      tighten a clamp down, it does not have enough punch to stay tight as
      a larger diameter pipe.  6061-T6 gives more than copper tube with
      less work hardening but will hold better if it is properly supported.
      I agree, that 3003 is probably much easier for flared fittings of small
      diameter and for bending around tight areas, but for me, a 1" straight
      36" piece, well supported, should be a 5052 or 6000 series aluminum.

      I've got the same problem and when I spoke with Nick at S n F, he suggested
      a false top rib about the middle between the two regular full ribs, said
      false rib to consist of an L piece bent to conform to the shape of the top
      of a standard rib and then rivetede to the spar and the rear channel.  The

      I am not a metal expert but I think you can use some aluminum strips over
      the top of the ribs to shim out the differences.

      What metal is used on the 701 skin  .016 or .025 ?
      I am about to reskin a rebuild project (601HD) with .025
      The HD uses .016 and the new XL uses .025.
      I found the metal ( 6061 T6  .025 ) locally and it was pretty cheap.

      Sal,
      The 701 uses .016 aluminum for wing skins. I don't think the thickness is
      really the problem, more likely the large space between the ribs and the
      slight inconsistency in the ribs (or rib placement).
      I used L braces in the right wing to support the skin in between the ribs
      (from rib to rib at about the six rivet from the spar) with no rivets to the
      skin. The L supports the skin from fully deflecting between the ribs and
      keeps it from popping. After riveting everything together I am not really
      sure how much I needed it though. When you rivet the nose skin down it has a
      lifting effect on the rear portion of the skin due to the angle of the spar
      caps compared to the rear wing.
      I just wondered if there was a magical way to avoid it all together.
      
      Thanks Ken

      Hi Hap,
      
      When we beguin building the 701, was our first time with an aluminum
      plane, we were having second thoughts about the strtucture of the
      plane, everything looked so thin and bended like reynolds wrap :-)  
      
      Once we built here the first piece (the rudder was brought already from
       the factory shop by my brother), a 1/4th of the flapperons, we were
      amased how strong and light the plane was coming though, I admire
      everyday more the design capabilities of Mr. Heintz...  
      
      Well, the only thing we noticed when clecoing the wing skins was the
      BIG space betwen the ribs and the oil canning of the skins... our main
      concern was about what would happen when the plane was going to get
      cleaned with the wetted rag by our club's plane keepers, not the
      integity of the wing.  
      
      We decided to add false ribs made like my Pouchel... with blue foam and
      a very light cover of thin fiberglass (suf board mat) with epoxy (to
      prevent melting, just in case a little of gasoline drips [or fumes] get
      inside the wing when refueling). 
      
      The result was a very light but strong rib and the skins areas solid as
      they where built using .250" cromoly :-) not only 0.025" AL (in fact
      they were a hair lighter than the aluminum ribs, using the diet scale
      to compare weights).
      
      The wings ended better than spected.
