      Dear Listers,
      
      Who is Matt Dralle and what exactly are these Lists?  Well, I've been working in
      the information technology industry for over 20 years primarily in computer
      networking design and implementation.  I've also had a rather extensive background
      in web development and CGI design during this period.  
      
      I started the Matronics Email Lists back in 1990 with about 30 fellow RV builders
      from around the world.  Since that time, I have added 50 other kinds of aircraft
      related Lists to the line up and numerous other List related services such
      as the Archives and Search Engine just to name a few.
      
      For the upmost in flexibility and reliability, I have chosen to run all of my own
      servers here locally.  Other support systems include a 1 Gigabit, fully switched
      network infrastructure, a commercial-grade Netscreen firewall, a Barracuda
      spam filter, a local T1 Internet router, and a commercial business T1 Internet
      connection with static addressing.  
      
      The computer servers found here include two, dual processor Xeon Linux systems
      dedicated to the email and web functions respectfully, and another P4 Linux system
      serving as a remote storage disk farm for the archives, databases, and for
      an on-line, hard drive-based backup system with 3.2 Terabytes of storage.  This
      entire system is protected by multiple commercial-grade uninterrupted power
      supply (UPS) systems that assure the Lists are available even during a local
      power outage!
      
      I recently upgraded all of the computer racking infrastructure including new power
      feeds and dedicated air conditioning for the room that serves as the Computer
      Center for the Matronics Email Lists.  Here's a new composite photo of the
      List Computer Center following this Summer's upgrades!
      
              http://www.matronics.com/MattDralle-ListComputerCenter.jpg
      
      As you can see, I take running these Lists very seriously and I am dedicated to
      providing an always-on, 24x7x365 experience for each and every Lister.
      
      But building and running this system isn't cheap.  As I've stated before, I don't
      support any of these systems with commercial advertising on the Lists.  It
      is supported 100% through List member Contributions!  That means you...  and you...
      and YOU!
      
      To that end, I hold a List Fund Raiser each November and ask that members make
      a small Contribution to support the continued operation and upgrade of this ever-expanding
      system.  Its solely YOUR Contributions that keep it running!
      
      Please make a Contribution today to support these Lists!

      Eddie,
      
         I've gotta ask: why are you dimpling your skins? Are you using solid
      rivets?

            Hi Kevin,
            
            Have a look at the DRDT-2
            
            I bought this dimpling tool to do the skins on my XL kit, it works
            beautifully and there is no guessing about how hard the hammer blow
            needs to be, you just pull the handle to compress the sheet metal
            between the dies. It has an adjustable stop so you can't over do the
            dimpling by exerting too much pressure and this guarantees that you
      get
            nice uniform dimples.

            Regards,

      Could the Fortunate Ones (those flying) share their experiences as to the tire
      pressure in the standard ZAC-supplied tundra tires (with tubes) on the 701 on
      grass runways?
      
      Something in the range of 4 to 6 PSI looks okay in the hangar.

      I imagine this is like "questioning the master", but I do question the
      use of 3/16 inch 6061 T6 COLD bend Al.
      That's pretty thick Al. to cold bend, even with a radius. Seems like
      there is major metal weakness introduced with a cold bend with this
      thickness of metal this thickness.....Any thoughts..(see PDF from link
      for note on cold bend)

      Ed, I probably have ten pounds of A4 & A5 left over from what they sent with 
      the kit. Maybe they just gave me extra figuring I was going to screw up that 
      much. I would not worry about it much as ZAC has always sent me promptly any 
      extra or replacement parts. FWIW, Bill

| Subject:  | Pre-Heating a 601XL | 
      
      --> Zenith-List message posted by: "jim" <jim@pellien.com>
      
      Everybody,
      
      Thanks for all of the suggestions on how to pre-heat the 912 in my 601XL.
      
      I cam up with yet another approach.  I bought an 1800 watt wallpaper remover (essentially
      it is a hair dryer on steroids) and blew its hot air:
      
      1st:  up the 912's exhaust pipe  (seemed to work somewhat)
      2nd:   into the 912's water radiator and up into the cowling (seemed to work much
      better) 
      
      On a 32 degree day it took about 20 minutes to get a deflection on the water and
      oil temp gauges.
      
      This is an inexpensive answer to the problem of pre-heating the 601XL.  I only
      had to add a metal tube to the end of the blower so that I could place the blower
      on the ground.  In the rain I am going to cover over the plastic housing and
      fan area with a zip-lock bag to keep out water.  
      
      I've attached two photographs and will upload them to the website.  Unfortunately
      the close-up that was taken did not work for some reason.

      --> Zenith-List message posted by: "Hinde, Frank George (Corvallis)" <frank.hinde@hp.com>
      
      Not sure if the bolt head won't hit the underside of the weldment under
      the wing?
      
      I think I have seen evidence the wheelpant gets very close to the
      weldment during rough landings.
      
      Tell us what Zac says Larry...Oh and how much you could knock out some
      sets of stepped tubes while you got your lather set up as well...:)
      
      Welding is not a problem for me but I aint got no lathe!!!...Ain't got
      no cracks either but I could simply include them with the plane when I
      sell it early next year if I haven't gotten around to upgrading before
      then.
      Cheers

      Hi guys,
      
      I've been grousing over recent gear failures at the forward
      weld-junction of the 1/8-inch gear-strut plates on the 601HD and HDS
      series and want to increase strut-plate thickness on my 601HDS before
      the cracking problem presents itself.  I also want to get the same
      alignment of the main gear without performing any welding near the
      aircraft.  For these reasons, I plan to cut the .058 wall gear strut
      tubes half an inch above the strut plates to remove the thin 1/8" gear
      plates when the aircraft is apart for painting this next spring.
      
      I made a sample weld-assembly of 3/16-inch gear plate per (6-L-1) and
      2-inch diameter, -inch wall 4130 tubes 2-inches long, that will be
      bench-welded away from the airplane.  The tubes will be turned down to
      1.872 O.D. to half an inch of one end to fit inside the .058-wall strut
      tube. (Note that some were made of .065 wall.)  They will be slid up
      into the cut-off gear struts with wheels and tires bolted in place, then
      allowed to settle on the machined-shoulder as axially aligned on the
      plane. They will be drilled front to back and through-bolted using an
      AN-4 or 5 aircraft bolt and Nylock nut.
      
      A proper fit with a small radius in the shoulder plus a wall thickness
      of 1/8-inch material 1-1/2-inches up inside the strut tube and bolted,
      will provide solid attachment that should not present a problem, even
      for the wheel pants configured to fit per Zenith. I submitted this
      process to Nick and I hope it meets with his approval.
      The best of it is maintaining the length of the gear strut, all new
      welds, and more importantly, no welding anywhere near the plane. Worst
      of it is the extra
      2.75 lbs added weight to get it done.
      
      Anyway, I've placed a link to the drawing that comes up to a printable
      size if you're curious.

      Philip,
      You can "easily" cold bend 6061-T6 if you make a jig for the radius.
      I bent 3/16-inch forks using two sizes of roller with the center clamped 
      in place. 
      If you roll it around a cylinder, there are no major stresses, except
      the one you place on yourself.  See links, I could have made the 
      bend-lever longer.
      In this case, it's recommended you bend along the aluminum draw lines even
      though aluminum doesn't have grain like steel.

      I've got 90 hours on my HDS by now and no problems with the forks.

      As a mostly armchair observer here, (a broken wrist makes me particularly an observer
      and a slow typist at present) I am not sure if this "pre-heat" option has been
      mentioned:
      Around here, you can buy an 800 watt in car heater from Canadian Tire for about
      forty
      Cdn $.  In Whitehorse in the 70s, they used to simply place one inside a blanket
      wrapped cowling of their Cherokees to warm them up for first start for a day of
      flight
      training.  Part of the post shut down procedure was to fasten the fitted blanket
      back
      on so the -30 C "breeze" didn't cool the engine too much between student flights.
      
      The car interior heaters have an auto shut down safety thermostat and I've not
      had any
      issues even when a family member has left gloves and hats piled on it in the backseat
      of the car (it did freak me when I saw it in the morning and said family now checks
      for
      clear operation BEFORE pluggiing in the timer for the night!).

      Frank,
      I don't think the bolt would travel the 4" or more to touch the gear box 
      in any case.
      If Nick approves, I'll turn a set of three 2-inch O.D. tubes stepped for 
      .058 wall or .065 wall struts with .196
      thick plates 3.55 square, not drilled, not welded, for $40.00.  If 
      welded, $50.00. plus postal. The tickler is you finding out
      which wall thickness strut you have.
      But, we'll have to wait to hear from Nick.
      Fly safe,

      No. As per info I read in a recent issue of "Note from Chris" he mentioned
      that one could use a flat nose piece with the Avex rivets to have flush
      rivets.

            Hi Kevin,
            
            Have a look at the DRDT-2
            
            I bought this dimpling tool to do the skins on my XL kit, it works
            beautifully and there is no guessing about how hard the hammer blow
            needs to be, you just pull the handle to compress the sheet metal
            between the dies. It has an adjustable stop so you can't over do the
            dimpling by exerting too much pressure and this guarantees that you
      get
            nice uniform dimples.

      I don't have tubes in mine, but generally run ~10lbs in the mains and a little
      less in the front. I have 140 hours with no problems so far. If I am flying at
      gross weight, I will sometimes put a little more in, but I don't think it is

      Hi Larry,
      
      No I'm not using solid rivets, just the 120 degree rivets supplied by
      Zenith. I just liked the look of the flush finish of the rivets with the
      dimpled skin.
      
      One of the guys I met here in Australia was about 70% complete with his
      Zodiac XL kit and had dimpled all the external skins and the finish was
      just fantastic. This more than anything else has motivated me to do the
      same.
      
      I realise that it's more effort and that at the end of the day the
      reduction in drag will be minimal, it's just one of those personal
      preference things.
      
      Best Regards,
      Eddie

      Thanks for the info. Are you using a .125 size bit or #30? Someone suggested
      using the .125 because of slight stretching with dimpling. Given this any
      thought? (this is going to open the flood gates isn't it)

      Hi Larry,
      
      No I'm not using solid rivets, just the 120 degree rivets supplied by
      Zenith. I just liked the look of the flush finish of the rivets with the
      dimpled skin.
      
      One of the guys I met here in Australia was about 70% complete with his
      Zodiac XL kit and had dimpled all the external skins and the finish was
      just fantastic. This more than anything else has motivated me to do the
      same.
      
      I realise that it's more effort and that at the end of the day the
      reduction in drag will be minimal, it's just one of those personal
      preference things.
      
      Best Regards,
      Eddie

            Hi Kevin,
            
            Have a look at the DRDT-2
            
            I bought this dimpling tool to do the skins on my XL kit, it works
            beautifully and there is no guessing about how hard the hammer
      blow
            needs to be, you just pull the handle to compress the sheet metal
            between the dies. It has an adjustable stop so you can't over do
      the
            dimpling by exerting too much pressure and this guarantees that
      you
      get
            nice uniform dimples.

      Hi Kevin,
      
      I am using the #30 drill bit, I have to admit I didn't think about this
      being an issue because the rivets seem to fill the hole quite well. The
      friend of yours that mentioned this, did he think the slightly larger
      hole resulting from the dimple process was an issue ?
      
      The only problem I had is that you can buy 1/8 120 degree dimple dies
      but not the 5/32 120 degree dies, so I had to get one of my friends to
      make these up.
      
      Best Regards,
      Eddie

      Thanks for the info. Are you using a .125 size bit or #30? Someone
      suggested
      using the .125 because of slight stretching with dimpling. Given this
      any
      thought? (this is going to open the flood gates isn't it)

      Put me down for a $50 welded set Larry...Thats very kind of you!
      
      Now the bolt hole will have to be drilled from the outside and
      presumably a spacer tub ground and fitted to the inside?
      
      As a comparison, RV's secure their gear legs in almost the same fashion
      using a 5/16ths bolt. The only difference is the load is not take
      directly by the bolt as the gear legs splay outwards...Then again RV's
      are much heavier too.
      
      I'm also wondering if it is that hard to do a single weld at this
      location?....Your turned piece will ensure vertical alignment either
      way.
      
      Now how on Earth would I find out the thickness of the tube?..:)

      Frank,
      I don't think the bolt would travel the 4" or more to touch the gear box
      in any case.
      If Nick approves, I'll turn a set of three 2-inch O.D. tubes stepped for
      .058 wall or .065 wall struts with .196
      thick plates 3.55 square, not drilled, not welded, for $40.00.  If
      welded, $50.00. plus postal. The tickler is you finding out which wall
      thickness strut you have.
      But, we'll have to wait to hear from Nick.
      Fly safe,

      Jim,
      IMHO, the most important thing to warm up is the oil in the tank and the oil
      cooler.  You want that warm thinner oil to the bearings and bores fast.
      Your approach will certainly make the engine easier to start, but the wear
      internally will be quite high.
      Cheers

      I have a hand squeezer that I have used a lot helping a friend build an RV7-A.
      It is more versatile than the C-arm tool you cited at AS. The C-arm is better
      for dimpling skins but isn't good to use on a part which is already in place on
      the plane (or part of the plane). We also have a C-arm which we use for dimpling
      skins but I think that on the Zenith planes, a hand squeezer would be more
      useful. You want to find one that you can buy a deep yoke for. It will usually
      come with a 1 1/2" or 2" deep yoke but some applications require more reach
      so get a spare yoke about 6" deep. You'll also need a set of dimple dies for
      every size rivet and screw head you plan to dimple for. A set of flat rivet squeezer
      inserts will allow you to set the few solid rivets you may want to use
      here and there on the plane. Check Wicks and Avery tool catalogs.
      
      Hope that helps,

      Thanks to all on-list & off-list for the comments and advice about what works best
      for 701 tire pressure.
      Nice to confirm that at least one guess was correct.
      
      And for some of the off-listers:  NO! I don't think helium will do much for additional
      gross weight; and, NO! a vacuum won't make it a VSTOL.  Thanks anyway!
      But I may be able to steer you to some screen doors for the 701......nearly
      new, recently removed from a submarine.
      
      Best regards to all,

      Dear Thread Friends, now that we have concluded the best tire pressure for 
      701s, what is the consensus of the group on 601XL tire pressure ?  I started out
      
      at 28 pounds and even down to 22 pounds she wiggles and darts on landings. At 
      8-12 pounds she seems to waddle on taxi.  Whoever has the best correct answer 
      gets a free flight in my XL just for the asking (all you got to do is catch 
      me at the airport). Best regards, Bill of Georgia.

      I am installing the same system with fuel flow option. I would guess that  
      the software installed in the unit to make fuel flow work is part of the  cost.

      I also bought a dimpling set for a pop rivet tool (1/8 rivet) for $17.00, 
      works great! Recently I bought a second set because I lost one, guess what, 
      I found it the other day. I will sell one set at a discount if you want it.

      I picked up my 601XL kit in Jan 04 and completed it in June 05. I had quite
      a bunch of rivets left.  The only "bulk" parts that I ran out of were the
      "L" angles, probably because I did not plan out lenght of cuts, but they
      were inexpensive to procure from Zenith. If you have a big enough brake, you
      can make them (and many other parts with and without a brake*) yourself from
      the spare 6061T6 sheet aluminum pieces you receive in the kit.   * I would
      recommend you get at least an 18 inch brake - Harbor Frieght sells them
      cheap.
      
      Logistic support from Zenith was great. (I did "mess up" a few items - and
      they were also inexpensive, especially when compared to any other military
      or civilian aero part)..

      As I am about to fly the demo 601XL and will probably order the kit soon
      thereafter, what is the consensus of the list on how many extra rivets (and
      what sizes)  I should order with the kit? I figure the need for more rivets
      is inevitable (I've built an ultralight trainer so I believe that extra will
      be needed) and I would rather pay for them up front and not have to wait for
      them later plus pay extra shipping. What do the completed builders think on
      this question?

      Philip,
      You can "easily" cold bend 6061-T6 if you make a jig for the radius.
      I bent 3/16-inch forks using two sizes of roller with the center clamped 
      in place.
      If you roll it around a cylinder, there are no major stresses, except
      the one you place on yourself.  See links, I could have made the
      bend-lever longer.
      In this case, it's recommended you bend along the aluminum draw lines even
      though aluminum doesn't have grain like steel.

      Hello Zed,
         
        I had the same question a few months ago,  Also asked the same.
         
        From ZAC, the advise is this simple:  
        The pressure is very low low to get it correct with a normal tire gage,  so Nic
      told me this simple way to get it correct:  
        The height of the lower rim edge to the floor (flat dirt or cement) will be 75%
      of the height of the upper side of the tire to the upper rim (not compressed
      side of the tire).
           
        In my airplane, with this messure, the side of the main landing gear tires make
      some "ricles"(sp?) , like the ones in the drag race cars :-) ...  well I put
      just a little extra tad of air until the rincles desapear.  We fly from grass
      and dirt strips, not perfect flat.
         
        Is important to have it this low the front wheel, because with the grass bumps,
      the front wheel will jump in the landing and take off rol,  more even in slow
      taxi speed...  well, fast taxi is only about 20 mph!!! with any head wind.
         
        Hope this helps.  (and can be undestood)

      Could the Fortunate Ones (those flying) share their experiences as to the tire
      pressure in the standard ZAC-supplied tundra tires (with tubes) on the 701 on
      grass runways?
      
      Something in the range of 4 to 6 PSI looks okay in the hangar.

      Boy you think the 3/16ths is fun to bend have a look at the tool made to
      do the 3/8ths nose fork !!! Base design is From Larry and then I added
      steroids to the design. Though when it came time to cold bend the 3/8ths
      I should have popped a few steroids as well. Seriously Larry designed a
      great tool as always, this unit will make a perfect wheel fork and is
      dead accurate for producing  doublers.

      I like that!  Much simpler than the tool I made for
      the same purpose.  
      
      I bent 1/4" flat bar easilly with it...no milling or
      machine tool required to build the press though.  The
      die is simply a piece of 2" pipe purchased at Home
      Depot.  The female die is made with MDF and some
      plastic guides (material I had at home).  A 6-ton jack
      was used.

      If I build other forks (I'm thinking about replacing
      my 15X600X6 tires and wheels with 500X5 to reduce drag
      and weight), I'll take Larry's way.

      Philip,
      
      I don't see that as a problem.  He is using over 6 times the material thickness.
      You can normally get away with 3 times without cracks using T6 aluminum.  This
      is looking at it from a Pressbrake perspective.

      On my plans, there is considerable twist built into the ailerons.
      
      Perhaps this allows for the rest of the wing to be straight.

      Paul, I think the twist in the wing is in the different length blocks you cut 
      to go under the ribs.

      I'm looking for a source for a rivet copier - at least that is what I think
      the name is. Its sort of a transfer gauge. It is used to drill a rivet hole
      that is aligned with an existing hole covered by the undrilled sheet metal.
      It is basically two metal strips fastened together at one end. The other end
      has a stud on one strip and a alignment hole on the other strip. What is it
      really called and where can I buy a pair (one for A4 and one of A5)? I've
      seen them on some tool web site but can't recall where.

      Not quite but close. That finds the edge of the flange. The tool I am
      thinking of is built almost the same way but has a stud that drops into an
      existing rivet hole. I'm getting hits in Google when I search for a "strap
      duplicator"
      
      http://www5.mailordercentral.com/clevtool/prodinfo.asp?number=SD12140
      
      Now I just need to find one for a #20 bit and A5 rivets. At least I getting
      somewhere.
      
      Thanks, Craig
