      Has anyone installed a oil thermastat on the 912 uls on a 701? I am in 
      the process and am having a few issues of finding a location for the 
      thermastat. Would like some experienced advice.

      For anyone wondering about this wing, Raymond is ramping up for production but
      not quit there yet.  So I have posted the link to the web archive of the old Dedalius
      website. I'm not sure if the new wing will be exactly the same or not
      and I don't want to infer that it will or will not be. But when I went looking
      for info on this wing I came up goose eggs, until I found this link...

      There is one advantage for the 912 over the S.  It runs on regular
      auto gas, the S needs premium, so the cost of operation is less.  I am
      building a 601XL with Jabiru 3300 so the whole discussion is academic
      but interesting.

      Nice find on the wayback machine!  I also had come up with zero when
      searching around about this wing.
      
      Anyone here using the PegaStol wing?  Care to give us some performance
      data?  Is each slat independent or are they linked together?
      
      I wonder what the use of flaps and ailerons does to things like roll
      rate and crosswind capability.

| Subject:  | Re: what size screw?? | 
      
      Dred, you did answer my question (it is a #8 screw) - thanks much !
      
      The precise piece of information I was looking for, I found in Wikipedia
      (right under my nose, but I guess my brain was already sleeping when I
      posted my note last night):
      
      "Machine screws are described as 0-80, 2-56, 3-48, 4-40, 5-40, 6-32, 8-32,
      10-32, 10-24, etc. up to size 16. The first number can be translated to a
      diameter, the second is the number of threads per inch. There is a coarse
      thread and a fine thread for each size, the fine thread being preferred in
      thin materials or when its slightly greater strength is desired.
      
      The numbering system follows a roughly logarithmic series where an increase
      in each screw number size approximately doubles the tensile strength of the
      screw and is given by Dia = (#N X .013") + .060" Using this formula a #5
      screw has a major diameter of .125" (1/8"), a #10 screw has a diameter of
      .190" (or 3/16" in practical terms), etc. The formula applies for screw
      thread numbers #0 and higher, but does NOT apply to smaller Unified
      miniature screw thread series. Typically screws smaller than size #0 are
      supplied in the Unified Miniature Series. The formula for number sizes
      smaller than size #0 is given by Dia = .060" - (#zerosize X .013). So a #00
      screw is .047" dia, #000 is .034" dia, etc.
      
      The number series of machine screws once included odd numbers (7, 9, etc.)
      and extended up to #16 or more. Standardization efforts in the late 19th and
      the early part of the 20th century reduced the range of sizes considerably.
      Now, it is less common to see machine screws larger than #14, or odd number
      sizes other than #1, #3 and #5. Even though #14 and #16 screws are still
      available, they are not as common as sizes #0 through #12.
      
      Sizes 1/4" diameter and larger are designated as 1/4"-20, 1/4"-28, etc. the
      first number giving the diameter in inches and the second number being *threads
      per inch*. Most thread sizes are available in UNC or UC (Unified Coarse
      Thread, example 1/4"-20) or UNF or UF (Unified Fine Thread, example
      1/4"-28)."

| Subject:  | Fwd: Fw: nutplates | 
      
      Hello, listers
      
      
      Jeff Small sent me some good information off-list.
      With hist permission, I am forwarding to the list.
      
      Cheers

      ---------- Forwarded message ----------
      
      
       Hi Carlos, FWIW...jeff
      
      
       Many builders seem to gravitate toward rivnuts when it comes to fasteners
      that receive screws or machine screws.  They really should be using
      nutplates as nutplates are far stronger than rivnuts and are far, far less
      likely to "spin" when tightening or loosening.
      
      The main reason for looking askance initially at nutplates is that many
      builders may view them as more difficult to install.  That they are, but as
      with anything in building an a/c it gets far easier.
      
      In my HDS I may have 6 rivnuts but dozens and dozens of nutplates and anchor
      plates - ever hear of anchor plates?
      
      Hopefully this info will get you started, or at least view nutplates with a
      bit less trepidation.
      
      Variety is endless; you can use AC43-13 to look over the selection or look
      at the pictures in the Wicks catalogue.  While there are some specialized
      one, most of the nutplates you use for a 601/701 will be the standard
      straight styles in 6-32 or 8-32.  Often the 'mini' size comes in handy.  I
      used some floating nutplates but mainly because I had ordered some to see
      what they were like and decided not to waste my $ but to put them to use.
      Nutplates are structural fittings and if sized correctly are quite strong.
      If you just want to have something for an access plate fastener you will
      like anchor plates.  Anchor plates use SS sheet metal screws with a 'B'
      point - that's important.  Again, look at the pictures in Wicks or ACS.
      
      You need to attach plates with flush rivets, but this doesn't mean you need
      to get all aluminum rivets and do the RV thing.  Get some flat or
      countersunk head 3/32 pop rivets from  Wicks (they can be cheap).  When you
      rivet you'll use a flat nosepiece in your hand riveter, not the domed/dished
      nosepieces you normally use.  To make it flush you need to do two things
      which at first seem to take a lot of time but will get easier as you go.
      One is to dimple the surface of the .016 or. 025 sheet; second is to take
      the nutplate and using your drill press and about a 1/4 bit, lightly chamfer
      the side of the nutplate that will go against the sheet or surface to which
      you want it attached.  Use pliers to hold and you'll catch on as to how much
      chamfer to remove.  You can sometimes (rarely) find already 'dimpled'
      nutplates but not often.  If you are at the beginning of your building
      experience I would highly recommend buying a micro-stop and a variety of the
      pilot cutters (at least in #40 and #30).  The cutters make countersinking in
      thicker aluminum, .032 and up, a breeze.  Not certain I would use them on
      the steel in the actual nutplate, however.
      
      Application:  drill the center hole for the screw first and make it as close
      to the diameter of the screw as possible.  Put a screw through the sheet and
      into the nutplate.  From underside, mark where the two holes go for rivets.
      I normally drill one on the mark (use a .093 bit) then use a silver cleco in
      that hole and drill the other through the other hole.  Removed cleco and
      screw and rivet plate to sheet.  It's a good idea to open up the center hole
      about another .010 before riveting to allow for easy starting and
      alignment.  That's it.
      
      The dimple tool that you see (looks like two fat washers and a nail) comes
      from Aircraft Tool Supply (part # 5102D 3/32 and also in #5102D1/8).  They
      have them in 3/32 and 1/8.  Get both.  Someday you will want to hang big
      10-32 nutplates on the back of the firewall so you don't have to get inside
      on your head to swap out a gascolator or fuel pump - you will be glad you
      can do it from the front of the firewall.  Same thing goes for other places
      where getting to the back of a bolt/nut would be awkward or impossible.
      
      The first pix shows variety of what I used, the two in the center being most
      useful, the one in the upper right which is greenish in color is an anchor
      plate - you can see difference.
      
      Second shows how to form dimple using your hand riveter.
      
      Third shows dimple. This could be cleaner up further if you have a
      micro-stop and #40 pilot cutter - go slowly as the .016 and .025 with which
      we deal doesn't allow much for error.
      
      And that's about it, simple really and unbelievably functional.  Far
      stronger than rivnuts...and on rivnuts; if you take a very small triangular
      file and file a small notch or two in the hole, the metal will obturate into
      those areas a bit and add a small amount of 'turn resistance' when
      tightening the screw.
      
      regards  jeff

      Hi Guys,
      
      I've seen a post on some forums that using water to test your fuel tanks 
      will ruin the Zenith fuel senders (they didnt say why it would), and now 
      I've seen a builder's website where he used water to test for leaks in 
      his tanks and check the senders.
      
      So, will water damage the senders ?
      
      Thanks in advance,

      Hi John,
      
      As you guessed, you are doing a little comparison of apples to oranges.
      
      The Zenith nose pieces have been reshaped to form a dome top on the 
      rivets supplied in the kit.  This is necessary to build your 
      plane.  You cannot use the Harbor Freight, or any other rivet setter 
      nose piece, until you have ground the hollow shape needed.  You can 
      do this yourself or get someone like ZAC to do it for you.
      
      The other issue is whether the reshaped nose pieces will fit your 
      riveter.  If you buy the ones from ZAC they definitely will not fit 
      the Harbor Freight riveter (well, they might fit one or the other of 
      the Harbor Freight riveters but certainly not both).  The ones you 
      can order from ZAC probably fit the riveter they sell.
      
      It isn't very difficult to grind the shape needed into the nose 
      pieces if you are oriented toward that sort of work.  I have made 
      several of them both from scratch and by grinding the nose pieces 
      that come with various riveters.  The trick is to get the final rivet 
      produced to just fit the application without leaving the edges 
      hanging in the air or having grooves pressed into them.
      
      You can send your nose pieces to ZAC for grinding or perhaps do it 
      yourself.  If you are so inclined, I recommend you get a couple of 
      the lower priced Harbor Freight pneumatic riveters and install an A4 
      sized nose piece in one and A5 size in the other one.  You can get 
      the riveters on sale around $25 each and this will save you from 
      constantly changing the nose pieces.  Also, the list members all seem 
      to agree that the Harbor freight riveter is the best one available.
      
      Good luck,
      
      Paul

      The advantage of the HF nosepieces is that they will fit the HF riveter. I 
      presume that Zenith nosepieces fit the riveter they sell. So, if you have a 
      HF riveter, you'd best use their nosepieces.
      
      However, the nosepieces must be machined to form the flathead rivets into 
      ZAC's required dome shape. You can either send HF nosepieces (or those from 
      any other riveter) to ZAC to be machined for $8/ea (<1 week turnaround), or 
      you can machine them yourselves. If you search the archives, you can 
      probably find some info on doing your own machining. You only need to 
      machine the A4 and A5 nosepieces.

      The Dremel works fine and fast, use a small green round ball (silicon
      carbide) or any other stone that has a point or round end, Put the 
      riviet
      gun head in the lathe chuck and while spinning it, fire off the 
      moto-tool,
      hold it with both hands braced against whatever is nearby, and shape the 
      end
      in a nice conical shape, starting from the hole in the center and 
      working
      outward, keep the cone shallow, you can always go deeper.  No gottem 
      lathe?
      Sure you do, put your fastest turning pistol grip drill motor in your
      workbench vise, usually upside down with pistol grip up, (up is towards 
      the
      sky for you airplane builders!) tighten vise enough to hold drill case, 
      not
      crushing it where the armature will never turn again!  Place the rivet 
      head
      in the drill chuck and lock the trigger back and grind away.  Takes 
      longer
      to describe than to do, finish with emery cloth if your stones grind 
      course.
      Hope this helps.

      I installed the Van nasa inlets and vents in my601HD. that took care of 
      the cooling of me. But I have a problem cooling
      my oil. I purchased the plane last fall and had a problem all
      summer. The oil would sometimes get to 250 and that is not
      good.The oil cooler is located at the bottom of the firewall and is fed 
      air through the nasa vent on the side. I even put
      a scoop to catch more air.Lockwood said the oil cooler is large enouth 
      to do the job.An oil thermostat is installed and 
      they said that would not effect the cooler.Sooo..I need help.
      As a last resort, I could cut a hole in the front of the cowling
      below the water cooler and mount it there. I am open to 
      suggestions...Anyone?

      do not archive
      
      Back in '99 I acquired an Emhart air riveter. Needing to modify the nosepieces
      I called ZAC.
      They told me the exact carbide bur they use.  I ordered it from Grainger, modified
      the nosepieces, etc.
      
      As offspring are prone to do, mine used the bur for some worthwhile (so he said)
      project and doesn't have a clue where he lost it. I do not remember the bur
      number....a call to Roger Dubbert at ZAC may get it.
      Seems that I recall it being  a "round-nose tree-shaped" bur; had a 3 or 4 digit
      part number.  The cost was about $15.
      
      There may be some member of the List with a CNC lathe who could demonstrate his
      abilities by volunteering to modify your nosepieces.  A really advanced CNC setup

      Gig:
      
      I buy such pop rivets from Spencer Aircraft in Puyallup, WA.  Call them at
      800-424-1160 and tell them what you need.  You should be able to specify the
      grip length you require.  I can't make out the part no. from the information
      in the catalog but they will know if you tell them the intended use (I buy
      them off the shelf, in person).
      
      Ask them for a catalog when you order.  It has a lot of useful data.  They
      will accept credit cards and mail the rivets promptly.  Spencer has been THE
      place for homebuilders in the Seattle/ Puget Sound area for about the last
      40 years and they are good people to do business with.

      All from page 99:
      
      AD32ABS dome head - cheap
      
      Cherry CCR264SS3-2 and others in the series -  countersunk
      
      Cherry N  CCP-32 and others in series - waaaay too expen$ive
      
      Avery Tools has them also and are fine folks with which to do business.
      
      You don't need a countersunk pop rivet.  What you do need is a riveter 
      nose piece that is flat, not ground out.  Even the domed heads will set 
      almost flat.  I got most of my 3/32 rivets in the little packages you 
      find in the local auto supply superstore.  
      
      Don't have a flat nosepiece???take a .125 piece of aluminum, drill a 
      hole that is a loose fit for the mandrel, slip it over the mandrel and 
      pull away.

        I installed the Van nasa inlets and vents in my601HD. that took care 
      of the cooling of me. But I have a problem cooling
        my oil. I purchased the plane last fall and had a problem all
        summer. The oil would sometimes get to 250 and that is not
        good.The oil cooler is located at the bottom of the firewall and is 
      fed air through the nasa vent on the side. I even put
        a scoop to catch more air.Lockwood said the oil cooler is large enouth 
      to do the job.An oil thermostat is installed and 
        they said that would not effect the cooler.Sooo..I need help.
        As a last resort, I could cut a hole in the front of the cowling
        below the water cooler and mount it there. I am open to 
      suggestions...Anyone?
      
        thanks..paul baker   601hd 210 hrs.on 912
      
        +++++++++++++++++++++
      
        Is the outlet opening equal to or greater than the total inlet area?
        If not the air could be stagnating inside the cowling.

      Hi,
      
      Could you send some pictures of the installation? It would help
      with the analysis.
      
      As for now:
      
      2. I would get rid of the oil thermostat. In my plane, there has never been
      a problem with oil getting not warm enough (190 deg F+).
      
      3. The added scoop may actually interfere with the NACA inlet. See my
      webpage
      
      http://www.utdallas.edu/~klaus/Airplane/cowl_inlets.html
      
      for a scoop that I installed to REDUCE cooling for slow flight,
      but still get good cooling during high-power flight.
      
      4. NACA inlets work only well when the airflow is essentially
      in line with the horizontal axis of the inlet. This means that during
      climb in hot weather, the angle of attack cannot be high. For
      my plane, this means no climbing below 70 kts unless
      the air is quite cold, say 60 deg or below.
      
      5. Finally, can the air get out of the cowl? Look at the bottom
      lip on the same picture showing the modified NACA inlet,
      on the above web page. One way to test for this is by a
      water gauge that measures pressure differential across
      the oil cooler.
      
      Hope this helps. Please write if you have questions.
      
      Best wishes, happy flying,
      
      Klaus

      In my opinion this kind of advice in general can be disasterous to 
      aircraft.  Well maybe not every time, but Zenith requires a certain 
      radius to properly seat the rivets to conform to the testing they have 
      done on the aircraft.  Grinding to "just any conical shape" migh NOT be 
      so good.  I bought mine from ZAC.  If for no other reason the price is 
      fair and done by American Craftsman.  bob U.

        The Dremel works fine and fast, use a small green round ball (silicon
        carbide) or any other stone that has a point or round end, Put the 
      riviet
        gun head in the lathe chuck and while spinning it, fire off the 
      moto-tool,
        hold it with both hands braced against whatever is nearby, and shape 
      the end
        in a nice conical shape, starting from the hole in the center and 
      working
        outward, keep the cone shallow, you can always go deeper.  No gottem 
      lathe?
        Sure you do, put your fastest turning pistol grip drill motor in your
        workbench vise, usually upside down with pistol grip up, (up is 
      towards the
        sky for you airplane builders!) tighten vise enough to hold drill 
      case, not
        crushing it where the armature will never turn again!  Place the rivet 
      head
        in the drill chuck and lock the trigger back and grind away.  Takes 
      longer
        to describe than to do, finish with emery cloth if your stones grind

          The advantage of the HF nosepieces is that they will fit the HF 
      riveter. I presume that Zenith nosepieces fit the riveter they sell. So, 
      if you have a HF riveter, you'd best use their nosepieces. 
      
          However, the nosepieces must be machined to form the flathead rivets 
      into ZAC's required dome shape. You can either send HF nosepieces (or 
      those from any other riveter) to ZAC to be machined for $8/ea (<1 week 
      turnaround), or you can machine them yourselves. If you search the 
      archives, you can probably find some info on doing your own machining. 
      You only need to machine the A4 and A5 nosepieces.

      Yes, rivets this size are hard to find.  Aircraft Spruce carries flush
      Cherry Q rivets in the 3/32 inch size, but only in stainless Steel.
      Expensive at $.22 each.  Part number CCC-32.

      >From personal experience... I used water to leak test the tank and test the 
      fuel senders.. the problem: you will get erroneous readings on your ohm

      determine the sender resistance at empty and full levels.  I have no 
      knowledge of potential damage to the unit.
      
      Also, do not forget another important test - put your fuel cap on while

      (or those from any other riveter) to ZAC to be machined for $8/ea (<1 
      week turnaround), or you can machine them yourselves. If you search the 
      archives, you can probably find some info on doing your own machining. 
      You only need to machine the A4 and A5 nosepieces.

      You just cant beat good old Dad.  I met my Dad in Branson (the tackiest city in
      the world) over the weekend so we could hang out.  It was my birthday and he
      had a set of flanging dyes made for me buy a local machinist.  What a cool dad!
      
      The other cool thing is that the machinist had a  scale Cub hanging from the roof
      of his shop that he built a long time ago.  Small world.
      
      Check out the picture.

      My Pegastol,  Suzuki powered CH701 is finally done. I am waiting my flight authorization
      to arrive (after a bit of a mixup). It will be faxed to me in a couple
      of days. I expect to be airborne by Saturday, weather permitting. I will post
      some real numbers as soon as I get them.
