      Piet friends, Susan and I are looking forward to hosting lunch at Brodhead 
      
      Friday, July 25, 11:30 to 12:30. We will be located on the SE edge of the 
      
      field by the white fence. 
      http://www.eaa431.org/wp-content/uploads/2013/07/C37-Fly-In-Diagram.jpg We 
      
      will have a 100 brats, salad, chips and watermelon.  When they are gone, the
      y are gone. 
      Please bring a drink and chair. Look for the 45 foot brown and black Thor 
      
      diesel. Looking forward to it, let's hope for great weather! We will be

      Doing an informal head count, it appears as if Brodhead might be light of
      planes this year.  Sounds like some of the "regulars" (Mikee, Jack,
      Perkins??, aren't able to make it. darn!
      
      
      Sounds like, Greg, Dan, me, hopefully another black and yellow bird?, one or
      two Pavliga's, hopefully Don??? Who am I missing
      
      
      Is Matt flying in?  Randy?

      I owe an apology to Jon Apfelbaum, truly.  We are on a dive trip out of the country
      at the moment and I have dozens of emails to catch up on (wi-fi is spotty
      down here), but I am remiss in not giving Jon the credit for the cover photo
      on the anniversary edition of the magazine.  We knew it would be one of Jon's
      photos on the cover the minute we saw some of the shots that he took in the photo
      shoot of Dan's airplane.
      
      The photo is one in a series that pilot and photographer took, so if the photo
      looks familiar, just pull out your 2012 EAA calendar and you'll see a similar
      photo but the two are different.  Our thanks to Jon for making this special issue
      of the magazine what it is, and definitely something that will be around for
      many years to come.  Perhaps Jon will agree to start working on the cover for
      the 100th anniversary issue-?
      
      There are one or two other of Jon's photos in the magazine, including one of Matt
      Paxton swinging the hand-carved prop on Dan's airplane.
      
      It's raining outside at the moment, but they tell me it doesn't matter if you get
      wet when you're scuba diving ;o)

      William,
      
      I got out my copy of Harry Riblett's GA Airfoils this morning before I went to
      work and it looks like for a cruise lift coefficient of .55 the angle of attack
      for his GA30-612 is around one degree positive.  Looking at the ordinates for
      this airfoil and assuming a wing is constructed with the front spar at 12% of
      the chord and the rear spar at 60% of the chord, as Mr. Pietenpol designed it,
      I calculated the front cabane should be 1/2 inch shorter than the rear cabane
      to achieve this one degree positive angle of attack.  This assumes that the
      builder constructs the wing with the ribs butted into the bottom of the spars.

      Ray,
      
      
      I will be glad to submit the rigging data to the newsletter, and one of the guys
      can also put it here on this list. When Ryan and I did the CG work several years
      ago, it all went directly into the newsletter for everyone to use. This list
      latter played a role in getting new builders to understand the CG info and
      know where to get it in printed form from Doc Mosher. Those articles are longer,
      and were best introduced in a lasting printed format, the rigging info will
      be comparatively brief and easier to share.
      
      
      Just as with the CG stuff, the information is just a contribution to the Piet community,
      for builders of all power plants to use. I spent about $70K at Embry-Riddle
      and our home is literally lined with bookshelves filled with technical
      aviation books going back to the 1920s, all of this was money well spent with
      the goal of learning more about flight. But still, I can say that at least half
      of everything I have learned about planes in 25 years came from experienced
      people who just wanted to share what they new with others, the only price to
      be paid was being willing to listen, consider and learn. 
      
      
      In contrast to all the other social graces I lack, I have always been respectful
      and grateful to anyone who is teaching me anything. Still, looking back, it
      is easy to identify countless times that I failed to fully appreciate the depth
      or impact some information would later have on my understanding. Most of the
      men I would like to go back and thank again, are gone now. I am left with emulating
      their method of sharing what they knew as the only way I can express my
      gratitude. I learned a lot from many good men, I have a large personal debt to
      pay, I expect it to take the rest of my life.

      William,
      
      At lunch time today I ran the Riblett 30-612 airfoil data through a two dimensional
      analysis software that is, from what I understand, more reliable than the
      Eppler code Mr. Riblett used back in the day.  At a Reynolds number appropriate
      for 75 mph cruise speeds and a 60" chord it gives an angle of attack of 1.104
      degrees for a cruise lift coefficient of .55.  The Eppler code and my eyeballing
      the CL off of Mr. Riblett's graph must have been close. When you do the
      calculations, the front cabanes should be .45" shorter than the rear cabanes based
      on these values.

      Hello good Piet-ple,
      
      I had a friend come over yesterday and we planned to remove one of my four wing
      spars - because it was "cupped" from when the original gentleman had built it.
      
      
      So we got out my small no-kerf pull saws and carefully took to sawing out the spar
      at each location where it was attached to the ribs. Then we cut the spar itself
      in lots of pieces to carefully remove the spar itself...... AND THEN I REALIZED
      WE WERE CUTTING OUT ONE OF THE GOOD SPARS...!
      
      Oh well, we then cut out the "cupped" rear spar in the other wing. The only good
      news about all of this is that I plan to rout pockets in the new spars so the
      new rear spars should be a bit lighter....!
      
      Such are the ups and downs of homebuilt airplane "progress" :-)
      
      Jake
      
      Attached is a photo of the second, cupped spar in pieces as we were carefully removing
      it......

      Jake,
      
      Well, I guess it was good experience, in preparation for the spar that counts!
      
      
      I know your pain as I had to replace a spar last year. I was very glad that I did
      not glue my ribs to the spar!

      That's better than building two right or two left wings Jake but none the l

      Jon,
      
      
      I wanted to point out to everyone that the sign up pages and information sheets
      for both Corvair College #30 and #31 can be found at this link:
      
      http://flycorvair.net/2014/06/19/corvair-college-30-and-31-sign-up-now-open/
      
      
      Pietenpol builders should feel more than welcome at #30, even though it is being
      held September 16-19 at the Zenith factory in Mexico MO. Sebastien Heintz, president
      of Zenith is a friend of ours, and he always points out that all homebuilders
      are welcome at any event at his facility, not just Zenith customers.
      I have not looked at the sign up sheet closely (it is taken care of online by
      Ken Pavlou), but the event was 50% full last week, and we usually have a number
      of Piet builders at every college.
      
      -------------------------------------------------------------------
      
      College #31 is November 7-9 at Barnwell SC, with Pietenpol builder and flyer PF
      Beck and crew. Pietenpols are well represented at Barnwell events, and Don Harper's
      plane is based there as well.
      
      ------------------------------------------------
      
      Kevin Purtee and Shelley Tumino, aka "Axle and the IT-girl" , who will be at Brodhead,
      hosted Colleges #28 and #22 in Texas. We had a good turn out of Piet builders
      at both, because the local hosts always tend to draw a lot of builders
      from their own group of aviation friends who are working on the same airframe.

      Jake, thanks! I was moaning about what a bad day I was having. Then I got
      your email.
      
      After sawing through a 1x1 that was part of a mapshelf John Kuhfahl put in
      (to make room for my shins) I suddenly had a heart attack that I had sawn
      through a structural member. I could not find this structural member on the
      plans or in any photos. Then John told me 'No that is not structural! just
      a shelf." So I understand, sort of.

      Doug,
      
      
      That is some very good detective work. I strongly suspected that using the angle
      of incidence in the plans would be over doing it, your notes confirm this. When
      we go through the measurements at Brodhead, there will be more to learn. If
      you also have the ability to run the BHP airfoil through the same simulation,
      I would be very interested in seeing it, and then checking it against anything
      we can field test. 
      
      ----------------------------------------------------------
      
      Does anyone know how many Riblett -airfoiled Piets are flying? I would be very
      interested in hearing from pilots who are, what their cabane lengths are, and
      what their rigging data looks like. We could include all of that information with
      the Brodhead information, and hopefully have hard information builders to
      use in planning their plane or tuning the one they are flying.
      
      -----------------------------------------------------------
      
      When we first started flying my Piet it only did 73 mph flat out. reworked many
      things on the plane in the following year, and raised the top speed to 105 mph.
      The plane was pretty well mannered and normal between 55-90 mph, but from 90
      and up it lost some pitch stability. Flying at high speed puts the wing at a
      very low angle of attack, runs the fuselage nose down, and make the stabilizer
      run at an odd angle to the line of flight. There are limits to every combination,
      but within the a wide speed range it is possible to fine tune the plane
      to fly pretty well.
      
      -------------------------------------------------------------
      
      Many years ago the KR-2 community looked at the same ideas, the designs original
      airfoil was an RAF-48 set at a 3.5 degree incidence, This worked ok with a 1600
      cc VW and modest cruise, but it produced poor stability and odd rigging problems
      when the plane had the potential of cruising 30% faster. Some builders
      switched to a different airfoil, but as a general rule, all the people using more
      powerful engines decreased the angle of incidence in the wing. It is considered
      a great improvement on faster planes.
      
      -------------------------------------------------------------
      
      Took my last flight in my Pietenpol 13 years ago today. I have been trough all
      four stages of Pietenpol-hood, dreaming of one, building one, having one , and
      wishing I still had one. I bought my plans from Don in the spring of 1989, and
      I used to devour every word in the old Piet newsletters, both the ones from
      Ohio (BPN) and the ones from Iowa.(International Piet news). For my first few
      years, everyone I was friends with in homebuilding was a Pietenpol person, and
      I lived under a very pleasant illusion that everyone in homebuilding was probably
      as nice as Pietenpol people. Working in the industry for all these years
      has brought us many friends, but has also revealed that the Pietenpol building
      community are a very rare oasis of salt of the earth people, and for reasons
      I still can't articulately explain 25 years later, I still think of Pietenpols
      as my home in homebuilding.  -ww.

      I can't technically comment on airfoils but didn't P.F. Beck and another gentleman
      at Barnwell make a detailed comparison of the Riblett and other Piet airfoil
      sometime in the last couple of years?

      William,
      
      I ran the polars a few years ago for Mr. Pietenpol's airfoil and have them on my
      computer at work.  I'll print them off tomorrow (if I can find them) and will
      bring them to Oshkosh. I believe one of the Reynolds number I ran was appropriate
      for 75 mph cruise, but will verify this.  If not, I will run them again.
      It should be interesting to compare the real world, empirical data you collect
      at Brodhead versus the theoretical values the software comes up with.
      
      I remember a few years ago reading on this forum of a gentleman named Lowell Frank
      who had a Riblett 30-612 on his Piet.  I also (vaguely) recall he had   either
      equal length cabanes or front cabanes one inch longer than the rear and that
      he had to apply forward stick pressure at cruise and higher speeds.  If I
      am remembering this correctly it makes me suspect my calculations are correct
      in that the front cabanes should be shorter than the rear by 1/2 of an inch in
      order to establish an appropriate angle of incidence for 
      this airfoil on a Piet at cruising speeds.

| Subject:  | Speaking of latex drying | 
      
      I am about to paint the wings. I have them on a cradle with wheels. It holds
      both wings nose  down with two straps across the leading edges.  They lean
      together against a foam "noodle" about 3/4 back on the chord.
      
      
      My plan is to spray paint the top starting about 16 inches back from the
      leading edge. then when "dry" I will rotaten them and do the bottoms. Then
      when dry I will set it on a couple of tables to spray the leading edges.
      
      
      The high quality sherwin williams DTM latex (acrylic) paint  I am using
      says it is dry to the touch in 30 min to an hour. tack free in 2-4 hours,
      and to recoat in 2-4 hours. It cures in 30 days.
      
      
      How long should I wait before I can lean the newly painted surface against
      the noodle? How about putting the leading edge back down into the cradle?
      
      
      Are there any other tips yall have? IE how do I fill the inspection holes
      so I can spray around them?
      
      
      Blue Skies,
