      I used pulleys.  Sawing through the cross-member with a cable just didn't
      seem like a good way to go.
      
      
      You can see the elevator cable pulley in the foreground of the picture
      below.  You can also see the pulleys I used for the rudder cables as well as
      the trim system:
      
      
      There's a rule of thumb in the Bingelis books about any change in direction
      of a cable more than X degrees should use a pulley, but my books are packed
      away at the moment and I don't remember what the angle is.  Look it up in
      your Bingelis books.

      Thinking the same thing Gary... But I am trying to convince myself that I
      don't need to spend 35 more bucks for a plane that will only cost me 8000 to
      build... Doap!

      Corky, I am sorry to hear of Isabelle's current condition but delighted
      that you are still raring to go and wanting to build Pietenpols.
      
      For the Piet community, I am also a positive reference.  I bought Corky's
      second Piet project.  I have not finished the project, as my wife and I are
      both battling health problems.  Building will likely not continue unless
      conditions materially change.
      
      However I can attest to Corky's workmanship and especially to the quality
      of his ribs.  He used T-88, individualized gussets and little brass nails
      to hold the gussets.  Lots of detail there, and not a single glitch.
      
      Moreover a buyer may well have opportunities to interact with Corky, a
      treat in itself, as he is an experienced and colorful southern officer and
      gentleman.
      
      Regards to Corky and the board,

      Hey Mark,
      
      
      Great progress!!
      
      
      Technically, according to uncle Tony (Bingilis) the elevator cables deflect
      enough to require a pulley there.  I've never heard of a problem with the
      original layout though; neither sawing through the wood or wear on the
      cables, but.. That being said.. I put two small pulleys back there, and
      would guess that most guys are doing that these days.  Seems a simple and
      beneficial mod, which I can see no reason not to do.

      Well, dang.
      
      Almost done with all the work my current money has left. (Daughter getting
      married in 7 weeks, or 49 days but who's counting...). But, I have the main
      control system in place and all the varnish painting supply's ready.
      
      Thought I'd post a few pictures tonight. Rudder pedals, control tubes,
      rudder bar, control stick assembly with removable front stick (so I can pack
      an overnight tent/sleeping bag in front for fly-ins), and elevator pivot
      tube/horn assembly in place. All I need to do now is cable up the stick and
      see if there is any slack in my set up as some have reported. Anyway, very
      excited to see progress.
      
      If you have not yet started, or are just beginning, have hope! Even if it
      takes 10 years, progress can be made slowly and steady. I have had to wait
      for 6+ months to make any meaningful progress, but tonight I have seen
      almost the completion of the steel parts of the front controls.
      
      Welding was NOT as scary as I thought. Heck, I find I am loving it, and I
      was very fearful of the process (as a search of previous posts would prove).
      I am almost ready to plan the next plane as a steel Pober Jr. Ace, as I have
      those plans already! Actually, I have found that I am pretty good at gas
      welding. This is the real benefit of home building. New skills and
      discoveries. Plus, I can't believe how relaxing the whole thing is. 
      
      My lovely and patient wife approves of the time I am building because she
      knows that while I am out in the barn, I completely STOP thinking about the
      stresses of life. It is, indeed, cheaper than therapy and when you are done,
      you have something to fly!! And Spruse and steel doesn't ask stupid
      questions about your childhood...  :D 
      
      Here's some pictures of the set up...

      Mark, my fuse is not handy for a pic.  I drilled two holes in the cross 
      piece and added two small pulleys on the back of the seat.  I still get a 
      bit of dragging noise when I move the stick, but it seems to be free enough.

      I understand your point, Jim.  You built yours with a door.  This gentleman is
      talking about retrofitting an existing fuselage.  He's going to have to enjoy
      flying light passengers unless he wants to essentially build a new fuselage.

      Mark - I did it per the plans originally.  On the rebuild I'll add pulleys because
      it seems like the right thing to do.  Having said that, the per-the-plans
      treatment was a non-issue.  I added guides that kept the cable from sawing through
      the structure.  The cables wore the guides to a certain point and then apparently
      reached equilibrium - no more wear and never an impact on the structure.
      The cables held up fine as well.
      
      The pulleys are like the piano hinge aileron hinges.  It darn sure looks like a
      better design, even though the per-the-plans design worked fine.  (I noticed
      when I bought strap hinges this time that the quality of the hinges were significantly
      less then what I bought 15 years ago.  I bought the piano hinges and
      will go that route.)

      I also bought a set of ribs from Charlie Rubeck in the late 1980s.  I 
      did it to =9Cblackmail=9D myself into starting on the 
      project.  I figured if I had the $200 (at that time) tied up in ribs I

      the way home to South Dakota.  It worked although I haven=99t

      note indicating he used western cedar (he told me he bought barn siding

      believed him, I didn=99t  count them) and 3000 staples (which he 
      removed).  The extra rib is a fine wall hanging and I used it for the

       I enjoyed many helpful conversations with Charlie in the following

      Did you include any plywood in the laminations? I just laid up the cabanes w
      ith a center layer of mahogany, two layers of 1/8" plywood then a layer if V
      G Doug Fir on the outside. Final Outside measurements are 11/8" by 2".  Of c
      ourse, that will be worked down in shaping.
      
      What grain orientation do you look for with hickory, any?  What about main s
      truts?
      
      Thanks,

      Ray,
      
      
      No plywood laminations on mine. I seriously doubt if plywood adds any 
      strength.maybe some character. 
      
      
      The attached picture is of my current lift struts. You can see the 
      orientation. Also, a strength chart, that shows tensile strength, which 
      is really what you need. Following is my favorite excerpt from an email 
      I got from the very wise Clif Dawson, nearly 4 years ago:
      
      
      "Spruce has a tensile strength of 6700 lb/square inch.
      For the sake of argument let=99s say a strut is 1" X 3 1/2". With 
      streamlining the area should be 2/3 of the square area, or 2.3 square 
      inch. There are four struts or 5.2 square inches. That=99s 34840 
      lbs( yes I know the front ones take the majority of the load) .Dividing 
      on the assumption of equal load on a 1200 lb AC we get 29 g! How much 
      less if properly calculated? 25 g? 20 g? Is this adequate?
      
      There's a bolt at each end. The strength here is based on how much force 
      required to pull a plug of wood out by the bolt. That plug has two 
      faces, the square area of which is the width of the strut times the 
      distance from the end to the bolt. If the strut is 1" thick and the bolt 
      is 1" from the end then you have two faces each 1" square or two square 
      inches. The "shear parallel to the grain" is 1120 lb per square inch. So 
      we have a strength here of 2240 lb. Four struts so that=99s a 
      total of 8960 lb. That's still over 7 g. If we added another such bolt 
      we have 14 g capacity. Taking into account the higher front strut stress 
      I'd bet we  still have at least 10 g to play with.
      
      And this is for plain, solid spruce, no plywood, no laminated straps or 
      embedded tubing or anything else to complicate matters. 
      
      You can add a little more strength by using Western Hemlock or Doug Fir 
      but not much. "

      Yep, sometimes it's good to trust your gut, and mine was saying "pulleys", but
      I was hoping to be able to keep working without having to wait to order them.
      
      But, I'll be flying this for years and pulleys will be better.
      
      Jack, I'd like to see more of your elevator trim set up. I haven't yet figured
      out how to do mine, and your crank assembly in the picture looks good. Do you
      have other pics handy without too much digging around? I hope the construction
      of your place in VA is going nicely!
      
      And Kevin: thanks for the heads up on the aileron hinges. I am planning to use
      the piano hinges too.

      Mark, I compromised on this.  I followed the plans for the low deflection
      cable that runs to the bottom of the elevator control horn, but installed a
      pulley for the high deflection cable that runs to the top of the elevator
      control horn.  It hasn't flown yet, but seems to operate freely when I test
      it in my hangar.  Cheers, Ken

      I mentioned to someone yesterday that I was buying a Piet and about the door idea.
      He said that some Piet's were made with a hatch in the leading edge to enable
      people to get in easier.   I've never seen a pic of such a hatch.  Is there
      any truth to his tale?

| Subject:  | Do I need to sheet this with plywood? | 
      
      
      Hey Guys:
      
      Do I need to sheet this with plywood? I used balsa blocks to fill the space between
      the top.deck stringers as bracing. It goes back about 4" back from the  
      face of the front of the top former/sear back. I was planning to cover this with
      1/8 ply, but after looking at the final product, I am thinking it is plenty
      strong, but I am not sure how much abuse this part gets when sitting on it/ getting
      in and out/ etc.
      
      Will the final covering be enough if I cover the top with some leather like Mike
      Cuy? Just looking for some "been there, done that" advice. 
      
      I do plan to "dimple" or feather the edges to prevent the covering from having
      a hard edge regardless...
      
      Thanks!

      Gary,
      
      Thanks so much!  That really helps a lot.  I printed this out as a permanent
       reference. Beautiful work!

       know the front ones take the majority of the load) .Dividing on the assumpt
      ion of equal load on a 1200 lb AC we get 29 g! How much less if properly cal

      nd to the bolt. If the strut is 1" thick and the bolt is 1" from the end the
      n you have two faces each 1" square or two square inches. The "shear paralle
      l to the grain" is 1120 lb per square inch. So we have a strength here of 22
      40 lb. Four struts so that=99s a total of 8960 lb. That's still over 7
       g. If we added another such bolt we have 14 g capacity. Taking into account
       the higher front strut stress I'd bet we  still have at least 10 g to play w
      ith.

      HI Kevin, 
      
      Actually I had my fuselage all built when Arlene and I got married. Arlene 
      is the bionic women with 3 back surgeries so I wanted to be able to take he
      r flying with me. I added a door after the fuselage was done; took at littl
      e work but ot her than having to rebuild the rear seat framing wasn't reall
      y that hard. Hope to have my Piet done for next years Brodhead to show you.
      
      
      Glad to see all the good progress you are making Kevin. 
      
      Cheers,

      Use plywood. 1/16 is fine. Ties it all together (where did I hear this?)

      I awoke in a cold sweat last night, suddenly realizing that Dan Helsper was
      going to learn that my Piet came out of the factory with a fiberglass
      bump.he would then produce a document from the Secret Files, questioning the
      authenticity of my plane. This bump is necessary to hide a portion of my
      Corvair (A la Last Original) starter (see top of cowling). All I had on hand
      was some 6061 and some homemade tools.and about 3 hours.

      The balsa blocking is probably strong enough, although it might dent easily.
      I covered this area with 1/16" birch plywood, per the picture below:

      I was hoping that those who have built the anti rotation system ala Mike Cuy could
      advise on the Vertical tube dia. and wall thickness and also the dia. of the
      receiver tube and is it a close tolerance. Also the length of the tubes. I
      would like to purchase a new tolerance and related tubing's for my new gear. 
      Thanks Guys for any advise. I am attaching a photo of my old gear just because
      I have it avail on my computer.
