      Hey Dan,
      
      
      Years ago, I delved into this subject when coming up with ways to replicate
      the performance of WWI type engines.
      
      
      While the Ford is much closer in performance to these older engines than
      modern aircraft engines, there are still some major differences which
      account for the Gnome's ability to spin that large paddle prop while the
      Ford struggles with your four-blader.
      
      
      First off, the 50hp Gnome is a 488 cubic inch capacity engine while your
      Ford is around 200...
      
      
      Secondly, it is producing all of it's torque at 1200, while yours needs to
      spin up closer to 2,000 to produce max torque.  Since drag on these props
      increases exponentially, one can see how much more power would be required
      to spin that prop even a few hundred rpm more.
      
      
      With old engines, airplane guys always get confused with HP and torque,
      assuming that a modern 180 Lycoming can spin the same nine foot prop a 180
      mercedes of almost 900 cubic inches did.  IT can't, they are two different
      animals.
      
      
      It's like the old 35hp tractors which can pull three plows behind them while
      your 500hp mustang never could.
      
      
      I think it's a great experiment, but my guess is that you'll need to
      gradually thin those blades down until you can turn up a bit more.
      
      
      Good luck!

      As Piet folks, we really don't spend much time rigging our planes.  Most Piets
      fly around with the elevator not in line with the stab in normal cruise flight.
      
      The Piet tail is not a lifting tail like a bleriot (spelling) or something.  Even
      though the elevator is deflected down in level stable flight, the tail is holding
      the nose up.  What that would indicate is that the stab should be trimmed
      out to eliminate that extra drag.
      
      Struts and washout should be trimmed for fastest cruise.  Incidence should be trimmed
      for minimal drag...
      
      When I rebuilt my Piet, which included making new wing struts, I'm sure the plane
      was rigged differently than before.  However, it felt the same so I let it
      go at that.  However, it was faster than before, I attributed it to finally being
      comfortable enough in the plane, and by myself (before always instructing
      my son) to realize it went faster with the ball 3/4 out to the right, meaning
      the plane wasn't rigged right, the ball indicator wasn't rigged right, or the
      new struts just happened to rig the wing in a way that was faster.
      
      While airfoils obviously make a difference, in our performance zone, I'm thinking
      stuff like I mentioned is simply more likely than the trailing edge difference.
      
      Larry Williams thought maybe his leading edge half ribs slowed his plane down significantly...
      who knows?!

      A tiny piece of pipe tape could clog the tiny fuel passages in the 
      carburetor.  This makes the engine quiet, and we all know noisy planes 
      are the most fun. 
      
      Spruce sells a product called "fuel lube" made for this purpose.  It 
      helps seal the threads, and also acts as an anti seize.  Use sparingly.

      Hey Bob,
      
      
      I remember a similar problem getting my strainer(s) to screw nicely into 
      the aluminum weld-on fitting.  Assuming you have the matching 
      sizes
      
      
      I forced one, NOT the way to go because the brass just rethreads the 
      aluminum making it worthless when you need to remove it.  I bought the 
      correct size national pipe thread tap and lightly cleaned out the 
      aluminum bushing threads.  I also needed to do this because the finger 
      strainer didn=99t want to go far enough in.  It stuck out way too 
      much and was ugly.
      
      
      Also, ck the brass threads for nicks and dings which could be making 
      things harder.  
      
      
      Ck for proper size first though.
      
      
      Remember NOT to use pipe tape.

| Subject:  | ford oil pressure | 
      
      
      Ok... got my engine back together and ran it yesterday.
      I modified the oil pump per a ford Nov1932 service bulletin to increase the oil
      flow and machined the housing and gears to increase pressure a bit per billsbangers.com
      
      To my surprise, after running it I saw a steady 2lbs of pressure.
      I plugged the line going from the pump galley to  the front of the pan...red arrow
      below.... and that gives me 5-6 lbs.. I know the increase in flow is big..
      and its feeding the bearings for sure cause I now have a front main leak.. but
      i'm wondering how important the line, red arrow, from the pump to the dipper
      tray really is... could it be restricted a bit or go away. the other line from
      the valve galley is feeding the tray and all the oil from the mains hits the
      tray too. The line from the pump to the tray is just a big "leak" on the pressure
      feeding the mains.
      about to pull the pan to fix the main seal

      I have a run-of-the-mill air compressor with a regulator/oil separator and an additional

      Is that enough filtration to spray paint with either latex or aircraft dope?

      I suggest a small inline filter just before the gun. They are inexpensive, and
      offer a last chance filter.

      In TX, your biggest enemy is going to be humidity.  
      
      The best way to get rid of that is to run the air through a copper coil in a bucket
      of cold water, then a regular water separator, then a small inline dessicant
      filter right by the gun.  
      
      If you don't have that readily available, even all the air hose you have in a bucket
      of cold water.  The goal is to condense the water vapor to particles, which
      the filter can eliminate.  The little dissicant filter (a small little thing
      with a particulate filter and dessicant, you know when it saturates by a change
      in color).  Most compressors aren't blowing out a lot of oil.  If you use
      hoses that have been used on a system with an oil mister, that's a different
      story.  But the little dessicant filter should get the little that might make
      it through.  I've never noticed any.

      Here's the inline dessicant filter:
      
      http://www.harborfreight.com/inline-desiccant-dryerfilter-68215.html
      
      It's important to use a "pre filter" with the bucket of cold water and water particle
      separator because I've trashed one of these in a flat two minutes without
      it!  
      
      I now use a large dessicant filter, about the size of the water particle separators.
      You can remove the dessicant and dry it out in an oven.  It was about 80
      bucks ten years ago, not sure what they run now.
      
      Here's the regular filter:
      
      http://www.harborfreight.com/12-standard-air-filter-68279.html
      
      If you can cool the air before it enters, you can literally see it fill with water
      as you use your air compressor.  For MAXIMUM effect, route your air directly
      from the compressor pump, through some sort of cooler (on my GMC motorhome's
      air suspension system, this is a 5' length of 1/4 copper line snaked around
      the pump itself, and is cooled by the pump fan), this filter, THEN your tank.
      That will keep the majority of water out of your tank, extending its life significantly.
      
      I don't know why compressors aren't just built this way...

      Dan, I think we are all contemplating this. Did you scallop the aft edge 
      of this plywood or do you have a spanwise ridge on the upper suface of 
      your wing where the fabric transitions from being supported by the 
      plywood to being unsupported?
      
      Does your airplane stall gently or sharply?
      
      I have always been under the impression that the aft edge of LE plywood 
      should be unsupported between the ribs to allow for a smooth airflow 
      transition.

      Greg,
      
      No scallops. Just a straight cut (spanwise ridge). The plywood goes back to
       the aft edge of the spar. I would describe the stalls as gentle. I have no
       idea why my ship would be any faster than others. It has all the draggy st
      uff the others do. The only other thing I can point to might be my aileron 
      piano hinges. These are somewhat unique, in that they are mounted flat on t
      op of the wing (and aileron), upside down, and I actually recessed the wood
       where they are screwed in, so that the top plane of the wing is not upset 
      by the thickness of the hinge or the bump where the wire goes. I can't imag
      ine it can make that much difference.
      
      I had this wing all complete like that before I heard others say to do it t
      he other way. I was kicking myself because it looks better the way most hav
      e done it, and I was admittedly worried about that ridge acting like a spoi
      ler. Its not much but it is there.
      
      Maybe its the 1/16" wire I used to brace the tail (like the Last Original).
       :O)

      My understanding is same as Greg's. Dan, I think your obvious speed
      advantage is coming from those Fancy Dan wheel covers!!
      
      
      Seriously, though, you may have hit upon the best prop pitch/dia/profile.if
      you are happy with its climb. Prop #2 for me was definitely a cruise prop,
      causing me to throttle way back to keep it under 90! At that speed, "I
      didn't like it much!" But it had a very poor climb rate.

      When Larry and I flew over to Brodhead together a couple of years ago I had
       to do S-turns for him to catch up. As I say, I don't know why. He says his
       is the world's slowest Pietenpol, and has tried other cylinder heads and p
      rops trying to get it to go faster, to no avail. Tools, you may be correct 
      that my rigging just happens to be as good as it can be.

      As Piet folks, we really don't spend much time rigging our planes.  Most Pi
      ets 
      fly around with the elevator not in line with the stab in normal cruise fli
      ght.
      
      The Piet tail is not a lifting tail like a bleriot (spelling) or something.
      
      Even though the elevator is deflected down in level stable flight, the tail
       is 
      holding the nose up.  What that would indicate is that the stab should be
      
      trimmed out to eliminate that extra drag.
      
      Struts and washout should be trimmed for fastest cruise.  Incidence should 
      be 
      trimmed for minimal drag...
      
      When I rebuilt my Piet, which included making new wing struts, I'm sure the
      
      plane was rigged differently than before.  However, it felt the same so I l
      et it 
      go at that.  However, it was faster than before, I attributed it to finally
      
      being comfortable enough in the plane, and by myself (before always instruc
      ting 
      my son) to realize it went faster with the ball 3/4 out to the right, meani
      ng 
      the plane wasn't rigged right, the ball indicator wasn't rigged right, or t
      he 
      new struts just happened to rig the wing in a way that was faster.
      
      While airfoils obviously make a difference, in our performance zone, I'm 
      thinking stuff like I mentioned is simply more likely than the trailing edg
      e 
      difference.
      
      Larry Williams thought maybe his leading edge half ribs slowed his plane do
      wn 
      significantly... who knows?!

      Ok... got my engine back together and ran it yesterday.
      I modified the oil pump per a ford Nov1932 service bulletin to increase the
       oil 
      flow and machined the housing and gears to increase pressure a bit per 
      billsbangers.com 
      To my surprise, after running it I saw a steady 2lbs of pressure.
      I plugged the line going from the pump galley to  the front of the pan...re
      d 
      arrow below.... and that gives me 5-6 lbs.. I know the increase in flow is 
      big.. 
      and its feeding the bearings for sure cause I now have a front main leak.. 
      but 
      i'm wondering how important the line, red arrow, from the pump to the dippe
      r 
      tray really is... could it be restricted a bit or go away. the other line f
      rom 
      the valve galley is feeding the tray and all the oil from the mains hits th
      e 
      tray too. The line from the pump to the tray is just a big "leak" on the 
      pressure feeding the mains.

      I'm not sure how to do it, perhaps just really good photography, but a close observation
      of the attitude of the top longeron of the fuse between your two Piets
      while in very stable level flight should reveal the relative condition of the
      rigging.
      
      Maybe just a good level, perhaps an iPhone's app would work, dunno.
      
      But a lot of extra fuselage hanging out in the breeze is HUGE.  When I ferried
      2RN home, after taking off one very smooth morning, I found myself settling back
      down towards the trees!  I was panic stricken as I cycled the carb heat, double
      checked the airspeed, etc.  I finally realized the ball was WAAAAY out to
      one side (remember, this was my 5th Piet flight!  My 8th light civil flight since
      high school...), I centered it and climbed normally (still not good, had
      a very cruisey prop).  I was shocked at how performance limiting that slip was.
      Just a few degrees of yaw or a non level fuse (relative to relative wind) would
      make a very noticeable difference.

      So here's the deal.  I'm ferrying a Dakota Hawk (wood, plans built, tail wheel,
      no transponder, sound familiar?) from outside Milwaukee to Maine.  The route
      from the PA border up to Maine is pretty straight forward but I need some suggestions
      on coping with Chicago and Cleveland air space.  Did I mention NO transponder?
      
      Those of you who fly from mid-Ohio to Brodhead have a preferred route south of
      the ORD Class B and I can't remember what it is.  Also, is there an easy way past
      CLE at intermediate VFR altitudes?
      
      Thanks All

      Dave,
      
      
      You didn't mention whether or not you will have a GPS.  Assuming you do,
      here is the route that I would program in to get you around Chicago:
      
      
      I fly from Brodhead to Poplar Grove, Illinois (C77), then go to Swett
      intersection (which should keep you clear of Aurora's Class D airspace) then
      to Joliet (KJOT)  After you get to Joliet, you should be clear of Chicago.
      
      
      Maybe Mike Cuy can chime in with advice for avoiding CLE airspace.

      So here's the deal.  I'm ferrying a Dakota Hawk (wood, plans built, tail
      wheel, no transponder, sound familiar?) from outside Milwaukee to Maine.
      The route from the PA border up to Maine is pretty straight forward but I
      need some suggestions on coping with Chicago and Cleveland air space.  Did I
      mention NO transponder?
      
      
      Those of you who fly from mid-Ohio to Brodhead have a preferred route south
      of the ORD Class B and I can't remember what it is.  Also, is there an easy
      way past CLE at intermediate VFR altitudes?
      
      
      Thanks All

      To those more knowledgeable on this list:
      
      I suspect that more engines have been used to power the Pietenpol that
      any other plane in history.  This might be a good topic for an article
      for the all-Piet issue of CONTACT magazine.  I am very curious how
      many have been used successfully.
      Here is the list of the ones I can name off the top of my head.
      Please add to the list any others you know of, or redefine any that I
      have misnamed or are incorrect.
      
      Continental  A-65
                        A-75
                        C-85

      Lycoming     65 hp
                        O-235
      
      Ford          Model A
                      Model B
                      Flat head V-8
                      Escort engine
      
      Funk variation of the Model A
      
      Warner radial  (Which one I do not know)
      
      Velie radial
      Rotec radial
      Lambert radial
      
      Buick V-8
      Corvair
      Toyota  (I don't remember which one, but there was a pic a few months ago of
                           two Piets in New Zealand who were powered by Toyotas)
      
      Geo/Suzuki  2300 cc
      
      Mitsubishi  (soon to be)
      
      (Was there a Continental 50 hp, a Volkswagen, a Lycoming 125 hp GPU,
      or a Kinner?)

        Dan, I think we are all contemplating this. 
      
        I have always been under the impression that the aft edge of LE 
      plywood should be unsupported between the ribs to allow for a smooth 
      airflow transition.

      There was also a Vega powered Piet and don't forget Mountain Piet with the 
      turbo Subaru.
      
      There is one being built in Minneapolis in which a Honda V-6 is being 
      planned.

      I completely agree with tools.  Rigging the airplane and the control surfaces,
      as well as setting the engine thrustline properly, has made a very noticeable
      difference in the way Scout flies and handles.  It absolutely, positively has
      to make a difference in drag when all the control surfaces are aligned and the
      engine thrust is being applied most effectively.  Your airplane must be exceptionally
      well squared and true.
      
      Think about the four primary forces acting on the airplane: thrust, drag, lift,
      and gravity.  Among the hundreds of different Piets out there, several of these
      factors are going to be quite close to one another, so it comes down to small
      variations.  Given a Piet with a Ford engine and radiator, landing gear, and
      empty weight similar to yours- how many things can be different?  With the same
      empty weight (or gross weight), gravity is the same.  With the same airfoil
      and span, washout, and dihedral- lift will be the same.  With similar engine
      and prop, thrust will be the same.  And with rigging, landing gear, cowlings,
      windscreens and general finish being similar, drag will be the same.  So now
      you have to start looking at the small nuances.
      
      People have made it their life's work to optimize aircraft performance by small
      but careful detailing.  Roy LoPresti, Klaus Sauvier, Mike Arnold, and others
      have done this.  Apparently you've done it as well, since I doubt that you carry
      a leather pouch of pixie dust that you reach into for a pinch to sprinkle on
      your airplane before each flight.

      Mario: your question is too general.  Are you asking about electrical wiring, mechanical
      connections such as throttle and tachometer, or maybe just about how
      to pass through the firewall?
      
      Do you have an electrical system (battery, alternator, starter, etc.)?  If not,
      that makes it much simpler.
