      Tom,
      
      I ended up, after trying a number of different types, with the Stewart Warner analog
      tach that WW recommends
      
      Stewart Warner part no: 82636 
      & Stewart Warner sender 82646
      
      I scuffed the chrome bezel with scotch-brite and painted it mat black.
      I then mounted it from the rear in to the panel secured with a home made nut plate.
      
      The automotive gauge is 3 3/8 diameter, much large than the 3 1/8 Aviation gauges.
      But by using the recessed rim and mounting it from the back the difference is less
      than 1/8" and hardly noticeable.

      Listers:
      
      I am getting very close to having a panel to start designing my instrument layout.
      Consequently I need to find the sizes and spacing requirements for the final
      layout.  I am having a little trouble trying to figure out where to find a
      tachometer that looks right for a Pietenpol but still operates electrically.
      I remember seeing one on DJ's website that has a max RPM of 3500 and receives
      it's signals from a tooth counter on the flywheel.  (I'm also planning to use
      a Corvair engine.)  The ones William Wynne recommends are digital which I suspect
      would get me laughed off the list.  Any recommendations would be greatly
      appreciated.

      I am using a Westach tach which runs off a lead to the mag.  Larry 
      Williams has been using one for a long time with no problems, and mine 
      has worked well on the test stand. 
      
      There theoretically is the potential of a short causing problems in the 
      mag.  Tony Bingilis recommends installing a small fuse between the mag 
      and tach just in case.  This is what Larry did, and I will do once it's 
      in the plane.
      
      You can find them in the ACS catalog.

      That same tach has a small wire inside that if you have the wrong rpm
      and you cut that wire it will give you the proper rpm.I believe it cuts
      the rpm in half when you cut the wire.It does come with a fuse.I haave
      the same one.I use it in my N3 Pup.My Piet uses another type of
      tach.Can't remember at this time what type that is.

      Sorry to answer your question with another question but have you read the
      archive threads and BPA newsletter article concerning the Riblett 612
      airfoil for the Pietenpol? If I was were you are in the building process I
      would order the excellent full size 612 airfoil plans from Roman ($10) or
      get the coordinates from Bill Rewey for a couple bucks. Just an interesting
      alternative.

      I don't know about the 612, but I will be bringing along a NACA 4412 rib jig 
      and I have a overlay for the regular Piet rib.  The 4412 is used on the 
      Champ and also has been used on the Piet.  It, like the 612 has better stall 
      habits and is a bit faster thean the Piet airfoil.  I will have cap strips 
      there and if you want, you can build a rib or 2.

      Looking ahead a few months...
      
      As I just read in the most recent BPA newsletter, at this year's
      Pietenpol Reunion  (July 20, 21, 22) the BPA News is planning to sponsor
      forums all day on Saturday.  The last couple of years have not had much
      in the way of forums - but this year looks like there should be a good
      selection. Here's a link to the newsletter website:

                        Ultraviolet Absorption of Latex Paints by Kirk Huizenga     
                 For many years there has been discussions on the Pietenpol mail list
      as to the suitability of exterior latex paint as a system for covering an aircraft.
      A number of builders have completed their projects and have used latex
      paint to cover the fabric with claimed success. 
        One issue that had not been tested is the ability of latex paint to protect Dacron
      fabric from damaging UV light. In standard systems, there is a barrier layer
      of paint applied prior to color coats. 
        In the Poly-fiber system this is called Poly-spray. In the past, builders that
      have used latex paint to cover their fabric have sealed the fabric with black
      latex paint with the idea that black paint would absorb the most visible light
      and, hopefully, UV light. This, in turn, would protect the fabric from degradation.
      
      
            I have considered using latex paint on my Pietenpol rebuild, but wanted to
      be certain that it would, in-fact protect the fabric from UV degradation. There
      are builder that have had latex covered fabric for over 10 years without incident,
      but better safe than sorry. One should not assume that because visible
      light is being blocked that UV light is also being blocked. 
        Methodology: I contacted a friend of mine, Dr. Tom Varberg, a Professor of Chemistry
      at Macalester College in St Paul, MN and asked him about testing the paints.
      Tom agreed to help me in the testing by using a Beckman DU7400 Spectrometer.
      The spectrometer can record Transmittance, the amount of visible and ultraviolet
      light lost (or conversely, absorbed) by a material. Transmittance is
      the ratio of radiant power (p/o ) that makes it through the substance (paint)
      to the radiant power (P ) sent into the substance. 
        Transmittance can then be converted to Absorption (A) with the formula. Tom also
      supplied me with a small disk of quartz to use as a base for testing the paint
      at an appropriate thickness - similar to that expected when covering fabric.
      Quartz does not absorb or restrict UV light in the wavelengths we were PO
      P T = PO P A = −logT Ultraviolet Absorption of Latex Paints by Kirk Huizengatesting
      (400-200nm) and therefore would not introduce error in the absorption
      readings. 
        I applied 4 different paints 
      1. Kilz Latex White 
      2. Glidden Exterior Latex-Wooland Green 
      3. Behr Exterior Flat  Black 
      4. Poly-Fiber Poly-Brush) to the quartz with a small brush. 
      
      After shooting a blank to calibrate the spectrometer, one of the painted areas
      on the disk was placed between the light source and the sensor. The light source
      flashes on (2 seconds for our test) and the sensor picks-up any energy that
      makes it through the paint. 
      
      The DU7400 gives a graphic representation of Absorbance at each wavelength (in
      nanometers). In the charts below, I averaged the Absorption of every block of
      10 nanometer since there were 600 data points for each sample (from 800 to 200
      nanometers). 
      
      As a curiosity, I also prepared some lightweight Poly- Fiber fabric generously
      given to me by Gil Leiter of St Paul, MN and tested it. I heat shrunk the fabric
      and tested it with and without paint and Poly-Brush (generously given by Pietenpoler,
      Robert Haines). 
      
      The results are shown in Chart #2. Limitations: The Beckman DU7400 Spectrometer
      is limited to an absorption of 4.5 (but we will consider that to be sufficient
      at T=.0031%) The DU7400 is likely to show erroneous data or noise when at either
      extreme of its measurement (0 or 4.5). Some data for specific wavelengths
      may not be accurate, but a trend is obvious 
      
      The testing we did does not account for reflection. Any light reflected by the
      paint would show up as being absorbed. This doesnt really change the applicability
      of the test results, but does raise a question of what color paint is the
      best to use on sealing and protecting the fabric. This is only a test of the
      UV blocking ability of latex (Continued on page 6) F or many years there has been
      discussions on the Pietenpol mail list as to the suitability of exterior latex
      paint as a system for covering an aircraft.

      expected when covering fabric. Quartz does not absorb or restrict UV light in
      the wavelengths we were Ultraviolet paints. 
      
      It does not deal with any other issues of using non-certified methods of covering
      and painting ones experimental aircraft like longevity, ability to seal the
      weave, adhesion, or flexibility/brittleness of latex paint. The Poly-Spray was
      tested with two layers  one on the front of the disk and one on the back. We
      found that this introduced some errors. Some of the energy that makes it through
      the first layer of paint gets bounced around between the two layers and gives
      odd readings. 
      
      Conclusions Latex paint can sufficiently blocks UV radiation and therefore protect
      Dacron fabric. Color does not seem to matter as far as level of absorption
      differences are extremely minor (in the range of thousands of a percent) 
      
      This is a matter open for discussion, but the practice of using black paint as
      the base/sealing coat on fabric to block UV light may not be the best practice.
      
      
      White, in theory, would be a better paint for that. White paint has a high amount
      of Titanium Dioxide, which is highly reflective. 
      
      Black paint, on the other hand, gets its color from Carbon Black primarily. Black
      paints have much less reflectivity and more absorption of light. 
      
      Now, as I mentioned above, color does not seem to matter much in terms of protecting
      the fabric, but paint that is more reflective should last longer than paint
      that is more absorbing of light. 
      
      It is not an issue of black or white being better at protecting the fabric, but
      rather the longevity and protection of the paint itself from breakdown. Brand
      of paint shouldnt make much difference in terms of UV protection, but could make
      a difference in durability and longevity of your paint job.

      I will be working in the Wood Workshop.  It is up near the main entry.  For 
      anyne else who wants to stop by and help out we will be assemblying a Volmer 
      VJ 22 fuselage this year. If anyone wants some fast progress on a Piet 
      project next near, let us know.  We can fit in another project for the 
      future.  The wood workshop is kind of Pietenpol central at the show.

      One other thing about the 612 drawing, it assumes 3/4" wide spars as most
      people use now days. Using the original plans I, like many people, built the
      ribs with 1" gaps and then added 1/8" ply spacers on both sides when
      assembling.
