Re: Corrosion Treating the Inside of the Cabanes and Diagonals

Terry, The recommended way to address internal corrosion of the tubing is to make sure the ends are sealed, after which small holes will be drilled. Near boiling hot Linseed oil is then pumped into the chamber within, and is "sloshed" throughout. The holes are subsequently plugged with sma...

Re: Pietenpol vertical wing strut support.

Without seeing a picture, you've described what sounds like Jury Struts. These are rather small diameter tubes - or maybe oval tubes - which prevent both buckling and vibration of the main lift struts. While Jury Struts aren't mandatory, they're highly recommended, and should probably be added to yo...

Re: Pietenpol flying club

Steve,

The article was appeared in the August 2016 edition of Sport Aviation, and it was about the Toledo, OH Buzzards.

I think you can look it up online...

Re: nifty nicopress trick

Interesting that you should bring this up, Oscar! I've recently made drawings of an Acme thread clamp system - derived from a 1930's tool - to hold the cable, sleeve and thimble in a vise whilst crimping... My intention is to either provide drawings, or completed tools for sale to the homebuilt airc...

Re: Riblet's Airfoil Design layout

While P.F. Beck's & Don Harpers planes are VERY similar, they are NOT identical. The reality is that Don's fuselage has roughly 10% greater flat plate drag than P.F.'s which, as I mentioned a few years back, is HUGE. ( If this isn't believable, go back and review the fuselage dimensions; then ca...

Re: Riblet's Airfoil Design layout

Airfoils are graphically described in percentages of Mean Aerodynamic Chord, or simply Chord. With such a description, the stations ( X-axis) range from zero - generally the nose of the airfoil - to 100 - the trailing edge. The ordinates (Y-axis), are also in percentage of chord. Some airfoils have ...

Re: Pietenpol Future Hopeful

Luis, Welcome to a very neat and eclectic group of folks, all involved with the Pietenpol! There are a number of items that I can address, but for some, you'll need an experienced CFI (Jack Phillips, please chime in) who also flies a Piet. Answers per your item numbers: 1) I can't answer as I have l...

Re: Insrument Panel

Mike, If you're coming to Brodhead, you'll be able to attend the hour and a half SolidWorks session, where we'll be showing how an Instrument Panel for a Piet may be modeled up. At that time, anyone who wants some of the files I've generated may have them for the asking ( and maybe a cold drink....)

Re: Early Aviation & Engine Books

Steve, Terry, et al, Since these were printed in the late 30's, early '40's, they've been public domain for roughly 50 years now. As Steve mentioned, they're a treasure trove of information for the homebuilder, and are my ready reference when thinking through various construction techniques for the ...

Early Aviation & Engine Books

To All, I've been in contact with my local print shop regarding the books shown below, and they are working up a quotation to duplicate them. At this point in time, I have no idea what the cost might be, but whatever it turns out to be will be dependent upon the number of you who are interested, as ...

Re: Wanted: VW "Bug" Engine

Kyle, How soon do you need the engine? I have a 1600 dual port engine in need of a rebuild, and it's the one you want as it is has Fuel Injected cylinder heads. In case you don't know, the FI engine had the 8mm ex valve stems, to prevent breakage when extreme temps occurred. When considering an engi...
