Brodhead Pietenpol Association

Guys, Oscar has outlined some very good info in his posts, and I'm adding just a few additional notes. As stated, the Stromberg carb is typically wired in the full rich position, and according to a few old timers, that’s because the Aircraft Sales guys never thought anyone would fly above 5000 ft, a...

Ture Kane, Since we haven't seen any posts from you, it would be nice to have you follow up with some news about who you are, where you are, etc., so guy nearby your location can invite you to take a look at their Piets... After reading your post, and researching the Verner 5si, it appears that you ...

Bill, et al, Sorry it has taken so long to put this together, as I've been on two trips and gone thru a total hip replacement since the last time I was able to post... In response to your comments regarding the bend radius shown on the prints I uploaded previously, please note that these were hastil...

Arthur, You're right; waterjetting is one of the most expensive metal removal techniques known... which is why Ken Perkins took the Waterjet 101 class multiple times. The caveat with plasma, is that the edges, and some additional area ( splay) will have something called "plasma slag." Remo...

A few years ago, I "captured" all of the Pietenpol sheet metal pieces, including simple pieces, and welded brackets using SolidWorks. After all of the Solid models were completed, I took them to a shop I've dealt with in the past, and they made a complete set of Piet metal pieces to prove ...

If you're rebuilding your A-65 thru IO-240 or 360, and you're going to spend some $2500+ for new parts, I'll bet you want to build it right. So, let's do a little math... Engine life of 2000 hrs. x 2100 rpm (avg.) x 60 min. per hour = 252 MILLION stress cycles! Along with Connecting Rods, these are ...

This o-200 has just been removed from a C-150 that is either being dismantled, or completely rebuilt - not exactly sure. While it is a running engine, it is being sold as a Core. REVISED ON 6/15: The engine is complete with the pull type Starter, as seen in the pics. A Core Marvel Schebler MA3SPA wi...

I'll try to address your questions one by one. Construction of a traditional wooden rib is done by first steaming & then bending the upper & lower cap strips to the shape of the airfoil. After these are made, they are connected together (glued with epoxy) using truss pieces - kinda like an o...

While you can do anything you like, both $$ and time permitting, producing NC'd ribs is much more involved than you might imagine. First, you'll need a digitized Rib, probably taken from a Rib Drawing, but there are many issues with that, as the ribs to be routed will have nearly totally different m...

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...

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...

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...

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...

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...

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 ...

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...

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....)

As in the last several years, we are bringing Continental Con Rod Bolts to Brodhead again this year. The bolts are TCM P/N 530213; they are NOS in ten packs, but we'll split them into 8, 12, etc., sets for 4 or 6 cylinder engines. These bolts fit EVERY Small Continental, from A series, to C series, ...

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 ...

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 ...

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...
