Re: Stromberg richness
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...

Re: Fueslage Modifications For Diffrent Engines.
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...

Re: Waterjetting
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...

Re: Waterjetting
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 ...

Continental Rod Bolts A, C, O Series Engines
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 ...

Re: CNC Pietenpol Ribs & More
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...

Re: CNC Pietenpol Ribs & More
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...

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...

Interesting that you should bring this up, Oscar!

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 ...

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....)
