Dawn Pietrol with our young hero chasing down the Red Baron -- who turns out to be a manky Scots git in a Sopwith Hamble Baby. Sadly for our hero, the strut-mounted Lewis jams whereas the Baby's Vickers are smooth and true. How will he explain it all to Group Captain Macduff?http://youtu.be/MCY4I3IJixg--Jeffrey H.

Very nice Jeff! What did you do to stiffen up the PVC pipe? I shoved a wood dowelin mine. It helps but I still get vibration. When it is cold it is stifferand I get less vibration.

Thought I'd tap into the great mass of collective wisdom here.I want to fabricate a prototype sheet metal body shell, something like you'dsee on a car from aluminum sheet. There are compound curves, but theynothing too hard.This is probably a one-off project and I can't spend the money to have bigexpensive stamping dies made, and don't want to take the time to use anEnglish wheel for it all. Does anyone know of a poor man's method to makestampings?I've seen someone take a male and female plaster or bondo mold from apattern and use a press to "stamp" our some aluminum sheets.Any thoughts are appreciated!!Douwe________________________________________________________________________________Subject: Pietenpol-List: Re: poor man's metal stamping

If you can make a concrete mold of the shape you want, and a piece of urethanepadding, you can press the shape in with a simple bottle jack press.

Douwe, you can do a poor man=92s version of a process called =93Hydroforming=94that was used at General Dynamics back in the 70=92s for some prototype parts.I used it to make some dimples in the cooling shrouds on my Pietenpol. I=92ll show how I used it to make the dimples on my cooling shrouds(eyebrows), then describe how the process can be modified.First, I=92ll show what it produced:This photo shows the rear of the right cooling shroud. I put MilleniumCylinders on my engine and the cooling fins stick out further thanContinental cylinder=92s fins, so I found I needed to modify the shroud toclear the cooling fins. I determined the shape I needed and carved a femalemold in particle board as shown below:Note the black rectangular object sitting in front of the sledgehammer.That is the key to this process. That is a block of hard rubber, 1=94 thick.That is what is used to force the aluminum into the shape of the mold, andtakes the place of a male stamping die.The aluminum sheet needs to be located over the mold and pinned in placeusing clamps or tooling holes of some kind. Then the ribber is placed overthe mold area and the sledgehammer is used to pound on the rubber, forcingthe aluminum beneath the rubber to conform to the mold, as shown below:At General Dynamics, this procedure was used on pieces as large as anautomobile hood. Of course, they used much larger (and thicker) pieces ofrubber, and a hydraulic press to form the aluminum. They could formaluminum up to =BC=94 thick.Don=92t know if this was what you had in mind, but if your pieces aren=92t toobig and the draw is not too deep, this method works well and is about as lowcost as you could ever hope for.Jack PhillipsNX899JPSmith Mountain Lake, Virginia _____

I've been thinking that perhaps the Pietenpol needs updating a bit =C3=A2=C2=C2=93 while still keeping with the designer's original intent. What better way to do that than by creating a sheet metal version of the design Love you Jake....but seriously? This is a gag, right?

Builders, If you are looking for another information resource, I have written an index ofthe 200 most popular stories on our website. They are all related to aircraftbuilding, but even if a builder was not going to use a Corvair, there are still70-80 stories that will be useful on carbs, oils, wiring, instruments, Piets,welding etc. If you have the time, peruse the titles, you can click on anyof them to read the whole story:http://flycorvair.net/2014/04/02/200-st ... lding/Vern, Lynn and myself are headed to Sun n Fun in a few hours. A number of buildersare getting together at the SPA/Panther booth of Friday night for their cookout after hours. I have forums to give On Wed. Fri. Sat. at 12 noon. I willhave a spare 24.25" Corvair/Piet mount with us. Looking forward to seeing a numberof you there.-ww.Read this topic online here:http://forums.matronics.com/viewtopic.p ... ___Subject: Pietenpol-List: Re: All sideways on the Western front
