Pietenpol-List: Vasek's production of Historic Propellers

Vasek,Given that those engines are not common in Europe (I would love to visit the Czech Republic some day, most people do not realize your country's contributions to European & western culture), I might suggest that you seek out a water-cooled 4-cylinder engine that has a power curve similar to the Ford Model A, either inherently, or by installing a modified cam. There are many of these available - modern Ford engines like the Fiesta and Pinto, possibly the 4-cylinder engine that powered Toyota Trucks in the late 1970's - early 1980's period, engines from any number of European cars (Fiat, perhaps?). You would convert these very similarly to converting the Model A, so you would have a a path to follow. I was considering doing this with my old Toyota truck engine until I lucked onto a free Corvair engine.Kip GardnerOn Mar 2, 2014, at 5:00 PM, Vasek wrote:>> Fords and Corvairs and not very common here in Europe, so I am > searching for alternatives

Wow Vasek those props are magnificent! I really admire you for being able to carve those beauties, and to be able to make it into a business for yourself is a huge bonus. Good for you and your friends. Wishing you all the best!Dan HelsperPuryear, TN-----Original Message-----

John; there are ways to do it in the air, using the GPS, but to me it's easierto do it on the ground with a compass rose than in the air.Steve; well, duh... notice that I mentioned the brass screwdriver in my post? ;o) Also, you don't describe the procedure quite right. You only take out halfthe difference when you turn to the S and W headings.Jack; believe me, I have noticed the very effect that you mention, with the compassslowly moving away from heading if the stick is moved closer or farther fromthe compass. Duly noted, sir!--------Oscar ZunigaMedford, ORAir Camper NX41CC "Scout"A75 powerRead this topic online here:http://forums.matronics.com/viewtopic.p ... ___Subject: Pietenpol-List: Re: Vasek's production of Historic Propellers

Thank you for the nice words, I very appreciate it. I can post photos of some ofour interesting projects if you wish. We will have a four-blade propeller fromR.E.8 soon in the "old style" and a big beautiful Chauviere prop from D.H.1.> Perhaps your Piet should have some styling to remind us of a pre WWII Avia orLetov. It definitely could have! Do you have any suggestions?> Are there any old Waltor Minor engines floating around? they are somewhat comparableto at Contental O200 while about 30 pounds heavier. Yes, I think that I could find some, but I have a feedback from a guy who had GN-1that the Walter was too weak. He replaced it with Subaru with a reductiondrive.> There is no reason that you could not break into the Prop or construction business.The question is, would people be interested in these carved propellers? I mean,airworthy? Such a prop would be at least three times more expensive than it isnow.--------My production of WW1 propellers, trophies and constructions:Read this topic online here:http://forums.matronics.com/viewtopic.p ... __________
