I haven't..... but I did get a prop from Tennesee Props. WOW! what a qualitypiece! It was made from 48 1/16th" laminations. yes thats right! 48 laminations. Clear urethane leading edges and shipped to my door for $530.In my opinion it's one of the best props out there for that price. The qualityrivals that of a certified wood prop.www.tn-prop.comDJ Vegh----- Original Message -----

Subject: Re: Pietenpol-List: prop infoKen,In answer to your inquiry of Hegy props I can say yes I have one on 41CC. It is birch and is a very beautiful piece of workmanship. Mr Hegy and I decided a72-42 would be the most efficient for a Piet with a 65 Continental. We are happy with the performance. His price was $500 plus Fed Ex.Corky in LaBy the way, on another subject, have any of you noticed the total absence of any discussion by our leaders,????????????????????????, Aopa, Eaa, Aarp, Naacp, or any other of the nationals who are so dedicated, with the help of ourannuals, to helping us with all kinds of small problems, on the proposed SportPilot ruling. Someone somewhere decided to sweep in under the rug for awhile. Something's going on and I really don't like the scent of it. Better get our Congressional address book out again and lick some stampsCorky in La again, running out of time________________________________________________________________________________

For a long time, I've been considering building a Scimitar prop, using the method described in the Eric Cluton's guidlines. Do you know anyone that built this Scimitar prop ??Chuck Gantzer________________________________________________________________________________Date: Fri, 17 Oct 2003 09:51:50 -0400

He's British. You can get it from EAA library, and it only costs about8 bucks or so. It is a MUST READ TWICE if you are even thinking about building a prop. He gives building methods & tips, and all the formulas for estimating the pitch and diameter for a given horsepower / airframe, but he notesa preferred method is to use previous a successful combination of Prop / Powerplant/ Airframe. He goes into detail how to build a Scimitar Prop - where the blade tips are swept back quite a bit. I've done some research on this type of prop, butfor the life of me I can't figure out why everybody doesn't use this design prop. There are six Scimitar Props hanging in Steve Wittman's hanger. It's like an automatic blade pitch, with no moving parts. At high R.P.M. for take off, using cintrifugal force and aerodynamic twisting force the wood prop bladeangle is reduced for more thrust. When airborn and power is reduced, the prop'unloads', the blade angle relax's and you have a higher blade angle for more efficient cruise. What more could you want ??? !!! To be honest, it would require quite a bit more work to build one using the 'Cluton' method, and I suppose with all the flexing the blades are exposed to, there would be more ofa chance for a blade to fail. I did read one story about a W W 1 pilot that had a Scimitar prop. It seems his opponent was on his tail slinging lead at him, so he went into a fullpower dive. Overspeed the engine, and over ran the prop when the blades beganto 'flutter' just before a blade failed and broke off. He was having a bad day. Not sure if he made it.Chuck G.________________________________________________________________________________

Subject: Re: Pietenpol-List: prop infoChuck...I don't know if this is the kind of input you want at this stage, but I have a 3/4 scale reproduction of a 1917 Paragon propeller which was hand carved from mahogany by the guy I bought a Pietenpol project from. It is a scimitar which is 75" long. I understand that the original propeller was used onan airship. I have a picture of it, but no data. I don't see how this can be of much help to you except inspiration...It's beautiful.....Carl Vought.....do not archive________________________________________________________________________________

I forgot to mention (about my Tennessee Props prop) that I have painted the prop tips yellow to provide a visible arc to help ground recognition when the engine is running, and also painted the backsides of the blades flat black to cut any glare or reflections back into my eyes.Wouldn't want to lose sight of Der Faker Fokker in my gunsights ahead if there is some glare off the prop ;o)Oscar ZunigaSan Antonio, TXmailto: taildrags(at)hotmail.comwebsite at http://www.flysquirrel.netNever get a busy signal because you are always connected with high-speed Internet access.
