If we reach a concensus, maybe we could find a shop that would give a better price if we order two or three of the same props?? I'd like to hear from everyone flying a model A and what prop they have.

Alcohol is a weak organic acid and in the presence of water will corrode many metals parts. I have been told that as little as 3% alcohol will cause problems.

The best tool I've ever seen is the Felco C-7, which sells for about $50. A friend who is an A&P here in Shreveport has one and I've used it several times for cables on the Maule. I wrote down the manufacturer and model so I could get one if I needed to do lots of cable work. Finally I found the following url: www.floridaplants.com/Store/pruners4.htm A search for Felco might give other sources which sell this product. My A&P friend reported that HF was now selling a replica of this tool for about $45-50, but I can't verify that and would not know about its quality. ...Edwin ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ ~ Edwin Johnson ....... elj@shreve.net ~ ~ http://www.shreve.net/~elj ~ ~ ~ ~ "Once you have flown, you will walk the ~ ~ earth with your eyes turned skyward, ~ ~ for there you have been, there you long ~ ~ to return." -- da Vinci ~ ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ ________________________________ Message 4 _____________________________________ Time: 10:07:30 AM PST US From: "DJ Vegh" Subject: Re: Pietenpol-List: Cable cutting --> Pietenpol-List message posted by: "DJ Vegh" AS&S has the Felco C7 for $44 I ordered mine last week.

What would you say is the optimal prop size for a Ford Piet? What's too big? I have a chance to buy one, but it looks pretty big. >> The optimal prop size depends on how much horsepower you are getting from your engine. The prop that Orin Hoopman drew plans for, dated 3/3/33, was for a 76 X 48 prop. I believe this is the size that B.H.P used on his Model A engines. It's called a 'Paddle Blade Prop', because chord is quite a bit wider at about half way out the blade. These are the plans I used to build the prop for my Model A, but mine was 75" dia. Doug Bryant used a 76 X 48 on his Piet. Stock engine, I would get about 1650 rpm during ground run - up, and unloaded in cruise flight I would get close to 1800 rpm. These are close to the numbers that Doug got. Ken Perkins (Kansas City) thought we were running too much prop for the Model A, and he uses a smaller dia and pitch, but I don't remember what it was. Therefore he would run it at a higher rpm, and take advantage of the higher horsepower above 2000 rpm. His Model A has a pressure oil system, and that is DEFINATELY the way to go. The ol' Model has potential to make good reliable power, but it has to be built to take advantage of this potential...such as pressure oil system, improved induction system, forged pistons, and a better prop flange / hub, to mention a few.
