He has a C 180 and and a 220 HP Stintson, both planes have installed "the spring" because most (if not all) of the strips are no second chance up there. Both planes are kept in pristine condition always, sometimes I have the chance to help working in his airplanes. I dont know what carburator they have... Saludos Gary Gower.

I went out flying today, using a runway with no good emergency landing spots on the departure end. Sitting around the hangar chatting later, that subject came up and it sounded like a good idea.

Two reasons... one is accurate control of temperature, the other is even temperatures across the face of the iron. A third reason might be "enough power", to keep the iron at the right temperature while you're covering a large area. It's very important to use the exact temperatures spelled out in the manual. Besides, the iron they recommend only costs $30 or so. It happened that my wife uses one of the recommended irons and I was able to use hers for the large areas when I recovered my vertical stabilizer, then I bought one of the small irons from Wicks to use for corners and for heat-smoothing. It's been very valuable for the small repair patches I've had to do on 41CC as well. I calibrated it, made marks on the dial, and it works great. Both my wife's iron and the smaller one that I bought have the "ironstone" type non-stick coating on them so they don't get messed up with the covering materials.

No, but I've thought about it. The way my controls are set up, it would take a very stout spring to do that (figuring on worst case for a failure, at the pilot's throttle control end, the spring having to overcome the friction of the entire control string from end to end). I thought about some type of circular spring around the throttle shaft pivot as is used in some hedge clippers, but the easiest would be a regular coil spring. The problem becomes that the friction on the throttle controls then needs to be increased to hold a normal power setting against the spring. When you figure it out, tell me how you did it ;o) Oscar Zuniga San Antonio, TX mailto: taildrags@hotmail.com website at http://www.flysquirrel.net ________________________________ Message 4 _____________________________________ Time: 02:20:58 PM PST US Subject: RE: Pietenpol-List: Re: cable vibration--tailsection From: --> Pietenpol-List message posted by: I sent pics to your personal address;you can't send pics on this web site.Enjoy! -----Original Message----- From: owner-pietenpol-list-server@matronics.com [mailto:owner-pietenpol-list-server@matronics.com] On Behalf Of Barry Davis Sent: June 2, 2006 1:29 PM Subject: Re: Pietenpol-List: Re: cable vibration--tailsection --> Pietenpol-List message posted by: "Barry Davis" Harv How did you make your rod style braces?

Just with the force enough to move the thottle if the cable brakes. The worse friction it needs to pull is if the control cable brakes in the handle side. This is similar to the force needed to pull a free cable from a front brake of a mountain bicicle. Just to make yourself an idea. The friction needed to overcome the spring is just very little. Sont use a heavier spring than needed it will only aply unnecesary force and friction to the buterfly axle... Here you can find spring shops that will coustom make all type of springs, some of them the have in shelves, hand pull a hand full and test/try until you find the correct one... Just a few bucks. I dont know if there are this type of spring shops in USA, I am sure they can be found. Saludos Gary Gower.
