    Subject: Re: Wood props and IFR
    --> RV-List message posted by: "Jim Nolan" <jamespnolan@earthlink.net> Dj, I flew IFR with a wood prop the first two years I had my ticket. To make a long story short, I had to refinish my prop three times in two years. The fact that I slowed the engine to less than 2000 rpm in rain probably saved me from refinishing it more often. I finally broke down and bought a Sensenich metal prop. I've been happy with it so far and the peace of mind you get is priceless. I once informed Indy ATC that I had to slow down because I had a wood prop and I was in heavy rain. The woman responded with " Do you want to declare an emergency" Jim Nolan N444JN

You had fun typing that post didn't ya:-) No discredit intended, that was some impressive thinking. While we both thought of a process along these lines we dismissed it as far too complicated for what we have in mind, with "what we have in mind" as the emphasis. Great ideas but a little too much for what we want. All we want is a nice custom panel with extended center console for controls and wrap around left and right bottom corners to fully encase the air vent of choice. Plus, we want to be able to do it in a weekend:-) We'll have something in a couple weeks, I'm sure. The cost to look factor is going to be impressive.

It attaches to the 4 pipe tubes (2 each side) and the outboard corner bolts of the sump. I do have a wood prop and balance ring installed. Perhaps the failures are prop vibration issues Stewart RV4 Colorado

I have a Ted Hendrickson wooden prop on my plane, and I'd like to start training for my instrument rating. I've read that wood props don't like the rain, and get beat up pretty badly. Basically, I'm wondering is a little rain going to really trash the prop, or would it take hours and hours of rain flying to cause damage? The prop has about 1050 hours on it, but was freshly refurbished by Sensenich about 50 hours ago, nice fresh clear coat, looks beautiful. Thanks, -Dj

    --> RV-List message posted by: Charlie England <cengland@netdoor.com> -7/-8 builders, Has anyone noticed a slight dip about an inch above & below (back of the actual apex) the rolled leading edge of their tank skins & leading edge skins? While handling one of my cleco'd tanks, I felt the dip, & thought I had somehow dented the leading edge. On further inspection, the 'dips' are slight valleys running the entire length of the LE & are identical on all 4 skins. On the top side, it's about where the 2nd rivet will be in each rib. It seems unlikely that it's due to the ribs, because there is no difference in the valley mid way between ribs. I might be good at messing stuff up, but I ain't THAT good. Thanks, Charlie

    --> RV-List message posted by: Oldsfolks@aol.com Rain will definitely ruin a wood prop. On one of our first flights in our RV-4 ,we were flying with another RV-4. I had the urethane leading edge and the other had just clear tape. After 3 1/2 hours @ 1800 RPM I had only minor chipping on the paint edges at the tip ; the other had about 1/4" of the wood chewed off the leading edge ! One trashed prop.

    --> RV-List message posted by: "JOHN STARN" <jhstarn@verizon.net> The official count was 26 RV's with one HRII flown in. We at EAA 768 also had three Young Eagle flights, made room for the Short Wing Piper club, 7 fly-in's for them. Several other production types mixed with the Arco guys and the "usual APV suspects". We were missing only an RV-3, HR-1, F-1 and an HRIII to have had a complete set of ALL the RV types. We refer to 561FS as an RV-4 on steroids. If you missed out on the feed and the talk, TOUGH TOE NAILS. We had a great time and will hold another "informal" RV fly-in feed for all those that missed out this time. Friday was also a good day at APV. Got 561FS's test flights completed on the new engine and the "quad" prop. When was the last time you saw 5 Howards and a Ryan land at your airport during the week. Apple Valley Airport is just a great place to spend flying or hanger time. If anyone who attended didn't get enough to eat, that was your fault. Ron Caraway cooked up just about everything we had but it was good to the last bite. Thanks to all for the great examples of RV's and the hanger "flying".

How well does its light cover the instrument? How bright is the illumination? What actually is the cost?

    Subject: -7 wing leading edge 'glitch' ?
    --> RV-List message posted by: "Youne Hippoman" <youne.hippoman@sympatico.ca> Yes. I have dips above and below, on both leading edges and both fuel tanks skins. This is normal and has nothing to do with the ribs. It happens because the apex part of the skin is a permanent curve (machine formed) in the aluminium structure whereas the aft top and bottom curves are temporary (i.e. if you remove the clecoes, the skin opens back to a 90 degree angle). When the skin is left open, there is absolutely no dip at all. But, when we force the skin to fold, a bulge is formed where the permanent and the temporary curves meet. Blame it on molecular structure memory, not Van's!!! In theory, if we keep on forcing the skin to fold (don't do that, it may create permanent damage to the skin), we will reach a point where the dip will disappear. But, the plane won't fly with such a wing profile!!! I would rather keep the bulge and fly the plane. You will also notice the same dip in the rudder skin, but it's harder to detect because it is less deep. You may need a couple of drinks with the lights turned off in order to feel the dip in the rudder skin.

    Subject: Van's alternator - $18 at Pep boys
    From: "Stewart, Michael (ISS Atlanta)" <mstewart@iss.net>
    --> RV-List message posted by: "Stewart, Michael (ISS Atlanta)" <mstewart@iss.net> Dan, Its off a 1989 Suzuki Samurai. You will find many references to it in the archives. You will need to modify the existing vans bracket but it is no big deal. Mike Do not archive. -----Original Message----- From: owner-rv-list-server@matronics.com [mailto:owner-rv-list-server@matronics.com] On Behalf Of Hopperdhh@aol.com Subject: Re: RV-List: Van's alternator - $18 at Pep boys --> RV-List message posted by: Hopperdhh@aol.com Mike, What is the part number of your Susuki 60 amp alternator?
