Bill RV-7 fuse & finish Lee's Summit, MO Bill, Maybe someone will give you an exact answer, but speaking from experience: Wait until you fit the wings on and project the leading edge to the fuselage with a yardstick, or draw around the fairing. Just be sure to keep the large washer inside of the fairing outline, and look on the inside of the cabin to be sure you have a clear area there. I had to "move" mine after finding that I had it so low that the washer projected below the wing leading edge on the bottom.

A small aquarium style pump is really handy for transferring your Alodine and AlumiPrep chemicals from the dip tanks back to their storage containers. I would also empty my rinse water tank with this pump, to ensure that I had not left acid inside the pump. It will last longer that way. Remember that Alodine is photo chemically reactive. Don't use it out in the sun, or it will be ruined. By this, I mean that the next time you use it, nothing will happen. Do it in your garage or shop with the door and/or windows open.

Now what are the aerodynamics involved? > >Ivan McLaws I have a theory, but I don't know whether it is the right answer or not. At the trailing edge, the air on the bottom has a tendency to follow the radius (Conada Effect). The larger the trailing edge radius, the greater the tendency the air has to go around the radius. The little bit of lower surface air that follows the radius ends up changing its direction upwards. It takes a force to cause the air to change direction, and the equal and opposite reaction is felt on the aileron, which has a tendency to deflect downwards. This tends to lift that wing. Of course the aileron on the other side is doing the same thing, but they are connected. Whichever aileron has the larger trailing edge radius overpowers the other one. The obvious question is what about the air on the top of the wing? It should be doing the same thing, and in the other direction. On the upper surface, the air velocity is maximum nearer the leading edge, and the air is slowing down as it approaches the trailing edge. This means that the air pressure is increasing as you move aft (Bernoulli tells us that the air pressure increases as the air slows down). So, the air is moving from an area of low pressure towards an area of higher pressure. It doesn't like to do that, so it slows down, which increases the boundary layer thickness. I believe that the boundary layer on the aft part of the upper surface is thicker than the boundary layer on the aft part of the lower surface, as the upper surface has a more adverse pressure gradient. This means that the air right next to the skin on the aft part of the wing is going slower on the upper surface than it is on the lower surface, so the Coanada effect would be greater on the lower surface. This is just my personal theory. It might be right or wrong. http://jnaudin.free.fr/html/coanda.htm -- Kevin Horton RV-8 (finishing kit) Ottawa, Canada http://www.kilohotel.com ________________________________ Message 12 ____________________________________ Time: 03:39:16 PM PST US From: Jeff Point Subject: Re: RV-List: Heavy Wing --> RV-List message posted by: Jeff Point I'm surprised that they told you to do this first. Who did you talk to at Van's? They have a FAQ for this very common problem on their website: http://www.vansaircraft.com/pdf/Wing_Heavy.pdf The short version is this: "squeezing" the ailerons is the last thing to do. Rechecking all of the alignment of the wings, stabilizers, fairings etc. The other biggie is check the aileron alignment relative to the wing. I did and found that the leading edge of the "light" wing aileron was sticking down into the slipstream about 1/8 inch or so. A new pair of aileron brackets for ten bucks and an hour of work and the problem was solved, with no squeezing involved. If you squeeze an aileron, unless the aileron itself was causing the problem, you are just covering up a problem elsewhere, and adding unnecessary drag in the process. Read the FAQ sheet, it does a good job of explaining the whole process.

It is a nasty chemical if the exposre is acute (large ingestion) or chronic (working with it regularly). However, its not one of those touch-and-die things. But no benefit comes from exposure through ingestion or absorption. The chance of getting cancer from spilling it on your leg or arms a few times is about the same as the odds of getting hit by a meteor, or a crashing Challenger jet landing on your head (ooops, actually, the odds are a lot less then that!). Nonetheless, the only true safe exposure is no exposure, so wear gloves and don't take a bath in it. The sun (after a while) will change hexavalent to trivalent chromates, which are safe, but ineffectual for the intended purpose.

It should be stressed. It's takes VERY LITTLE squeeze to lift the light wing. We used sheet metal "duck bills" as the jaws close parallel rather than alligator or scissor style pliers. We put duck tape on the jaws to protect the finish. IF you "feel" the edge give when you squeeze it's TOO MUCH. VERY VERY VERY little force needs to be applied. The "duck bills" we used are about 5" wide and you squeeze the entire length VERY VERY little. We did it twice on N561FS to get it perfect. We didn't "wack" the heavy wing at all, didn't need to. This post has lots of VERY'S in for a VERY good reason. Go slow.
