I talked to Anne at Van's Friday (5-02-08). She said that the ship date for my wing kit is 3 weeks away. My S/N is 027. I guess I better start on those work tables.

Thanks for this. I'm number 33. Although it will take a while to ship mine to the UK, I have ordered the Avery tools kit and am sorting out the mess in my garage.

Does anyone have have recommendations on sound deadening material to surround a compressor with? I'm thinking of using a smaller scale variation of the EAA workbench to install workbench tools on, and to enclose the compressor on the shelf underneath.

Thanks...Keith

Dan Checkoway did a write-up on sound reduction at http://www.rvproject.com/compressor.html

I decided to use a little different approach. Instead of building the "box" like others have, I decided to put a better muffler on the air intake. Why?...because the biggest offender on any air compressor is the large acoustic impulses caused by the compressor as it takes big bites of air when the compressor piston goes down. This made a 4 db improvement and sounded much better. Probably not as good as a box, but lots easier, and it is still easily transportable and serviceable. My 22 year old son heard the new muffler and easily noticed the difference.

The muffler usually screws on the compressor via 1/2 inch steel nipple (pipe) that is about 3 inches long. It's easy to build an larger muffler from 4 inch pvc pipe and screw it into the 1/2 inch nipple.

There are some other noises comming from the compressor, but the intake is definitly the worst.

If anyone wants, I can post a description of how I made my muffler.

I spoke to Van's Aircraft and with #003, my wings are due this week.

Is it recommended to prime the spar, ribs and inside skin surfaces? If it is, that'll really slow things down. What is everyone doing? To prime or not to prime,

that is the question.

The spar is anodized, so you shouldn't need to prime that at all. Everything else is up to you, as best I can tell. I think most would agree that non-alclad parts should be primed, at the very least.

Beyond that, it comes down to what you're comfortable with. I live in well away from the ocean, so I'm not overly concerned about interior corrosion. I will probably limit my treatment to ribs, mating surfaces, and any non-alclad metal, but that's just my choice. I have no doubt that others would prime everything, while some would just bolt everything together exactly as it came from the factory. Since weight is such an issue for these planes, I'm doing the bare minimum that I'm comfortable with, and documenting everything so future buyers/fliers can decide if it meets their needs.

From what I hear from Floridians, though, anti-corrosion treatment is something of a necessity out there. I'm sure some locals will chime in with some thoughts for you.

Jerry.. The manual says that the skins are alclad which "need not be primed" ... "However, it the airplane is to be kept in a salt-air environment, or if a greater margin of corrosion protection is desired, priming the inside of the airframe is a good idea. Remember that priming will add cost, weight and time to your project." The manual goes on to say "the pre-assembled spars are anodized and need no additional protection. All aluminum bar, angle, and tube used in the RV-12 is not alclad and must be primed to assure corrosion resistance..."

Sarasota International Airport, where I plan on sharing a hanger with someone (anyone), is about 1/2 mile away from the (salty) Gulf of Mexico.

I guess that answers my question ...

Well, I knew I wasn't going to break any records with my build time anyway.

I did like the fact that there was still 25 lbs. of useful load remaining with a full tank and myself and my wife aboard. One or two gallons of paint will put an end to that.

I guess "Weight Watchers" is my future. (I hate the thought of reducing good food to points).

My wing Kit is enroute and should be delivered Monday according ABS Bill of Lading.
I live on the Gulf Coast and will either prime or fog airframe with Corrosion X. I would advise anyone who plans to leave aircraft out of doors near salt water to prime.
