Yes, it looks like we'll have to get involved in the reproduction of wing attach hinge fittings also. I have a couple of virgin hinge fitting. Regards, John

Great news John! I remember seeing a couple of virgin wing hinge fittings at Tom Reilly's place a few years back. I also have a photo somewhere from the production line where they actually did the final facing on the hinge mating areas when they were attached to a virtually complete fuselage. Quite fascinating... I guess that's how they made sure the outer wings were aligned properly with the inners. That's going to be a lot of work, but it's exciting to know that it's actively being contemplated.

Cheers,

If anyone can make a new spar it would be the guys at Wangarratta they have made a large investment in the plant and talent needed for a project like this.

As for who owns what and where it comes from, most info is in the latest issue of classic wings.

better question might be is " are you setting up that any more new ones needed in the future are already organised on CAD and CAM for manufacturing?

Prehaps we all ought to but a second subscription to Warbird Digest.. LOL!

Check out the current projects!

Funny.. I don't remember saying that I think this is another case of a reporter stretching the truth just a hair

Of course...that second subscription to Warbird Digest is a great idea...I am sure there is someone on your Christmas list that just has to have it

Hey ya'll,
I know this sounds kooky but what about wood spars for the F4U Corsair?
When I was a kid a local guy bought a kit to build a 1/2 scale W.A.R. Corsair replica. It had a spar with the distinctive gull shape cut from a single block of Spruce and it had the front and backs capped with aviation grade birch plywood glued and tacked on it. The wing folding hinges and the scaled landing gear fit nicely bolted on the spars. The project sold before it was finished. I believe there are a few of those replicas flying now. There is a 1/2 scale W.A.R. FW-190 in trade-a-plane right now.
As far as size differences, how much difference would there be to achieve satisfactory strength? I've flown pre-war Cubs and Chiefs with wooden spars and post war equivalents and the only difference I can tell is the wooden spar'd aircraft make three point landings a little sweeter.
Another thought, thinking back in time, Cessna built the Bamboo bomber, Stinson had their tri-motors, Fairchild and even Dehavilland built some pretty capable designs with wooden spars. Remember the Mosquito?!!!

I think that the Vengeance (and maybe the Kingfisher) listed are for Whale World.

From not for.

Hi Marine Air:

I suppose it's physically possible to do it, but it would probably require stress calcs.. In addition to a strong enough need to get the plane in the air..

The wooden spar is one alternative, but I'm not sure what the long term duration would be. Another alternative might be to use"CARBON FIBER" to reproce the spar. Would be light then aluminum and stronger than steel. The Space Ship One and the Thunder mustangs are made of carbon fiber. So just food for thought.

The WAR replica may be 1/2 the size. But more importantly it is 1/10 the weight or less. Not a realistic alternative in this situation. As for carbon fiber. I think it would amount to more work in engineering and production than replicating the VOUGHT design. Even if you did it, then you would have a unproven design of mixed construction aluminum/carbon.Unless you plan to build the rest of the airplane from carbon fiber as well. BOEING even has trouble integrating the two materials, They have dissimilar coefficient of expansions with varying temperatures. I dont believe the corsair spar issue will be solved on a chat board, but in the shops of restorers and the wallets of those who pay people to solve the problems. I wish Mr.LANE and his associates much luck with the project. The CORSAIR world couldn't find a better leader for the project.
