Okay, here is a shot from many years ago when they were restoring the quadrant. You can see the item in question in the "open" position on the far right.

Yeah, It was really cool to see the old man's name in the news... It was an AP story than ran in papers all across the country. Very cool.

lol, We recently just joined a church. But before that, going to the airport was pretty much my 'religion'. Now I suppose I just have two.... :)

My phone was dead by the time I got up to the big hangar. Helped with some very important hangar doings on the other side of the airport.... Moving airplanes around, moving parts, helping bring in a beer cooler, you know, the usual... Grabbed some photos from some of the Vietnam vets...

Here's a quick shot of the new skin that has been put on the tail....

Over the last several months we have been experimenting with the best way to make these rib sections for the horizontal. It is very much a trial and error process. When these were mass produced they were able to essentially stamp these things out with no problem. Without that type of machinery around, we are forced to work every single piece like this by hand.

Fiberboard works well for building ribs like these. Use two sheets cut to the shape of the rib with holes drilled through them, sandwich a blank between them, fasten them together with bolts and wing nuts, and use a mallet to work the flanges over the sides of the form.

Believe it or not but we did almost this exact process... we made a form out of a similar type of wood with the holes in the proper spots and used it to make the channels... not only is there a lip on the channel, but there is also another channel within the channel.. we achieved that by epoxing a steel rod to the edge of the form... Unfortunately the initial forms did not hold up so we strengthened the tips with some phenalic block. The biggest problem is that each rib is different...so each one needs a different form....:-/
