A TR at last

I am here to support the mechanics and electricians. Working on a 777 for UAE, United Arab Emirates. I check the Chat on my break times. Can't complain about the pay on Sundays. Must pay for bad (Ferrari/BMW) habits.........................................

NOT! More like sideways. If I was I would have Oldslow 308 AND Kindaoldfast Testarossa, (yellow of course).

Dow (Magnesium Processes)
[MIL-M-3171C]
#1: A chrome pickle treatment for magnesium. Color varies from matte gray to yellow-red. Only fair corrosion resistance (less than 24 hours 20% salt spray resistance).

Magnesium is usually treated with chromate conversion coatings or an anodize finish prior to the application of organic finishes.

Magnesium must be passivated before painting. Recommendation of Dow 17 or HAE anodize (Mil-M-45202 Type I Class A) and Type I Class C, respectively, or Conversion coating (DOW 7 (Mil-M-3171 Type III or VIII) or or DOW 19 (Mil-M-3171 Type VI).

Here is a handy site for determining what processes to use for which alloys, http://www.cygnetstamping.com/coating.html

Is this what you were looking for?

PM Steve Magnusson HERE to find out where on your car this may be. Rear hubs maybe?

How'd ya like that Rube Goldberg cable system? Mine has the same thing.

I see you subscribe to the "A clean car is a happy car" school. Cleaning the entire underside was the first thing I did with mine. Car on jack stands 18" high, Simple Green and a light duty pressure washer. I came out from under a few hours later soaked like a rat from Titanic. Amazing I didn't electrocute myself from the electric lights laying under there with me.

I dunno, maybe it would have made me smarter.

Right now I am sitting 15 feet away from a 777 while the crew installs the cargo handling system and associated electrical. They holler when they're done and I go in to see if it looks like it does on the drawings.......................err, at least thats the official description.

 

Actually, at least as far as I know, Ferrari wheels are NOT just your plain Jane aluminum alloy, they aren't on my 308 either. They are lighter than the reproduction 16" aluminum rims I am running on it now. Not sure of the exact alloy but I thought I heard they had some magnesium in them. I'm sure somebody knows for sure around here. Steve Magnusson comes to mind.

Yeah, the 777 is a good performer, faster and burns less fuel than it's closest competitor. The 787 will have even better power to weight ratio. Mostly composite. The fuselage sections are spun in one piece out of carbon fiber like a big paper towel tube. Cut the windows in later. Empanage will be composite as well. I will see about cutting over to that line when production ramps up. Thats where the money is at.

 

Thanks, Steve. I was one of the first technical designers that started that airplane in 1987 and we did it all on the Catia computer system. First time ever for that to be done. My last job for Boeing was the configuration drawing for the 777-300 also on the computer. Very proud of that airplane. Some airline people refer to it as the WGA....World's Greatest Airplane.

 

Ferrari wheels have a very high Mag content and are sealed before painted. As I recall in that period the sealer looked like a green chromate kind of thing.

 

Sparky, theres your answer. Chrome Pickle is what you see. Applied before they sprayed your wheels with color.

 

I ain't the computer guru that I sound like. The Catia was a monster nitemare and I was in trouble most of the time but I confused it as much as it confused me. I started at work for Boeing on October 4th, 1950 as a flightline modification mechanic and did my last job on August 8th 2003 as a technical designer in Preliminary Design. I fooled a helluva lot of people on the way. I worked on everything from the B-52 on up to the 777.I'm scheduled to give a talk at Boeing on my experiences with the 367-80, the 707 protoype, on which I worked in 1954. Geeze, I can tell a lot of stories. Hardly anybody believes them now.

Art was a lucky guy. Got to live a life few do.


That undercoating is soluable with solvent. Gas really works great but that is a little too dangerous.

If you think that car is 10 lbs in a 5 lb bag you should see the new ones.

I think they had Ray Charles spraying the undercoating. I wish we could have ordered cars without it. Out here we just dont need it. Half the Ferrari's in Ca have never even seen water, much less salt.

 

R&D HELL, just a lot of wine and cheese on extended lunch breaks. 308 the same way. Have to call little neighbor kids over to stick their paws in the tight places on the car. No corrosion resistance on early 308's either. I think I would rather deal with pesky undercoating than cancer.

It's the least I can do for those swell Jelly Belly Sparkplug shirts.

CF wings too. Really amazing. Bypass ratio on the engines is being increased also.

R.I.P.

Yes, I was there when Tex rolled the -80. The first one was to the north and I yelled , " He did a barrel roll!" The guy next to me said that they couldn't roll an airplane that big. So Tex came back going south and did another one. No comment from my neighbor. That picture from inside was taken by the flight engineer, Bryan Mahon, who was a real engineer on the project. He said that it was one G all the way around and he closed his eyes and couldn't tell the difference from normal flight on the second roll. It had to have been one G or they would have lost oil pressure on the constant speed drives and filled the fuel vent system in the wings with fuel and probably siphoned everything out before they could get back to the field. They practiced the rolls a few times before they did it over the race course. Tex Johnston was on the carpet in Bill Allen's office for a solid week, I heard. Their insurance policy would have been void if something had happened to their 13 million dollar gamble but his maneuver sold a lot of airplanes. I saw test pilots roll production 707's a few times and the 747 was a fully aerobatic airplane too . Proved that with the immelman atomic bomb drop.

 

CORRECTION ! I have civil transports in my head when I was talking about military. I meant to say B-47 doing an Immelman to deliver the atom warhead, the " Over the Shoulder Toss " or " Lob Toss ". Boeing builds them damn good.

I may have to cancel my B-17 resto project and simply anty up the big bucks.
Who's willing to give me a handout?

I'm sure it's BIG BUCKS for the B-17. Pretty high hours on the engines. The yellow paint looks rather odd. I wonder if it is accurate?

This is one of my favorites, A26 Invader. Better with the solid nose full of 50's though.

This post off-topic, but having seen firsthand the interest in WWII aviation here, I thought some of you might be interested in this.

It's a book, _Wings of Morning_, by a local (for me, anyway) author named Thomas Childers. It's gotten positive reviews and I can say it makes for a good afternoon/evening read.

Thanks Chris.

 

Holy Cow! We just got our first frost last night. Mostly heavy monsoon for the last two weeks but heavy snow in the Cascades. Ski resorts are happy.
If the snow level rises above 5,000 and starts raining up there it is going to be a real flood down here. Happed before. BIG mess.

 

I was looking at all the ordinance you could load on those things. Almost as much as an early B-17 in lbs.

I heard they were good at loitering until ground support was needed, happy troops when they cleaned house on the bad guys.
