B-52 GUNNER

OK, Guys Here it is. I got the two together and can get it to 28 inches of mercury. However it has a very slow leak. How do you find the leak and it there a easy way to stop it? Scot

Valkyrie or Cobywan, Would you think I can drill a hole through the side of the pressure cooker pot in order to attach the compressor to the side? Otherwise I would have to attach it to the lid. Scot

Thanks for the help Valkyrie. Now I'm going to find a gasket and the fittings to mount the two together. So it may be a few days before I post any progress. Scot Man this is COOL!

Valkyrie and Cobywan, I attached the PIAB vacuum gauge to the compressor and I got 28 inches of mercury. Is that enough to degas resin? Scot

I'M STILL ALIVE!!!! It was the one on the top that is the intake It does leak oil from the exhaust. I wonder if the oil can be left to leak or does the compressor need it? What I need to do is to create a reservware to containt the oil and it should seep back into the compressor. Scot

Now I'm worried If you don't hear back from me... It was nice knowing you Will anything come out of the other pipe? Scot

Here's a close-up of the compressor. The tube on the lower left is sealed with solder. So I beleave the long tube curving around on the top and the short tube on the lower right are the ones in question? Which one is the intake tube? I may plug the holes in the lid and drill and tap a new hole in the side of the pot so it would be easier to open the lid. Scot

Valkyrie, OK, Here's the REAL IMPORTANT QUESTION!! Which tube is which? Thanks in advance, Scot

Here is a photo of my pressure cooker pot and the refridgerator compressor. I have a PIAB vacuum gauge and a compressor coupling attached to the lid. Can anyone tell me the best way to attach the compressor to the pressure cooker?

My Dad was in Nam as a Gunner in 70". Making monkey meat and tooth picks. (Bombing Jungle) But he was a Radar Tech for Recon Drones in 65" 66" 67". Cool FireBee Drones; But that's another story. So back to the main topic: RESIN CASTING!!! Help me Cobywan , Your my only hope!! I need a reply on the last 2 questions I posted PLEASE!!!!!!! Scot

My Dad was a B-52 Gunner from 66' to 78' where he retired from Castle AFB as an Instructor. He served before, during, and after Vietnam; mostly during the cold war flying with pretty silver cylinders in the bomb bay. During Vietnam, two Gunners shot down Migs. Afterwards the Gunners were allowed to keep one of the barrels from their tail gun. If you ever goto the U.S. Air Force Museum in Fairborn, Ohio they have one of the barrels on display. The B-52 had a .50 cal. Quad Cannon in the tail until I think the G and H models when they had 20mm Vulcan Cannons I beleave. One final note: When you hear people call the B-52 "B.U.F.F." (Big Ugly Fat Fellow) they are wrong. The real nick name is "B.U.F" for (Big Ugly F****r).

Also, What type of material would you use to make the original out of in order to make the mold. I was thinking of using aluminum. Scot

Cobywan, How much would a piece of 1" thick clear acrylic cost? It would have to be 1.5' square. Also, If I wanted to make the highest quality lenses what type of clear resin do you recommend? Scot

Cobywan, I was thinking about using the lid that came with the Presure Cooker because I can mount the gauge to it directly. I know that the reason for having the clear top is to see when the degassing is complete, but for what I'm going to be using it for I can just create the vacuum and then let it sit for several minutes. Would that be ok to do or should I still get the clear top? Scot

Cobywan, Here is a photo of my pressure cooker pot. It has grind marks on the sides that make it look like it's cast aluminum. I also have a PIAB vacuum gauge attached to the lid. Would this hold up to 28.0 to 30.0 inches of mercury better than the sheet metal pots you told us about? If the picture is too large I'll edit it. Scot

Thanks Guys for all your advice. I contacted the guy who made the vacuum chamber out of a presure cooker pot and I am waiting to here from him. He has a website: Small Art Works and he makes some very high quality models so I hope he knows what he is doing. As for my name here on Macross World... My Dad was a B-52 Gunner and I took that name to honor him. I do have access to friends that work at General Motors tooling dept. and at General Electrics Jet engine plant that can make me small parts. I was also wondering if you can use a PIAB Vacuum generator to produce the 28.0 to 30.0 inches of mercury needed to degas the RTV and resin? Thanks again, Scot

tom64ss, Thanks, but it doesn't say anything about Vacuum Chambers. Do you know anything about degassing? Scot

Hey Guys, I was wondering if anyone could give me step by step instructions on how to resin cast. I read an artical in FineScale Modeler about how this guy made a vacuum chamber out of a pressure cooker pot and a refidgerator compressor. Has anyone made one of these before? If so, how do you put it together? If not, What do you use to degas your TV and resin? I'd also like to know where you can find supplies cheap. Thanks in advance, Scot

All I have to say is

You could buy 2 and make a U.S.S. RELIANT NCC-1864

NCC-1701 Motion Picture Enterprise It looks to be 3 feet long

OK guys, Let's see who can color this image. Scot

Since when did the Air Force get Aircraft Carriers?

The X & Y B-52's had a fighter style cockpit until Gen. Curtis E. LeMay said it was best for the bomber crew to work side by side. It makes communications easier.
