I just read Rotor's thread asking for a source for fire brick and an idea popped in my noggin. Isn't it true that heat cannot travel thru or in a vacuum? If so, why couldn't you take a piece of pipe, weld some plate steel on one end that is bigger than the pipe. Then cut the center out to give access to the pipe. Now slide a larger diameter pipe over that assembly and weld the it to the plate with the inner pipe as centered as possible. Make the inner pipe about 2" longer than the outer. Cut a hole in a plate thats just big enough to slip over the inner pipe and weld it to the inner and outer pipe. Then drill and install some kind of nipple that you can hook to a vacuum pump and draw a vacuum between the pipes. That would suspend the inner pipe, except for the ends, in a vacuum. This a load of bs or ya think it has potential???

Mike, don't let 'em bug ya, they laughed at Edison when he built the airplane, and they laughed at the guy that invented white-out too. I love the way you think!

They reallly laughed when i chucked a wire whish in a 3/8" variable speed Black& Decker, but that's another story. (took hours to get the pie filing off the walls)
 
Robert -

The name is Nesmith. Mrs. Nesbit was in "Toy Story." She was Buzz Lightyear at Hannah's tea party.

I can honestly say that if I can remember that bit of trivia, I've watched that video TOO MANY times with my 3 year old son. LOL!

L6, it took me some time to understand what you are saying, but i get it.

Some comments: 1. Heat travels faster trough metal then trough air, so isolating the inner pipe cannot be done this way.
2. Vacuum is an illusion. There is no-place on earth with a perfect vacuum. hypothetical, it would be the perfect isolation, but the airpressure would crush you setup, even if you are a worldclass welder.
Ever heard of the vacuum-ball? It's a simple steel basketball, cut in half with a nipple on it. It is put on eachother (lined with a rubber spacer), then the inside is sucked vacuum. 10 horses pulling on each side couldn't pull the ball from eachother, while there was nothing to keep them together.

Now on the other hand, if you should fill the vacuum up with say ceramic wool, and suck that vacuum, the wool should increase in isolating potential bigtime.
Maybe a good idea for a 21st century gasforge?

Hey, my Stanley SS thermos bottle works just fine, its made out of steel.

The problem with the design is the lack of refractory, the forge burner heats up the refrac and the refrac heats the material to be forged.

Wasn't there a site posted here no to long agoshowing how to builod a heat treat oven in a wide mouth thermos?

Edison invented 1000's of things, the ones that worked he patented.

I still think it was a guy that invented white out a teacher or something, the first version was chalk from the blackboard and fingernail polish.
No I don't know why he had fingernail polish.
 
Well, it might have been a dumb idea, but it got us thinkin some. Thanks for the info and the history lessons guys!!!hmmm, maybe instead of steel plate we could use.....

First off, it's not White-Out, it's Wite-Out. Wite-Out is a correction fluid marketed by BIC.

The product you are thinking about is Liquid Paper. It was invented by Bette Nesmith Graham in the early 1950s.

Bette took a secretarial job at age 17 in 1951. Her typing skills were not particularly good. Her first batch of correction fluid was a form of white tempura paint which she used to paint over her mistakes. She began to develope the formula in her kitchen and garage, and originally named it "Mistake Out". She tried to sell the idea to IBM (who was making electric typewriters). IBM told her to take a hike. Somewhere around 1956 she changed the name to "Liquid Paper" and applied for a patent and a trademark. She started her own company and by 1975, the company employed 200 people. In 1979 the company was sold to the Gillette Corporation for $47.5 million.

By the way, Edison didn't invent the airplane either. But this is a knifemaker's forum and not a history class, so I digress.

Good thread. Funny stuff.
