Tig welding in vacuum

[jordan1]

Was mentioned a while back about Tig welding in a vacuum. Just reading an old 1966 Motorcycle mag and came across this article welding the frame of a BSA competition scrambler in a vacuum chamber. Interesting.

Dunsfold had chambers like that, infact a welder near me that did a lot of work for the helicopter place next door made one.
I never looked at the one near me but when I was last in Dunsfold we had a good look at one, it was basically an old oil drum with a vent at the top.

Was the competition frame a titanium Goldie frames? I used to do work for a Goldstar specialist, he had a cracked titanium frame on his wall, he said
the problem was they broke whatever the frames were made of, but you couldn't braze up a titanium frame in a field.
