Motorcycle production in the 1950s
Re: Motorcycle production in the 1950s
The only process I know that chucks out a lot of sparks and debris is air arcing but I can't think of any reason in the World they'd be using air arc as part of a production line.

There's a very good reason why I ended up working on turbines and my ability as a welder didn't come into it :whistle:

The commercial B&W films then were quite slow by modern standards hence the spark trails from a few micro seconds exposure.
End of rod is also blurred indicating slow film.
They are wearing dark lenses.
These swing arms have been tacked up on a jig with these guys doing a full finishing weld.
Lightness is everything.
Lightness with Grunt is a Scratcher!

Maybe I did remember something from my apprenticeship correctly
We had to learn all the different processes in the first year before deciding where we wanted to end up and that covered fitting, fabrication and machining but only the basics so both the apprentice and the employer knew where we'd be best suited.
If only I'd known then what I know now I'd never have walked in through those gates back in 1975.
