An Elfin 100-related story...
Brian Rawlings, who was to go on to build quite a number of Bulant Clubmans and Bulanti coupes, had found his way to Adelaide and walked into the Edwardstown factory looking for a job. He'd been there a little while when he was approached about a job that had to be done on (I think) the Andy Brown Clisby-engined car.
"I see you're good with the arc welder, Brian, can you have a look at this little job?"
He was shown a crack or flaw inside the monocoque, you know what I mean, James, in where the fuel lives. He responded that he could do that all right and everything was put in place to get the job done.
Brian set the ampherage, fitted up an appropriate electrode, donned his mask and got into a position where he could comfortably reach in and get the job welded. And so he welded it up.
Taking off his mask, he turned to ask, "Is that all right?"
There was nobody there! They'd all bolted outside the door while he'd done it...
