thanks!
I enjoyed this part:
I did a six-year apprenticeship with Alf Francis, who was Stirling Moss’s mechanic in the ’40s and ’50s. On my first day at Alf’s shop, there was a 275GTB that had dropped a valve, and I couldn’t wait to take the thing apart. I’d gone to engineering school; I thought I knew everything. Alf said, “Oh, no,” and instead of the GTB, he gave me an irregular piece of mild steel and a couple of files, and told me to file that chunk of metal into a cube without using a measuring device. He had me standing at a vise for two or three days to see if I had the patience to file that shit piece of metal.
