Well its all relative isn't it, maybe that's part of his bucket list. If he's in the business, then he has some "do me a favor" resources, but he could easily have $60'000 invested in it.

If you watch the other video, "Model V10 Engine Build compilation"... that's his son narrating for his father trying to explain each process in the still images, obviously he hasn't got a clue what hes looking at, but he wanted to document his fathers work. He mentions his father lost a few of his fingers while machine the crankshaft for that engine. That's a little too much invested for my liking, nothing is worth loosing ones dexterity over, and with his skill set you would think safety first and foremost.
