The guy has paradoxically also a very pragmatic approach on acceptable tolerances which could be found offensive by some people.

Warning to sensitive persons: -As this video is just a shop tour, not a single frame of how-to machining is included,
which might be perceived as tedious by most, but perhaps a bit thought- and action-inspiring for the happy few of us easily entertained?
Not all of us are within physical or financial means of scoring at Craigslist, so we just have to grind our own to achievable tolerances.

Thus, you've been warned.

Ah, yes - a new, EMD 567 wrist pin is app 72 mm dia, 163 mm tall and micropolished to 2 µin RA.

Quite an interesting guy I would have loved to have known about that 16" rotary table he had for sale I used to have an ultra low profile 14" that cost me many, many times more than the price he was selling that one for
