They say “you learn something new every day” or “ you never stop learning” (although some seem to never learn anything at all.

Yes, I did see that one. Thought it might be quicker with the two vices, rather than making up two of those screw jacks.
The trouble I had was, setting up the Y axis changed the X, and vice versa. Also, I haven’t got a height gauge like him, so I had to wind the table back and forth millions of times.

Had mine blow twice, then got it refaced then I dewebbed it and it was fine for years until I sold the car, always thought a 5 pot one piece manifold was idiotic.
Problem is if you make any exhaust manifold more than one piece, any joints will end up leaking.
Older blokes at my place of work told me a decade or more ago about castings being left in or close to the the gents to speed things up.
We used to have our own foundry (before my time) so the older guys would use castings where you or I would go for a fabrication - our pattern shop is still going though.
I have heard BMW used to source used production blocks that had done a good few miles as material for the highly strung turbo race engines - all the movement had been done by all the heat cycles in use. They still only lasted a lap or two on full welly - but that was enough.

I know it isn't pretty as I were really in a hurry
Throw it under the bench until you need it again...
I've heard BMW cast F1 blocks back in the day were left outside for seasoning for a year with people peeing on them (probably an old wives tale?).
Cast manifolds sounds like a good idea to remove after 10,000 miles heat cycling then remove an surface grind again.

How does peeing on them help ?
Or is it just a fetish thing ?

Engine Myth: Urinating on Cylinder Block Improves Durability - EngineLabs
There's an old legend about BMW Formula 1 engineers urinating on cylinder blocks to help "season" the iron casting before race prepping. The survived 1,500 horsepower, so did the trick work? Check out the story!
