Hi!

Do UK mechanical engineering terms such as clevit pins or Woodruff keys
or
Jacob's chucks mean anything stateside?
I think you mean clevis pins. Dunno about Woodruff keys, although I think
I've heard that term here in the US.

As far as Jacobs chucks, here in the US those are pretty much the standard
drill chuck on the end of an electric or portable drill. I don't think
I've
ever seen another kind, apart from a very few unmarked ones.

yes, sloppy fingers, Clevis pins

Woodruff keys lock gears/pulleys etc to large shafts, similar to roll pins
(same USA term ?) locate small pulleys etc to small shafts

Same name, as far as I can tell, although I might have been reading Brit
manual. At least I knew immediately what it was when mentioned.
'Jacobs chuck' as a term is not in common usage, but again, I knew what
it was. Mostly just referred to as a 'chuck' or 'drill chuck'. Clevis
pin is a common term, especially amongst us old farm boys.

Any Haynes auto repair manual has a pretty comprehensive cross-reference
of Brit vs. American mechanical terms.
