[Steam-engine] Pouring Crank bearings.

[James Mackessy]

Hi Andy!
     While all of the things you mention are valid concerns,  the real
learning starts when you
just pour the babbitt. You are right in stating that these were simple
machines, and if you
take reasonable care in getting the position close, things will come out ok.
Many old engines
are out there running with things way out of whack due to wear, and they
seem to do fine.
If it doesn't come out right, melt it out and do it again. It's not like
it's cut in bronze;-). I don't
know what the original location tolerances were, but I bet we'd find it's
not as close as we thought.
Best Regards;
