Default Shaft Log / Cutlass Bearing - tight fit...?

Don't heat the log, chill the cutless bearing. Pack it in dry ice, or a
dry ice/alcohol slush for a half hour or so and you'll find it slides
right in. It will expand, holding it in place as it was designed to do.



Supposing I worked the numbers correctly - that you would need
to heat the outer part by 500 degC plus - it is always possible to
produce the required difference the other way - by freezing the
inner part. Oh wait, there is no temperature in the universe that
is 500 degC cooler than ambient. Maybe not then.
