How much needs to be taken off?

Put the two washers in a piece of threaded rod. A couple more washers,
that fit the ID of the tube, on the inside to locate the tube. Go easy
with a file, or even a piece of plumber's tape.

The chuck out of a burned up drill, sunk into a piece of hardwood, makes
a nice live center in a pinch.
