.....The new tube can be inserted into the hole
without a press fit, but it does not rattle around. This is not a tight
enough fit. It has to be a press fit. I am hoping there is a tool to
reduce the inner diameter of the aluminum hole so that the new tube is a
tighter fit.

Why not expand the tube? Can you fit a #6 cap inside the tube?

Hi. The new tube is steel, and the piece with the hole is aluminum, so I
thought it would be easier to make the hole smaller. Sorry to be ignorant,
but I have no clue what a #6 cap is. The tubes are about 30mm or so in
diameter. The inner diamater is around 10mm or so. I'll have to check that
and report back.

A #6 cap is the fuse activated detonator for commercial dynamite. They
are about 8mm in diameter and the shock wave should expand the tube.
10mm wall thickness is a lot, you might have to use more than one.
OTOH, when you get the right charge the tube will be swaged in real
tight.
