you guys might have some luck freeing them up by putting them on a hot plate or in an oven... (in front of your heater in the winter)

copper expands slower than aluminum, so it had the potential to fall out on its own.

other method might be putting it in the freezer, after it has stabilized, pull it out and let it sit, the aluminum should return to room temp faster, making it a looser fit. I can push this one back and forth about .050" at room temp with my hands.

work smart not hard. I'm going to see if I can figure something out to do with it.
Yay, differential thermal expansion. I was thinking about that too. Aluminum's coeff of expansion is almost 1.4 x that of copper.
I've been playing with thermal expansion at work a lot lately... can't say it isn't fun, but I feel like I should have better luck with a cardboard box understanding what I'm talking about
