Yes I know about the boiling and different rates of thermal expansion and that delrin is safe to boil. I switched it on to get it heated up, and figured that would be enough. I just wanted everything apart when I started to boil it. I guess I'm just OCD that way. The middle delrin piece was no problem, it was just the bottom.
Anyway, the point of my post was just for the Revolution. I agree that if the Revolution came with a delrin sleeve, there would be no real advantage to removing it, but it doesn't come with a sleeve. You only get a sleeve if you get the TV1 and buy the Revolution adapter as an add-on.
