Re: Frozen Sail Slide
Looking up thermal expansion coefficient suggests that aluminum will expand slightly more than bronze when heated. However, that might mean the aluminum expands into the bronze on the slide, while the bronze expands out to the aluminum and holds it more firmly. Admittedly, I would still try it.
Another thought is to get some get some mild acid in there to start eating away at the likely corrosion that is causing this problem. Maybe Lime Away or even straight vinegar. The trick is going to be keeping it on the part while it works. Vinegar will dissolve metal entirely, so it really could work, if you get it in there.
Edit: diluted vinegar would eat corrosion off dive parts in 15-30 mins. This may take longer, but I would get hours, not days.

In the harsh marine environment, something is always in need of repair. Margaritas fix everything.
