great, Frederick: with respect to the frozen Cinelli stem, here's what I would do. I'm assuming that you have an aluminum Cinelli 1A or later, eh? These are available, and not expensive if you want a "rider" condition as opposed to NOS.
I'd drill out the head of the binder bolt stem. A 9/32" drill will eat out all the meat, and needs to go in exactly 7 mm, judging from the one I just checked (later 6 mm head, not the early 7mm). Once you have done that, a center punch attacking through the center of the drill hole should punch out the expander cone. If you're lucky, you didn't tear up the stem, either, and now have the simpler problem of freeing the stem from the steerer tube.

(I haven't actually had to do this, but it seems safer than cutting out a section of the quill to free the binder, and then having no purchase to work on removing the stem.)
