Well, this is a new one on me. Probably not to a mechanic . I assume the aluminum part of the quill has welded itself to the steerer as the old headset wasn't sealed. So now what? Will the amonia trick that is said to work on seat posts work here? Do I lop off the stem and star drilling. I was thinking of turning it upside down and taking a rod through the fork and hammering out the quill that way... but not if its going to destroy the steerer tube. Anyone have a trick for this one?
