My frame is steel and I have a 1" diameter Cinelli quill stem - the older long bolt and wedge type, which seems to have become part of the inner steerer. The wedge and screw have come out no problem, but the stem is badly stuck even after a 1" thick stick was placed up under the belly hole of the fork and hit with a large steel hammer, all of this after 3 days of wd40 saturation.

I have taken it to the LBS who could'nt free it manually but hinted that larger cycle repair stores have a special 'machine' to push out nuiscence stems. Is this so?

If not..any other methods folks?
