(Liquid wrench doesn't work). Some people recommend alternately heating and cooling. <br /><br />I have used liquid nitrogen to help free a frozen Al stem in a steel frame, the coefficient of expansion of Al and steel is significantly different. But in your case if the shell is Al and the cups steel, then you would need heat not cold.Nosmohttps://www.blogger.com/profile/18276735115398361316noreply@blogger.comtag:blogger.com,1999:blog-9959776.post-55153509678087478882010-05-05T10:58:19.816+01:002010-05-05T10:58:19.816+01:00Yes, a fixed vice would be nice.

Worked for me with a stuck phil wood BB, though the cup did not survive the experience.Joehttps://www.blogger.com/profile/02607080600503061543noreply@blogger.com
