The vise thing works, but try the above pictured bolt first. (Actually, I just got a normal metric bolt from the hardware store to do the same thing.) It will solve a lot of problems.

If that does not work, try Sheldon's trick. He described it somewhere in his pages. It is a strong bolt and stack of washers and a nut. As it cranks down on the face of the BB, it puts a ton of torque on it and that baby will move.
