Sheldon's Nut-and-Bolt tool has never worked for me, actually. I sheared one bolt - then I bought a special super duper tough hi-tensile bolt... it just kept tightening and tightening and tightening until eventually, even with my housemate on one side and me jumping up and down on my 3ft breaker-bar, we gave up.
The nut and bolt still comes in useful when bolting the proper* removal tools to BB cups, though.
I say proper... what I mean is tools made from old steel stock that I turned up on a lathe. They work fine.
