Can't get the drive side bottom bracket cup out I have an older Raleigh frame that I converted to a fixed gear and the bottom bracket cup on the drive side has been painted over a few times and I can't get it out. 

This is the type of cup (the one on the top left):



I've tried brute force (lost some skin on my knuckles) and it didn't even budge. Does anybody have any tips to get it out?
The drive side on most bottom brackets is reverse threaded. That means you have to turn it clockwise to loosen it.  If you don't care about destroying it, and are just going to replace it anyway, you can try this trick that I found, which seems like it would allow you to get a lot more leverage.
