Here are the proper tools for those type of bottom bracketsPark Tool Co. » HCW-4 : Crank and Bottom Bracket Wrench : Crank ToolsPark Tool Co. » HCW-11 : Adjustable Cup Wrench : Bottom BracketThey pretty much suck getting off without the tools, but the tools cost more than the bottom bracket is worth.
Thanks Whisperer. I tried the vice with no luck at all. I do seem to need a new bracket though as the crankset rocks back and forth a bit. Maybe with some luck I"ll only need to repack the bearings. I"ll still need the tools though.
Did you take the lockring off already? Those are adjustable, similar to looseball hubs. As long as the bearings and cones are in decent shape, you can repack and adjust those BB"s.
I was able to get the lockring off quite easily. It would typically be over the threads in that second picture.

Be warned, you can"t budge the fixed cup with just the proper wrench. You will need to use the vise (strip the frame of everything but the seat/headset/maybe deraillers) and make sure that it is seated in the vise squarely and securely. As long as the frame has English threading, turn the frame to the right in the vise jaws.Your other option is to get a couple of large washers, nuts, and a good strong bolt. You will need a deep socket or an extension to set this up. First, place a nut on the end of the bolt, and stack a washer on top of that (it must be big enough to not fit through the bottom bracket cup, but the bolt needs to pass through). Attach either your adjustable wrench or the park cup wrench to the outside of the cup, followed by the second washer, then the nut. Get everything nice and finger tight, then get your deep socket and a wrench and tighten down your nut/bolt/washer assembly. Tight.Now, you are free to start attempting to remove the fixed cup, just be careful, and wear some hand/knuckle/finger protection. Since your assembly is tightened to the cup, you may use a rubber mallet to "persuade" the cup to loosen up.
