I had to remove a total swine of a BB this week. It was a nice square taper Campagnolo sealed BB with the six semi-circular cut-outs. It says "Lock 70Nm" and our matching Park Tool spanner is only about 8" long, and my biceps failed me when I tried to undo it. I locked the tool in the vice but the frame kept jumping out when pushed, so I clamped the tool onto the BB using a QR skewer through the BB spindle. It still took such force that a mate had to hold the bench still while I torqued the frame round, but we got it out.
