The bottom bracket cup from HELL! (removal help)
Edit: Solved, thanks hueyhoolihan.
Hi all,
I'm having a hell of a time with this one fixed BB cup.
I think it's a cheapo Schwinn bike. The removable cup on the left loosens counter-clockwise, so that means British threading and the fixed should remove clockwise, correct? And in a vise I should move the bike counter-clockwise?
Well I've tried everything I can think of. I tried the Sheldon Brown tool a few times with a giant bolt, all it did was bend the washers (I marked the BB cup with a felt to confirm it wasn't moving). I then tried the vise method turning the bike counter-clockwise and all this did was snap the cup from the vise leading to chips on the BB.... not enough surface to grip properly.
This is a homebuilt recumbent so it's a little awkward to manoeuvre. I'd just say screw it and use the cup but I wanted a much closer chainline and I don't have a short enough axle.

Huh, that's interesting. If I've been turning this dang thing the wrong way the whole time I will eat the bearings. I can't get my head around this, any advice? Unfortunately there are no markings on the BB cups so I have no idea what it is.

Oh my god I'm such an idiot. Ok I did the vise thing again turning the gaint-assed bike clockwise instead and it came loose. Thanks for getting me to rethink this.
