So is this tool worth it?



I've tried the Sheldon tool without much luck. Perhaps I am not giving the PB blaster enough
time.

One think I've learn is you need to use harded washers. The ones pictured were flat
before I started.

I won't even picture the bottom bracket. Shimano. Didn't pay enough attention to the placement
of the washers and total busted the thin center section. Tried hacksaw on the cup and a standard
one makes no progress at all. I guess the thick part is hard steel.
