I bought a spanner. . . and wouldn't you know that the fixed, drive side cup is beyond mere mortals? I do have the proper wrench for that, at least, but can't move it. Not at all. Not at all.
No, I don't have bench vise.
After the 5K tomorrow, I'll give it a ride to ye olde shop and they'll get it off, I'll be riding again by tomorrow evening. to be sure.
