Getting BB cups in
« on: April 07, 2011, 08:23 PM »
I have the last few bits (just waiting on brake cables now) to add to my 85 to complete it, but the fooking BB cups will not go in!  :tickedoff: I've tried hitting with wood, rubber hammer etc.. I don't have a vice otherwise that may have been the first option. Anymore thoughts of how to get these buggers in!

Thanks,

Matt  ;)

Also could do with the same thing matey, I'll have one of your new fangled 'tools' if you have one.  Saves waking the neighbours with my hammering at 11pm

Don't know what you are building, but the internal BB shell is free of paint isn't it?

Take the frame and cups to an engineers place, get them to measure them and machine the cups down for a tight friction fit, not worth forcing them in, they will go, but what if they split the shell?, frame fooked.

might cost a tenner, but I would not want to get a big hammer anywhere near 1985 chrome of that value!!!

that was exactly what I was gonna say... some used but minty ones for example...

Old age should burn and rave at close of day;
Rage, rage against the dying of the light."

Well thats a given I'm afraid, they'll have to put up with that unless this tool has a muffler attached   :angel:
