In over my head?
I have been carefully picking away at rebuilding a 1960's (approx) CCM encore mixte. It's my first ever project bike and I have been lurking heavily on the forums, but I just ran into a problem that anyone with more experience would have seen coming.
The bottom bracket is.... not working right. There is a spot where as I peddle, it grinds.
I am not trying to do a restore here. I like the way the frame fits and I want to use this bike as my main commuter. To me (and please let me know if this is wrong) the thing to do is replace the bottom bracket and crank set with something modern and easier to service.
Here's my questions: How do I dismantle the current bottom bracket? (there must be an online tutorial somewhere and I just can't find it) How do I know what parts to order?
Thanks

Remove in order:
Dust caps
Nuts/bolts
Insert crank removal tool and remove arms
left side lock ring
left side adjustable cup
spindle
Before you do that drop the chain from the chainrings and check that the chainrings aren't hitting the frame. If the cranks spins without hitting anything then your problem is internal.

1) Remove cranks. If cottered, take care in pounding out the pins, so that they may be reused. If cotterless, get the correct extraction tool. (See disasters thread in this same forum.)
2) Unscrew lockring on left cup (anticlockwise).
3) Unscrew left cup (anticlockwise).
4) Pull out spindle for cleaning, inspection, and replacement if pitted.
5) Inspect and clean both cups, generally leaving the right side in place, unless it has to be replaced.
6) Put in new balls (11 1/4" per side) and grease.
7) Adjust so that spindle turns freely but does not rock appreciably.

Picks would be helpful as we have no idea what type of BB it is.

Perhaps a visit to MY "TEN SPEEDS" and a few moments reading How To Rebuild a Bottom Bracket will help.

Thanks!
It's the old cotter type. I think this may be the point where I have to bite the bullet and pay someone to do it.

no shame in that - you dont have to wrench everything yourself - my advice would be to ask the mechanic if he / she minded if you watched so you could learn - i have done this at my LBS and they are cool with that - but my goal has been to essentially eliminate the LBS for repair and maintenance - you'll save some dough (although tooling up has its front loaded costs) but it's quite satisfying when you can wrench your own bikes - good luck - btw - enjoy the mixte
