Thanks guys. As always, you've been extremely helpful (and quick!).
I raced down to their shop an hour before they closed for the weekend with the sole purpose of buying several tools and the BMX freewheel, because I wanted to get started on this thing tomorrow morning (my day off). I guess I'll order everything online now, and I won't be able to start for at least a week...
*sigh* Their loss, and my loss, too.
Thanks again.
