Any ideas on how to able to use the crankset? Can I 'borrow' the bb cups (if they're french threaded) from the red PH8 frame and find a spindle and bearings to fit?

2)&3) Yes, you can the BB cups from another French-threaded bike in your UO-8. The bearing size (1/4") is standard, regardless of threading. The spindle is the thing that you will have to figure out. French cups are typically thin walled, so a normal British spindle, or one with a "3" prefix, will have the bearing shoulders too far apart. What you can do is use a "5" series spindle, typically found in Italian bikes with a wider (70mm) bottom bracket shell, or another French one (TA, Stronglight etc.) which have the shoulders further apart. They are getting harder to find though, so be prepared to do some scouring of used bike shops, other forum members, online etc. The other option is to get one of the great Edco French-threaded cartridge bottom brackets that Velo Orange sells. Be warned though, they are pricey!
