You can turn a 120 film into a ready to use 620 film with a pair of flush faced side cutters and sandpaper. Sand each end of the 120 film spool down to about half it's thickness, then nibble around the ends of the spool until flush with the surface of the film . If you get into a routine you can do a few in half an hour and without disturbing the film on the roll.
