Dear Mike,

Scotch Magic tape should work without problems. I've used it for many years. I would remove any vestige of tape from the spools you get and using one piece of tape, start on one side of your new film, continue around the spool and finish on the other side of the film. I have used this for literally hundreds of rolls and never had one come loose.

Good luck with your future rolls, whatever method you choose.
