This loading base can be used to load a standard 70mm spool/cassette from any bulk roll of film.  It also accepts Mercury 65mm spools, for a universal solution.  It is designed to be exceptionally easy to use in the dark (it does require darkness).  Two takeup-side adapters are included so you can load directly to a spool (recommended) or onto a spool inside a cassette.A set of feed-side adapters are included to accept standard Kodak spools as well as film that comes on less-common cores, as well as bulk film with no core.  It is thus compatible with every type of 70mm film we've encountered.A comfortable rotating winder handle allows you to easily and rapidly spool as much film as you wish.  Acrylic bases and brass rods ensure friction-free spooling.This Bulk Loader is a significant improvement over the Alden 70mm Daylight Loader, our previous solution, and all others we've seen.
