Unspooling 400' cores down to 100' daylight load spools

[Erik J Lindahl]

I've been doing this with a pair of rewinds in a calumet film changing tent, but I've been spooling a-minima loads down to 100' daylight spools. You have to half twist the film because a-minima loads are emulsion side side out, kind of a pain but free film is free film. As for an apparatus to spool down 400' loads I was thinking of using my arri 16s mag to do it. Then you also get the use of the footage counter on the mag. You can probably just get a 16s mag with torque motor and alligator clip a battery to the leads. Just an idea.
