Re: Cirkut Test

[Robert Erickson <cirkut8@xxxxxxxxx>]

I usually use 220 film to test my Cirkut cameras
exposure. 120/220 adaptors are a snap to make with a
couple of empty 120/220 spools and a couple of short
lengths of 1/4 inch threaded stock. (I usually simply
cut off the heads of screws) The two empty spools are
then held to the 220 film spool by screwing them
together.

I have several times used 35mm film to make Cirkut
tests, too. I simply taped the 36 exp. 35mm cassette
to a #10 spool. Then pull out some film and attach it
to the duum. You will need to find a dark place or use
a changing bag to roll the film back into the
cassette.
