How to slit and roll 9.2mm film
Minox film is technically specified as 9.4mm wide. But for self loading, it is better to slit it slightly narrower to 9.2mm to prevent jamming the casette.
- Clean the MINOX slitter with a rubber blower to remove dust
- In daylight, put a 35mm film cartridge at one end of MINOX slitter, pull out the film lead, slide it into the film channel, passing it under the blades, tape it to the take up cylinder with a piece of 3M tape.
Slit film into 9.2mm strips
- Go to dark room ( or dark closet), push down the blade assembly with one hand, and crank the handle with another to pull the film through the cutting blades until the film stops. Do not rewind the slitted film strips back into the 35mm cartridge, as the strips can easily tangled and jam up.
- Hold the cut film strips tight on the cylinder with one hand, cut the film strips loose from the slitter, remove the take up spool with the slitted film strips on it, remove two perforation strips, discard them, save the cylinder with two long film strips tightly wound into a 35mm film canister for next step.
- Keep only the film canister with slitted 9.2mm film in the darkroom, remove the MINOX slitter from darkroom.
- In day light, get four empty Minox cassettes, open all caps of the four cassettes, put four supply side caps, four open casettes without caps and one crocodile clip( from Radio Shack) in an empty photo paper box( for example, Agfa RC paper box ) , another spare photo paper box and a pare of scissors; bring them to the darkroom.
Roll 9.2mm film
- In total darkness. Remove the cylinder with cut film strips out of canister, cut the films strips loose from the cylinder at very ends; now you have two long 9.2mm film strips, save them in a storage box.
- In total darkness. Take one piece of long film strip from the storage box, fold it up at two ends, hold these two ends with one hand, pull the film into a long U shape with thumb and index finger, let go the two free ends, you are now holding the middle point of the long film. Cut the film at that middle point to get two equal length short film strips, put them into the other empty storage box. Do the same with the remaining long strip in the storage box. Now you have four short strips of film, about 42 exposures each. With this " double up and cut in the middle " method, you do not need to measure film length in the dark.
- In total darkness. Put aside one opened film cassette, take out a piece of short strip from the storage can, hold one end with a alligator clip,
Radio Shack alligator clip makes an effective film winding tool
wind the film emulsion side inward into a roll; hold the rolled up film, remove the crocodile clip, slip the film roll into the take up side of Minox cassette, make sure to leave an one inch and a half lead outside;
- snap close the take up side cap.
- Repeat the same procedures with the remaining three short strips.
- Darkroom work now done, the remaining procedures is in day light.
Pack film into cassettes.
- In subdue light. Attach the film lead to a MINOX cassette 10mm spool, with a piece of 40mm x 6 mm Scotch tape (available from art shop ) make sure the film strip aligns with the film take up spool perfectly;
- Insert the take up spool into the take up side chamber of cassette, slide the film carefully into the cassette door, snap close the take up side chamber.
- In day light. With a one-hole punch, make a half moon shape cut out at on the film between the two chambers of cassette, to indicate unused film.
- In day light. Blow off any dust on the film with a rubber blower, store the film cassette into the cassette box. Do the same with the remaining three.
- Mark the film type on a stick on the cassette containers. Now you have four 42 exp 9.2mm film cassette, ready for use.

HOW TO AVOID FILM SCRATCHES DURING SLITTING. Since the Minox slitter is made of metal, it does not produce dust of its own, dust particles are external. Before use, blow the slitter bed with a rubber blower bulb, use a magnifier to check of any remaining dust particles then blow again util clean. There are replacement slitter blade assembly available from Minox GmbH. Blunt knife blades will produce film chips.

ECONOMY OF SLITTING FILM. Slitting your own film not only vaslty exppands your choice of film for Minox, but also lowers the cost dramatically. One roll of 35 exp Agfapan APX 25 is about $2, from which you can slit into four rolls of 40 exp Minox film, at a cost of only $0.50 each. As for the Minox casssettes, they are reusable. You can buy it from Minox Processing Lab, at 10 pieces for $10. If you think Minox slitter is expensive ( available at Minox Processing Lab ); you may find slitter kit sold at SUB CLUB SWAP MEET site.

Martin, you said there are replacement blade sets for the Minox slitter? Great news. I was told by Minoxlabs that they didn't offer them at the time I asked in September.
-- Tony Rowlett (firstname.lastname@example.org), December 30, 1998.
Tony, I got mine sliiter replacement blades about a year and a half ago, from Minox GmbH; I knew some others got them from MPL; may be they are out of stock at the moment. In Subclub website, SWAP MEET, jb007 has a for sale ad, in which he offered replacement slitters. His ad title "tones of MInox stuff".

Fuji Super HR comes in a variety of thicknesses. Only the thinnest stocks should be used in a Minox IMHO. Your film wasn't harder, it was thicker. The drag that occurred in your film splitter is the same drag that will occur as you pull thick stock through the fabric light traps of the cassette. And each time you advance 5mil thick stock (HR-21) through your Minox, you decrease the amount of time till the next trip to the repair shop. If you load 7mil stock (CF-100) you'll never be able to get off the first shot because your camera will make a sound like it bit a rock. Then jam tight. If this is what you have, you can still use it in a Minolta-16P, or GaMi-16.
Here are the safest stock numbers for Super HR/Minox: HR-38 16mmx65.5m(125 ft) thickness 2.5mils. HR-70 35mmx65.5m.........thickness 2.5mils.

When punching the marking hole at the end of slitted film, be very careful not to let the piece of film "chad" stick to the film, which may find its way into your camera.
