Building a 120 TO 127 Film Slitter Using Lego

A tutorial explaining how to make a homemade film slitter in order to cut and rewind some 120 film on a 127 spool. It takes just five minutes and uses easily materials that can be easily found at home.

Unfortunately 127 film format is almost impossible to find nowadays even if cameras of some interest such as the Yashica 44, the “Baby Rollei” or the Kodak Brownie still use this type of film.

Given that 127 film is identical to the 120 film (which instead is still commonly produced and sold) being only shorter, some people cut 120 film in different ways and then rewind it on a 127 format spool. In this short tutorial I will show you how to make your own film slitter using easily found materials at home in as fast as 5 minutes.

You will need:

  • 2 Lego bricks 20 mm height
  • 2 Lego bricks 10 mm height
  • A piece of cutter blade

Assemble the Lego bricks by putting the two 20mm pieces together in the center. Attach one halfway raised (as this will serve as film rail while cutting) using a 10mm piece.

Cut out a piece of blade with forceps and place it within the external thick brick and the latter thin one, taking care to tilt it a bit.

Place the last short brick to stop the blade in position and film slitter is ready.

To avoid exposing the film, do the process inside a darkroom or using a changing bag. The film can now be cut and then rewound on a 127 spool at hand. Be careful to push the film against the rail and press it well while cutting in order to make film rewinding easier.

There you go, quick and easy way to cut your 120 film into 127 format and you got to use Lego bricks! Yay!

    This is awesome. May want to use another lego horizontal on top of the film to keep the pressure even against the blade as well as serve as a finger guard.
