The process was actually easy and I am very impressed with the precision engineering of the cutter and mounts.
All you have to do is load your uncut strip of 35mm film into the cutter by aligning the first pair of frames with the cutting holes. Then use the knob to move the film from shot to shot, it clicks nicely into place for each image.
Push down on the cutter and it stamps out the stereo pair of images you are currently looking at. Take the resulting finger nail-sized film clips, slip them into the tweezers-like inserter, then slide them into open slots in the blank reel.
The only challenge is making sure you have the right side of the reel facing towards you (the one without blank labeling lines for each image) as you insert the film. You also have to insert the film backwards as if you were looking through it from the opposite direction.
I goofed this up a couple times before I paid good attention to the circle and square guide marks put on both the film and reel. I will post about this process in more details soon.
Putting my first reel together only took about ten minutes, and I bet with just a little practice it will easily get under five.
