Self-spooling Tray (toneCarrier 120)

The Tone dslr scanning system is a hit with me. The design is brilliant! The silicone wheels are slightly offset to pull the film flat across it's width, and the double "S" path uses the film's own plastic memory of curling towards the emulsion to provide the tension lengthwise to flatten the film longitudinally. I paired it with an old laptop that I installed MX Linux and Entangle to monitor the negatives as I turn the advancement dials. Finally, I can get perfectly centered shots showing the rebate, and while sitting down. Loading could not possibly be simpler - just push the film in until it hits the wheels, and advance by turning the knob counter clockwise. I purchased both the 120 kit, and the 35mm kit (that is why there are so many chimneys in the photos). I've done a bunch of scans with both - 6x7cm to half frame 35mm. No jams, easy operation, and it is fast. Excellent design and engineering.

Damaged multiple negatives. They keep getting stuck/jammed inside.

Good idea, some flaws in execution

I love this concept, the equivalent 35mm works flawlessly. Unfortunately with the 120, the film rarely stays within the guides. This means it often gets stuck. I use mine with the top open and guide the film by hand.
