Foam Board Cutters

thingiverse

I crafted these tools to improve my cutting skills when building foam board planes. I designed the blade depth adjustable feature because occasionally you don't want to cut all the way through. There are 4 distinct cutters available. 1. Straight single blade cutter. 2. Double blade cutter. A 4 mm gap exists between blades, ideal for creating folds. Specifically, it's suitable for creating A folds and B folds, which are familiar concepts among Flite Test plane enthusiasts. 3. Edge cutter. It holds one blade and an edge guide for cutting 4 mm into the edges of the board. The same holder is used as with the double blade cutter, but instead of a blade, use the guide piece. 4. 45 Degree cutter. This is primarily used for control surface relief cuts. I am utilizing razor blades rather than utility blades. I'm holding everything together using 3M screws and nuts. Razor blades are extremely sharp. I make no claim that these make them safer to use. Proceed with caution, as you see fit.
