Our lift system for the arm worked beautifully, but we soon realized that we had not allowed enough room in the upper portion of the tower for the arm, which ultimately resulted in the tower and axle getting warped. As our arm had screws and brushing on it, it was
actually wider than the gap provided by the two support channels,
making them bend apart and bend our axle. We began brainstorming on
methods of preventing this, such as supporting the channels to prevent
bending or moving each channel a spot over. We finally decided on using
two supports connected to a single support with flat brackets in the
middle, which provided a sufficient enough space to allow the arm full
rotation without any bending. At the same time we edited the lift system and moved the spool outward to allow for easier access and maintenance. The result is the Finger Muncher Mk. II – a beautifully efficient arm and lift system that will happily devour any finger that gets a little too close to it.
