RASSOR COMET

The drum submitted is 170 mm wide and 450 mm in diameter, allowing two drums to be positioned side by side with mirrored and staggered placement. Its rigid design enables the use of thinner gauge material. However, the main issue arises when the drums fill up with stones, as they are pushed in but cannot be forced out. This problem is addressed through a design that separates stone sizes based on inner drum gaps, allowing sand to pass through while keeping larger materials contained. Each drum weighs 2.2 kg, leaving room for end caps, although these were not included due to their standard appearance. The image placement was strategically optimized to maximize digging efficiency with minimal force required.
