And yes, that stuff probably could be in another thread, so to get back on track - it looks like a CIM powers your helix - what gearing did you use to power the helix drive, and what material was used for the central spire? |
Parker's not scared of work...
The spinner rotates at about 450 RPM. This speed was unscientifically determined during our prototyping.
The spinner is a 9-sided (
yep, couldn't resist) drum made of 3 pieces of 063 Lexan. Onto that lexan is riveted some brush assemblies.
We originally had Lexan fingers sticking off, but during our 3 weeks of testing and tuning we learned that sometimes the fingers can tangle with these silly game objects. We figured, "even if it jams 1 time in 1000, why risk it?" and went to brushes.
Any other questions?
