Last year we had a chain driving our shooter. Our lead mentor was testing it and the chain broke and hit him. There was no damage to the chain :rolleyes:
We later went to a belt to drive the shooter.
Granted, foam is safer than rivets, but still…
Yep. It is all relative. NASA has one less shuttle due to a bit of foam that didn’t stay put.
This year’s prototyping scares me. Not as much as the propellors in '09 that teams were demonstrating running directly off a CIM shaft or wobbly bit of chain – with no speed controllers in the loop, just powered 100% off the battery.
But please please think about the shooter wheel as a rotating hazard. Also be careful of long hair, loose clothing, hoodie strings, etc.

It would be great if everyone put some kind of guard over their test flywheels. That’s not going to happen, but we can dream, can’t we?
(No, we didn’t guard our flywheel when we tested shooting either.)
This thread is full of eeeeeeeeeeewww.
But I guess shock value is what it takes these days.
