just a reminder to remove everything expensive and fragile around ball shooters

[Madison]

A CIM motor outputs 2.2 Nm of torque at stall -- a lathe can put out a bit more than that, no? It's the difference between getting hit by a baseball and a truck at 70 MPH.

i really don't see how this could be any less dangerous than any other attempt for a prototype, we were shooting towards the classroom half of the room, where the greatest danger are rulers and vices, which could of course hurt you, everything has potential to hurt you. don't be like those people who wear plastic gloves everywhere they go, sure it keeps then safe from germs, but it really isn't necessary.

and as cody c said, we're high school kids, dumb things can be expected from us.

Andrea, there are a number of reasons why what you did is unsafe. Starting with your lack of protective equipment, safety glasses. A lathe is not a good motor for this prototype because it did not provide proper support for the wheel and shaft. I think others could go ad nasuem about the other safety issues.

That video was posted as a joke. Not as a sincere warning to other teams. It was a "hehe, look at us, we're doing something that's dangerous!"

What I find most alarming is your attitide towards others on this forum. We're simply trying to help to help you keep it safe. We would like to see you graduate, not die. You have also shown disregard for the power of the equipment that you are using. "don't be like those people who wear plastic gloves everywhere they go," do you realize that lathe has the power to rip your arm off?

This thread should be closed before other students start thinking that following standard safety precautions is un-cool.

Though I doubt that anyone will start to think this, I agree. Thread closed.

I think we all understand that we need to be safe. Let's make it happen
