 Last year we saved a ton of money by using a good bit of square tubing for the frame of our robot, square tubing is a lot cheaper then C channel. We get to use so much raw material that the cost should go down in certain places. - Derrick Maust [more] |

I see we can expect a sick shooter from G-House. Any pics or vids of the final robot? Hope its powdercoated yellow again! 
See you guys at Trenton next weekend.

How do you put a drill bit in backwards?!?!?!
That seems pretty crazy to me, maybe its because i'm a machinest.

Was that shooter designed by a pirate? I see he signed it.

I hope he knows that you can break certain bits by putting them in backwards. Mainly smaller wood bits, but it can happen. You get the same thing when you put a small bit in the chuck pretty far. It kind of shatters.

This guy Rick kept putting jigsaw blades in backwards- one time he actually tied to cut with it before anyone caught it.

He is also using the power to tighten the chuck which is not the best of ideas...

There are several people in my group who don't always where safety glasses.
I am trying to change that.

yeah, I'm loading a few now, also if you go to popular mechanics website, they did a story on us
http://www.popularmechanics.com/scie...s/4304081.html
to address the safety glasses, they are on his head, its a hint of yellow cause we own DeWalt glasses, but you are right, glasses don't work when your wearing them on your head and sorry we don't powder coat, its a simple built it, we like it, take it apart prime and paint it with Krylon.(Sun Burst Yellow) and no NJ regional for us : ( we cant afford more that one, we will be in NY Javits Center WAHOOOO!!!!

Of course, they're also meant to be tightened on the shank, not the flutes. Doing it this way dramatically increases the danger.

I am allowed to yell at everyone cutting drilling ect. without saftey glasses on. I have been told it is one of my jobs, along with memorizing 90% of the rules and working on building the robot

Maybe he knows the only safe way to drill without glasses, is to put the sharp end of the bit in the chuck?

WARNING: Do not attempt to tighten drill bits (or any other accessory) by gripping the front part of the chuck and turning the tool on. Damage to the chuck and personal injury may result. Always lock off trigger switch when changing accessories. |

For two, whenever I see my students not wearing safety glasses while using tools, I tell them to put them on. Practice makes perfect; you get the students wearing safety glasses enough and they'll start doing it on their own by instinct. Forgetting to wear them just one time could mean you'll end up missing an eye. I don't know about you, but I don't enjoy metal / lexan shavings in my eyes - it hurts.
If just one person remembers to put on their safety glasses from this thread, then I'd say someone has learned something. Safety should be preached over and over again, it's not something to take lightly and I think your post pretty much has proven to me that I wouldn't want my students working around your unguarded machinery. Common sense is no substitute for good practice.

.Fixing bad measurements is an important skill, and one I think FIRST (or pretty much building anything complex like a robot) does very well.
On a side note, I think he will have a hard time keeping the drill on the mark with that drill bit in backwards. I can pictures the drill traveling all over the place in my head, makes for a funny little thought too.
On another side note: how does one make that mistake more than a couple times? Even once is a stretch, but you'd think you'd learn.

My apologies Ryan my main beef was with the absurdity of attacking the way he was tightening the chuck. I'm guilty of hi-jacking the thread to spout about 6 weeks or more of pent up frustration with some of these ridiculous posts, not just about safety and I kind of lost it. I also know that there have been far more absurd posts. I know that common sense is no substitute and I agree that practice makes perfect. I've had to be better about wearing my safety glasses and I assure you my house is safe (all my family still has their fingers). What I failed to acknowledge was how dramatically the "art" of safety shifts from when I'm in my basement, alone, to when you're in a room with 20 or more high school kids of all different skill levels using multiple pieces of equipment. As proof of how much robotics has influence me, I used one of our table saws to make a shelf earlier this week and I felt, almost naked, without any safety glasses. In fact I intend to buy some to keep around the basement now that the season is over. I apologize for sounding rather ignorant and crass. I know better.
