Today, I was drilling a 1/4" pilot hole in a 1/2" plate. Going to drill a
1/2" final hole. The plate was about 6 x 9". I did not clamp it to the
base. The drill caught the plate and began spinning it. I just jumped
back. The more it spun, the more it became out of balance, and it finally
snapped before I could reach in and hit the switch. It went flying, but
didn't do any damage. Broken drill bit was all.
Accidents happen when we are doing the most mundane common tasks, and do not
observe the MOST COMMON safety precautions.
DOH!

Thanks for the reminder. We've all done similar things - or worse.

You are a very lucky man.
I did not have an accident today, but easily could have. I was lifting
a heavy welding machine with my truck crane. The truck was on an
incline.
As I lifted the machine, the crane started swiveling spontaneously so
that the welder machine turned into the lower direction.
Since this happened when it was an inch off the ground, I was able to
easily lower it and stop the turning. But, if that happened when it
was high above, my truck would be punished for my own negligence.

Being an experienced crane operator, I can sympathize with your situation.
Just a gentle reminder for next time to level up before hoisting. Level
will always find level and plumb will always find plumb no matter what the
plans or drawings say. Glad you got off light.

I sent off an e-mail trying to get some permanent clamps installed on
our prototype shop drill presses earlier today, BEFORE reading your
post. Your post will get quoted in the follow up e-mails.
For the record, I am firmly in favor of the 'Vice Grip' single sided
clamps with the mounting bolt permanently fixed to the table. Just
adjust the height screw, quick squeeze, and your part is clamped down to
avoid both spinning and lifting when it goes through the back side.
