I had once made a funny-looking assembly consisting of a rolling car attached to a rod of slotted aluminum chassis by a spring. I then tried to drill a hole in the car without clamping anything down. After I inevitably lost my grip, the part climbed up the drill press, spun around a few times, then was ejected forcefully into the floor, compressing the spring and causing it to hop 12' across the shop. Fortunately no one was in the area when this occurred - both for their safety, and for my dignity.

They had drilled the first 3 and most of the 4th with the drill running backwards. Quite amusing! In addition, these were the 4X4's that were cut 6" short and we had to add 6".

The first time I drilled a hole in the piece of polycarbonate, I had the drill running backwards. It took about sixty seconds to get through 1/8" of plastic. I remember thinking out loud, "man this stuff is tough!," when in reality I wasn't drilling through the material: I was melting through it.
