I have a story that relates here. It is pretty embarrising actually. I was moving an unrestored erie clock face pump across the garage floor one day (a couple years ago) to get it out of my way. I was using the "walking" technique and made about ten feet of progress. I was pretty close to the far wall when I tilted it up a little too far and it fell into the wall. The light shade above the face made a perfect puncture right in the dry wall. So here is my pump leaning at a 45 degree angle imbeded in the dry wall, all of a sudden the bottom starts to slide out and the whole pump goes crashing to the floor. It sounded like a 10 car pileup, with multiple people yelling obsecenities. Luckily, I was able to jump out of the way and avoided getting trapped under this death machine. The impact with the floor cracked the light shade into 3 pieces and shattered the window face, in addition to the damage to the wall. So there I sat with a busted wall, a busted pump, and a busted pride...talk about a grown man crying. I didn't touch that pump for a year after that. Everytime I would go in the garage after that day it was like the evil pump demons possessed this pump. Right now it is in about 30 pieces being blasted.
