This is NUTS!!!
I can say, in all the years I've been messing around with vacuums, I have literally destroyed one vac in my time, deliberatly! It was a dirt devil, swivel glide. Somebody had givin it to me, and I was going to fix it and "donate" it to somebody without a working vac. I worked on for 3 days, trying to keep it from throwing a belt, without success. I was so livid at the time I had wasted, I decided to completely destroy it on the way to the garbage can! I did this as rationally as you would go to work. I ENJOYED doing this! I am a 41 year old, mature, college educated person, and I destroyed a vacuum! I did this partially because I was so infuriated with the "junk" I had been working with, and partly because I didn't want some poor slob to find a nice looking vacuum and waste his time on it as I did. And the bottom line is, under the same circumstances, I WOULD DO IT AGAIN!!!!(and, most likely, ENJOY IT!!)
