The physics of machinery is often underestimated. When I bought a canoe years ago, and the shop owner was showing me how to tether it to the roof of my car, he told me to always be careful to tie up the lines so they could not possibly get under the car and into the axles or it might wind up the line and actually crush the roof down on top of the car body. 'Sounded exaggerated, but I figured he wouldn't have made up such a story while selling canoes, so fair warning. Likewise with a buffing wheel. The energy available is beyond the rather delicate work you might be doing. Impressive. Thanks for posting. Buffing wheels are important tools, but for the regular pipe smoker, a rag and some elbow grease is probably sufficient. I resist the idea of keeping pipes looking new. I want a little wear to show, along with diligent upkeep. If people visualized the physics at hand, fewer would drive cars or other vehicles, and no one would exceed the speed limits except maybe on the vast reaches of Texas.
