I have used that exact setup. The gentleman who owns it told me he would let me try it but to make sure I was ok with the pipe I wanted to learn being damaged. I told him I didn't understand, why would the buffer damage my pipe. He said that you will launch pipes like your on a pitching machine until you learn the right amount of pressure. He said this particular setup, while convenient and relatively inexpensive, is not ideal. YOU WILL LAUNCH PIPES!
So I said I would try it out on an old beater I had in the garage. Sure enough 30-45 seconds in and wham my pipe goes off the back wall and skitters across the floor. Didn't break it but did put a nice deep cut on it. I think I launched that pipe 3 more times. I did watch him buff a pipe and he didn't have any problems. His pipe came out beautifully. He said that he still launches one every now and again but just hopes it isn't a customers pipe.
Be careful with that one on nice pipes!
