From time to time I work a little with two of my brothers, who are mechanics.
Got used to using large high speed angle grinder with a various brushes to clean off stuff. Tried the same with forged stuff, works fast but, always with the same results. Being pelted and many time injected with the flying mini wire knives as they left the wheel. Until I saw one of the Bill Epps dvds. I was an instant convert!!! Went to "HB Freight" and bought a VS Polisher, set it up and tested with different wire wheels, works great and life is good. (Thank you, Mr Epps!!)
A pain full side note to those little flying wire knives, as mentioned before, they stick in clothing and can be transfered to other clothing in the wash. Not just socks either, under ware can be a very rough place to find a stray piece of wire from a wire wheel!!!!!!!! hehehe Go ahead laugh, I think its funny now too...but when it first happened..... WOW!
