Brief Description: Counter sink/debur water pipe counter wieghts
Thanks to my friend Cliff's imagination and access to his machine shop I was able to use a mill to counter sink the water pipes. He also created a tool(see picts) out of a piece of flexible plastic long stock with a grove cut into the end to hold a 1inch wide x 5 inch long strip of sand paper. We chucked the long stock, wound the paper and ran it through the inside of the pipe to debur the holes.
