I had gotten 3 21' lengths of 3/8" in a delivery pipe / fitting mess up. The JR college had one in the sand casting shop so I made a bunch and gave them a length of pipe. I was handing them out to buddies for Xmas presents one year, most of mine need to be melted and recast, it will take a day or two to find the all.... as bad as drill bits!
