pastorbobnlnh suggested I post this up. I made a chain whip yesterday from a $1.50 thrift store BBQ fork. I separated the necessary pieces of chain from an old chain that had reached the service limit, stretch-wise, and pop-riveted them to the fork shank in holes drilled to size. I finished it up by cutting off the tynes and grinding the end smooth. I would have made two chain whips but the thrift store only had one suitable BBQ tool. Today I'll check a couple of other nearby thrift stores in the hope of finding a donor BBQ tool to make my chain whip's brother.
