Speaking of knuckle-draggers............. Here we have someone who does not do any metalworking, at least there are not any posts that I remember. And he posts to a metal working group, but not about metalworking. Obviously not the sharpest knife in the drawer.
Now back to your regular program. Today I was at the local scrap yard and found some metal pieces that were close to being right for a shaft coupling. They had a 1.5 inch hole in pices about 2 inches in diameter. Unfortunately they were made of lead. Came from one of the local hospitals and had radioactine material inside at one time.
