This was by far my largest turning yet 17″ diameter x 7′ long. It was a commission by a local contractor as a jig for making bridges. The wooden trunion was used to set up the pieces, then the real metal was inserted.
It was over 500 lbs. when we started. I used Ray Frase’s Oneway lathe to turn it. It took four of us, a fork lift and a chainfall to get it in place. It was amazingly well balanced. Carl Pardy helped me turn it to size. In total, it took us 12 hours.
