I see. Being I worked in a engine machine shop I know what some of the costs would be. If someone wanted to copy this motor for example, they first would have to find a machine shop willing to do the work. I am going to guess probably 5k or better in just machine work only. I know the girdle by itself is very time consuming. All of that machine work is time consuming and costly if you don't have the equipment available, and can't do it yourself.
