Mr.. Riley, In my research on saw mills I have come across the term quite frequently. In a saw mill it is those iron parts of the mill that connect the power shaft to the business part of the mill be it sawing or grinding. I thought that I had a reference to some of these being shipped to Virginia from Holland but can't seem to find it. The Dutch had more experience with power saw mills than did the English during the 16th, 17th and early 18th century. The English Sawyer Guilds restricted the development of power saw mills in England.
