I have the plans for the arm pretty much drawn up, just need to get them posted so that people can see them.  getting my thoughts written and posted up on this is proving to be more difficult however.  I think that what will happen is that I will post an a general overview, as well as several more in depth musings.  the research involved has enlightened my about the context of studio pottery and how it evolved in the face of the industrial revolution. the quest to regain employment and dignity after ones line of work gets overtaken by technology ,  and how tools interact with technique to form an aesthetic .
