I have a saunders inproved automatic boring machine by wells manufacturing co. Ashaway R.I. That being said, has anyone ever taken one apart? I would like to clean and service this machine. The only way I see is to drive out pins that are hammered after they were installed. Any information will help. Also one small part on the housing for the depth stop has been broken off in the past. It is not a problem with function in anyway. Any parts location information ????

thanks
