I am interested in making model camshafts (4 8 inches long) for small engines Traditionally it appears you use a dividing head/ rotate table and tail stock on a mill to make camshafts. If so, is it necessary to automate the dividing head or does it work fine hand turning? I want to buy one that can obviously index, maneuver both vertical and horizontal, and have ability to be automated. Regarding automation, I am thinking about attaching a variable speed Sherline motor or CNC with step motor eventually. What I need to know is which rotating dividing assembly are your favorites. It has to enable me to attach a motor though. Also is a 6 inch rotating table adequate for my work or do I need a larger rotating table? My price point is under $900 preferably. My mill (to be purchased this fall) is PM 935 TV
