Dividing Head Is Splitting Mine.

[Swerdk]

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

Cams are generally ground, but that is pretty much the limit of my knowledge on the subject. I can see how you could rough them out on a mill. Did a little search, here you go. Mike

I would think that for model building not using a grinder should be fine?

I appreciate that I thought it could be done. Looks like you don't have to do it with an automatic rotating table but I bet it would be a lot easier

Swerdk,

Talk to Brian about this. He has a build thread in the Stationary and Live Steam forum called 'Five cylinder radial with overhead cam', and he just cut his camshafts a few days ago in his thread.
