Re: Cam program and post needed for a cnc propellor carving lathe

I want to go with a lathe configuration because it will machine both
top and bottom of the blade. A router or mill will do only one side of
the blade at a time. I think this method will have a faster cycle time
with less fuss. And the saw blade can be changed if necessary to a
vertical belt sander for finishing.
Thanks, Larry reiss Omaha, Nebraska
