My Shizuoka, and I suspect the mill on eBay, are just like a Bridgeport. The quill has a post that travels in a slot in the front of the housing. A ball screw drives the post. I've seen Bridgeport conversions that drive the post, and others that have a clamp added to the bottom of the quill. It's hard to find a place on the Bridgeport to mount the motor and belt and still have access to the head adjustments. This is another example of how converting an existing CNC machine is much easier and cheaper than converting a manual machine. For my Bridgeport and Cincinnati mill, I am hoping to make a new head that replaces the quill with a rigid spindle which mounts to a dovetail slide between the spindle and ram. -- Kirk Wallace http://www.wallacecompany.com/machine_shop/ http://www.wallacecompany.com/E45/index.html California, USA ------------------------------------------------------------------------------ Everyone hates slow websites.
