Then a drill chuck, say a 1/2" ball bearing chuck, and maybe some "solid sockets" for end mills. The endmills will work in the collet chuck as will large drills But for heavy milling, solid sockets project less (more rigid) and are more slender, so they get in places where the collet chuck might bump. ...

How Does a Vertical Roller Mill Work? The working principle of vertical roller mills is relatively simple. In a rotating drum, grinding media (steel balls or ceramic beads) are fed through the mill's inlet, and the particles are ground into smaller sizes by the mechanical forces generated by the motion of the drum.

I dropped the table in the mill vice and locked it down quick and easy for a test cut). Then bolted the work piece to the table. Tried a little side milling and while the cuts must be ridiculously light and the feed ultra slow, I'm able to mill the radius I need. It will take a while to do the whole piece, but at least it cuts with minimal fuss.
