Jet JMD-20VS-1 variable-speed mill-drill

The spindle bearings were loose, and several components in the variable-speed drive had worn out to the point of rattling. I eventually replaced it with a full sized Bridgeport clone, which was far and away a better machine. This particular style of mill-drill was essentially a lightly altered copy of a Clausing industrial drill press.
