Mill Spindle Overheating (Rockwell 21-100)
So I have recently acquired a Rockwell 21-100 milling machine. I originally purchased the machine to use the head since the seller told me the machine was missing the table but turned out everything was there. The machine looks nice and is smooth with little wear. As the title states, the spindle gets very very hot when at the higher speeds.

Here is a photo of me moving mine. If you are really going to look for one you may want to keep an eye out for a Rockwell 21-122. It looks almost identical but has a built in horizontal mill as well. The one slight drawback I have found in this mill is that it does not have a quill feed. Chris.

I Just Bought A Rockwell 21-100 Milling Machine
The little Rockwell is a quality machine that was used by the Navy who bought them by the truck load for the simple reason, it had a small footprint and even something as small as a submarine had room for a 21-100. In fact, all the manuals and documentation for the 21-100 are DOD publications...and they're a bit weak if you ask me.
