Fixing a Leaky RF-45 Mill Head - Grizzly G0519

[henryarnold]

I don't have a clean tank so I used my shop sink with Dawn soap. I dried it off well to avoid any rust.
   
Here's a closeup of the brown muck that was inside my mill head. Obviously I cleaned all of this out.
   
I painted the interior with an industrial oil base paint. The proper paint is called Glyptal but it costs $50/quart. I think this paint will do the job. Paint is an optional step that is supposed to keep oil from seeping. I doubt any oil was actually seeping out. The leak I had was all through the quill.
