Before turning on my Industrial Hobbies Mill which is in the last stages of being converted to CNC, I decided to open the mill head to check for grit/dirt in the oil. When I opened the mill head, it looked like all the gears were rusted, but what I found was a sticky, brown gooey sludge covering all the surfaces.

After several hours of work with paper towels and brake cleaner, I finally cleaned out all the sticky brown goo. This is a new and never run mill. Check your mill.
