Mine's the wick feed version and running all day you'd be lucky to use
more than 1/2 the cup! It needs very little oil, I recently replaced
the rear bearings on mine, and there was no visible wear on the front.
Original hand scraping marks were still there.

The rear ones had a rough spot, probably from when the lathe was left
unused for several years. They were surprisingly cheap at 23.50 the
pair, delivered, by my local bearing stockist. They are standard 7205
Angular Contact Thrust bearings.
