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.
