Oiling a Myford S7

I have recently acquired an early Myford S7B with the spindle oil
supply reservoir and drip feed sight glass built into the headstock.
Can anyone give me some guidance as to how the drip feed should be
set? I've tried adjusting it to keep a constant level in the sight
glass window, but this is almost impossible (it either slowly fills up
or slowly empties), and in any case the amount of oil used seems
excessive - I empty the reservoir in less than an hour. On later
machines with a wick feed the Myford manual says top up the cup twice
a day, which can't be very much oil at all.

Any advice appreciated.

Thanks

The sight glass is to see the oil drip, according to the Myford
manual: "the drip should be set as slow as possible, but if
prolonged high speed is undertaken, the rate may be increased."

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.
