What did you get for gear oil? Are there actually yellow-metal gears in the headstock?Made a big mess of my 706 today, decided to totally drain the gearbox oil, that means taking off the front panel as the drain plug is 3/4"above the bottom. A lot of paper towels later to soak up the oil that i didn't catch and i got to examine the gear box internals. Lots of black gunk in the bottom. I may put in a lower drain hole for the future. The apron drain is on the bottom so no issue there except getting small dish to catch the oil. Plan on picking up a QCTP in the near future.
