[R-390] Gearbox .avi

[Graham Baxter]

I've often wondered about the optimum tuning torque too. I have two
EACs, one of which I have given a full strip and cleaned, the other
just a cotton bud and relube type of service. The one which has been
completely stripped I can turn with just my little finger in the
flutes of the knob. The relube one needs an index finger. I used ISO
68 machine tool slideway oil on both.
