Re: [mill_drill] Gear head Mill - Oil around Spindle
- Yes slow but always there.
- Here it goes; I used 1 qt of 90w Slick50, and the remainder 90w gear
lube. I've used Slick50 in my car transmission and noticed a
reduction in gear noise and smoother operation. I think the Teflon
additive is a good Extreme Pressure (EP) additive and cushions the
metal to metal contact that causes wear. I didn't want to use 100%
Slick 50 due to the expense and the other lube also has EP additives.
I've noticed a slight reduction in the gear noise at the highest
speed but nothing appreciable. It does run smoother though and
generates less heat. I think 30w is not sticky enough to be a good
gear lube. I haven't looked inside to see how the lube system works
but I bet it is a splash system and you want sticky and the EP
additives such as Teflon and other solids. Motor oil uses anti wear
additives two different lubes for different purposes. Stick with lube
that has the EP additives. DISCLAIMER: This is only my opinion, I
don't want to be liable for any damage other that what I cause to
Other things I've built since receipt is a jacking caster base that I
use under the stand so I can move the thing around and a flood
cooling system. I'll post some pictures when I get a chance. The
caster base works better than some mechanical engineer friends or I
thought it would. I used 2x2x0.125 angle to frame the base. Then
welded 2-4x4x0.25x4" angle at the back corners and 2 as outriggers at
the front sides. I used 2 fixed 3" casters at the back and 2
modified swivel casters at the front. I'm having more fun tricking
this thing (we now call Igor) out than using it for my original

you use, Craig? Any more opinions?, facts!?!?.......
