I've posed this question in the Smithy forum (http://www.cnczone.com/forums/showthread.php?t=27555 (Information On The Smithy 1240 CNC Bed Mill?))
without any opinions from mech engineering types. I'm an experienced electronics guy but just above novice machinist. Below are photos of the Smithy CNC ready mill. The odd thing is that other mills of this type seem to use an oil bath in the gearbox, and Smithy uses grease "applied with a putty knife". Is this a good plan? Is this adequate? I'm considering the idea of installing a zirc fitting on the gasketted cover plate and pressure filling the gearbox with grease that way, but I know very little about the finer points of lubrication for this kind of service.
Here is a link to a picture of the gearbox with gasketted coverplate open:

And limit switch bracketts on all axis:
Opinions are welcome.
