I'm retrofitting an old BP hydraulic tracer mill and was looking for different ways to mount my servos and came across this picture. Does ayone know how lubricating the ball screw or nut is done on this arrangement?

I like the idea of locating the motor off the end of the table but can't think of a good way to oil the nut since it is spinning aside from a drip oiler on the screw. Seems a little mess long term.
