Got the lube working to the knee and screw on my Kondia CNC mill, ISO 68.

Tried oil meter size 0 directly (no tubing) on the original Bijur pump, nothing comes through at all.
Yes, I did wait a good length of time, not a drop out and the pump handle did not move.
When size 2 tried, flow was good.
The meters were supplied by Arceurotrade a few years ago.

Is it possible the Bijur pump pressure could be too low, by design or age ?

The oil passages were blown out with the knee loose (no gib) and they all seemed good.
When connected, the slides get adequate oil, but the dovetails are definitely much lower, but usable.
If I ever have to remove the knee, I will drill additional passages and have separate meters to the slides and dovetails.

Installed a meter size 1 to the screw.
Interesting to note that when the knee was gib-less and the screw liberally lubricated by hand, I could spin the Z axis drive pulley and the screw would continue to coast for several rotations.
It doesn't coast with the gib fitted, but the feel from the pulley is good.

Now working on the saddle.
The X-axis has one meter per side, with an internal "T" passage to get oil to the slide and dovetail.
The Y-axis has one meter per side, but no internal "T"passage, and no delivery to the dovetails.
Perhaps it is normal to apply lube manually to the Y-axis dovetails.

Is it normal not to supply the Y-axis dovetail ?
