Anyone had experience with one of these Coolubricators...

[Washout]

This might help (I rarely do anything these days mechanical without doing at least a Sketchup first).
.
Hardest part was blind threading the air side 1/4" BSP thread.
.
You should be able to see on my video that all I've done with the "nozzles" is tie them together with the fluid on top so that it drips into the airflow below it. I was using an airbrush previously but that ate through fluid and fogged the entire workshop up in minutes.
.
Hope that helps.
