Cheap Peristaltic Pump for Mill Cutting Fluid

[nova_robotics]

I just put this together and it works fantastic. This little modification allows you to meter oils or other cutting fluids into the airstream of a cooling air nozzle. You can go from zero (straight cooling air) to a fire hose of coolant. Also it allows the use of pure coolant with no air supply. This was a very cheap and simple modification that I should have done years ago. It worked out so well that I'm going to be installing a similar setup on my lathe.
