I just bought an oil mister for my Mill. I have an air regulator (old and used). I have an air operated foot switch for my sandblaster cabinet that I am thinking about using to control the mister. The air switch will probably work better on the supply air side than on the low side of the regulator. I just don't know if the constant switching 150 psi air on and off is going to kill the regulator. I temp hook it up and using dark cutting oil and it's working ok. Not sure about long term. Controlling the oil mister with a foot pedal seems like a good idea to me. Any thoughts.

You could wire in a pilot valve.
Supply the desired air pressure to the pilot valve and let the pilot valve do the work, but that would require an electric/pneumatic switch to be added

I purchased the mister through Amazon. It was $19. Had good reviews (time will tell). The unit's push to connect air fitting is listed for 8mm tubing. However 5/16" OD tubing worked fine. For now I am going to use the Oatey dark cutting oil. It's ISO 68 viscosity.

I set up a mist system on the mill using a water filter housing as the reservoir. I used a pilot valve as recommended above, but you need one that exhausts the pressure from the reservoir or it will continue feeding oil after stopping the air. Set it up with a foot switch as well as a continuous on switch. Thought I'd use the foot switch to lubricate and blast away cuttings as needed, but never use the feature. I turn it on with the on/off switch and let it blow for the entire operation. Your habits might be different.

I am trying to wrap my head on your set up, especially with the foot switch. The reason I ask is because don't you get some oil back feeding through the exhaust port on your pilot valve when switching off electrically as the reservoir is depressurizing. I am thinking that the viscosity of the oil you're using has a lot to do with it. Since I am using the Oatey Dark Cutting Oil, I am having to use higher air pressure to pull from the bottle.
