Drawings for no fog coolant mister
#9
I finished my no fog coolant sprayer some time back, and have experimented with it quite a bit. I found that the nozzle could be done away with altogether, or the hole size should be increased to about 0.090".  It seems to work much better this way. In my case, I made the hole in the nozzle larger. The weight of the nozzle helps to counterbalance the weight of the mixing block, and it stays in position very well.

I run a single regulator set at 10 to 20 PSI, and with the two needle valves, it can be used with just air, just coolant, or with both. Optimum settings seem to be with enough air flow to gently push the chips away from the cutter and just enough coolant to barely make things damp. You can mill for hours and the coolant level only drops an inch or so in that time. The coolant needle valve is very sensitive, so have a little patience when getting it set.
