makeshift hybrid drip-mister?

[Tony]

greets all.. before I potentially waste a few hours reinventing the wheel thought I'd post an 'idea'
I'd like to try as a stop-gap before I build an official mist coolant system for my cnc router.

i currently have an air loc line going right to the cutting area.. i'm thinking about adding a drip oiler
(gravity + ball valve) and T-ing right into the loc line. . . figuring a drop of oil now and again in the
air jet will do the job.

but i'm wondering if this will work and two doubts -- for anyone who might've tried this:

1. will i just end up coating the inside of my loc line and blowing back into my oil can?
2. will the venturi effect over power my drip and just suck my oil can dry in no time?

thoughts/suggestions appreciated. i'm gathering parts for a proper mist system; i'm hoping for
a temporary solution while I get those together.

Thanks!

Do a search, here and on the other boards, for "Fog Buster". A guy who goes by cfellows came up with a really
inexpensive and super effective cooler that doesn't get everything wet, keeps the chips clear, and is effective
at cooling the tool. I'm making my own version of his but don't have it finished yet.

Chuck hangs out on the Model Engine Maker forum. I think the article you're referring to is here...

Instead of pressurizing the bottle could a gravity system be set up and the air just used to atomize the liquid?

whats a drip mister?

with a mister the trick is of course to avoid a fog in the shop - something that has a high probability of happening without the right design. There's lots written here and on PM, one element of success iirc is pressurizing the liquid as well as (obviously) the air....many posters also advocate a particular size of mig tip as being just the thing for a nozzle. Some searching should turn up lots of ideas

The fog buster design with a pressurized container works extremely well. It doesn't make fog, it transfers droplets of fluid to the cutting tool and makes almost no mess. I have a solenoid valve turning it on and off. However to stop the fluid flow you either need a second valve or a do what we did, install a quick exhaust valve on the inlet to the container. When the air goes off the quick exhaust dumps the pressure off and the fluid flow stops.
