Look at a mist system.

After using and being around a number of them I’ve settled on the little Noga Minicool misters. Relatively low cost, easy to use and easily pack away in a tool drawer or cabinet when not needed. If you watch you can catch them on sale now and then from various tool vendors.

I've got a cheap mist cooler (30 bucks on amazon). It's "OK" - Fiddly to get just right every time it's used. In my head a flood coolant to keep chips flushed away from the cutter seems better... and no fogging up the shop with god knows what chemicals.

Not sure how compressed air doesn't evacuate chips. I've fluted hundreds of barrels with just a mist system. Much easier to clean up. No guards required. YMMV

I'll try a Noga or a proper kool mist system.

Use the kool mist coolant

That's what I've got. I ordered the Noga mini.
The cheap chinese mister will probably be used for just air to keep chips off my threading tool when I'm threading up to a shoulder.
What are the considerations of using water-soluble coolant (in a flood application) interacting with way oil on slideways? Don't you also need skimmers, etc. to deal with the tramp oil?
It would be simple enough for me to add a drain to my chip tray to enable use of flood coolant, but for the few times it might be beneficial vs. brush-on I've been hesitant to go this route. I know there's emulsifying way oils that "mix" into the coolant and don't need skimming, but way oils getting washed off leaving the sliding surfaces dry doesn't seem like a recipe for success. Way oils are designed to prevent metal to metal contact, and coolants have the opposite purpose. On manual machines with exposed ways, isn't this just a bad idea?
Is this why seemingly everyone here using coolant for chambering uses a dedicated catch basin under the barrel?

I can't speak to water-soluble coolants - All I've ever heard is that they are a pain in the ass for a home shop.
But... at least for my system, the catch basin is to keep the oil clean and separate from the lathe chip pan. The chamber flush system is completely isolated from the rest of the filth on the machine.

You wont believe the overwhelming stench youll get one day walking into your shop with water soluble coolant. I can still smell it

My shop is air tight and have zero interest in finding out.
Very very true with the old type of water sol. The new synthetic coolants do not go rancid. I have been using a Castrol fluid in my lathe. Works great chambering and turning. Once you use coolant when turning, you won't want to turn dry.

It is going to happen. Youll need a skimmer and test the concentration daily

No mess, do it right.
Catch pan with return back to sump:
Rubber flap keeps the coolant in the pan.
White flap on headstock side fits under the chuck and keeps coolant in the pan.
If you are spraying coolant or oil all over the place after doing the two mods above your pressure is too high. You want flow, not high pressure.
This system is over 25 years old (it looks it!) and works great.
