I am looking to use coolant on my lathe and mill, I was thinking of using one of the Harbor freight parts washing tanks with pump. Has anyone done this? I would just hook up a drain tube that would drain into the tank, that way I could use it on the lathe and sometimes on the mill.
Certainly nothing wrong with the idea if you can rig it to work. The biggest problem you'll have is getting the coolant to return to the tank. If your lathe or mill aren't built for coolant, could prove quite challenging.
It's a good idea to have a back splash for your lathe. Keeping coolant away from the chuck is virtually impossible, and it makes one hell of a mess.

I put a pump intended for a garden fountain on a horizontal band saw I acquired a few years back; it was cheap and it works well. But the saw already had (most of) a cooling system on it. The pump was shot.
It is a good idea to put the pump in a nylon mesh bag to filter out the big chunks, though...

What I have on mine is what looks like a swamp cooler water pump. Close to it, but huskier than those I used in El Paso in the 50's. No telling what is used there now.

Now that summer is nearly over..swamp cooler (evaporative cooler) pumps may be coming on sale. They work very well for coolant pumps for saws And lathes. They are intended for water so dont pump high sulpher oil all that well if you need a large head distance but for water based coolants..work very very well.

i actually dont know what a "good fountain pump is", never having used one.

These are typically available at your local Ace Hardware for $15 and up. I cant imagine them being on sale much cheaper than that.
That looks like a modern day - beefed up version of the ones I replaced in the
50's. I don't think the old ones would be allowed anymore due to OSHA and a few other laws...

Most of them are indeed open motors with a simply plastic splash guard semi protecting the wiring. Sometimes.

Nope, still sold. We still use two of them.
The reason the open motors are still allowed is they are fastened in place so the motor can't fall into the water, the body of the cooler is grounded, and you're not supposed to be working inside the cooler without cutting the power first. (Yeah, right, Suuuure...)
But I'd be careful using them for machine coolant, the straight blade impeller with pretty large clearances can't put out a lot of flow or too high a head. The average 24" lift inside a cooler is approaching their practical limits. And it's too easy to forget they're open and overfill the coolant tank, or splash coolant on it and overwhelm that little drip cap.
You can get small submersible fountain pumps that will give you a lot more flow and head (and you can't drown them accidentally) for only a few dollars more. And wrap the whole thing in a stocking to keep the swarf out.
