I'm about ready to get started on my air pressure flood coolant system. The
idea has been bouncing around in the back of my head for quite a while, and
the one thing I haven't quite got figured out is the method for checking the
level in recovery tank and the pressure tank. I was thinking I'ld weld a
couple thicker plates on the side at the top and bottom, pipe tap them, and
put in some right angle hose barbs with a bit of clear tube. I have used a
tight fitting brass hose barb and a stainless hose clamp to repair an
airline in the past. It worked fine. In this case though the tanks will
most likely be fill with a petro chemical of some kind.

I'm trying to determine which tube I can use that will take the pressure
(probably pretty low based on some experimentation), be able to withstand
the coolant in the tanks, and be nice and clear for visible check of level.

Tygon, or more generically, polyurethane fuel hose - seen on
motorcycles, lawnmowers, chainsaws... often but not always tinted, but
see though (even if tinted) and compatible with petroleum.

Will it handle the pressure on a continuous basis? I expect the system will
get left at about 20-30 PSI all the time.

Polyurethane tubes can be had in diameter up to 1" i.d. that will withstand
250psi continuously.

The little 1/8" bore stuff I use for pneumatic interconnects is rated at
250, but I have seen it take 600psi for hours and hold.

The type with white diagonal reinforcement threads can handle some

Just out of curiosoty..why a pressureized coolant system, when one can
simply pick up a cheap pump for less than $10 and not have to deal with
breathing coolant in the air?

1. Water based coolant is not an option. None of the pump systems are
rated for potentially (if a bit of a long shot) for potentially flammable
liquids.
2. A pressure system keeps that spark generating motor at the whole other
end of the shop.
3. I plan to use some relatively large tanks for long runs.
4. Why would a pressurized system put any more coolant in the air than a
pump. No reason at all. It will come out of the nozzle as a solid liquid
stream just like the water comes out of the pressure tank on a well.

Yes, I know modern well tanks have a bladder in them, but I worked on a
water distribution system with my dad when I was a kid that didn't too.
Just bleed and air. Besides it will be fun to build.

Coolant pumps'll pump cutting oil, just not as fast. You won't have any
problems at all with a typical coolant pump. If it's not a totally enclosed
CNC machine, you don't need a vast flow.

I am not seeing one rated for oil or other petro chemicals for less than a
couple hundred bucks for just the pump. Tank, filters, etc are extra. Not
sure what cheap pumps people are talking about. Any ole water pump will
work for a water soluble coolant. Probably could use a cheap swamp cooler
pump for those coolants. Used to be about $9 whole dollars retail for the
economy ones when I was in the hardware business. A good one was less than
20.

Get some aluminium or steel block, some drill rod and a DC motor.

Make a pump as a project. Use a casserole dish as the sump.

Use a windscreen washer pump as a prototype, it'll be in the right ballpark.

Long drive rod, like a high volume farm well pump to get the motor away from

Not that long. If necessary, mount a thin disk on the shaft. It'll act as an
oil flinger and stop any oil migrating up the shaft to the motor.

Oil is indeed a "potentially flammable liquid"...though Ive tried in
many occasions to set my lathe on fire while generating sparks and a
****load of red chips into pools of it.
All have failed to ignite it btw.

Fun, hopefully is the sole reason, because frankly..I cant see any other
reason to do so. Im curious though..how will you be refilling your

Oil pumps from scrapted automobile engines are gear pumps and even have a
rudimentary suction filter on a lot of them. The can have an extension shaft
attached and you can drive it with any small motor.

As oil pumps are hardly ever replaced, they should be cheap.

Shrug...do as you choose Bob. Everybody is free to set up their shop as
they choose.

As for me..shrug..one of my lathes and one of the mills have $19 swamp
cooler pumps on them and they gush out rather nicely. Head is about 3
feet and length is about 5-6 feet.

Castrol Ilocut goes through them nicely. I have about 40 gallons of the
stuff, compliments of a company after a Westec about 8 yrs ago. I
believe its about SAE10 weight. Maybe 5 weight.

Shrug. Keep us posted on your pressure oiler. It does sound interesting.
