I'm going to rig flood coolant on my horizontal saw, when my back heals up.
My question is, my shop is not heated 24/7 and there is potential for the sump to freeze.
I'm using CRC water soluble oil as the lube/coolant, does the oil do enough to keep it from freezing
or do I need to add something, and if so, what?
TIA

Throw some in a plastic cup, mixed as you would for the saw, and stick it in the freezer...

"If" an additive is required, I'd think winterizing antifreeze for plumbing/RV antifreeze would be fine, and shouldn't take much unless your shop sees hard freeze weather for extended periods.

The machinists here may have better suggestions.

Thought about regular antifreeze, but didnt think about the RV stuff.
I thought about doing the cup test after I posted too. derp on me
Be a good compatibility test as well
Supposed to be 20 below here tonight!

If anything I too would go with the RV antifreeze over regular antifreeze. Here is a good link for more info on the RV antifreeze:

Or you could use Windshield Washer Fluid. I have even read about using a magnetic oil pan heater but if your saw is like my Jet saw, the tank is plastic. If its metal you would need to leave it plugged in but its an option.

If the tank is metal or with some hacking you may even be able to use one of these?

my only concern with antifreeze is screwing up the properties of the coolant.
on the other hand,any hting to clear chips and promote blade life is better than nothing.
This is a cheap ass central machinery saw, with a shop built frame and chip/coolant pan.
Had a system on it, but the pump died. Plastic tank. I'm going to make a new tank
and have a new pump. IF, my back ever heals up and I can get back to the shop

I'll be interested to hear the results of the freezer test, but even my chest freezer won't do -20. The RV antifreeze should be straight propylene glycol, with no additives, which is why I thought it the better choice for saw coolant... Fewer things to screw up the properties of the saw coolant. I would expect (but don't really know) that it would behave well with the saw coolant since they are similarly water soluble.
