So with moving and all I've been looking at other methods for fluids so I can cut when it's 20 below. Mineral oil can but gets thick.
I was wondering if anyone used rv antifreze. (Would be year round). Drinkable material and not supposed to rust even though water based.
Anyone try this yet?

I have definitely heard of people cutting with RV antifreeze but I think the big question is what size saw. I believe anything over 10" needs oil. There's been discussion here recently about adding heaters to the slab saw to keep the oil "thinner".

I used to cut with just water on a 16 with no blade wear difference time saved cleaning probably makes up for the slight extra loss if it doesn't rust. |

Use oil for slab saws and water for trim saws under 10 inch.

Whenever I use Propylene Glycol antifreeze it seems very slippery. Though it is also viscous when cold. Ethylene glycol is nasty stuff, wouldn’t try that.

I use EZ Cut additive in my 7-8 inch. Add it to water. I'll be using that or RV stuff for my 10" whenever that gets set up.

Its been discussed before but Barranca Diamond says don't use automotive antifreeze - its toxic. and they say don't use RV antifreeze its thought to be non toxic if breathed in normal quantities, but I'm not sure the manufacturer's tester envision the misting of a rock saw. But RV antifreeze has no lubricating benefits, has a persistent odor, and clings to your hands more than mineral oil. Here is the link to the Barranca Diamond recommendations for lubricants. www.barrancadiamond.com/pdf/tec/bd_slab_saw_coolants.pdf Glycols run the gamut - and are even in the substances that may be causing problems in vape use. Not for my shop thanks. |

i have been using antifreeze for a month now in my 16" saws going to try the 18" later today so far im liking it the one draw back is the blade needs dressed after 40 cuts or so but i can handle that because clean up on slabs are awesome compaired to that nasty oil also cleaning out the saw is a cinch just drain and wash out !!!!

Do you have any problems with rusting? At this point I'm thinking about getting some and if it doesn't steam maybe add a slight amount of mineral oil... or would dish soap be better? |

I'd use strait water but it has no rust preventative if it sets |

It's oil only for me in everything over 8 inches. If I cut stuff that was a problem in oil I would use the JBros lube Kool that I use for trim saws and drilling, just to cut the potch or whatever it was, then go right back to oil. I've been in a shop that used to antifreeze, got a headache and a cough every time.

Glenn What about diesel fuel? jamesp uses that in all weather successfully The massive saw shops in Brazil use diesel fuel cut about 1/4 by say 10W-30 oil to reduce flash point. Can be quite nasty. Please use in cross draft in an open shed. |

Diesel/motor oil mix stays clearer than other oils I have ever used.
Particles fall out of it quickly.
And the particles form a 'rubber' matt that be peeled off the belly of the saw.
I believe the flashpoint is way reduced with the addition of motor oil. Worth researching.
Lubrication properties probably unbeatable, better than Covington saw oil IMO.
-20F ? Do you have a choice ? Got a sump/engine block heater Glenn ?

How did you learn what the Brazil saw shops use?? I met a fellow rock hobbyist that has a rock shop in Indiana. He visited Brazil 3 weeks out of the year selecting sawn Brazilian agate slabs at different sawyers and had them shipped back in 55 gallon drums in an oversea container. Most of his sellers were small family operations living in the agate district. A 55 gallon drum would hold 660 pounds of polished slabs. The Brazilians graded them roughly AAAA AAA AA A B BB BBB BBBB. He made and sold candle boxes. Hard to find such quality anymore. He used to pay about $3/pound. The Chinese bought a lot of the mines out, raised price 3 to 4 times. Made dyed agates out of most of them. |
