I'm looking for a good soluble cutting oil. To clarify I am not looking to put water into the machine but rather make it easier to clean my slabs off.
Does anyone here use this stuff and if so what do you use?
Also what about cutting oil that is designed for metal with high lubrication? I know when cutting metal things tend to get hot s I thought that it might be a better solution.
I do realize that this type of oil, when cutting, does smell but being water soluable i'm not worried as it will come off slabs when cleaning.

What are you using now? Not sure water soluble and oil belong in the same sentence.
I use a food grade mineral oil that is pretty darn easy to clean up after. Not sure that food grade is a necessity, but mineral oil may work for ya.
Hopefully, others may have even better suggestions.

I use mineral oil from my local animal food warehouse.. almost all of my slabs get caked in sludge as the slabs fall on a low or sometimes into the basin as well. It takes a while to clean and sludge usually remains on the perimeter. but looking at some info it loos like soluble oils are hazardous in terms of vapors. |

If you'll come & get it, I have a 5 gallon container of water soluble metal cutting oil stored in my basement that you can have for free.
Water soluble cutting oil is fine for cutting procedures where your blade doesn't remain partially submerged in the solution when your saw is not in use. Water soluble oil will float to the top during storage or down time, exposing the lower portion of your blade to water. Don't ask how I learned this. Just let it be said that I threw away an almost new BD 301 blade after winter storage of a 10" saw.

The solution to caked slabs is put a catch in place. This, so as a slab parts off it falls on the catch and not into the sea of muk. Additionally, a bucket of water with a portion of dawn dishwashing liquid added also solubilizes mineral oil. Simple green works too, and smells nice... |

Buy a plastic tub and fill with cheapest Kitty Litter you can find. Stick the slabs in the litter for a day or two. Then put them in a bucket with a degreaser (simple Green, Dawn, Purple stuff, etc.)again for a day or two. Then just rinse off. The food grade mineral oils wash off easier and have virtually no odor. When I had a 10" oil saw I used food grade mineral oil and just washed them with a little dish detergent in the kitchen sink without getting in trouble. The stinky old Pella oil in my big saw got the kitty litter/solvent treatment. If you can find tech grade or white mineral oil it should wash off fairly easy as well.

Do your slabs get caked in mud? thats one pf my problems... ive got slabs soaking in water that i'm trying for now. |

I would be averse to using water in any of my machines.
Not all mineral oils are created equal. "Mineral oil" is a broad category. It can be used for any number of commercial purposes, from lubricating food-handling conveyors to laxatives for horses. Reputable suppliers of oil for lapidary purposes will have mineral oil modified to make it suitable for lapidary purposes, most notably additives to raise the flash point and de-odorizers.
The problem trying to use oils such as cutting oils, or kerosene is that certain materials have a propensity to absorb these lubricants (certain types of petrified wood). The only way to get these oils out is to actually bake the specimens in an oven. If you don't remove the oil, you will never be able to achieve a decent polish.

I found that if I hit the slabs with the stream setting on the hose 99% of the oil comes off. I would say all of the grit comes off and then I run them through soapy water or even the dishwasher if I an positive that all of the grit and gravel is off of the slab. Few things make them cleaner than the dishwasher.
Now, having said that, I own my dishwasher and do not have to have permission to use it for whatever I want. If you do it W?O permission, your wife might make a pendant out of your nards.

I once bought 5 gallons of mineral oil from Tony Funk ( catmandewe). It was very easy cleanup in water. Lately I've bought from Stellar Lubricants (Kevin Kessler). His oil is similar. It cleans right up in water. Lynn |

My big saw had a ledge to catch most slabs. Anything that landed in the sludge in tank could be scraped with a plastic putty knife before the kitty litter. By the way, if you have cats around use a tub with a lid. Auto parts suppliers sell oil absorbents that may work better but I never tried. I had a PetsMart store that sold the cheap litter that got the bags torn and were taped up. I picked the ones that looked still full and got a big discount.

I made one that will catch mose medium size stuff but need to remove it if I want to cit something large... and 1/2 the time they fall right into the sludge  |

Sludge coating on rocks is usually from going too long between oil changes or saws designed to hold less oil, which makes the oil get dirty rapidly and stirs the settled sludge back up every time it's used. If the oil is too thick the solids don't settle to the bottom well.
Water soluble oils for machining metals are not suitable for rocks, causes rapid blade wear.

If the oil is too thick the solids don't settle to the bottom well. Water soluble oils for machining metals are not suitable for rocks, causes rapid blade wear. I am due for a change but the current setup of the saw (homebuilt in the 50s or so). The tank holds 5 gallons but every other slab falls into the sludge it seems like. Because of that fact I haven't really bothered to change oil much. As far as blades go... because of the style of machine, I typically use the cheap blades as I won't get full life out of them just the way the machine is built... it becomes way thinner over time and one of these days its going to break because its too thin. the only real advantage this machine has over traditional machines today is that I can angle my vice apart from the fast it cuts decently fast. |

Sawdust works better than kitty litter. I squeegee the oil off the slab and then scrub the slab with the dust. Then wash with soap and water.

If you're looking for performance you could always use rice hull ash absorbent, if you want to pay for it.

I'll have to do some experimenting I keep a box beside my saw. If I'm not in a hurry I just leave them in the dust. If I need them I grab a handful and scrub them. I got the idea from working rigs. We used saw dust to glean the grease off the casing treads so the thread lock would hold. |
