I'm no expert, but I always fill my 18 inch saw to that the oil is about 1/4 inch higher than the diamond part of the blade. I'd be interested to hear what others say!

Herb is right, about a 1/4" to 1/2"..... That's on my 14"..

If the oil is higher than the diamond zone on the bottom of your blade you are probably throwing too much oil, and making more mist than you need for the saws operation. JMHO Oil depth does effect mist production and general mess.

The depth of the oil over the bottom of the blade varies with my saws. With the small 10" slab saw about 1/8" to 3/16" works great, but the FranTom 24" saw has a stepped bottom where oil can puddle and lower the sump level, so I keep about 3/8" of the blade submerged when all the oil has drained into the sump to ensure that the blade will remain in oil when it's running. My HP 18" saw also can build up a puddle on the slab catcher tray so I fill it slightly more. I agree with the others that 1/2" is the absolute maximum, and probably too much with most saws.

Thanks for everyones help. What oil do you use and when do you decide to clean it out?
I use light mineral oil $20 a gallon from a recommendation from the rock club guy. Just cleaning it out now. Looks like milk chocolate.

I use Stellar Lubricants saw oil, about $12 or so a gallon in 5g pails, I pay considerably less by the 55g drum.
Best time to clean IMO is when the saw snot in the oil is visible on horizontal surfaces after cuts. Are you reclaiming oil from the used stuff?

Yes, I have it draining in a paperbag sitting in a 3 gal bucket with holes in the bottom. Have that bucket sitting in a tall bucket. Should have it filtered in a few days.

1 inch on 14'' on up. more spray flying in tank helps to cool tanks supply.
Lapping just a 1/4 -1/2 inch well start to heat up tanks supply. Not good to let tanks coolant get above 100 degree F.

Jack Mike in Dallas you should Know better. I am not a saw guy, but this statement about coolant in the tank requires a bunch more evidence to back that statement. Who heck is Mike in Dallas? There's no such person in this thread. OP, pay attention to others in the thread. You'll get good guidance. I'm not a saw expert, but the 1/4" guide above the diamonds seems to be a pretty good start. That's based upon everything I've seen here. |

I don't get hot oil the way I run my saws, but then I'm not doing production either and I especially don't like oil mist or oily floor in my cutting garage. |

Makes sense now to some degree. I'd still like to see evidence related to what was claimed...in that the tank oil should not reach (or go over) 100 degrees. I've never seen that addressed here. Blade depth in oil was always the issue, and Fossilman has posted numbers that I've seen here before. ETA: If that is the case (about the temp) how much cutting would it actually take for that even to be close to being an issue? |

Someone might be able to make an argument for 100 C but if 100F were the case many of us better shut our saws down during the summer, it gets well over 100 F outside. I have to assume he was thinking C when he wrote F, but around here thet let us smoke pretty much whatever we want to, so... |

the face of cut at kurf on sides of blade get very hot. contact point of diamonds an the metal matrix holding diamond in place. can't remember the book i think it was 1964 "Lapidary Shop Help.
That the cutting face is close 270 degree F. when tank oil is over 100 degree F.
Though Carbon boiling point is 3004 degree F.
the metal holding diamond in place needs much more fluid on blades radius to wash cut, an cool coolant.
Trim saw 1/4 1/2 An apron.
coolant i use has a flash point of 351 degree F.
