That green is pretty. Looks like kind of a lemony green.
Do you use a second - settling - bucket Donnie? (I don't know anything about it really, but the old timer at the club was explaining that to me the other day and it seemed like a sensible idea - keeps the oil a better color.)

Bluesky, no I don't use a settling bucket, at least not yet, anyway. My bucket sometimes doesn't clear the bottom of the cart & settles on the edge of it so it accomplishes the same purpose. Other times I there to grab it before it comes off anyway or I just take a rock out of the bucket to lighten it.

Um, I think I used the wrong word (this is all new). I meant for your oil - when the oil comes out of the saw, it can go into one bucket, then overflow into another bucket before being pumped back into the saw. All the rock dust ends up settled at the bottom of the first bucket instead of being recirculated.
Now I'm curious about the bucket you refer to - is that the weight bucket for the gravity feed? (Hope you don't mind my questions, trying to learn.) Sorry to derail your thread.

instead of changing your oil when it gets dirty, are you filtering it for re-use? We do it on a regular basis, and it sure saves $$ on oil. We use the two bucket and grocery bag method and the oil comes out clean as the day we put it in. Once in a while, depending on what was cut and how long we let it go, it becomes color stained, but still clear and clean. Costs us about $80 to refill with new, $0 to reuse.

(Hope you don't mind my questions, trying to learn.) Sorry to derail your thread. on smaller slab saws, especially 10" ones, there is no pump for the oil. There is just a tank under the blade holding 1.5 to 2gal of oil, and the blade sticks down into the oil for about 1/4" I have seen multi-chamber systems (i.e., two bucket) on larger 18"-30" slab saws where the oil is circulating and pumped onto the cut. I think Covington even sells a 3-chamber box for this purpose. Periodically you clean the tank to remove rock sludge, and filter the oil.

Ah, I see. We have the two bucket thing on our 12" saws, but I'm thinking it's probably an after-market type thing. Thanks!
And now, back to Donnie's beautiful slabs!

Thanks, Daniel! As to the bucket, yes for gravity feed. Phil, I do filter the oil but I'm impatient so once it's cleaned out of the saw & filtering I just go ahead & put fresh oil in. Once the old oil is filtered out I add it back in when I need to add more oil to the sump.

(Hope you don't mind my questions, trying to learn.) Sorry to derail your thread. You're describing something like a 'clay trap' only for oil - that's a good idea. It could take a long time for fine material to settle in oil I presume. Makes me wonder also if so-called spent oil can be stored in large 1 gallon pickle jars for weeks or months then slowly poured off into brown paper bags (leaving the bulk of the crud on the bottom of the jars) to filter anything left? If that works it seems like one could do it several times before the crud in the bottom of the jars gets to be too much - at which point I'd probably chuck the jars rather than trying to clean but...? Anyway, I hadn't thought of this and it piqued my interest.

Frank, We just let it settle in the paper grocery bags, (doubled) and the crud ends up nice and dry and we then fold up the bag and send it to the recycle. Some folks even burn the residue, but I can't see it. 95 % of your oil will filter in about 2 days. You can dump that back in, put it in jugs, whatever, and the last 5% can be set aside and just sit in the bucket filtering till done. We use odorless mineral oil in everything but the trim saws. Since we started using it, I've noticed that in a short period like overnight, the crud has settled and the oil on top is crystal clear like the day we bought it. And we've been getting NO NASTY OIL SMELL!!! Actually, to clean and filter, we have to stir everything up to get it back into suspension so it drains out. Our saws are remaining amazingly clean since we switched. A nice side effect is that misting has been reduced by about 80% even on our larger sump or sling saws.
