How do you filter out the grinding residue from the oil? I am using equine mineral oil in my slab saw.

I haven't done it myself, although I plan to: put a paper grocery sack inside a 5 gallon bucket and fill it with the oil. The sack will allow the oil to pass through while capturing the mud.
I have rectangular buckets, so I thought I would drill holes in the bottom of one and put the paper sack in it, then put the bucket with holes inside another bucket. That way it's easy to reclaim the oil without having to take out the paper sack.
Hope that helps! I'm sure others have their own techniques, but this is the approach I've seen most often in the threads here.

I use the two bucket method. One bucket - the straining bucket - has holes drilled in the bottom and sits inside the other bucket. I have about four screws screwed partway into the straining bucket about half-way down to allow a gap. I put two paper sacks in the top bucket, empty the saw into it, and then let it sit for a couple days. Sludge stays in top, clean oil in bottom.

What they said but 3 paper sacks . Depending on how much oil you have if you keep the sludge in a bucket any remaining oil will rise to the top and you can pour it off.

I use the two bucket method also.But I'm curious to see if there are any other ways to filter it. Mike

I use a piece of expanded metal that fits down into the top of the bucket. Only have one grocery here and no choice of paper bags. Just plastic! So I bought a bunch of old vacuum cleaner bags at Good Will to put the used oil in. Set it next to the wood stove for about a week or 2. And clean oil appears.

some mineral oil is thicker and will filter slower; keeping it slightly warm will help speed things along
