saw cleaning day. Tried moving an old bucket of murphy oil soap. Bucket burst all over my patio. Wife mad as a wet cat!!
So i ended up cleaning saw...... while i was cleaning patio in case i did it when i got to the saw. May as well do it while there is already a mess.
Now heating the inside of the saw so the oil drips faster.
Yuck

Nasty indeed. What had you been cutting? Limestone blocks or plasterboard? A clean saw is almost as much fun to contemplate as a clean car. No go get it dirty.
-
Most of this gray goo is from the teanaway basalts jasper and alot of crap rocks i thought where going to be good cutters.
The teanaway jasper is greenish blue in color, but when its gut it makes gray sludge.
I have the heat on hogh in my saw now, the bucket of goo went down 3/4 of an inch over night.
I also have a test bag, Charcoal Briquets bag actually, where i tore off the outer clayed type paper layer and using the two inner layers to double strain, i am findings its WAY slower. probably going to take two weeks to strain all this oil back into the saw. :Bash:
-
but heated oil flows faster, so i will have to keep the 500 Watt halogen lit up in there.
Also have a 100 watt incandescent bulb pushing heat next to the second bag.
wish i would have just used standard grocery bags lol
-
Thought my saw was a mess glad I dont have to clean yours . Happy cleaning

I wish I had standard grocery bags. Its seems bags are made tighter now, even Trader Joes' bags are slicker and therefore drain slower . . . so I recently bought pillow cases at the thrift store. I have not tried them yet, but please expect a report once the next saw cleanout is complete.

Why do any of you clean your large saws? I never empty any of my saws. I do continually use a plastic 1 quart container to scoop muck the front of the saw and a board to reach under the carriage and right up to the blade. I put a few quarts of the muck when it builds up a bit - into 5 gallon buckets and let the oil separate from the solids. I pour off the clean oil back into the saw. I have two saws and five buckets in use for settling. I never filter the oil. Rotate the buckets until the thickest muck is left in one bucket. I then pour and scrape the "clay" into small plastic trash bags - double them up and tape them closed. I then put the "clay/slurry" mix in with our trash which goes into a lined garbage dump site to never harm our environment.
I think a lot of you put too much "work" into this!

I usually do the same, i havent cleaned it like this since i purchased it.
I usually have a covered ship strainer willed with goo as well, i had alot of water in my saw and it was making oil leak out a tiy hole and onto my patio.
So, seeing that, i grabbed my goo bucket to put some into it and pour off the oil standing on top of the oil. made it two steps, maybe three to the front of the saw (on my patio) and the side of the bucket exploded from UV rays eating the plastic lol
I had wuite the serious mess and a VERY VERY unhappy woman.
So i spent the whole day scraping rock sludge into containers and vaccuming goo into another container connected to my Vac hose via smaller hoses
-
I just clean out enough that the oil stays oil, not sludge lol
-
I also didnt think double bagging the oil would make such a difference in time to drain through it.
But its taking A LONG TIME!
Oil only dropped an inch and its over 100 degrees in my saw with the lights heating it.
-
By the way - If you are a true business, try contacting local paint and building supply companies. Ask if they sell shingle or fence oil. Both of these are very light mineral oil and the solids separate from these two products fairly quickly.
I buy mine through a wholesale chemical supply company for about $3.00 a gallon above the cost of diesel fuel - under $30 a five gallon pail.
-
and i am buying horse laxative mineral oil for $25 a gallon.
I will have to look into this. I shouldnt need a business license for a purchase like that.
But i have friends with a business license just in case..
I would use hydraulic fluid, but i hate the stench it has.
-
Looks like the results of a lot of drinking and some deli-mart hot dogs.
-
this stuff is not draining through the charcoal bags, i may have to suction it all out again and replace the filter bags with grocery bags.

I buy horse laxative mineral oil light through them at $14/gallon, and shipping is free after $50. So I get my 4 gallons shipped free for $65.

For the lapidary shop at the local junior college, we use FGH-32 oil. Our club furnishes all the equipment, supplies and maintenance costs for the college. The oil - Food Grade Hydraulic oil 32 weight - is purchased at a local petroleum distributor for $14 a gallon. We pick it up at their location so there are no shipping costs.

We also pick up our saw oil from a local petroleum products supplier. They recently switched from the Duoprime 90 we used to buy to Finevestan 85. Both food-grade mineral oils, and the Finevestan was about $16/gallon.
If I recall the viscosity charts correctly, the Finevestan isn't quite as "thick" as the equine laxative. That's worth the price difference to me. The Finevestan really flows well - even in cold weather - with a generic swamp cooler pump.
Someone on here once said the veterinary oil is quite a bit thinner than the Wal-Mart mineral oil, but I tend to stick with what I know. I hope someday I can see some of the scahealth oil in person just to make the comparison for myself.
-
Walmart human laxative mineral oil is definitely thicker than equine laxative mineral oil. I've rarely used baby oil but my impression was that it was closer to equine mineral oil but with an odorant additive. My shop is unheated and gets to 40 in the winter until I fire up the wood stove, but the viscosity of the horse laxative is not a problem for my saws. I do not pump it but my impression is that it would still work with a swamp cooler style pump.
-
Thanks for that comparison from someone who has used both. Is the veterinary oil clear, or does it some color?

I have been using the Santa Cruz horse laxative oil for a couple of years now. Last week I cleaned up my 12" slab saw and I re-filled it with some rockhound oil I had filtered out of an old saw that had come through my shop.
I have been slabbing Wild Horse Owyhee Jasper.
The first thing I noticed was that the rockhound oil held a lot less cuttings than the mineral oil light. It stayed clear after several hours of slabbing.
The laxative oil always colors up fast. It would settle overnight but when I was cutting, the oil would cloud up and make it difficult to view the process through the window.
I also have the impression that the saw is not working quite as hard. Not sure of this. :dontknow:
I have been getting good life out of my blades with the mineral oil light.
Just a couple of observations.
-
Good to hear about the "rockhound oil". Any more specific name or info on it?
This is all good to know, since I mostly use Mr. Hoover's method of recyling oil. Always have buckets settling so I can just pump the oil off the top.
None of us look forward to cleaning out saws, and I'll let the drop saw build up a layer of clay in the pan. Scrape it out after getting the dirty oil off so I can put settled oil back in. Good to have more actual oil volume so it doesn't cloud up as fast.
-
so far, my oil recycling is going slow.
Dropped a good inch & a half since mucking the saw out.
Should have just used single layer bags....

I personally do not choose to pay for it. But I like it. :azn:

If you research MSDS documents for mineral oi, laxative oil, and Rockhound oil, you will find that Rockhound oil is nothing more than light mineral oil. Same for Walmart baby oil. Horse laxative on the other hand can be anything from heavy mineral oil to oil with trocopherol and up to 50% filler. It will be just as safe as light mineral oil but may not work as well in your saw depending on the source. Likewise shingle oil which goes by many names can be almost anything including linseed oil. Food safe hydraulic oil is another general class that can be nearly anything. For our use in sensitive machinery we used synthetic oil for that.

The site has a problem right now. Something about Failure of Web Server Bridge ??

Horse laxative may indeed vary depending on whose making it and . . . how much the person administering it loves the horse. However, ever bottle I've ever bought (mostly at the local feed store or Tractor Supply) also described the product as light mineral oil.
The first time I bought horse laxative, the vender was curious why I was buying several gallons when the normal dose for a horse was (if I recall correctly - a quart). I sheepishly told him I had a very large horse but quickly admitted to having a rock saw that needed gallons (not quarts).
Things must be slow when the process of cleaning a saw can prompt a thread lasting several days. Cheers.

Its a dirty topic, dirty topics usually go way farther and more in depth than clean topics lol
