Very Coarse Crystolon / Siox Stones Guzzling Up Oil?

[Patrick Chase]

Won't have to, now. The three stones are still soaking up oil......they were very dried out. I get them out of the "bath" in a bit, and towel them off. Then,....we'll see how they turned out.

One never knows. until one tries. Gets me up out of the chair, at any rate. I do have a couple other "dried out" stones.....maybe sometime I'll try the goop in the oven......might make the Pumpkin Bread smell a bit...funny, though

I don't doubt they'll soak oil up.

My concern is whether they'll retain it and/or retain new oil on their surfaces, which is after all the point of the exercise. If you're willing to store them in oil then you're GTG, though :-).

Stones are now out of the oil bath, and wiped down. Have them sitting out in the open air, and letting the Sun shine on them...

Waiting to see IF any oil oozes out, and how much. Need to make a box or three to hold these in. Hmmm....walnut, or Cherry?

It's interesting but not likely to stay put. Set the stone down on a block of wood and 90% will seep back out into the wood. There is no way the sun or even a hot oven will congealed motor oil to remain in the stone. Anyway, that's my Nostradamus thought of the day. If it turns out good I will buy you lunch next time I see you.

[steven c newman]

Mine Nostradamus thought for today.....At least I was willing to try it out. just came back in.....one small spot on the paper towel sitting under the three stones. I didn't have the middle one wiped down as well as I thought. So far, so good.

I MIGHT build an oilstone box, when my knee will let me work in the shop, again. The oil wood I set these on has a coat of finish in it, anyway......my bench. Rest of the time, they sit on a sheet of sandpaper, so they don't try to run off on me.

[steven c newman]

Stones are back in the house. Paper towel was barely a spot of oil on it. Stones even feel better, and a hair heavier. They also have a slight shine to them....

Will know more when the next sharpening day comes around. So far, so good.

mRI next Tuesday on the knee. Then see what they are going to do to fix it. Got the Tri-Care approval this morning for the work on the knee.

[Stewie Simpson]

Steven; appreciate the feedback on the use of the heavier grade oil. All the best with the knee surgery.

Stewie: Thank you...

Received a phone call from Rao; Petroleum Jelly/ Vaseline is not used as part of their oil fill process. He would not recommend its use, to resolve the issues outlined by the OP.

Might be a good thing I tried that oil soak experiment?

Stewie;

Did he say what *is* used?

[Stewie Simpson]

Patrick; that was mentioned during the discussion, but he emphasised that unless the process was tightly controlled, the results were likely to be unfavourable. He also covered the fact that; unless the stones mentioned by the OP were manufactured as non oil filled(specialised market for food preparation), that the oil fill should not dissipate under normal environmental conditions. Most likely the stones mentioned by the OP were either, non oil filled, or had been exposed to a solvent bath that had destroyed the oil fill. His recommendation to the OP was to not bother trying to resurrect the oil fill in those 2 stones, and to either consider purchasing new oil filled silicon carbide replacements, or take your chances at purchasing 2nd hand replacements.

I look forward to hearing more on Steven's experimenting with oil fill.

Stewie;

I am shocked, shocked that Norton would urge somebody to replace an old oilstone with a brand new one instead of trying to fix it.

Back when I was a designated "speaker to the trade press" I gave that sort of explanation ("it's a very tightly controlled process with super-secret steps that nobody else could replicate even if we told them how it works") more times than I can count. Sometimes I even managed to keep a straight face while I said it. Suffice it to say that I don't find it credible.

[Stewie Simpson]

Patrick; during my discussion with Rao there was no hint that he was trying to feed me a lot of baloney, in fact I found him to open and honest within all the questions I asked of him. I followed through with promise to source the information directly from the manufacturer, you rightly commended me for that action, but to then turn around and claim that Rao was feeding me the usual spin, is rather disappointing to hear. The information I provided came directly from the expert employed by the Company to oversee their process. I have fulfilled my obligation to the OP. Except or reject that information. That is the clear choice you have available.

regards Stewie;

IF I get the time tomorrow, and find a decent chisel to use for a test sharpening...I might set up a stone and see how well the 3in1 oil I use stay on top of the stone. Stones are right now stacked up, bottom one is sitting on some wet-or-dry sandpaper. I lifted the stack up a few hours ago...barely a smudge of oil.

Perhaps Patrick could try this experiment as well? He could use whatever brand motor oil he wishes. The one I used was on hand, for use in my lawnmower. Found out it took 30W instead. So the 10W40 was "extra". I left my stones IN the oil all day, making sure they stayed cover in at least a film. I even flipped them over a time or two. maybe Patrick could do a more "Controlled " set up? Well???
