I am in the process of doing a test mixing antifreeze with the water that saturates my JET Slow Speed Grinder stone wheel. I keep getting email on this and nobody seems to know much about it though many are more than willing to theorize.

I decided to give it a whirl and right now my JET stone grinding wheel is saturated with a 50% mixture of water and Sierra brand antifreeze. This brand claims to be “safer” for people and animals yet shows remarkable freeze protection down to temperatures that really should be off of the woodworking scale of probability.

So far the wheel has been saturated and re saturated with the antifreeze/water solution and nothing has happened to the stone. It still grinds fine, hasn’t gone soft and despite being set directly in front of a hole in the garage door in my unheated shop, hasn’t been bothered by temperatures (measured at the grinding wheel) of 18-degrees so far.

If anyone has tried this and has first hand information I’d like to hear it! Email me at thintz@newwoodworker.com.

Might the chemical that makes the antifreeze effective react badly with the binding agents in the grindstones?

I’ve been updating the original story and it shows that even with re-saturating the wheel with the antifreeze solution, the stone has not softened or done anything that I can tell. It still sharpens the same and grades the same. Remember that this is all being done with a JET stone wheel. I have not tested any other manufacturers wheels. (and won’t, this one cost enough!)

Sounds like a plan, Tom. Good idea.

Here is a link to that story. I thought I had done this earlier but my age is hanging out again and I forgot, or something.

It’s hard to tell what the effects will be over months and years… A week is nothing.

A week was nothing but that was at least three weeks ago and I have been resaturating the stone every other day, sometimes everyday just to be sure it is alwayssoaked with the antifreeze solution. In a year I’d probably have the stone wore out anyway as much as I use it.

I’m curious as to how much gets thrown into the air… What does the MSDS have to say on the antifreeze ingredients?

Could you use the wind shiled cleaner that you use for your car?

Windshield cleaner is essentially methanol and water and some blue dye. As a result it evaporates rapidly so it wouldn’t work very good with a grindstone.

The stone will be fine in the antifreeze. A lot of manufacturers are switching from Ethylene Glycol to Propylene Glycol because it is less poisonous. Just one carbon longer…
Just like Methane (1 carbon) Ethane (2) Propane (3) or Methanol, ethanol, propanol

Regardless – the binding agents remaining in the stones are completely inorganic, There are usually also organic binders that are blended with the particles to make them stick together under the press, but then are burned off as the stones are sintered. Basically the same kind of process turning clay into ceramic/brick – the particles are sintered together.

If it is 18° in the shop, then its time to get a heater, or go do something else. Adapt the shop to the worker, not the worker & tools to the shop. :)

Just for grins when the last response was posted (WAY late!) I went out and checked the stone that has been saturated with the antifreeze ever since all this started. I put it in a sealed plastice bag ahen I got tired of saturating it every day and as of 10 minutes ago it is still nice and hard, just like before I started saturating it with the antifreeze. I’m thinking that it is going to be OK.

If it was automotive anti freeze it was highly toxic to pets if ingested. I would check that out if you have any pets that have access to the shop..

I have gotten tons of email on this topic over the years and finally decided to tri it out for myself. People say the stone will dissolve, it will gum up, it iwll quit sharpening, all sorts of stuff. None of it turned out to be true with the antifreeze I used. Rather than gfo through all of this again here I’ll pout a link to the sgtory below.
