Slightly off the topic, but I put a home made coolant system on my
old
surface grinder when I bought it about 7 9or 8 years ago. My
brother
told me how bad it smells around surface grinders because of the
rancid
coolant, so I went to an industrial lubricant company and asked if
anything could be done to avoid the smell. They sold me a 5 gallon
pail
of hi-tech coolant for $135. It gets diluted 32:1. There is NO
offensive smell, even though I leave the coolant in the tank for a
couple
of years at a time, only adding water to top it off until the level
of
sludge in the 15 gallon tank is 3 or 4 inches deep.
A good investment for me. I hope this can translate to your saw.

still have my 4 X 6 which I run dry).

I hate to say this after you bought the new stuff but for years we
used water and soluble oil for grinders. The water keeps things cool
and washes away the grindings while the oil keeps the rust under
control. Hardly ever smelled bad but when it did we just drained the
tank, flushed with water and refilled. Seems to me it was actually a
radiator additive and turned the water white like milk.

I'd rather have ice picks stuck in my eyes. I'm quite familiar with
it----and don't like it, not in any form, for any reason. The damned stuff
stinks (to me) even when it's not rancid, and is too sticky for
comfortable
use. Not just the machine-- I found my hands were sticky after using a
machine so equipped. While you may have worked where it was used in
grinders, it would be a dreadful choice, not only for its stickiness, but
grinding fluid should be quite thin, easy to see through, so picking up
surfaces isn't difficult. That's what was so extra good about Hocut
237.
Very pale, like weak lemonade. Nice fragrance when fresh, too.
There's nothing to compare with the chemical coolants, but they're not
cheap, and some, obviously, serve better than others. It's been more
than
20 years since coolant was an issue for me----I'm hoping to discover the
latest and best.

Maybe I wasn't explicate enough. We filled the coolant tank with water
and then added, maybe, a pint of water soluble oil. The result was a
sort of "white" water that had little if any smell and no oily or
sticky feel to it.
The intent was to use water as the coolant for the grinding wheel and
work with only enough soluble oil in it to prevent rust. Worked, at
least fir the several years I was in that shop.
That's a novel approach. My only experience with soluble oils revolves
around heavy concentrations, which I was powerless to control, being but an
employee in the shops in question.
Even Hocut was used in that fashion in all but the centerless grinder, where
lubrication for the blade was a requirement. The concept is certainly
worth exploration.
Thanks, Bruce.
