Re: Slab saw Lubricate
I consider the use of kerosene as a lubricant in slabs saws to be a bad idea.
While I don't personally know of any instances of kerosene ignition in a slab saw, I have definitely observed rocks sparking while being cut with a diamond blade. Agate and other chalcedonies are particularly prone to spark due to their quartz composition.
Kerosene is a flammable liquid after all, and I value my loved ones, house and possessions too much to risk it despite whatever advantages kerosene might offer as a saw lubricant.
Even if it is impossible to ignite kerosene in a slab saw, I certainly don't want to breath kerosene vapor.
Before you decide to employ kerosene as a lubricant in your slab saw(s), you may want to review some safety literature regarding its toxicity, especially if you are cutting inside an enclosed shop. Here's a couple of links:
I did production slabbing for some years and have breathed more than my share of (mineral) oil mist as a consequence, in spite of hoods on the saws and aggressive ventilation in the saw room while the saws were running.
Nowadays, I run water in my trim saws. My larger, mineral oil lubricated slab saws are on wheels and they run outside.
