    Adam - 	There is no inherent reason why you cannot use vegetable
    oils, per se. The difficulty is in what happens to the oil after a
    little use; it degrades somewhat, and starts turning to gum on the
    interior parts of the saw box. Rather than deal with this many
    lapidaries use food-grade hydraulic oil, others use the special
    antifreeze for recreational vehicles, yet others use water or a
    water/lubricant mix for trimming. While it was once common for folks
    to use motor oil, or a mix of motor oil and kerosene I've never seen
    it done in the last four decades. Even slab sawing doesn't get done
    with motor oil any longer. 	I hope that you can find a lubricant
    which does the job without too many hassles.
