That because a Diamond blade (but not all!) with the very fine continuous
diamond mesh does not cut, it "sands". It sands its way right through your
tough iron meteorite and if your saw is running smoothly it will give your
slice a high polish as it finishes the cut. If you have some issues with
the straightness of the blade or continuous feed, etc. you may get grooves,
which is a sad problem!

Last time I cut with a diamond blade it only would cut the nail and not the
skin--wanna give it a try and see if thinner blades can cut skin?
Mike they make a slab holder/jig which comes in few sizes that lets you cut
down below 10mm or so. Once you clamp the stone in the jig you clamp it in
your saw vice. $20-30 on ebay.

Hi Listees and Stonecutters!
After using my saw on several occasions now, I wanted to
share a
recent experience and ask a related question.
While cutting a small unclassified NWA stone about the size
of a
walnut, my stepson showed up and started
watching. It made him
extremely nervous watching me handhold the small stone
while I cut it.
Apparently seeing my unprotected fingers a half-inch away
from a
spinning diamond blade was too much to bear. He is
absolutely
convinced I am going to cut a finger off. (Shows how
much confidence
he has in me!) LOL
He asked why I don't use some kind of jig or holder that
will hold the
stone for me. I showed him my rock vise, which is
made for use with
this particular saw. But the vise is only good for
larger stones, or
elongated stones. It's not much good for holding very
small
acorn-sized or walnut-sized stones. So, I bravely go
where no fingers
should go. He asked what I would do if I cut off my
finger, and I
nonchalantly said I would drive myself to the nearest
emergency room,
wait my turn, get it sewed back on, and then go home with a
big
bandaged hand and type a one-handed email to the list about
the
episode. ;)
So, my question is - how do you cut very small stones on a
6" lapidary
saw? Do you hand hold them? Do you use some
kind of jig? And how
many digits do you still have on your hands?
Honestly, I am not terribly worried about it. I am
experienced with
power tools and saws, so I'm not being reckless. But
if there is
something I can do to make my wife and family feel better
about it,
I'd do it.
Best regards,
10-Fingered Mike (for now)
