There are different quality blades (quantity of diamonds per unit, in the
blade), and also various rim configurations. Performance varies with brand
also. I think the blade is wearing out when you are seeing less even cuts,
unless something is wearing in the saw itself. As I have experienced it,
the CBN blades are best and primarily for cutting irons.

Hi Ron and List,
I noticed that about the blade sanding it's way through the specimen.
The first slices I made were the smoothest and the prettiest. Now,
after many cuts, the blade is leaving more noticeable saw marks.
The blade I am using is the stock/default blade that came with the
saw, so I don't know how good it really is, quality-wise. I have
another blade sold specifically to cut meteorites, it's the same
thickness but the blade is brown-colored instead of reflective bare
metal. It's also a CBN, which comes highly recommended. I wanted to
practice with the stock blade before moving on to the CBN. I also
have an extremely thin and floppy diamond blade called a laser
"dia-cut" which I haven't used yet either.
Best regards,
MikeG

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)
