[meteorite-list] Another question for the Saw Wizards

[R N Hartman]

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.
