Re: G10 (cutting a disk)



I use a diamond grit blade to cut glass composites.  They run about $60 for
a standard circular saw size.  I am sure they must be available for a
handheld jig/saber saw (and would be cheaper than the circular saw blade).

You can use a standard saw blade, but... I'd get a cheap blade and then
throw it away when you are done, because it WILL be dull. Glass is hard, and
the blade goes dull almost instantly.  Fortunately, what you are cutting is
fairly soft plastic, and fairly brittle glass, so a dull blade actually cuts
reasonably well (if cooled).  The blade is worthless for anything else
though.

I don't know if lubricating/cooling the blade helps with the dulling, but it
sure helps keep the polyester or epoxy from melting, and it helps keep the
glass dust down (which is a GOOD thing).  I am sure Robert Cressler will
have a bunch more info.
