<DIV><FONT face=Arial size=2>I've cut a lot of CF with my dremel. The
specialty hardware store here (Elliots) has 2" and 3" abrasive disks with
compositions for cutting metal, fiberglass, etc. These larger disks have a
very high speed at the cutting surface and they keep your hands above the part
to make a nice perpendicular line. I get the composition for
metal. Even longer cuts are not much of a problem. Same goes for the
laminates. Cut through the carbon, then cut on a bandsaw.</FONT></DIV>

<DIV><FONT face=Arial size=2>This doesn't sound like something one would find
at the local hardware store. Where can these blades be found?</FONT></DIV>

<DIV><FONT face=Arial size=2>BTW, what if you have aircraft ply laminated with
carbon fiber? I would think in this case one would need a blade with
teeth.</FONT></DIV>

face=sans-serif size=2>The proper bandsaw blade for composites does not have
any teeth on it at all. The blade consists of a coating of tungsten
carbide bits like rough sandpaper grit adhered to the leading edge of the
band. The blade cuts by abrasion and will break before it wears out. Any
blade with teeth is bad for composites as it will dull and the teeth can
grab and delaminate the sustrate or your bond to the
honeycomb.<BR></FONT><BR><FONT face=sans-serif size=2><BR><BR><BR>Gray
