[NSRCA-discussion] Cutting CF and FG Panels???

[Gray E Fowler]

While at work I find these blades on the machine. Somehow they magically 
show up. Where you would get them??? perhaps McMaster Carr

And what is you application that requires carbon fiber laminated on 
plywood?

This doesn't sound like something one would find at the local hardware 
store. Where can these blades be found?
 
BTW, what if you have aircraft ply laminated with carbon fiber? I would 
think in this case one would need a blade with teeth.

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.

What is the best blade to use on a band saw? It has 2 speeds, what is the 
best speed (1,450 / 3,000 rpm)?

I need to cut down two 12 x 24 panels and would like a clean edge ( 1/8” 
CF/Nomex/CF panel, and a FG/Nomex/FG panel) .

Nope, don't use the band saw much….

Thanks,
