I normally hacksaw it outside - the dust isn't really a problem then.

Yeesh....I would never run a bandsaw blade backwards. I think KP11520 was talking about reversing a circular saw blade.

No wonder you had so much heat...

I've been thinking about this:

http://www.harborfreight.com/cpi/cta...emnumber=93211

It comes with a continuous rim diamond blade, which might not be a bad choice. I understand there are carbide tooth blades out there too for this size.

I just haven't been willing to spend the money to try it out.

Jeez, folks....
Most rotary blades will have a cutting speed thats too high - the laminate can get burnt.
A guillotine is the preferred method, without specialized eqpt.
Otherwise - use Pinkmouse's method - clean up with a file or a sanding block.
