Awesome. I would like to be there for that.

With a bits-box fan behind?

Maybe a knock up a wooden downdraft extractor that the cutter sits on

Looking at the cutter, there is an off-centre coke-can sized hole in
the floor pan that the extractor could draw from.

 Can someone in the know get me the part number so I can source these?
