Eddy not so sure water jet is such a good idea I was going to cut my carbon in a water bath until I said this to the people that manufactured the carbon for me, they warned me against that as water can get into the carbon through the edges thus lowering the strength of the carbon.
they cut with a Cnc and an industrial dust extraction system, I will be doing similar but with the Cnc in an enclosure with a vacuum cleaner for the dust extraction.
