Well thought I'd update this thread just in case somebody needs some info.

I've cut 12 plates of carbon 293x129x4 and done a few various parts from the plate.

Had a few trail and errors with cutters but found a cutter that works a treat and just 55p yes 55 pence, once they have done 1 plate they go in the bin.

DOC I've been doing was .5 mostly cutting 2mm WOC at 24k
