I need to move my outer MRP plate to a position where unfortunately the crank arm is in the way. To get aroung this I need to cut/file about 1cm x 4cm of the CF away. Basically I need to cut this sort of shape out of it: http://www.chainreactioncycles.com/Images/Models/Full/3334.jpg I'm sure I've read in the past that carbon fibre is nasty ****, carcinogenic and stuff? Ignoring that for the time being imstupid how easy is it to cut/file, can I just treat it as if it were metal, or do I need to be careful not to end up cracking it etc? Any tips/advice welcomed!
