I need some advice. What would be the best way to make the below product out of carbon fiber? It needs to be perfectly round. I'm not sure you can make this perfectly round just using a dremel tool or something like it or am I missing something? Also, would you make this from a mould or would you make it off the back of this part? I think I prefer a mould but would like some other opinions. Also, should it be vacuum infused, or just wet lay up with vacuum bagging?
