How do you make a mold?
 

I have a couple of fiberglass lovers that pull air into the bilge that I would like to remake out of cf. what would be the easiest way of going about making a mold to make new ones, or would I be better off finding somebody to machine me a few based off of the ones I already have? I've looked around and they are hull specific so anyway I went would have to be custom made.

check youtube for videos. there are a bunch

Make a buck for what you want and pop a mold off it.
