Just had a friend at work ask if it was possible to make a pen out of Carbon Fiber. I have no clue how Carbon Fiber even comes.(liquid, sheet, fabric, ect...)

Most knife making supply places carry carbon fiber.
Warning Carbon fiber dust is know to me very bad for you!!!!!!
Carbon fiber is available in tubes. I have a piece sold by the archery shop for arrow shafts. It is very stiff, and also the walls are very thin, which puts turning out of the question. I think it is about 5/16" outside diameter.
sad to say when I do a search I never get a result. Sorry I missed the post you made Rich nice looking pen BTW. Ok will let him know or just view this.
