Default Best way to cut carbon fiber?

I want to play around with making my own CF top decks for my off road kits (Tebo is running them on all of his cars so I thought it would be fun to experiment with how they effect handling).

What is the best way to cleanly and precisely cut CF at home without expensive, hard-to-find tools?

Any tips on where to buy good CF would also be appreciated.

I would think a high speed jig saw with a fine tooth blade would do a decent job, it works for fiberglass. Just remember to wear some gloves and a dust mask, its quite sharp and you don't want to be breathing the dust.

Do you know which cut off wheel? And how do you cut a straight line with a handheld Dremel?

Get yourself a good set of dremel bits and cutoff wheels and go to town... I have cut out many parts and chassis out of graphite/carbon fiber over the years with this method. I some times will print out the shape on paper from a cad drawing and stick it to the plate so I have a template or draw it on paper first.

Make sure you wear a dust maks. I didn't years back and am sure it will kill me before it is all said and done... :-)

Good Luck...

Great idea! I'm just worried that hand-holding a Dremel will give me sloppy results.

interesting idea, I would say hand held tool will be hard to cut straight , tagging along to see other responses.

I if I do it I would find a cutter i had a guy cut a carbon chassis before , years ago,and made me some aluminum arms for 20 bucks.

Recently tried to do my own limo chassis and broke while running, found a guy who did it perfect for me, but I suck at things like that.

It cuts so easy that you can get it pretty close to straight and then just use a flat block with some 180 sandpaper to finish off a straight edge. If you sink the cutoff wheel all the way into the material up to the shaft, the wheel uses itself to track straight.

normally you can find local shops that do cnc / carbon work that will do small runs of different parts for decent prices if you want that super clean / professional look.

After you are done cutting which ever way you decide to go (I have done the cut off wheel rout before with good results) you can seal the edge with some CA glue to help protect the edges and your fingers

Default I'd have to 2nd what Toyoter91 said.....

I was looking for CF suppliers online and stumbled across a company called Dragon Plate. Not only do they sell CF products but offer a CNC service at supposedly reasonable prices (I have not used their CNC service yet).

I've cut CF before and it sucks. You don't want to breathe the dust and it's really messy.

McMaster Carr has CF plate.

For contoured jobs I use Fiberglast 3k 2x2 twill weave.
