i've bought a carbon aeroscreen off ebay, but it's untrimmed.
i'm just wondering if anyone has any experience of using dremel type brown grit cutting wheels to cut wet lay carbon. i've used them for GF,
but not CF. i found a thread that recommends carbide grit edged saw blades, but with the convex shape, i think a jigsaw would probably end up
scratching something.
i dont want to bugger it up and have to buy another though, so would prefer actual experience rather than the usual myth and conjecture
do it right
or do it twice!
cheers in advance

I just used the bigger black GRP cut off discs in a dremel cutting 3mm thick (ish) wet lay CF
Went through it as easy as GRP.
Took my time though, as I do get carried away with the dremel

The carbide jigsaw blades work fine - just cover everything in masking tape to prevent scratching.
CF is easy to cut - much easier than GRP. It sands really easily too. A saw or a serated kitchen knife or anything will cut it but a fine toothed blade will give a nicer cut than a coarse one.
Cutting carbon composites is straight- forward enough with a disc or fine toothed sawblade, and the edges with sand easilt to a good finish.
The complecation is when they are reinforced with kevlar as this is tough and tends to give a fuzzy edge.
As with all composites, do wear a mask when cutting as the particles are really fine and can go deep into the lungs.
Where did you get it from tom? Was it a supplier, or just someone who had one?
Thanks
Its a good idea to cover up when cutting carbon, and as said above wear a mask.
If you use a dremel etc. with a thin cutting disc the dust given off is very fine. Dont know about everyone else but it gives me a rash where i come
in contact with it. Its also a bit itchy but not as bad as glass.
Usually when i cut it, i put a stip of masking tape down on the front / finish side, mark a line with a pen and cut using a small air grinder with a
thin cutting disc. Work slowly and you get a really good and straight finish.
Works well, but very dusty hence the above.
