Help!
Quick q: how do you cut carbon strips?

Any tips? If I had a bandsaw, I'd use that, but alas I do not.

Hacksaw? Knife?

Tips for a clean cut?

Thanks.

Definitely not a knife, you will split the fibers. Best thing is a cutoff wheel on a dremel or a razor saw. Standard hacksaw blades are often to rough.

As always, wear a proper mask. Carbon dust is worse then almost any other type of dust. So play safe.

Wrap the cut area in masking tape,makes a cleaner cut.Razor saw cuts well,doesn't raise as much dust.

So doesn't seem to be a good way with hand tools?

On carbon fiber strips I had good luck with wire cutters, but I use a cut off wheel for tubes and solid rods.

Razor saw over a wet paper towel to catch the dust. Nasty stuff, not to be trifled with.

Carbon tube can be cut neatly using a tubing cutter, which doesn't make anything like as much dust.

I use a Master Airscrew Balsa Stripper as some unidirectional carbon fiber isn't really perfectly unidirectional. So if you start to strip a piece and pull full length as in the link above it'll change width.

So I run this stripper once or twice down the carbon fiber, then carefully pull it apart and take a pair of scissors and cut the strands that weren't unidirectional.

I tried a bandsaw with a metal cutting blade. It rounded off the teeth in a matter of seconds making the blade useless. Much like a grinder on the teeth. I use a mini hacksaw.
