This is video is bad. When the presenter asked Karl "Is there like any different considerations I got to make when cutting a carbon handlebar?" Karl missed the most important piece of advice and seems clueless about safety when working with carbon. Karl just increased his risk of lung cancer and by his lack of knowledge on safety, he also did it to the presenter and cameraman standing next to him. Not only is carbon dust damaging to your lungs, but the dust from the epoxy used to bind the fibers and form a solid structure is also toxic. When carbon dust gets in your lungs it lodges itself in the lung tissue and cannot be easily expelled out, the healthy tissue turns into scar tissue around it which is called fibrosis. It significantly increases your risk of lung cancer with repeated exposure. A one time exposure won't mean that you will end up with lung problems or cancer but its best to lower your risk by taking precautions. As someone who works in the aerospace industry with carbon parts, I'm telling you that safety when working with carbon is very important. At my workplace we have dedicated negative pressure carbon trim rooms with filters to clean the air before its pumped out of the building and the person doing any cutting or grinding wears a fully sealed hazmat suit with a dedicated air supply system. 1. Ideally, you're much better off cutting carbon outside your home .But whether you're doing it outdoors or indoors, you must always wear an N95 or higher grade particulate respirator on. Cutting it outdoors will make sure you don't have any free floating dust or dust settling in your workshop that can be kicked up again. 2. Do not use a vacuum cleaner as suggested in this video because you need high quality HEPA filters and exhaust HEPA filters to collect finer carbon dust. Without it, not only you might spread finer carbon dust everywhere from the exhaust, but carbon dust can damage the motor too since its conductive and most motors are vented to prevent overheating. 3. Always wear a pair of thicker nitrile gloves or double gloves on if one is too fine, because very fine carbon splinters can get in your skin, and that is not a good feeling. 4. My suggestion is to use shaving foam on area where the blade is cutting to contain any dust that is created.
I just cut my new raceface NextR bars with parktools saw cutter. Very clean cut
At home I use a pipe cutters for the few bars that I cut. I haven't used mine in five years. I'm old fashioned and don't trust carbon fiber bars
