Cutting a carbon steerer tube?

yeah, just make sure it's sharp, obviously.
They use hacksaws in shops, but usually also use this guide tool to make sure the cut is straight. However, I've done plenty of my own at home with only a bit of tape to guide my cut.
In fact, I've even done a couple without even taking the fork off the bike 
Some people use some kinda tape to reduce the chance of the carbon fraying near the cut.
This tool kind of works like a guillotine, with the saw blade moving through the slot. The bottom bits goes in a vice, and the clamp at the top holds the steerer in place, but, as I said, I've done plenty at home without one.

You wil not have a problem with an ordinary blade, but finer is better. Just wrap some pvc tape around the tube over the postition you want to make the cut. Use another peice of tape to use as a guide around the circumference. Saw carefully through the first peice of tape and the tube using the edge of the second peice as the guide. Don't push the blade through, just let it do it's own work. No problem! Tape just stops any unsightly fraying of the carbon strands.rmwkokomo said:
I've used a cutting disc on my angle grinder. The high speed of the blade = less likelihood of the carbon splitting and less like hard work for me!

Same here - I cut a carbon seatpost tube with my dremel and a cutting wheel. I did wrap it with duct tape first, not to prevent splintering but for dust containment. You don't want that dust getting loose. Not good to breathe it in.
