After you cut it, is it okay to use a starnut?

I know some people use electric chop saws, but I have not actually seen it done nor do I know what type of blade is used.
- turn off the fan and close the windows around your cutting area.
- put some wet tissue under the cutting place of carbon tube to adsorb the carbon power.
- after cut the tube, use some wet tissue also to clean off the carbon power in/outside of the tube.
- finish !
Measure twice, cut once. Wrap the tube tightly with a bit of tape to prevent it from fraying. As others have advised, use the finest blade you can find. If it makes you feel better, you can use a cutting guide to ensure your cut I'd straight (you can also do it with a bench vise or freehand). Once you start to cut, use full strokes of the blade. Be careful, it will cut really fast. Only cut about halfway through, then complete the cut from the opposite side. Finish your cut with a fine file. I like to cut a very shallow bevel around the outside edge.
As others have noted, carbon dust is harmful to inhale. Do this outside if you can and wear a mask. If you push a rag down the steerer below where you will cut, then you will be able to pull it out after and you will not have carbon dust down the tube.

I made one from some headset spacers and duct tape, worked fine. You don't need anything fancy.
Dont want to highjack, but I need to cut my alloy steerer. How do I make sure I push the starnut furter inside the steerer to avoid cutting it while making sure it is still sitting straight in the steerer tube?
