I have a wet saw for all tile and brick work also has a square to cut pin straight ,I wonder if you can cut the carbon shafts with a wet saw?
I only need to cut 6 shafts
I've cut em with a dry saw with a diamond blade in it that I use for tile work and it worked. I would think a wet saw would be better. If you've got an old arrow give it a shot and see what happens.
