Cane arrows are very forgiving and generally fly well without much fuss. Start by getting them straight and they don't have to be all that straight to fly well.
I build cane and hardwood shoot arrows one at a time. Try that. Once straight taper the point end and add a field point and see if it spins true. I spin my arrows on the tip of my finger so I can feel any wabble. Being that the shaft is irregular an arrow spinner doesn't work well.
Next, find the stiff side of the shaft and set up the nock so the stiff side is against the bow. Now fletch it and shoot it. It should fly well or relatively so. If not, flip it over so the cock feather is in against the bow and shoot again. That should do it for you. If for some reason it still doesn't fly well, remove the fletch and add a spiral fluflu. It should work well for that!
