I do it all the time, but I use woodies.
Here is the "recipe": cut the arrow an inch after the fletching.
Put the fletched piece in the micro-wave, half a minute per piece.
Take the piece out and the glue will be melted.
Now you can pull off the feathers. Carefull: the piece might be hot.
If the feathers don't come off easily, put it back again in the macro-wave, otherwise you will ruin them.
You can also pull the nock off.
Put the feathers in a fletching clamp, and sandpaper the foot of the feather gently, till the old glue is removed.
There you go!I do it all the time and it is very easy.
I don't know if you can put carbons in the micro-wave.
