If you're able to do it the way described by coo2, then I would use a collet chuck because they hold the item all the way around the circumference, not just on three or four points like a scroll chuck. Select a collet that is slightly larger than the blank, wrap the blank with 2 or 3 layers of masking tape where the collet will be and slip the collet down over the masking tape. Guide the rod section through the head stock and carefully hand tighten the collet chuck. Then, secure the base of the handle/reel seat with the tail stock. You could use a live center with a small piece of scrap wood between the live center and the reel seat. Start the lathe on a very slow speed to make sure there is no wobble or vibration and sand slowly without applying too much pressure.
