Sounds like you didn't clean the shaft well enough. Glue is sticking to the vane, that would be the problem. Glue sticking to the vane, you did something wrong. Never wipe the fusion base!!! Scrub the shaft where the vanes are going to be placed with warm soapy water and a soft scrubber, rinse let air dry, and fletch. I would also use like bigbulls said, a better glue!
