Exactly the issue I was having. Not so bad making them on aluminum tube as the mandrel but this go around they were made on a CF wing tube. First try was putting 2 layers of packing tape on the mandrel and waxing. I had to split the tube to get it off. Next I wrapped the mandrel with 2 mil plastic painters tarp material, did the lay up and then spiral wrapped the works with more 2 mil plastic. It was rather easy to get the sleeves off the mandrel this time but I'm not completely happy with the exterior finish. Next run through I will spiral wrap with peel ply and then bag.

I did cut the sleeves to length and then cut some root ribs and ribs and sleeve supports out of some fiberglass skinned Diviycell.
