I have made a CF tube on a steel tube. I used the grease and tape method so that it will slide off but for the life of me I cant get this beautiful CF tube off the mandrel.
I have read that dry ice down the tube may provide enough thermal shrinkage on the steel to allow it to come off but just checking to see if anyone has any better ideas.
The first one i made came off but it was only about 5' in length, this one is 80", it has moved about a foot but seems to be really stuck now!

The men were amazed, and said, "What kind of a man is this, that even the winds and the sea obey Him?" Matthew 8:27
