Keep peeling until you reach the was paper.
Be careful NOT TO SCRATCH THE MANDREL!
When you reach the waxed paper you can peel away the final wrap of masking tape. Do this to both ends of the mandrel.
Stand the mandrel on a bench, grasp the lamination, and pull down. The laminated tube should easily slide down the mandrel.
Slide the mandrel out.
Be very careful not to drop or damage the mandrel.
Reach into the end of the tube and carefully and slowly pull out the waxed paper.
If you pull slowly, the waxed paper will spiral twist completely out.
If the paper begins to tear, stop and try from the other end.
Next you will pull out the plastic stretch wrap.
Very carefully and slowly pull the stretch wrap out. Do not break the wrap. If it begins to break you may need to pull from the other end of the tube.
Discard all the scraps and place your finished tube somewhere warm and dry to completely cure.
Once completely cured, you can sand off any bumps, lumps, or sharp stray glass fibers.
A light hand sanding may be all that is needed.
The tube can be cut on the band saw to fit onto your completed paddle blade.
Cut the other end square. This will be the center of the completed kayak paddle.
The shaft should tightly slide onto the paddle blade. Sand, grind, file, as necessary to rough the mating surfaces and to fit them together.
The shaft can be glued onto the completed blade with Polyurethane glue.
