Started repairing the cracked wing mast, Thought I would get it out of the way before starting the foam/fiberglass one.
Cut a strip out of the mast from hound to foot and then bonded a web 18mmx80mm inside the mast from hound to foot.
Next a Layer a 60mm wide carbon tape in the thickest area of the mast from top to bottom, then added another layer of glass from the hound to the mast base this will be followed with another layer of glass over the entire mast.
I hope that it will be OK now.
