The Chemlease release wax works great. So great it is not possible to attach a tape to a waxed surface. That is why I placed the inserts for the halyard out recesses prior to waxing. Unfortunately, this demonstrated quite clearly, unforeseen, the effectiveness of the release system. This is the mould after removing the mast part. The lack of gelcoat is unfortunately obvious and I have begun the mental preparations for repairs
The part itself was however removed without any signs of damage. A very good result, part weighing in at 6,6 kg including peel ply and untrimmed, total weight of mast so far 28,6 kg which makes the goal of <50kg seem acievable. We were very eager to see what the complete wing looks like, so I lowered the trailing half from the ceiling, put in the foam blanks for the center web and placed our latest creation on top. Ståle demonstrating his satisfaction (and serves as a scale):
Another view of the complete shape, lower part of the mast, that is. I got those "so what will happen when at the dock in a storm"- thoughts again. I guess time will show. I expect the mast to work very well as a Try sail.
This is a close up of the starboard halyard out recesses. Plan is to make a circular hole in the far end of the recesses. Halyards will be led to clutches and secured with horn cleats at the bottom of the mast. Snatch block on deck will temporarily lead halyards to cabin top winches.
