Eveything went well & i wrapped the whole unit in clear packing wrap then vacuum bagged the whole unit.
The ridge from the sail track that can be seen here is good as a locator for the gooseneck on the mast.
Next job was to locate the pivot assembly. I used a 12mm diameter rod to align through the bush in line with the mast track. I cut a piece of 9mm foam as a spacer, then bogged the whole lot in place. Next job is to cover it with some more layers of carbon fibre.
