Forms locked in place.

The central spacers were modified and Wedges cut.  End forms were screwed to the strongback to stop them moving when the wedges are inserted. Once all prepared the wedges were inserted to lock it all in place.

 

The forms were then masked in prep for hot glue attachment of the strips. The whole thing was flipped over so that the hull could be stripped.

Once flipped the level was checked with a laser level.  Some forms required further alignment.
