At this stage I can set the hull aside and continue work on the superstructure base which fits inside the deck aperture. If the base has been constructed properly it should fit inside the deck with a couple of millimetres clearance all round and be should be flush with the deck framework all around.
Two pieces of obeche strip were previously added to the insides of the deck aperture to support the framework at the front and rear making sure that the framework is still flush all round, if it’s not there might be a twist that needs to be corrected.
Fortunately my base was OK and so I just used my sanding plate on the base of the frame to take off any high spots.
The whole deck area was also sanded to remove any high spots too. Knowing that all was as it should be I glued and pinned the obeche strips in place. The 1.5mm ply inner deck skins were then glued and pinned to the framework all the while checking that the frame was still square. When the glue had set I trimmed the skins back to the frame leaving a very small overlap to allow for finer adjustment later after the deck skins have been added.
The deck skins were added next starting with the piece that covers the bow, but before fitting it I added some additional strips of obeche and balsa to add extra support to the bow skin, this is so that when I add deck fitting at a later stage they will be supported properly. Those extra bits were sanded to the correct curved profile of the deck using the sanding plate and the upper part of bulkhead B1 as a guide.
I fitted the skin at the bow first, followed by the rear deck. The deck side skins need some additional support strips of scrap obeche fitted in a couple of places before the skins were glued and pinned in place. After the glue had set I then trimmed all of the deck skins flush with the hull sides all round.
A small amount of trimming of all of the skins was required for the superstructure base to fit into the deck aperture and if all is well the skins should all be reasonably flush.
The cabin is assembled as a separate part that is fixed on top of the superstructure base. One of the cabin sides is laid flat and three cabin formers are fixed into it using the tabs and slots in all the parts and then the other side of the cabin former is attached.
This assembly was then glued and clamped together making sure that it was square and without any twist. Various additional formers were then added that form the engine room front face and other parts that form the cabin windscreen and rear door panel.
There appears to be another slight error in one of the windscreen formers that would prevent the windscreen panels sitting properly in the same plane so I re-made this part in new ply to make it to the correct angle, another item to bring SLEC’s attention to.
