3.
The steps should be gently sanded to ensure that they fit down flush onto both the forward capping rails and the
top of the bulwarks.
4.
The steps should also fit back, tight against the 'step' in the bulwark, and tight against the forward face of the
after capping rails. In order to achieve this it will be necessary to gradually remove material from the forward end
of the after capping rails.
When you are happy with the fit of the after capping rails and the capping rail steps they can be secured into position, together,
on the model. The upper sheer rail, as described in the note above, should also be fitted now.
The middle sheer rail is formed from 1.5x1.5mm walnut. It runs the full length of the hull, from flush against the stem to flush
against the forward face of the stern fascia and is positioned as follows:
1.
The bottom face of the sheer rail is flush to the bottom edge of the forward capping rail.
2.
As with the forward capping rail, the sheer rail forms a continuation (outboard) of the top lining of the gunports.
3.
At the point of the capping rail step, where the forward capping rail terminates, the sheer rail continues aft,
parallel to the 1.5x1.5mm upper sheer rail above, i.e. parallel to the after capping rail.
Note: Do not be tempted to fit the lower sheer rail, this is intersected by the channels
channels at a later stage.
All of the capping rails and sheer rails are to be painted dull black at a time of your choosing.
The cabin roof support bulkhead (14) can now be secured in place in the keel – it is vital that this is fitted vertically as well as
level athwartships to avoid deforming the shape of the cabin roof.
Referring to
Plan Sheet 2, 'Captain's Cabin Roof
inner bulwark behind the captain's cabin screen and also tight against the underside of the capping rail. With this scrap
material in place it will protrude a distance of approximately 2mm beyond the inboard edge of the after capping rail. A length
of 2x3mm walnut should be secured to the top of the 5mm wide scrap material, orientated 3mm wide and 2mm high. This will
form a recess of 1mm to the top inboard face of the after capping rail.
Note: This strip of 2x3mm walnut should run the entire length, from the after face of the captain's cabin screen to the forward
face of the stern fascia. This strip forms a seating against which the cabin roof planking will finish and allows the top face of
the planking to form a flush finish with the top face of the after capping rail.
This next step is probably the most important, in order to attain as good a final result for the roof planking as possible, and as
such great care should be exercised. The width of the hull should be measured athwartships at the positions of the captain's
cabin screen, the cabin roof support bulkhead and the stern fascia. With these measurements in hand it is necessary to mark the
centreline onto the captain's cabin screen, cabin roof support bulkhead and stern fascia, in order to receive the first planks of
the cabin roof.
The cabin roof planking is from 1x4mm walnut. The first two planks to be laid should run from flush against the forward face
of the stern fascia (the ends of the planks should be bevelled to form a tight fit) (Photo 031) and extend forward, 2mm beyond
the forward face of the captains cabin screen. These two planks should be positioned one either side of the centreline
previously marked on the stern fascia, cabin roof support bulkhead and captain's cabin screen.
Note: All of the cabin roof planks should be seated down onto the top surface of the transom cabin roof support, the cabin roof
support bulkhead and the captain's cabin screen and as such some light bevelling of these surfaces will be required – while still
maintaining their individual cambers. A steel rule, or similar, can be held fore-and-aft along each plank to check for high/low
spots and the bevelling should be adjusted accordingly.
Note: Referring to
Plan Sheet 2, 'Cabin Roof
do not splay out to follow the angle of the ship's sides.
When fitting the cabin planks in place you may find it of benefit to glue some scrap material to the underside of the previous
plank laid, offset in order to form a ledge on which the adjoining plank can be supported.
As you lay each plank they should be individually trimmed at their forward edge, to terminate 2mm beyond the captain's cabin
screen. It is best to trim each plank as it is laid rather than trimming them all upon completion.
As you work outward from the centreline to the ship's side the outer planks will no longer extend aft to the stern fascia, instead
they are to be trimmed and shaped to terminate flush against the inboard face of the after capping rails and onto the recess
previously formed.
