Catheads:
(Photo 034) Identify and remove the catheads
0.5mm holes should be drilled vertically, top to bottom, through the outboard end of the cathead as shown.
One brass etched eyelet (167), painted matt (metal) black, is required for each cathead. Referring to
drill a 0.5mm hole vertically, up into the underside directly in the centre of the four holes drilled previously. This hole should
be drilled to a depth of no more than 3mm and the brass etch eyelet cut to length and secured.
The cathead should be dry fitted on the model bearing in mind the following points (Photo 035):
1.
The cathead is positioned centrally between the second and third timberheads.
2.
The base of the cathead (vertical section) will be raised 2mm off the deck, some reduction may be required.
3.
The underside of the cathead (horizontal section) will be seated down flush onto the forward capping rails.
4.
The cathead should be seated flush against the inner bulwark. In order to achieve this a 'notch' will need to be
filed in the inboard edge of the forward capping rail.
When you are happy with the fit of the catheads they should be removed.
Identify and remove the cathead brackets (128) from the 0.9mm brass etch sheet. These will need to be shaped as shown
(Photos 034, 035 & 036) in order to fit tightly around the cathead and flush against the inner bulwarks. The brackets should be
painted matt (metal) black at a time of your choosing.
Note: It is advisable to form the brackets around a scrap piece of 4mm material (or the spare cathead) in order not to damage
the catheads as they may be easily broken along the grain of the walnut.
When you are happy with the fit and shape of the cathead brackets they can be secured against the cathead, with their lower
edge 3mm from the bottom of the cathead.
The catheads, together with their brackets can now be secured in place onto the model. In order to add support to the cathead it
is advisable to drill a 0.65mm hole vertically, up into the underside of the cathead into the area that sits flush onto the capping
rails as shown (Photo 036). In a similar manner to the swivel gun pedestals, a dome head pin (183) can be secured into this
hole to enable the cathead to be pinned down onto the capping rail.
Note: Once fitted the catheads form delicate structures which can be easily 'knocked', as such you may wish to finally fit
them at a later stage.
