Assembly of Masts and Mast Tops.
•
Fit the mast ends through the assembled tops and into the mast caps, joining the lower mast,
topmast and topgallant mast sections. Before the glue has set, check that the mast parts align
correctly.
•
Fit the support cheeks made from plywood parts 61F, 62F and 63F respectively to the sides of
the two mast sets. Glue the tressle-trees down onto the support cheeks, checking that the tops
line up correctly with the fore and aft line of the mast.
•
Tie reinforcing rope around each mast in the four positions shown, and secure with glue.
•
Trial-fit the masts into the deck and make adjustments to the deck holes as necessary to get a
perfect vertical alignment of all three masts as viewed from the stern. Use the scale side view
to align the masts with the positions on the drawing.
•
Remove the masts and slide the base of each mast into the appropriate mast fife rail (part 65
and 66) and then the appropriate mast foot (plywood parts 67 and 68). Glue the masts in
place, using small wedges if necessary to ensure that the masts and tops align with the centre-
line of the ship. Glue the mast feet in place. Glue the mast fife rail in place on each mast.
•
Varnish the mast assemblies and the yards.
Figure 14 – Gaff and Boom fixings. Fit the jaws (plywood parts 64) into slots cut in the end of
the gaff and the boom. Reinforce each structure with a length of ∅0.25 rope
Figure 15. Chain-plates item 70. Gently roll the ∅0.5 brass wire around the ∅5 dead-eyes (item
A) and make a small loop in the other end using round-nosed pliers, checking the correct length
against the scale side-view. Insert the wire into the channel slots (parts 35-36) and secure the
chain-plates to the hull with brass nails. Drill and fit the chain-plate securing strips (item38 figure
13, sheet N° 1 made previously) to the channels with glue and brass nails.
Bowsprit. Assemble the two bowsprit sections into the bowsprit cap (plywood part 61E shaped as
shown on the scale side view). Chamfer the end of the outrigger to fit it snugly against the upper
bowsprit, and fix it to the cap using glue and two brass nails. Glue the bowsprit in place and lash
(gammon) it to the ram with rope as shown in the side-view.
Belaying pins. Glue a belaying pin (supplied in the kit) into each of the belaying pin holes drilled
previously, using a small drop of instant glue.
Rigging
Before securing the yards to the mast, it is advisable to tie all the necessary blocks to the masts
and the yards, for both the running rigging shown on Plan 2 and for the sail rigging on Plan 3.
Figure 16 - Materials for the Rigging. The diagram F.16 to the left of the plan shows how to
secure ropes to blocks.
are readily distinguished by differences in outlines in the scale side-view drawing and in
the key F.16 on the left of the plan:
A = 3 mm single-eye block
B = 3 mm double-eye block
C = 5 mm double-eye block
D = ∅0.25 mm rope
E = ∅0.50 mm rope
The recommended sequence for rigging is to follow the small numbers (from 1 to 53 shown on the
side-view) starting with the mainmast lower shroud lines numbers 1, 2 and 3.
take you first through the fixed rigging (used to tension the masts), and then through the running
rigging (used to attach the yards to the masts and to raise and lower them). The terminal points are
shown on the plan-view and side-view.
therefore needs two terminal points – one on each side of the ship. Apply glue to stiffen the tips of
the lines to help insertion through block holes and deadeyes. Ensure that rigging is tight, but does
not deform masts or spars.
Figure P.1 – Lower Shroud lines. Make these from medium thread and secure them to the masts
by using a seized loop as shown in the diagram on the right-hand-side of Plan 2. (Note that the
diagram P.1 in the centre of the plan is incorrect and should show the platform in place and
deadeyes connecting the upper shrouds to the lower shroud lines). The shroud lines are secured
around the mast, above the tressle trees (shown in the second figure P.1 on the plan), are passed
down through the gaps in the tops and are then tied off to the deadeyes.
