Guns, carriages and carronades in scale

The armament took nearly a year, and most of that sits in the carriages. The brass barrels were degreased and chemically blackened rather than painted, the axles were sunk so the gun does not sit too high in the port, and the bolts and breeching rings were made from the nails in the box.

The ropework is part of it too: breeching ropes of 1 mm cable-laid rope, gun tackles with 2.3 mm blocks, and a seizing of 0.1 mm silk thread round the small block, because a glued knot at this scale is bigger than the block itself. On the gun deck the fall lies coiled on the deck, on the upper deck it is frapped to the tackle. If you want it done differently: Piet (pietsan) strops his blocks with a single half hitch tight against the block, a drop of CA, the end cut off and the knot squeezed flat, and coils his deck rope on a piece of tape (Dutch forum, ‘Vaardigheden, tips en weetjes’, January and February 2020). The how-tos for that ropework are collected on the page Ropework and knots.

How-tos (7)

6 steps Lowering the gun in the port by setting the axletrees deeper
Put a trial gun in the port, and set the axletrees deeper into the gun carriage so that the barrel sits at the right height in the port.
5 steps Blackening brass gun barrels with blackening solution
Degrease the 28 brass barrels and soak them in blackening solution in a few rounds, rinsing and dabbing dry in between, until they are dark; the result varies from barrel to barrel and that is fine.
6 steps Detailing a kit gun carriage with bolts, linchpins, quoin handle and breeching ring
Upgrade the kit carriage with round-headed brass nails, simulated bolts made from the kit nails, linchpins from flattened nails, a turned handle on the quoin and a breeching ring from 0.7 mm wire.
5 steps Turning the quoin handle from a satay skewer
Chuck a satay skewer in a mini drill and turn it into a handle of about 4 x 1.7 mm with small turning tools and sandpaper, because turning from a square walnut strip went wrong too often.
7 steps Milling gun carriages for the 9-pounders on the cross-slide table
Mill the cheeks of scratch-built gun carriages as a stepped profile from a block of Castello boxwood, saw them into 2 mm strips and assemble them with axletrees and pins after Anatomy of the Ship, replacing the veneered kit carriages.
5 steps Making washers and linchpins from brass pin heads
Imitate the washers behind the bolts of the gun carriages by filing the round head of a brass pin flat in the lathe, and make the linchpins from the same pins.
6 steps Carronades: trucks from brass tube and a working elevating screw
Replace the white metal 'trucks' from the kit with trucks made from brass tubes slid into one another on a 1 mm axle, and the elevating screw with a 1.2 mm bolt that cuts its own thread in the soft white metal.

Problems you run into here (8)

ProblemFix
Gunports
Aft, the upper deck sits up to 4 mm too high relative to the ports; with the port linings in, the gun amidships no longer fits in the port.
The gun turned out to fit when turned round (the hole is off-centre); set the axletrees deeper into the carriage so it drops 1.5 mm; the top of the barrel at half the port height is right.
in the register
Gun deck guns
After identical treatment with blackening solution the barrels are uneven in tone.
Left as is; 'in reality they will not all have had the same tone either'.
in the register
Gun deck carriages
The kit nails are ugly (no proper head).
Received 6 mm round-head brass nails from pietsan for the visible parts; kit nails reused as bolts and linchpins.
in the register
Gun deck guns
The guns lack a ring at the breech for the breeching.
Rings of 0.7 mm wire wound round round-nose pliers, later cut into half circles; tip: wind the wire round a drill bit.
in the register
9-pounder carriages
The kit carriages are veneered walnut and not crisp enough.
Scratch-built in Castello boxwood, milled on a cross-slide table.
in the register
9-pounder carriages
Milling the first block, the steps came out too deep and the proportions were wrong.
Started again with the necessary precision.
in the register
9-pounder carriages
Because of the higher front axletree the carriage tilts backwards.
Left as is; on the deck the gun should sit roughly horizontal.
in the register
Carronades
For the carronade trucks the kit contains a white-metal blob, not real trucks.
Trucks made from two brass tubes (2.4 mm) slid into each other on a 1 mm axle.
