Tools & Preparations:
These ships are built the same way the life-size versions were, some even have exactly the same number of planks! and as with any worthwhile project, perfection in the first steps is a must. There is a lot of cutting, shaping & sanding to these hardwood planks & parts, that can be done with any brand of moto or hand tools, it's just a matter of what you're best familiar with. My favourite moto-tool is a slim variable speed toy called the Octopus. And I don't know if it's still being made. If you do know of it, send me a link, I'd like to sell them.
The instructions are all written in millimeters, so a gauge or ruler of such will be needed.
The masts are usually straight dowels that will need to be cut to length and then sanded so they taper, rather slow by hand, but take extreme care if you're using a bench sander.
The hull planking strips will need to be cut to length and they're thick enough that a modeler's saw & miter box is real handy here. Some of the planks will also need to be tapered and shaped to fit the contour of the hull. A sanding stick is pretty handy here, and I keep a mini spokeshave if you prefer planing to sanding.
A Shipway or Keelworks Jig is a guide/clamp that holds the keel straight and keeps the bulkheads or ribs at the perfect 90 degree angle for glueing up the skeleton. And keeps everything straight as the glue dries and shrinks and tries to pull things out of line. This tool can be bought or is a good project for build your own if you like to play in your woodshop. I have designed my own version with the help of some of my ship building customers, available in two sizes finished, or the plans can be downloaded for cheap (as Mad Magazine use'ta say).
The Amati nail pusher is of great value in laying the planking because you can hold the skeleton in one hand and easily line up the tiny brass planking nail and push it part way in with the other. And a small hobby hammer to finish what the nail pusher started.
Building:
The keel is easy, it's usually one pre-cut and shaped piece of wood, notched for the ribs to fit into. So build your Keelworks Jig, line everything up and dry fit, and then get your carpenters to work setting the ribs.
When the ribs are set and dried, it's time to add the filler pieces that give a solid backing where the planking strips will have to curve sharply. Now the ribs and the fillers are filed and sanded to their proper contours, matching the changing curves in the shape of the hull, to give a good surface for applying the planking.
Laying the Deck:
The decks are usually solid pieces of plywood, and once they are set, there are decking strips supplied to laminate over the top of them. Usually the first deck piece will have notches cut into it that will match up and fit into the ribs of the hull. If your deck happens to have more than one level, each level is still done as described here.
Find and mark the centre line of the solid deck piece lengthwise, and put a few measured marks out from this line on each side to act as guides for the planking strips.
The planking strips are applied starting with the centre starboard strip first, set right at the centre line you've drawn, and then the matching port strip butted up tight to the starboard strip, and so on, slowly laminating out toward the sides of the ship.
Do not try to cut the planking strips to exact length- Start them at the bow and leave a tiny bit to overhang, and finish them at the stern the same way, overhanging just a bit, as it's much easier to file and smooth them down to fit the hull contour later than it is to try to cut an exact length in a strip that will be curving as it goes along.
When the deck planking is laid, the tiny bits of overhang can be cut off with a small saw or very carefully! with a shear, and then sanded down to a finish, or just sanded from start to finish.
Hull Planking:
This planking is always applied from bow to stern (front to back), and this is really important- You must work both sides of the hull evenly, as in- Apply your first planking strip to the starboard (right) side and then lay a matching strip on the port (left) side before going to the second strip. To lay planking on one entire side first and then the other would pull and twist your hull completely out of shape, and this would not be pretty!
The planking strips will typically have to tapered at the bow in order to bend and fit properly as the go they length, dry fitting these strips may have to be done many times to get them right. On a double planked ship, the second layer fitting perfectly is obviously critical to the finished appearance, especially if your ship is to have a natural walnut finish.
The planking is tacked at the bow end with a Zap-a-Gap type glue & one of the little brass nails supplied with the kit, and then the length of the strip is laminated to the bulkhead frame with a yellow carpenter's type wood glue & the brass nails.
