No matter what sort of model boat kits you are working on,
make sure you set up a table that represents the number of bulkhead frames and
includes the transom as well. In order to decide the width of the plank at each
bulkhead frame, a dressmakers tape is supposed to be utilized with the
intention of calculating the distance between Plank 1 and the keel at each
bulkhead frame. Document these dimensions in the table.
For the Norfolk, the distance
between the keel and the Plank 1 at the mid-ship bulkhead frames is 88 mm. the
width of the plank is 5 mm. therefore, there’ll need to be 88/5 = 17.6 planks
to be fitted to cover the hull. Keep in mind that there’ll always be a small
amount to creep in plank width as you advance down the hull.
For the boat model you’re
building, apply the technique mentioned above to decide the number of planks
required. Then, making use of the dimensions you’ve made and noted in the
table, divide each by the number of planks to decide the plank width at each
bulkhead frame. Note down in the table.
From the dimensions for the
Norfolk, you’ll discover that roughly 1 mm will need to be tapered off the bow
and stern end of the planks. This is usual for a bluff bowed hull. Once more
for the Norfolk, you’ll discover the planks will need to be tapered from Point
A – where the plank begins to curve around the bow – previously recognized.
At the stern, the planks will
need to be tapered from a roughly ½ way between bulkhead frames 8 and 9. Each
of these points must be marked clearly on the planks – always prepare two
planks together. Make sure you keep away from forgetting to mark the planks as
previously described. Taper the two planks
collectively. In order to taper the planks, put them in a vice with the amount
to be taken off sitting proud of the vise jaws and position the marked point
sitting flush with the jaws. Make use of the mini plane and/or file in order to
get rid of the surplus timber.
Make sure you employ the same technique
for the entire planks to be prepared. Fit each plank under the previously
placed plank. Glue and pin in position.
The next point is vital: As you
advance with the planking down the hull, you’ll arrive at a point where the
plank doesn’t wish to lay flat. Compelling the plank into position will result
in it to twist and a gap will come into view between the bow block and the
plank.
Always keep in mind that for Norfolk, the
initial plank is attached in place 3.5 mm under the top of each bulkhead frame.
This is carried out in order to let a bulwark to be fitted soon after. It is
essential to check that the initial planks of the model boat kits are symmetrical and check that they are a replica
of one another at the stern and the bow.
