7. Fairing the Hull:
Figure 5a:
This drawing shows the smooth transition from the bulkheads to bearding line. This transition needs to be smooth, free flowing and without severe curves. If the latter occurs a depression or bump will appear in the planked hull. Again something like this is most difficult to correct at a later date. So again take your time and look at this step carefully and from all directions. Run your fingers over the transition surface or lay a temporary batten along the bulkheads to check the alignment. It is important.
Figures 6 & 7:
This is the method used to actually fair the hull and to check the lie of the hull planks along the hulls bulkheads. Take a temporary batten, something in the order of say 5mm x 1.5mm. This temporary batten must be without weak areas and knots as this will affect the natural flow of the timber being used and will certainly give you a false or incorrect reading. Pin the batten at every bulkhead station. Pre drilling may be necessary to prevent splitting the bulkheads and batten. Any type of temporary fixing (planking screws are invaluable) can be used as long as the batten is held in constant contact with the bulkhead, if allowed to bulge away a false reading will result and the hull planking will be incorrect and almost impossible to correct later. Move the batten up and down the bulkheads as many times as possible, the more accuracy you obtain in this operation the better and smoother the finished hull is going to be.
Note: Planking screws can be obtained from many hobby stores and the authors fully recommend their usage.
