Spiling Plank

A Spiling plank is a thin piece of ply or hdf which can conform to the stations where the planks will go. Measurements are written onto the spiling plank either side to the top and bottom of that face, and to the transom and stem. More measurements are needed to mark the stem and transoms line.

Battens were tacked on the stations in a similar manner to get the correct degree of bevel so that the spiling plank fits flat against it.

Here I am taking the measurements to the lofting floor. Nails in each point create a line which is faired as best as possible and cut. The card then taken back to the boat frame and checked before it is used as a pattern for the plank. The best layout of each plank is drawn onto the plywood and cut. This boats size was actually defined by the size of the plywood 2.4metres x 1.2m where the best use of the materials for cost is essential on a budget.
