Vol. 65, No. 1 spring 2020 26 T e deck


17. T e Zona 37-320 spoke shave. T e overall width is about 3½ inches.


used to include them, and may still do so, but ZONA makes the identical tool (part number 37-320). I fi nd it gives me much better control for fi ne work than a full-size spokeshave and it was particularly useful in shaping the deck.


T e upper drawing in Figure 1 shows both the curve of the deck’s centerline and the sheer line; these two allow shaping of the deck. When I laid out these lines on the blank I allowed for the 1/16-inch thickness of the added deck planking. I assumed that the deck’s crown would be parts of circular arcs and I did not bother to calculate them. I just started shaping with my little spokeshave, which made quick work of it. To make sure the deck was symmetrical, I used a common contour gage, available in most good hardware stores. By setting it to a curve at one point across the deck and then reversing it end to end, symmetry problems are quickly revealed if a space appears under the gage. (Figure 18) I then applied the actual deck planking, using very tight grained cedar
