Note: All unpainted areas of dowel for the masts and bowsprit should be stained walnut after shaping and prior to fitting.
Tapering:
You may find it easier to avoid turning the round dowel into an oval dowel when tapering, by using a David plane, draw knife
or similar as follows:
1.
Reduce the dowel (running with the grain), from a round at the start point of the taper to a square at the end of the
taper, of a diameter marginally more than that required.
2.
Repeat this process so that the dowel runs from round at the start of the taper to an eight side polygon at the end of
the taper, of a diameter marginally more than that required.
3.
Repeat step two as desired so that the dowel runs from a round at the start of the taper to a 16 or 32 side polygon at
the end, of a diameter marginally more than that required.
4.
Using medium sandpaper, followed by fine sandpaper the taper can be gently sanded round along its length.
Dowel Centring Jig:
The masts and yards for Badger should be made up in small sections which will be doweled together. This process greatly
simplifies the required tapering and shaping of each component.
The dowel centring jig (42) has been provided to enable you to accurately ascertain the centre of the dowel, this is critical
when drilling and doweling the components to one another. The jig is used as follows:
1.
Place the dowel centring jig onto the end of the dowel, with the profiled 'leg' of the jig resting on the end of the
dowel and push the dowel into the corner formed by the pair of non-profiled 'legs' (Photo 058).
2.
Mark a line across the end of the dowel, flush to the profiled 'leg' (Photo 059).
3.
Rotate the dowel and, ensuring it is still positioned as described in point 1 above, mark a second line across the
end of the dowel, again flush to the profiled 'leg' (Photo 060).
4.
The point at which the two lines intersect is the centre point of the dowel.
