Fair­inG chine strinGers

For the chine panels to at­tach prop­erly, the up­per and lower chine stringers need to present a flat sur­face. As in­stalled, there were some vari­a­tions. The an­gle was gen­er­ally correct at each frame, but in be­tween there were some ar­eas where the stringers hadn’t taken up the correct twist or an­gle.

To rec­tify this, we took out the long planes again. Us­ing the plane bed as a straight edge showed us how much needed to be planed off in each area, and a few strokes with a very sharp blade soon trimmed each stringer suf­fi­ciently that a bat­ten could lie flat across both sur­faces. This took some time, with con­stant mea­sure­ments to en­sure that port and star­board chines would be the same size.

Next up came the tran­som. This will even­tu­ally have a nice tim­ber ve­neer at­tached, but at this point the chine and bottom panels will sit over the top of the ply­wood tran­som. To en­sure it fit­ted, we used long planes to plane off the edges to a feather-edge bevel that would then ac­cept the ply panels, glued on top.
