Diagonal braces fitted |
Presumably, these braces originally helped spread the load from the weather beam to the cap circle, as well as stiffening the frame to resist thrust from the sails.
The cap is kept in position laterally by cast iron 'truck wheels' which rotate against the inside of the curb. Four of these were hung off diagonal struts running between the outside of the shears and the cap circle. We are having to remake these, as the originals had, you guessed it, decayed.
Making one of the new truck wheel supports (shown here upside down); lapped dovetail will fit into cap circle |
