The strength of the Menestrel's wing,lies within the dual laminated spar-caps,
The two spar booms are similar in construction to the leaf springs found on road vehicles,
For instance the top spar has a depth of 72mm over the centre section gradually reducing to just 6mm at the wing tip.
As you can see from the photo's the whole length of the spar is enclosed in a very strong diagonal ply shear web.
A very accurate and fully adjustable building table, similar to the design det ailed in the Building Tables Gallery photo's make's for easy spar fabrication.
