Both #3 spars are now complete, with both hand being assembled and riveted.
RH Spar #3 nearing completion. Again, note the orange "reminder" tape. There is a lot to think about while assembling the spars and avoiding mistakes is a big part of this process!
RH Spar #3 components progressing. These have been built alongside the LH spar for efficiencies. At certain stages the LH spar leaps ahead with the RH playing catch-up!
An appropriate demonstration of the size of these #3 spars! Engineer Hadon is 6ft2in tall. Also worth noting is the width of the root end of the spar.
