Sleigh assembly complete. The whole family came over for my birthday yesterday afternoon and I put them to work. The sub-frame I designed was essential for stability. Without it, the entire thing was dangerous. Now it's as solid as a rock. Hopefully we won't have to pull it apart again. Four people managed to lift it fully assembled. The second photo (my youngest and his girlfriend) is to give a sense of scale. Now I can start work on the dashboard.
