Chain Boat
Brickvention (a Melbourne LEGO exhibition) kicked off today and this is my build for it this year. LEGO works well under compression so I thought I'd go for something a bit different and try a build mostly under tension. The chain boat is suspended from the top point of the mast and gets its shape from just hanging.
The 94cm (37in) 'C' frame was by far the biggest challenge in this build - my first attempt held the weight of the boat okay but I soon found that it also needed to be laterally rigid to pass the 'table bump test' for the exhibition. The boat acts as a large pendulum so any sideways sway would twist the frame and it would fall over. It went through several design iterations and I added the 'A' frame to the back for extra stability.
Happy to finally be able to share this one.
