This week the manuscript was updated, adding detail chassis drawings to bring it up to the same level as the build. Drawings were also added
for the front chassis tubes which will be fit-up tomorrow (every other Friday off, whoo hoo!) These tubes, the ones forward of the foot-space,
have reduced wall and diameter to serve as crush space.
At the rear, behind the main hoop, 1.5″ tubing is used but thinner wall. Between that and the small suspension tubes, the idea is that it becomes crush space for rear impacts. Worst case, it’ll let the drivetrain break free before the cage is compromised. That’s all theory of course – I can’t afford to submit a completed car for official crash testing!
