Starting on the crane...

Slower progress today as work begins on the pneumatic crane.

My daughter took a look at the main chassis:

Me: Look it has powered outriggers, and the motor tilts the body when I flip this switch!

Rachel: Uh huh...

Me: And look it has these differentials, that...

Rachel (stiffling yawn): So... is that all it does?

Her mother has trained her well.
