This is tentative: I've moved the subframe back to the origin of the grid
...
in its own model, although I haven't yet lifted it so that its wheel sits on
the ground plane. I've rescaled it so that the wheel is the correct size.
I think each individual model should be build to the grid origin within its own
file, but that major components (subframe, fourbar) should be at the correct
vertical height for final assembly.

I've written a hull which in itself isn't dreadful, but which has revealed
...
fragility in the way OpenSCAD handles name collisions. This makes mixing
libraries highly problematic. Needs thought.

Greatly improved pedal; both secondary chain sprockets in place.

A good enough for now, working, parameterised, four bar linkage. Pleased!

Start made on the four-bar linkage. I need to remember trigonometry.

And we have a model subframe which is really promising! OpenSCAD for the win!
