Progress on the #tricycle project is mainly in thinking about and working on the subframe. One thing that I'm sure is the right decision is to give the subframe a flat mounting flange, which will bolt down onto a matching pedestal within the hull. This will make the subframe easier to fabricate, and easier to mount/dismount - which I think will be needed for any work on the wheel or tyre.

New Computer Aided Design rendering of the aluminium subframe, now with a flat mounting flange. It is a gangly collection of welded rectangular section aluminium extrusions, surrounding a wheel, a bicycle chainset with an enormous chain ring, and an epicyclic gearbox mounted in front of the chainset, and driving the wheel by way of a secondary chain. Both chains run on the left hand side of the drivetrain.
A Computer Aided Design rendering of a carbon fibre subframe laid up over an extruded polystyrene armature. It has an identically the same mounting flange to the aluminium design, except this one is laminated carbon, and it wraps identically the same mechanical parts in the same arrangement.

I made a poll to see what generation do programmers in the Fediverse belong. 1,184 of you participated, and this resulted in the following distribution:
82.88 of you reported being a Baby Boomer.
473.6 of you said you belong to Generation X.
532.8 of you said you are Millennials.
82.88 of you said you don't belong to any of these three.
I was surprised to see these many Generation Xers at 40%, vs Millenials at 45%.

Saturday night is film night, and today it's Absolute Beginners. I didn't see it when it came out, for no good reason. It should have a good soundtrack at least. #films
