Handbrake
The final addition was the Handbrake
and its cables. The green handbrake
release button is sprung and can be
operated. The spring cord contains
an inner wire for "shape" but not
function. The real car's handbrake
cable was in two parts. 1] A rear
cable with adjusters at each end by
the wheels. 2] A primary stiffer cable
from the handbrake lever via the load
increasing linkage to the rear cable.
The mechanical advantage between handbrake
lever and the wheels of the real car
is around 10:1. I would have liked
to reproduce the linkage more precicely
but at this scale couldn't think of
any suitable Meccano parts, or how
to mount them. I was rather pleased
with my clear plastic plate handbrake
lever mounting.
