It seems to me there is a way to make the segments folding so they could be
changed without removing and inserting boards. Kind of like a folding
ruler. I'll have to do some experiments with scraps of wood in my shop. On
a smaller scale of course.
When I was little I used to like forming letters and numbers with my dad's
folding ruler. I probably invented the 7 segment display without knowing
it.

Hi:
http://www.standard-time.com/index2_en.php
4 x 12 meter 7-segment display where the segments are boards held in
place by C-clamps. One man can change one segment, but it takes 11 men
and a couple of ladders to change two digits. If fewer (wo)men were
used the time to make a change would be longer than 1 minute and the
clock not be good to a minute. It looks like they started out using 4
bolts at each joint with power tools and later changed to multiple
C-clamps. You can buy a DVD movie that can be played on a PC where the
video is synchronized to the PC time. For more interesting On Line &
Hardware Clocks see:
