Yep - I think the only thing there is more
schematics of on the net is propeller clocks.

OK - They already have focus optics which
is good.  But what colour are they ?  I
thought they where shorter than 630nm.

1mW is pleanty for the comercial film if you
find a diode that doesnt do 70mW :D

Fine pitch brass bolt was my thought.  Not
a hardend and ground zero backlas ballnut :D

I used some stainless steel rope (from model
plain control wires) for something in the
past.  The multi-stranded-ness of it made
it easy to use.  It might be an idea again.
