Builders Note

[SteveT44 <SteveT44-at-comcast.net>]

For those of you that have been following my progress in the development of
the Tyng Labs Mk1 track system and may be thinking of replicating it, a
quick note.

Since this track design is based on a spliced belt concept, once the track
is together, it is impossible to change it's length.  The correct length
measurement is critical.  The steps outlined in my construction photos for
measuring length have worked well BUT I did not foresee one element in the
track measurement that I should have.  I did not take into account, as much
as I should have, the amount of droop the track is experiencing.  Even when
fully tensioned the track has significant droop which looks great and is
very scale, but it has pulled T5's front idlers closer to the front road
wheel then I had intended.  This has reduced the amount of travel available
in the idler system and the small space between the idler and road wheel
could get clogged with debris.  To compensate I'm going to reduce the
diameter of the front idlers a small amount.  So the lessoned learned is,
simulate the full droop that a track can experience when measuring the
length for a Tyng Labs Mk1 track system.
