[TowerTalk] collapsing steppIR elements

[Jim Jarvis]

Interesting idea, to attach the tape to the tips of
the nesting fiberglass tubes.  Couple of problems with that, though.

First, it wouldn't be as well weather sealed.  Second,
although the telescoping fiberglass WOULD go in and out,
it's shaped and surfaced to grip when it's all the way out. 
That would need to be changed.

Finally, 'homing' the steppIR motor would require a non-zero
definition, and some way to index at the inboard stop.
