found if your are simply sliding a tube within a tube - not much of a
problem.   My experience is when you have two tubes - each rigidly
constrained at it's end that you are trying to keep sliding, even a very
small amount of angular/axial? misalignment can cause the tubes to bind.
The longer the tubes the worst the problem.  Perhaps I don't understand just
how they moved the tubes and they may have had the same problem - but could
afford the precision machining to overcome the problem {:>).  I'll have to
go back and look.  But they did not use the EDDIE.
