Given the fineness of your environment --the small material
and close tolerances, i.e.--, I can't imagine a knotted solution
to be adequate to your needs. Your use of those clamps looks
excellent, and I will suggest that you simply try to use them
better --to wit:
1) tension the line and set the clamps tight,
esp. the away screw (i.e., the one nearer the end);
2) bring the line back over the clamp body,
past the away screw --perhaps make a turn around it--,
and then
2b) loosen the near screw enough to turn the line
around its shaft,
then tighten it down on this turn!?
(Well, clearly I'm thinking that the screw head of this
bolt is of greater diameter than the screw body.)
I'd think that this would suffice to preclude slippage,
while allowing fine adjustment; maybe it allows the
screw tightness to be relaxed enough to avoid damage
to the line? (They look to be fairly kind clamps in this
regard; or could that be enhanced by some padding?)
One can muse about securing the lines to each other
or some part of the device (white plastic "X"s or the
center steel pole ...), but knots are prone to slippage
and yield under stress beyond what I'd think you get
in those clamps, and the risk of crimping the line by
knotting probably is as much a concern as whatever
damage the clamps do.
Another thought : can the ends of the lines simply be
brought back to turn around themselves between
clamp and abutting surface, as a lock against slippage?
Yes, that would entail inserting the 1mm diameter'd
material with effect on tension, et cetera (possibly
anticipated by lesser tightness in setting the clamps)!?
Admittedly, both of these wrap-the-cable-around-clamp
solutions risk bending the line over the clamp corners.
Maybe the simplest knotting solution is to turn the
lines around the white plastic *peninsulas* and then
tuck it beneath this turn (perhaps with a 2nd wrap &
tuck), sort of sheet bend, blackwell-hitch-like locking!?
(One need be chary of slippage from lack of sure nip
of a semi-flexible cord turning hard out of the hole
and over a flat surface (with wrapped tail to nip); a clamp
could be the finish, now needing less pressure for effect.)
