Problem with cable controlled puppet build - looking for advice
I am completing a 3 foot long 13 cable worm-like monster as a cable controlled puppet for an 80s creature short film I am making in February. We cast a core that was fiberglass with a chopped strand re-inforced inner core which we have sectioned into discs and are using for segments around a central spine (see image) I am using Flanders Throttle Conduit 610-0330 for the cable conduit and 1/16th inch stainless 7X7 wire.
It is working great to articulate the tail, but my problem is that the conduit is too stiff to allow the first stage of front half of the creature to move freely as it goes through the core and terminates at the final segment or Neck of the creature. I am wondering if anyone has suggestions for more flexible conduit/cable(kevlar line) combinations that would work on this build to allow control of the last head segment but be flexible enough to let the 3 front sections articulate.
I need to grind out more of the segments to give any conduit running through there more freedom of movement but even if the segments were completely hollow the conduit would still prove too stiff. I think keeping the inner conduits as close to the spine as possible will also help the first stage articulate but I'm new to this so I'm in a bit over my head
