simplest tentacle/hand Richard Landon cable mechanism basics

Adam Bradley

I bought some Nylon Tubing from McMaster Carr, and it doesn't move like Richard Landon gets his to move.  This that I have almost seems, brittle, like its going to stress break at the joints.  I don't see Nylon tubing at Home Depot.  I think what they have is Vinyl, which is too rubbery, and Polyethylene, which doesn't really spring back.  

Does anyone know where to get, and, well, WHAT to get, that has a good return like what is in the tutorial?

Thanks,

Adam

Hi Adam, Nylon is not UV resistant and gets more and more brittle the more sunlight you expose it to. You could have gotten a bad piece ( i like the black stuff at home depot for drip irrigation systems). you can also try Delrin/acetal tubing.

Thanks, I'll give the irrigation hose a try.  It looks like Grainger in town has nylon tubing, too.  I can pick it up from there another day.
