I used to make my own; took installation-cable housing, don’t know the proper english word for it, you know that flexible, threaded polymer tubing, inside of which I stuffed 6-7 1.5mm twisted steel thread. Filled it up with silicone. Worked very well, quite strong and flexible.
Hopefully not. I’m thinking of trying it with maybe 3/4" latex or clear poly flexible tube with some heavy wire in the middle. I think I could fill in what’s left with a tube or two of caulk if I can get it in there. I know there’s also the mix yourself latex that is used to create forms. I’d probably have to order it but it does appear to be more liquid and could probably be poured into the tube.
Great idea! How did you fill it with silicone? I’m thinking of a silicone caulk gun but I want mine to be 3-4 feet long. I’m not sure a caulk gun would push it through the tube that far.
I did indeed use a caulk gun. I never needed that kind of length, but if you stand on a chair and get a buddy to straighten the tube, gravity should do the rest just fine. If you clog it you can just push it down with a rod. I forget how long it needs to rest, I seem to recall leaving it for two days before use (i.e. in with the silicone, in with the twisted steel wires, then let it harden).
