cf66 Posted April 16, 2022 Report Share Posted April 16, 2022 Hi all, Been trying to find out how to handle a long, hollow extruded tube to bend it into a coiled shape (think like a snake coiled up), without it collapsing. It seems it should have a soft fill inside to keep its shape but I can’t find the right material that’s pliable enough for this. Does anyone have any tips or techniques to do this? Thanks in advance.

Mark C. Posted April 16, 2022 Report Share Posted April 16, 2022 You could cap the ends and air would hold it-or wait till its firmer (the just right moisture point) to bend it. Thats what I have done in past-let it firm up a bit Link to comment Share on other sites More sharing options...
JohnnyK Posted April 17, 2022 Report Share Posted April 17, 2022 I know you can fill copper tubing with sand to keep it from collapsing while bending...You might try what Mark says, let it firm up a bit, cap one end, fill it with sand and then try to bend it. What diameter is the tube? Do you plan on glazing the inside? Link to comment Share on other sites More sharing options...
cf66 Posted April 17, 2022 Author Report Share Posted April 17, 2022 Sand! Hadn’t thought of that. Wonder what would happen in the kiln with the sand that gets stuck to the inside of the tube though? Trapped air though… hadn’t thought of that either, thanks guys, I’ll try and see what happens. Link to comment Share on other sites More sharing options...
Mark C. Posted April 17, 2022 Report Share Posted April 17, 2022 Use quaility silica sand from ceramic supplier (or lumber yard ) and then there will be no issues in the kiln Link to comment Share on other sites More sharing options...
Callie Beller Diesel Posted April 17, 2022 Report Share Posted April 17, 2022 The trapped air thing works. It’s pretty cool! Link to comment Share on other sites More sharing options...
