That's genius! It seems that the small cord pulling in on one small portion of the I.D. is the key. The rest of the tube just follows along, nice and smooth. Excellent! Thank You! 👍❤
wonderful idea very much like steam bending wood If your line starts deforming the inner wall of the tube try lubricating the the line with paraffin. If you need to weld the tube be sure to clean them very well with alcohol or acetone.
That is awesome! I have garden foil tent, however original tubes for its structure ware destroyed by wind and rain. I was planning for some time to buy beefier tubes and replace damaged ones, but wondered how to bend them nicely.. And that will work - THANK YOU!!
Very good idea, seems to work nicely. As others have mentioned, a standard way is to fill it with sand. One alternative to sand is salt, which has the advantage that if the filling is difficult to get out, then salt can be dissolved and totally rinsed out with water. But your idea seems better for simple convex shapes, like circles.
This is awesome. You could get some flexible gardening or flowerbed edging to put on the outside of the wooden blocks to prevent the small indentations you spoke of. Or use stacked plywood.
Nice. I suggest you don't pull the tubing from the center. Use some pulleys that can pull at the 90 degree position at the near radius. Install guides to separate the two tubes as they approach each other. They will cross the midway under tension but can be easily aligned into a circular shape as they are released from tension.
@@benjamindover7050 yep, water works for smaller tubes, but the majority of YT videos suggest sand. Considering that he's pulling a rope through the pipe, sand sounds like a better approach since water would more easily spill out and also requires sealed ends (or has to be frozen) in order to work. ps. Most of my work has been with PVC for which hot sand is awesome as it bends the PVC easily, holds heat better and the PVC pipe keeps it's shape once cooled (but I will have to try Hot water some time as it sure is easier to get hot and to get it into the pipe)
It looks a little bit terrifying, at least in a video. Not sure what is the tension there, but I would maybe add a little bit of support to prevent tube from popping out.
