Will PVC piping bend under a wire tension?
I'm looking to make a hot wire foam cutter, and have most of the setup all outlined. However, the 'bow' still need to be made, and I plan to use PVC. Reason being is I would like to be able to stick some four/three way bends on one ended as to allow me to stick the bow on a stand of sorts to make a band-saw style hot wire.
But, question at hand: if I were to make a frame out of PCB piping for a hotwire, would the tension of the hotwire cause the frame to warp? And if so, what would be an equally cheap option for the frame?
