elight,
Congrats on the EarthTainer build!!
Were there any part of the instruction that were confusing or unclear? I always want to improve the clarity of the Guide.
Regarding the bending tube, neither Lowes nor Home Depot carry this tube. You have to go to a full service Hardware store or Welding Supply store. I found it more convenient to order it on Ebay at the link I have in the Guide if you don't have a full service Hardware store locally.
