Step 2: Making a Frame to Hold the Pipes
I think you could probably builds the frame out of wood or other material. I decided to build this with L shape steel rod.
Cut the rods to length to make a rectangle. on the shorter side , I made some notch with a hole saw, so the pipe will fit in. Weld the rectangle together. If you don't have a welder, or access to one. You could also drill and bolt the part together. I used some rubber to isolate the steel frame from the coper to prevent metal reactions.
