Assembles and dissembles in seconds, by hand.
CPVC (compact PVC) tubes, 7 x 17" long
T coupler x 1
Straight coupler x 3
Tool: any PVC tube cutter, small saw or big scissor. Borrow from neighbor or ask for tube to be cut in store. It only takes a few seconds to cut.
Cut tube into 17" sections.
Print your signs on letter papers 8.5" x 11".
Use transparent tape to hold 4 or 6 papers together to form a 17" x 22" panel, or use 6 papers to form a 17" x 33" panel. Tape the panel to a 17" tube at each end. Reinforce attachment using strong transparent packing tape.
Repeat for panel 2.
Test assemble and dissemble. The couplers can easily be hand tightened, but will not fall apart under strong winds.
Fold or scroll paper panel for easy carrying. Alternatively, the big panels can be used to hang or stick something else on site.
Make the vertical handle tall, just under eye level or face level from ground. It can stand on it's own so it's easy to hold while you are standing up. You can hold it while sitting down too. You can also easily tie it to some other poles.
Research from else where says every 1 inch of character height is good for 25 feet of viewing distance. So a 4 inch high character is good for 100 ft, suitable for drivers passing through. The distance is based on Helvetica font, black on white, all cap letters.
