Being a cheapskate I made mine using 4 foot Fiberglass hollow garden stakes and 4 foot Aluminum solid rods cut the top off each to the length I wanted mine, to also use as walking sticks, slid the aluminum rods in the garden stakes and sprayed in some expanding foam to prevent anything from being loose. Spray painted them and capped them off with a foot of black rubber hose on each of the garden stakes super glued in place and hold every thing together with a rolled up section of bicycle inner tube at the bottom of the rubber hose.
