I made my own without a welder. Upon finishing these I found added material that may have been as good but lighter and cheaper.
Home Depot - 1/2" galvanized threaded pipe.
1 - 5' section
2 - 2' pieces
1 - T fitting
1- 2' piece of 1/4" rebar
Thread T-Fitting to end of the 5' section and put each 2' piece on either side (looks like a T). Its not real heavy and can be broken down easily. I cover with a Tyvek paint suit from HomeDepot or Lowe's.
Drive rebar into the ground for a support stake.
Total cost $22.
I did see the plumbing section has 1/2 " copper tubing/fittings that may work well and be light but would be suseptible to denting.
Hope this helps.
