I don't know if this is that new or not, but I haven't seen my design before.
I wanted to add leaping light arches to my display this year. After looking at designs on this forum I was not sure it they would hold up in my area. My thought was, plastic, in possible sub-zero temps, under pressure; and accident waiting to happen. I also wanted to line my walkway with them, no room for guide wires. What else could I use?
My design uses 1" conduit and 3/4" black pipe. I purchased 10' lengths of 1" conduit. Took it to my local awning maker and had them roll it into arches for me. I came back with an arch that was approximately 8' wide and 3 1/2' tall. Following standard light wrapping, I was able to put seven segments of 100 lights on each arch.
Placing them in the ground was another design. I found that 3/4" black pipe fits almost exactly inside 1" conduit. So, going to the local Home Depot, I purchased 4' sections of pipe. Took them home and cut them in half on a sharp bias to create ends with a point. Unfortunately I found at final assembly that when you roll pipe it shrink slightly. This was fixed by a friend and a metal lath and milling a little off each end.
The spikes are driven in the ground approximately 18" leaving 6" above ground for the arches to sit on. They are rock solid, do not move, need no guide wires, and are very weather friendly.
Hope this design helps.
