When I saw this I wondered if this is proof that when workers were removing outdated lines that they did actually throw them thar old insulators down the posthole? I guess that over time some of these insulators sprouted and grew into, ahem, a hemingtree.
I made this tree from sixty, four pin tramp brackets. It holds 200 insulators. Although it took many hours to figure out the best design it takes a minimum of welding to create the frame, which can be disassembled for transport. The brackets bolt together and this allows some degree of flexibility in their position.
