So this is what I'm faced with:
A Guy wire is out of the question, the poles are right on the corner.
Swapping out the poles is no easy matter. The wires would have to be cut, the poles removed, beefier poles constructed, the holes enlarged to accept the larger poles, new wires spliced in to replace the cut wires, and then all tied together.
There is no easy way of doing this. So I just jumped right in and fabricated new, beefier poles from solid, hard 5/32" brass rod, painted to look like wood.
The eye bolt was carefully removed from the old pole with the backbone and pulloff wires still attached. The old 1/8"diameter pole was removed and the new one installed. A new wire was wrapped around the new pole and attached to the old eye-bolt, maintaining the original tension. And were back in business. Yes sir! We're back in business!
