Combining two tent poles with a USGI poncho to make a shelter.
Specs of the USGI poncho: 96x66 inches. ORC Industries states they are the sole source provider for Wet Weather Ponchos to US Armed Forces "since 1982".

I bought the 11'3" pair of these poles:

I modified each pole to be ~126" overall and added winged wire nuts (in this video) to stop the ends from sliding through the grommets.

I've since changed this to a stopper I designed in FreeCad and had 3D printed. Further details in the Alpha Tent video where I use the USMC Field Tarp, another ORC Industries product.

There was some seepage, at the tabs for the waist cord. I rubbed Seam Grip into and around the stitching and that sealed it up.

This seems to be the original, though he didn’t calculate the 8% length determinant to make it suitable for other sizes: (and I didn’t drill the wing nuts lol)
