Maybe someone can tell me where to find the coarse thread parts though so I may yet get some use out of this one.
Pinch flats happen. It's frustrating, but it happens sometimes.
As for the coarse threads. Check Golem Gear.
Their wing are similar to a European wing brand call Absolute Tech Systems (ATS).
I owned one, and needed a replacement for the OPV; Golem gear wings looked the same as my ATS wing. As it turned out, they were the same wing.
The Golem gear OPV was a perfect fit.
Perhaps contacting HOG/Edge might get a new OPV with the coarse threads.
