The bike: Awesome, always great to hear that repairs are victorious over buying new.

Wow, I didn't know the spoke thread rollers were THAT expensive. A former employer did thread rolling on a different part, I never saw the machine internals. I can think of several ways of implementing one, but I have no access to a machine shop, and the local bike shop has a roller. I think I'll go there soon and buy at least 3 each of the lengths I need, so after a breakage I am not counting on them still being open. This is the kind of thing you want local, rather than paying shipping for 9 spokes. Good to know that Park Tool still makes one and parts... or do they?! I see none on their website after search, I'm gonna look at the comments above more carefully... OH, not Park, but Phil (Wood); Yep, there it is, and for what I see, as a former machinist and engineer, that price must be based on every part prototype machined. One would think that based on economies of scale, they would do a short production run of the things. Premium pricing. Somebody will make the same and undercut them by a LOT.

There's one on Amazon for $90 for 14g, Cyclo (I have one of their chain tools, not fancy but 36 years and still going), either spoke is clamped and wrench on the tool, or secure the tool and power the thread by grabbing in a drill motor, if the curved head will fit behind the chuck jaws, probably. Cutting the spoke to length first can be done half a dozen ways, I would use hand cutters like a bolt cutter, then dress the end flat and to length on a grinder or sander.
