Stripped nipple in new wheel build
As I was truing a newly built wheel I stripped a nipple and can’t back it out (the spoke end prevents putting a screwdriver to it). The spokes are all pretty damn tight at this point. Is it time to grab the wire cutters and sacrifice the stainless steel spoke? FYI: I built the wheel with used spokes, anyway.

Steel is real
no
once i stripped a nipple, but i needed to tighten it one more small turn.. so i grabbed a pair of small lock jaw clamp pliers
you could use such a tool to unscrew & remove the nipple

The threads are stripped? Or you rounded off the external wrench flats?

You can put a notch in the center of a screwdriver blade. I've done this when I had to remove a rounded off nipple.

Remove the tire and rim strip, then remove the nipple from the rim hole and replace it, assuming the spoke isn't protruding through the slot of the nipple.

Are they aluminum nipples or brass? If the latter, perhaps the universe is trying to tell you that the spokes are too tight already.

And you might also want to verify that you are using the correct size spoke wrench - it is easy to round off a nipple when it is really tight and your wrench is too large.

Ditto on the vice grips.
Then use splined spokes...solves the rounding off problem. They come in a bunch of nifty colors as well for when you have a color scheme goin'

I also agree w/ the suggestions of using vice-grips and checking to make sure that you've got the right size spoke wrench for the nipples you're using. Good luck and let us know what method worked for future reference!

I strongly recommend the Cyclus type spoke wrench which grabs 4 sides of the nipple over the slotted Park style wrench. A great $6 investment.

"4 sided" spoke wrench, lubricate rim holes and spoke threads before building (tightening) and use brass nipples, not aluminium ones.

I agree that 4 sided spoke wrenches are better than the slotted wrench. However, Park also makes a 4 sided wreck in two sizes, the SW-40 and SW-42.

One other thing to consider once you get this nipple off is, are the spokes so long that the nipple is trying to thread up beyond the top of the spoke's threads? If this happens, it becomes really hard to turn the nipple and might be a reason that the spoke wrench flats got rounded in the first place.

No, if the spoke is protruding beyond the end of the nipple, it means the spoke is too long. Changing the nipple length will not fix this.

The spoke is not protruding, just coming close to. The spoke calc suggested 298.2mm; I grabbed 298s. I suppose 296s would have done as well.

Should have used double square or squorx nipples. Tension from the top. And lube your threads. The slotted head nipples are 1800s technology.
