seized spoke nipple

i have a wheel that has been through a lot of abuse, winter grime, etc. one of the spoke nipples snapped and i need to replace it, but the nipple (the threaded part anyway) is seized onto the spoke. i've tried dropping triflow on either side but still can't seem to get it loose... i'm putting a lot of torque on the spoke and i'd really prefer not to damage it if i don't have to.

any suggestions?

This is the easiest,and for all practical purposes the only, solution, except that you'll also need a new spoke. Doh!

Have you tried using the slot on the back of the nipple to turn it? If the spoke head is poking into the slot, you may need to notch a flat head screw driver to turn it. Alternatively, you could loosen several spokes on the opposite side of the rim until the problem spoke has very little tension. That may help you turn it easier.

the nipple has broken where it "mushrooms" into the rim, so the spoke has no tension on it, but the end that accepts a flathead or nipple driver is broken off.

So you just have a chunk of the nipple left on the spoke? I would try making a very slow cut into the nipple until it broke through to the threaded portion. At that point, the piece should come right off. A Dremel with a cutoff wheel would do the trick.

I would use some Liquid Wrench on the threads, let it soak in, hold the spoke with pliers and turn the nipple off with a good spoke wrench that holds all 4 corners or, if necessary, another set of pliers.

I'd apply some heat to it and then turn it. It has worked many times for me on other people's wheels. If this doesn't work, put a vise grip on it and turn it, if the spoke snaps, doesn't matter, your replacing it. Using a dremel your most likely going to cut into the threads or the spoke.

Life sucks sometimes... Really if you can't make it come loose easily enough with any of the methods then you're likely not going to want to use the same spoke anyway after being through enough abuse to make the nipple let go of the threads.

Far too likely to damage the spoke. If it comes down to that then just cut the darn thing and get a new one. You're obsessing over a 40 cent part.
