Hub snapped off in freewheel

Ebay lot. How would you get this out?



Seller doesn't know:

Now for the bad news. In the second picture you will see the butt-end of an American Classic freewheel hub which broke off during a ride, after I had attempted to remove the freewheel
Someone paid a lot for this so I am guessing they know how to get it out.

I don't have a clue. Lot of money just to get the cogs.

Send it to cudak888! He loves challenges like this. My guess; dissolve it with the appropriate chemical.

You might be able to take a 6" piece of 1/2" all-thread, put two jam nuts on one end, feed it through the hole in the hub from the left side (in side, frame side), thread a couple of nuts on the free end of all-thread, and use the nuts to clamp down on what's left of the hub. Clamp all-thread in bench vise and use a freewheel tool to remove freewheel.

Alternatively, drill and tap a series of hole in what is left of the hub, screw it to a plate or bar, put plate in bench vise, use freewheel tool to remove freewheel.

If neither technique works, go get a beer, sit down and stare at freewheel until you think of something else. Beer fixes almost anything.

Sodium hydroxide (NaOH; aka "oven cleaner") will dissolve aluminum.

There's a tool called a "screw extractor" that's a tapered shaft with a barber pole of splines up it. You jam it inside, twist to engage the splines deeper and deeper, until the friction of the exterior threading loses to the friction of the tapered splines biting into the inside diameter of the thing being removed. This presumes right hand thread, I think, so should be OK for a freewheel. And I think that they come large enough.

Take your choice: $15 to $60 at Sears for sets.

What's the name of that stuff that is used to remove stuck stems from headtubes? Or some other high-penetration oil. Soak it for a day in that. Find something metal about the same size that will fit through the freewheel. And beat it with a 2-pound rubber-mallet. Or is it actually engaging the threads of the freewheel??

Bizarre!
