First thought that comes to mind is - why not make a new nut?  Isn't that why most of us are here?

O if it was that simple don't have the right gears to set the lathe up to cut the thread needed

[sparky961]

Not sure what threads you're looking at, but is there a nut or something else with the same threads that could be modified or repurposed?  Maybe have someone else do just the threads and you finish the rest?  Just trying to think outside the box a bit here...

I had some INT30 collet chucks with mill when i got it (changed all to R8). The nut was not anything special, i would try and get a normal nut and weld a plate over the end, there was a small radius in the bottom of the nut if i remember right? but you could turn the front of the nut out and turn a plate with the radius so it drops in?

Just an idea

Hi Bob,

No dilemma, sell it and buy something else

It appears that the nuts are available at least on this side of the pond. Not sure this is the correct size but if this size is available other sizes should be also. They don't want an arm and leg for them either.
