Replacing the grindstone

[grymoire]

I have a 8000 grit replacement grindstone (from Woodcraft).
How do I remove the grindstone from the arbor so I can replace it?

When I try to loosen the nut, the entire arbor turns. If I hold onto the honing wheel, the honing wheel comes loose.


I removed the entire assembly, and I wasn't sure how to proceed. I can put a Vice Grip on the arbor and clamp really tightly, and try to loosen the nut, but I am concerned that I will chew up the smooth arbor.


I tried WD-40 on the nut to help, but it didn't.

Any suggestions?

Sorry for the delay in replying.  I'm kind of computer illiterate, and got locked out of my own house!  

The best method to loosen the nut is shock, rather than smooth application of pressure.  In other words, get a bigger hammer.  Put a wrench on the nut and smack the other end of the wrench with a hammer a few times.  The nut should come loose.
