Hi all,
My cheapie air 1/2" rattle generally removes the centre nut no problem, but not with this full crank that had been semi exposed to the weather for years on end.
I grabbed my emergency electric impact gun that I keep in the boot of my car that runs off the ciggie lighter socket. This one doesn't have the usual series of quick hits per second, instead it operates with a series of heavy bangs once per second. Sounds odd ,but it gradually succeeded in moving the nut after a few seconds of persistence on and off. It was satisfying to see the red oxide dust emanating from the stud with each bang of the gun.
