How to remove seized waterstone on T8.
I bought a Japanese water stone for my 2 year old T8 tormek. When trying to change take the original stone off it won’t come off. I have taken the nut off but the stone won’t budge. I have tried pull the wheel will tapping the shaft with a aluminium block, but it won’t budge. How do I get it off?

This is strange. This can happen on the older non‑stainless steel shafts, but not on a T‑8. When you loosen the stone, you rotate it clockwise, this action prevents the stone from getting stuck. However, if the stone has been sitting on the machine for years, it can be a little difficult to remove. But once the EzyLock is off, it normally should not be a problem.
For the EzyLock to work properly, it is important that the inside washer is able to rotate against the shaft. Some penetrating oil can help loosen the washer. But in your case, it seems like the shaft itself has bonded to the center bushing in the stone.
Do you have access to a vise?
If so, you can remove the honing wheel and the drive wheel and pull out the main shaft with the stone attached.
I would suggest using a vise and opening the jaws so they support the inside washer without clamping the shaft itself.
It is very important that the jaws rest on the inside washer; otherwise, you risk cracking the stone.
Hit the shaft with a metal hammer to break the bond. You do not need to hit it very hard, just enough to free it. Be careful not to damage the threads.
Once the shaft has loosened, you can apply penetrating oil to ease the wear in the center bushing as you tap out the rest of the main shaft with a plastic hammer.
Clean and grease the shaft (the section that goes inside the stone) before mounting the stone or diamond wheel on it again. Do not forget to apply grease on the inside washer where it contacts against the main shaft.
