To re-install the stator involves threading the right leads through the correct holes. I found this difficult.

The way that I did this was by tying pieces of thin string to the leads, and threading those first. But it was then difficult to manipulate the crimp connectors through because the strings had to be tied above them. It took some patience with a variety of probes to achieve this. Perhaps you can find a better way?

Thr grinder is nominally 750 W, but the UK mains plug had a 13A fuse. I suggest instead a 5A or even 3A fuse.

The body of the grinder is plastic: I am not sure how durable that is. At least one screw thread was somewhat damaged. Almost all of the screws are self tapping: it might be possible to insert small strands of thermal plastic to restore grip.
