Hi all,

I recently upgraded my Harion Skerton Hand Grinder with this stabilizing washer, and I have noticed a mark on the Burr Shaft after a few weeks of use. It appears that the shaft is being worn out at the spot where the upgrade washer sits, and I am worried that it might lead to metal particles in my coffee.

Picture below, any suggestion on how to fix this?
