Hario Canister Mill Inconsistency

I recently copped the Hario Canister Coffee Mill.

It's a pretty little thing and I'm fairly happy with it, but like the Hario Skerton, the burr wobbles heaps at coarser settings, resulting in a ridiculously inconsistent grind size. At the moment, I have resorted to wrapping some washi tape around the burr shaft which has helped just a tad.

I'm aware that the Skerton has mods but I haven't found any for the Canister, any suggestions?
Or if you also own a Hario Canister Mill, I would love to have a chat :D
