Anyone in Sydney have a lathe (or a mini lathe) that I could play with?

In short I want to sand/mill down a set of hub rings by 0.6mm or so to get them to fit the wheels I have (I have 64mm rings and need 63.4). They are ABS plastic so should sand down pretty easy...

Plan B is to order another set from the UK in the right size (or see if I can actually find anyone who has them locally).

Anyone help with either of those two options?
