Do you know anyone with a bench grinder and polishing disc, that you could borrow? It would speed things up a lot.
And you are probably aware, that the shine will lessen over time as the raw aluminium oxidises
I do have one, but it's a jewellers one originally which I've butchered to enable access with larger (bike) parts, but it's a small spindle, I don't know if I can fit an adapter on it to fit bigger wheels. And the wheel I have doesn't fit too well on it so it's a bit of a struggle sometimes.
Thanks, although in detail still a lot of work to do... Definitely waiting the end of the heatwave to carry on!
