Galvanised disks

I have just received a batch of galvanized disks for making magnet rotors.
Some ten 300 mm diameters and a pair of 660 mm for my big windmill.
No more rusty magnet rotors!
It cost me 64 pence per kg, which comes to about £3 per small disk (about $5).
Transport was a bit more expensive going via the galvanizers,
but I think it will be worth it.

Cost per disk:
cutting £10
galvanizing £3
transport (in total) £7
Total was £20 per galvanized disk delivered to me in a batch.
