Never tried doing it myself , but if you ask the plating firm if you can wire up all the parts yourself so they just hang all the parts of the racks it makes it so much quicker . A standard restore takes about 10 m of cooper coated wire to get all the parts Zinc plated . I obtain for the wire from them and spend two hours fitting every nut , bolt , shaft , bracket etc ( even spokes and nipples ) to the wire in 1 meter lengths.Then give it back to them , get it back in 2 days still attached to the wire . All for 60 bucks . I'm in Perth , so cant comment on other states . The wiring up takes the time , hanging on the racks takes minutes .
