---and you really do want to spend some time and find a good shop. Maybe one of the vintage boat restorers would have a shop. It takes a lot of experience with old non-ferrous castings to be able to extract all the salts and oxidation/corrosion out, before replating. Many bike shops plate aluminum alloy based parts. My guy tells me this is a whole different ball game from brass,bronze work.
so many projects--so little time !!
