I have a couple of silver plated brass goblets that need re-plating. We
don't really want them - do any people replate such items for their own
pleasure - or to sell?

Bin or Ebay?

Those kits look terribly expensive.

I remember my Dad, who retired into being a chemistry teacher, doing
nickel and silver plating in the garden shed. I suppose I should have
taken more interest.

All I remember were small electric motors with glass rods as the
stirrers, tanks of chemicals and power supplies. I think the psu's might
have been old battery chargers. It all looked Heath Robinson and cheap.

I seem to remember him replating several door knobs, but that was
probably just nickel plating.

Youtube shows how to do most things.

Silver plate generally has low saleability/value these days.

Give them to a charity shop.

Unless they have a market value of more than a couple of quid they will
not be resaleable and the charity shop would rather not have them !
Freegle them or recycle.

IIRC silver plating is fairly easy, nickel plating significantly more
difficult.

One of the issues with silver plate is that it tarnishes fairly quickly
in air, hence the need for regular polishing (and why you find it worn
off old items). I imagine you could use the same lacquer that is used to
protect solid brass items.

You have it back to front. Nickel plating was relatively easy to do.
Precious metals commercially are done from a cyanide bath although other
less toxic complexes are available these days for hobbyists.

If you try to plate from a simple silver nitrate bath you get black
amorphous silver powder deposited as the base metal surface dissolves.

To get a good bright silver finish it is probably better to take them to
a specialist electroplater. Half the battle is getting the job
absolutely grease free before starting and using the right current density.

One of the issues with silver plate is that it tarnishes fairly quickly
in air, hence the need for regular polishing (and why you find it worn
off old items). I imagine you could use the same lacquer that is used to
protect solid brass items.

There are some sophisticated surface chemistry modifiers available that
put a very thin protective layer on silver which delays tarnishing. Also
today there is a lot less sulphur in the air than in the old days of
coal fires in most homes using sulphurous coal and winters smogs.

Bit of thread drift here. The old Rover has lots of switches all of the
same make and basic design. Those that handle a reasonable current are
pretty reliable. But some only control relays, so a tiny current, and need
cleaning regularly. Contacts on all are plain copper, with no wiping
action, and they corrode. Wondered if silver plating the contacts would
help? Or any other DIY plating?

Silver is the better conductor but gold is better for resisting
corrosion.
