For plating you need a bath with a solution of nickelchlorate, nickelsulfate and boric acid. I purchased a readymixed pack of salts.
I used an adapter for the current of 3volts.
On the positive (anode) I put a nickel gauze On the negative the workpiece (kathode).
Now the nickel ions travel thru the solution from positve to negative and deposit on the workpiece.
Its important that the piece is scratchfree, polished and clean. With a current of 3volts it takes about 4 hours to get a nice plating.
Don''t try to speed up the proces by using a higher current un less you want to plate larger pieces. The result will be less shiny and there is a risk of uneven layers.
On youtube there are some vids on home platig.
Beware to wear gloves and a mask working with the salts they are toxic and avoid to contact your skin with the solution.
When the plating is done rinse thoroughly with hot water otherwise your work can turn green.

I hope this is a clear explanation?
BTW my apologies for posting some pics twice in my previous post.
