Nice work.

How do you do the tinning of the copper surface?

Boiling in water with citric acid and Rose's metal :sorcerer:

is the video showing the process (unfortunately in russian, but it`s quite descriptive) All you need is citric acid (works with acetic too), Rose`s metal and cotton swab or wiping blade for cleaning redundant tin from plate.

And

video showing the cleaning process.

It is very descriptive.

Dont know where I can find Rose metal :sad:

I have to search

Thanks

You can use Wood's metal (50% bismuth, 25–28% lead and 22–25% tin) instead. Its melting point is lower than Rose`s

I`ve bought it at local radio store.
