Electroplating questions

[BaldricParticipant @baldric]

I am considering copper electroplating a cast brass chimney cap, looking at the ENV aero engine (part 5) in Model engineer 2018, 2nd March, I can get an idea of what I need to do to get a reasonable thickness.

I will need to solder the cap on to the chimney, so the question comes as it if the platting will stand up to soldering or if I need to solder the chimney first and accept that parts of the chimney will get plated or that I will need to mask them off in some way?

The other options I can think of are to spin a cap, never done that before, or I could have a go at electro-forming the whole cap on some of former, as I have the cast cap already, I was thing on using that, just I don’t like the colour.

Thanks in advance.

If you spin a two piece one its quite simple especially in copper as when freshly annealed its as soft as butter.

The cost of setting up for plating Etc Why not machine from solid or form a ring and then machine the profile. If all you want is the colour dunk the VERY clean brass casting in copper sulphate to coat it – it will soon be sooty ! Noel.
