Gold Plated Spinning Top
« on: August 10, 2018, 09:14:20 AM »

Hi!

I make brass flywheels for my spinning tops. I use sandpaper and diamond lapping pastes (up to 0.1 micron) to achieve an excellent mirror finish. The issue, however, is that after a few weeks, especially if I handle the flywheels with my fingers, an ugly clouded patina forms. This is not too difficult to remove but is a little irritating.

This problem is what gave me the idea to gold plate the flywheels. Gold is very unreactive and does not form a patina over time. This makes it ideal for jewellery. So, I did some research and found someone willing to gold plate 2 of my brass flywheels in 18 k gold. After about a week, they were returned.




This is before plating




Fly wheel 1 after plating

I understand gold is soft and may rub off is mistreated. I will take care of the tops dearly and even if the gold rubs off, it would not be too much of a disaster. The brass underneath is also nice and the gold plating was quite cheap. Please, feel free to tell me what you think!

Gold plated?  Wow, that seems pretty hard core!!!

But, it does sound pretty.

I found out the other day that Techmetals company is 15 min from Miamisburg.  I will tour their facility.  They do a wide variety of hard surface long wearing exotic PVD coatings.

Hi, James.

I had one month holidays in Finland, no computer, no TV, I was totally disconnected from the rest of the world.
Yesterday I have come back to Italy.  I see now this post.

Thank you very much! I am now trying to use this ring on my next top, Nr. 11. It will be aluminium - brass. I will make a video eventually.
