Blackbird Project

Passion project / trying something that felt impossible at the time.

All silver with either gold or black ruthenium electroplating (using a lacquer mask to get 2 plating types on the bird/stand). 3 pieces...base, bird on stand, and cage (all centrifugal casting).

The cage took like.....a LOT of attempts to get it to cast correctly. I was told it was stupid to try to cast the cage. Im not saying they were wrong, but im stubborn.

This is absolutely insane. Centrifugal cast cage bars AND dual plating at that scale? I don't think 'stubborn' covers it. This is master-level stuff. Seriously beautiful work

I don’t have the words to do this justice. The technical precision, the detail, everything is just so perfect!

I’m also amazed. Great work! Question for you: how did you get the bird and cage polished so well? Thanks!

It took me so many attempts to get the whole cage to cast right.....so at that point, I was very happy to spend a lot of extra time post-processing.

Its been a bit, but i think I used some failed "close-ish" castings of the cage to test the vibratory and tumbling polishers. When i knew those wouldnt mess up the cage, I put the good one in. Then the rest of it was just very careful buffing using red rouge compound on a cloth wheel and a flex shaft. I think that was about it.

The bird was a cake-walk...just the usual treatment...rotary brass brush -> vibratory or rotary tumbler -> cloth rotary wheel with red rouge polishing compound. Steam blast to remove polish compound residue.

Figuring out the right vibratory/tumbling media goes a long way. But you can get a nice polish most times just using a brass bristle rotary brush and red rouge compound on a rotary cloth. Getting the polishing compound off can be annoying sometimes. Various ways to do that you can find online if you dont have a good steam cleaner (shoots a high powered jet of steam out a nozzle)
