I thought this was super cool! Check out the before and after pic:
Details on how it was done:
Sure thing! I used Whink Rust/Stain Remover to remove the anodization on each half with the pads/bearing/axle removed by submerging each side in it in a glass jar for about 15 seconds.
The stonewash was pretty easy. I put in some cheap pads and a bad bearing to protect the important parts, and assembled the yoyo. Then I took a plastic jar with screw on lid, enough small aquarium stones (washed to remove dirt) and added them while damp to fill the jar about half way, tossed in the yoyo, and closed the container. I wrapped the container in a couple of towels, taped it up, and tossed it in the dryer on the no heat setting with some loose towels for about 2 hours. Washed off all the debris, replaced the pads and bearing, and it’s good to go.
You have to be careful to not stonewash for too long, or you can end up with a more shiny appearance, kind of defeating the purpose of the treatment.
I wouldn’t do this with an aluminum yoyo b/c the softer metal will likely get some serious dings/dents from the rocks. Titanium works really well to keep it to only small surface scratches that look great in the end.
I actually think this would work fine with an aluminum yo-yo, if you stick to smaller, less dense “rocks”. Maybe even sand?
I’m really intrigued by the idea of putting your aluminum yo-yo in a plastic container, partially filled with sand-ish stuff, wrapping it in a towel or two, then letting the dryer run on “no heat” mode for a few hours.
You just created your own blast finish!
