…to donate or sell for cheap?
These are Skyway Tuff rims, and I got a request to do a piece using something like this as the background. But they’re really expensive new, even used. This particular pair is black with gold flanges, which would be my preference (or just black), but any color is fine.
This is a weird idea, but…as I drive around town I see those yards full of bikes and bike parts, maybe stop and inquire if you can look for old bike parts for a sculpture. Maybe you will find what you’re looking for or know where to look in the future for bike parts. Just an idea. Maybe they need a part welded in exchange for parts, I love to barter when I can.
I haven’t seen any in yards while driving around. I check every garage/yard sale I see, and on FB marketplace, eBay, etc. but no luck so far.
That is to say, I don’t really see them for under $100.
Oh! They’re known as mag wheels, because they’re made of magnesium alloy. Which means I probably shouldn’t actually weld on them.
You can apparently do it with TIG, but I’m new to TIG welding and don’t really want to mess with something that catches fire extremely easily. But I can weld something and attach it to the rim without welding onto the rim itself.
I did find a pair on FB Marketplace for $50, which is a lot less than I’ve been seeing.
They look like this. I like the star shape. Still vacillating on whether to buy them.
If they do catch on fire never put water on it as it will explode, just take it outside and throw dirt or sand on it. Dont waste a fire extinguisher because it most likely wont work either.
Yeah, I found this while looking for more info:
In the event of a magnesium fire, it can only be put out by starving it of oxygen or using a Class D fire extinguisher that is recommended by the U.S. Department of Labor Occupational Safety and Health Administration (OSHA).
Not sure I even want to risk that. 
Even worse is if magnesium metal and iron oxide are combined. Starving of oxygen won’t happen until all the iron oxide is consumed and burning is hot enough to burn into concrete and to liquify sand.
(Search thermite for more information, but searching may get one onto a watchlist).
