What to do with old bicycle rims?

OK, here they canibalize bicycles. Usually all that they throw out are old frames and rims. So your mission, chould you decide to accept it is to find something more interesting to do with a discarded bike rim than making a crab net out of it. (ps. spokes and freewheels are included with most rims)

I'd say, Bicycle trailer.

That is a good good idea too. I have seen some great plans and instructibles for trailers. I think I will build a few of them next spring. I think I might build a couple of pull carts for the dumpster divers that don't have bikes too. I see a few of them with those shopping carts and the wheels are too small. They really have to struggle to move them.

hit it with a mallet and smith a sword?

"Hit it with a mallet and smith a sword?" Hmm, maybe? Most of the rims I fond lately are aluminium alloy and might be better for melting and casting than forging. It is not a bad idea though. I have got a lot of old rims around here. Maybe some of them could become swords. But only play acting swords because I don't like making serious weapons anymore.

you could make a toroid winder
I have piqued my curiosity, how do you wind a toroid with a bike rim ?
yo9u cut the rim at one point so that it can bend slightly. Slip a toroid in so that when the bike rim is closed, it can spin inside the toroid. hold the toroid via a chuck like structure (3 wheels that can be rotated by a geared down motor, thus turnning the toroid). The bike rim is turned by 3 motors holding it in place around the rim that rotate it (so eccentially you have a ring that can be rotated without having a central axis). You run the bike rim's motors in reverse, winding a lot of magnet wire into the rim. When there's enough you tape down the other end of the wire to the toroid. With some fancy low friction release system (I know how it works, but to complicated to explain here) when you run the bike rim motors forward the wire started getting wrapped around the toroid while the toroid's motors are spinning, thus winding the wire evenly around. That was a mouthful of words.
So, in this scenario, the rim has no spokes in it, right ? Somehow I am at a loss to picture this.....you wouldn't happen to have a picture would you ? :-)
right, no spokes, here's a youtube video of a real toroid winder so that you can see where I think a bike spoke might work:

That is truly an ingenious device and I never knew such a thing existed before. Thanks for the idea. It is a bit too ambitious for me to attempt(and I don't wind toroid coils), but it is an interesting idea anyhow. Very good!
Ok that is what I thought you meant, but I wasn't absolutely sure, thanks. Yes, it might be possible to use the bicycle rim for this, if it is sturdy enough (too thin and it might wobble).

Check out my bike wheel/crutches stool project on this site. http://www.instructables.com/id/Stool-made-from-bike-parts-and-crutches/ Check these two links also.

I salvage some rims from our landfill. I bring bolt cutters and snip through the spokes and recycle the rim if it is aluminum. (Someone comes through once a year or so and buys all the scrap metal for recycling so the spokes and hub that are left behind still get recycled. I just get maybe 50 cents for the effort.

That is a great looking stool.
zieak scafool5 years ago
The one I made? Thank you!
scafool (author)  zieak5 years ago
I was just wondering about if you save the spokes too. I think they are stainless steel and worth more than regular steel as scrap, about 75 cents a pound I think.
zieak scafool5 years ago
The place i have sold to doesn't buy stainless so i leave them behind. But i'm sure the barge that comes through and buys all the metal likes that they get plenty of stainless mixed with the steel.

Make a superdupermultiphasic polystringic one of these.
scafool (author)  caitlinsdad5 years ago
If I clamp the freewheel (cogs) to a support with bolts it could be human powered. (right?) (That is kind of cool, nice) Now about "superdupermultipolyphasic..."
I guess you could put a bicycle up on an exercise stand and run a belt from the rear wheel to your first rim. I look forward to your public art work installation where everyone jumps on the bike and swat at the moving loops of string and watch the psychodelic reflections off the multiple spinning wheels. Good luck.
scafool (author)  caitlinsdad5 years ago
LOL, but now you have me thinking about something wind powered, maybe in Saskatchewan
Giant burning man scarecrow with spinning reflectors to look like it is on fire in the sunset. Cool!
Oh, and this.

that is a winner

A few ideas from this link, it's in french but the pictures are self-explanatory:

I like the racks for firewood! Thanks

Use the wheel to make a game of chance spinner. Put a little tab dealie on the wheel, mount it on a board with numbers around the rim. What number it lands on corresponds to the number on prizes. Kids will line up all day long for rocks at .25 per spin.

Wheels are great for oversized "gyroscopes" (gyroscopic stability is was keeps the bike up in the first place, so if the rims are big, like 27 inch or so, they are super good at this).
