How can I build a simple,rugged crusher that will crush a high volume of aluminum cans? Answered

I can weld steel. Prefer components that are used and commonly available. Should be as light and small as possible.

Pneumatic PVC Can Crusher

I have put together a very well documented guide, to build your own pneumatic PVC can crusher. This can crusher is constructed from easy to find parts at any local hardware store. For more information, and a video of it in action check out my website. Let me know what you think, Thanks http://cancrusherguide.webs.com/

Does anyone have a plan for a motor driven aluminum can crusher that can crush multiple cans at once?

My family collects a large amount of aluminum pop cans each year and takes them in for scrap every few months. The problem is that it takes so long to crush them all by foot. I've done some looking and have seen can crushers (mostly mechanical) that crush one at a time, but I'm looking for something with a electric motor and some sort of small hopper where I could dump cans in to be crushed and dropped into a bucket. Any ideas? Thanks!

Can Hardwood Shred ABS?

I am thinking of making a prototype plastic crusher/shredder out of a hardwood instead of steel. Do you think that a hardwood would be able to grind a plastic such as abs into small pellets? If so what kind of wood would be best? What if I made a plywood out of hardwood to strengthen the grain? What if I just use nice plywood?

I was given a 42uF 12KV oil capacitor. Any suggestions for having some high tech fun with it? Answered

It's rated for oscillatory currents, pretty old, but it is in good cond. electrically. I can easily and safely charge and discharge it. The thing is, it was free, and I suppose I couldn't turn it down. Now what? The highest voltage I would possibly need a filter cap for is 4500 for an amplifier, so that's out. The "oscillatory currents" rating makes me think it was for energy storage and high frequencies. It is likely from LANL surplus. Can crusher? disc launcher? I'm mainly interested in suggestions for projects that will focus on a fast discharge and high peak power levels, and do not require a lot of additional items, but I am open to any decent ideas.

Ever Saved a Motorcycle from the Scrap Heap?

I come across old unloved bikes alot. Somebody got all excited and bought a real beauty. After a couple of years, the newness wore off, and the old bike spent 20 years in the barn rusting away. Lots of times these old 2wheelers can be had for the asking, or at least for scrapyard prices. I love to save these old bikes from certain destruction at the hands of weather/recyclers/inexperienced tinkerers. I'm working on an ible about salvaging these old machines. Anybody else out there ever saved a classic/junker from the elements (or even worse, the crusher)? Any tricks you know for bringing one of these would-be stallions back to life?

Too much scrap from salvaging! Recycling ideas needed

Hello fellow instructabilians, I love the site and the community here! I have been salvaging and collecting a lot of items from dumpster diving, hard waste / rubbish collections etc that I have used to extract components like motors, electronics, glass etc. But as always, after extracting what I need, I end up with a mass of plastic, wood, metals, and some other random materials that have no use. I would love to find a way to crush the bigger plastics, melt the metal ( if alloy ), shred the wood, and melt down the glass. Of course, you are able to make some big crushing machine, but this is why it is under the green section. I am trying to find a sensible way to rid of all this excess junk, with a means of being able to teach others to do the same thing. Our bins are very small, the tip is very costly now to even take junk, rates are going up, please, someone throw some ideas of any sort to help me find a system / make some green 'machines' etc. I hope you understand, and just a quick mention, I am dealing with at least 6m square of this useless junk that needs to, and can be sorted if there was a way. I may even need to get my local community involved, like a pre-recycle event.. I dont know. Help. :( I guess a crusher, or something to deal with the largest of materials ( like CRT screen plastic outer shells ) would be a first step.
