Step 1: Find a Cart

The shopping cart. Visitors to the United States are astounded by our shopping carts, which are the largest in the world. Also amazing is their abundance miles from the stores from which they came. No homeless person will ever want for a shopping cart.

The best selection of shopping carts will be found near a "redemption center" where homeless people get paid for recycled soft drink containers.

Step 2: Through Destruction Comes Creation

Look for a shopping cart that really wants to be a chair. You won't have to cut or bend much to release the inner chair.

Let's get started. Pound, twist, and pull out the retaining rods and remove the front bumpers.

Save them. One can be used later to cover the front edge of the seat

Step 3: Plan Ahead

Plan the cuts you will make in the wire basket. Blue tape marks where the cuts will be made.

Iron origami magic will make nice arms from those weird projections. This particular cart had very high sides,

so I thought I'd try a new style of arm bending. I've been making these things for a couple of decades, but there is always something new to try.

Step 4: Cut It Up

I'm using a sawzall to cut along the lines. A hacksaw, bolt cutter or angle grinder work well also.

The right chair design will require few cuts. The chair is already there. You're just releasing it.

Step 5: (Neat Trick)

Here's how to keep your power cord from pulling out of the extension cord.

Step 6: Bend the Arms

Clamp a couple of boards to make the crease of the bend happen where you want it.

This was a tricky diagonal bend and it took a lot of leverage from the long sticks to make it happen.

Note that bending the metal work-hardens it. It's very difficult to change if you bend it wrong.

Step 7: Curve the Arms

For the next bend I made a tool from pipes and bolted it onto the protruding arm piece.

Step 8: Clean It Up

Clamp a couple of boards on the front edge of the chair and bend it down.

File all of the burrs off the ends of the cut wires.

Step 9: Finish the Front.

Clamp a couple of boards on the front edge of the chair and bend it down.

Step 10: Alternative Method of Finishing the Front Edge

Carve the inner projections of the bumper so they'll fit over the wire and
slide the retaining rod through the holes.

File all of the burrs off the ends of the cut wires.

Step 11: And Now You Have a Chair.

Two different chairs, two different styles. Don't leave them outside though, because they will rust.

Sorry dude, I think you did a fantastic job with this but I use a wheelchair and I would not like to use this for more than 5 minutes. It looks MEGA UNCOMFOTABLE. Cool idea though!

P.S Am trying to make an "awesomechair" with ipod speakers, snack compartment, dvd player and a fold out table. Any ideas???

How about a hand crank bike unit like this one I saw in Nicaragua?
Or hand cranks on the wheels like that "big wheel" plastic trike competitor,
"the thing" I think it was called?

I would sure love an 'bile to make a hand-crank trike! I have knee & hip problems, but would love to be able to cycle (and I never have ridden a bike--long story short, klutz genes)--it's pretty good exercise. My hub is pretty handy, once you get him going. So, were those ones made with shopping-cart hybridization, or what? The picture looks like the back part is a wheelchair?

There is cool and then there is F'n cool! I once mounted a kitchen sink in a shopping cart......... I thought that was cool but the security device beeped sporadically and scarred me!

This is great! We always make jokes about the carts laying out on the side of the road being asleep after a wild party they had:) Hey, its the little things in life.

I think the doge would have enjoyed the chair... he could have wheeled around under the papal chapel enjoying the frescoes with the pope on his lap. I got to ride in one back at miters long ago, it was cool. Great video!

Where do you get a used shopping cart? I mean, if you just took one, you'd be, well, stealing. Where did you get such a special little girl? She's soooo cute!

Your point is? Walmart is making enough profit already, they can afford a few missing shopping carts.

Walmart actually doesn't make much net profit. There is so little profit margin between what they buy an item for and what they sell it for that the only reason they make a profit at all is because of how many stores they have. If they only had one or two stores open, they'd never make it. This is why walmart stock is considered "high risk." Most of the gross profit they make is used up in overhead, such as property taxes, employee wages, and replacing stolen shopping carts.

Just because a company makes "enough profit", doesn't mean that stealing from them is right.

Don't worry, none of these shopping carts are stolen. However all the land seen in these photos and videos is stolen. It is the U.S. after all.

once again, the immoral vs illegal squeaks in here... the US was , from time before records, acquired through conquest. One invading group, from the other... MOST of the current us was purchased with cash. :-) the rest of the post-13 colonies falls under the 5th amendment provision for "private property be taken for public use, without just compensation" said compensation being, at the time... land in the form of reservations. Not to say it's right, just the way things were. Good to know that the carts weren't stolen though :-)

Native Americans never felt that they "owned the land in any way.

Isn't the Fifth Amendment the right to not incriminate yourself? As in "to plead the fifth"?

That's only PART of that particular amendment.

"Amendment 5 - Trial and Punishment, Compensation for Takings. Ratified 12/15/1791.

No person shall be held to answer for a capital, or otherwise infamous crime, unless on a presentment or indictment of a Grand Jury, except in cases arising in the land or naval forces, or in the Militia, when in actual service in time of War or public danger; nor shall any person be subject for the same offense to be twice put in jeopardy of life or limb; nor shall be compelled in any criminal case to be a witness against himself, nor be deprived of life, liberty, or property, without due process of law; nor shall private property be taken for public use, without just compensation."

Yes that is part of the 5th, but here's the full text: Amendment 5 - Trial and Punishment, Compensation for Takings. Ratified 12/15/1791. No person shall be held to answer for a capital, or otherwise infamous crime, unless on a presentment or indictment of a Grand Jury, except in cases arising in the land or naval forces, or in the Militia, when in actual service in time of War or public danger; nor shall any person be subject for the same offense to be twice put in jeopardy of life or limb; nor shall be compelled in any criminal case to be a witness against himself, nor be deprived of life, liberty, or property, without due process of law; nor shall private property be taken for public use, without just compensation.

Ohhhh it's wrong to steal 0.000001% of a massive company's stuff, watch out for karma man. I'm crying now. Let's all stop stealing and go to church to worship our non-existent gods.
