Make a wallet out of duct tape? How 1992. I remember learning how to make a duct tape wallet at scout camp in 1992, and extended that lesson to a duct tape tie which I wore to any and all high school presentations or performances that required an increased level of attire. Needless to say, I had no problem avoiding sexual contact with the opposite gender.

Duct tape wallets are non-optimal. The nature of the adhesive used on duct tape results in a wallet that will slowly slide apart based on the forces input to the wallet by your ass. After a year or so, depending on the ambient temperature of your location, the wallet will be falling apart and you will be building a new one. Besides, who needs all those pockets, a full length cash slot or other "wallet" features? In today's modern, RFID, credit-ready, cash-poor society a money clip with credit card and drivers license storage is truly the best wallet you will ever need. Any more storage and you will tempted to store receipts, ATM slips, business cards, and other sundry items in the wallet until you have a full blown case of "Costanza Wallet".

Enter the Innertube Wallet. As a Maker, geek, or otherwise shunned cheapskate, you doubtless have numerous blown bicycle innertubes, a few sheets of rusty 22 gauge steel, and any number of DOA hard disks and their attendant magnets. With such materials and a boundless enthusiasm for turning interminably stored junk into stuff you don't need, I present the bitchin' innertube wallet to solve all your wallety needs.

Step 1: Assemble Your Materials

The first step to creating your awesome new innertube wallet/money-clip is too assemble the materials required. The photo below should give you an idea. Feel free to substitute as needed.

1. Innertube. I recommend a mountain bike tube rated in the 2.1 to 2.6 inch range. Patches are optional but add a nice touch. You will need about 6-8 inches of innertube.

2. Thin steel sheet. I had a spot welded piece of 22 gauge sheet steel sitting around that was magnetic, and easily cut with my available snips. Rust is optional but gives street cred.

3. Metal snips. My brother-in-law has been borrowing my legitimate tin snips for about six months so I had to use my "super scissors" (pictured) which put the hurt on them. You should use real snips designed for steel. Since I had about 25 minutes to complete the project, I had to make due.

4. A magnet. I used a rare earth magnet from a broken 2GB Caviar HDD that I had sitting around. You will need something stronger than a fridge magnet, but the steel sheets will shield your credit cards from the super strong rare earth magnet for the most part.

5. Rubber cement. I used a bicycle tube patch kit to glue closed the assembled wallet.

6. Lastly you need some kind of file or sandpaper to smooth the steel pieces you will cut.

Step 2: Cut the Metal Backer

Once you have assembled the materials of your choice, you can begin work. The first step is to trace the outline of a credit card or other essential card onto the scrap metal with a pencil. A key consideration is to make the tracing about 1/8" larger that the card. This is so that the final metal cutout will stretch the innertube enough to allow your drivers license and credit cards to slide in with minimum of effort while allowing them to be retained securely. You will need to experiment with the specific number of cards and the innertube you use. For my purposes, a 2.1-2.6 inch tube with a 1/8" over cut metal backer was sufficient.

Once the metal is rough cut out of the thin steel, you should round the corners with your snips, and then smooth out the edges with a file and some emery cloth. I know I didn't include the file and emery cloth in the materials, but if you don't have something to smooth the edges sitting around your workshop then forget joining the smelly rubber wallet club.

Step 3: Start the Assembly

Once you have the main steel sheet cut and smoothed, the next step is to insert it into the end of the innertube. If you haven't cut into your tube yet, cut straight across the tube. Then jam the credit-card sized steel sheet into the tube as shown in the pic.

Once you jam this metal piece in, you will want to get the magnet ready for insertion. To do this, cut another piece of thin steel that is approximately the same size as the magnet. Make it square with round corners for ease of insertion. Smooth to edges and corners as previous. See pic.

Once you have the smaller steel sheet cut and smoothed, place your magnet on it and eyeball where you will need to cut the innertube to allow the magnet clip to hold your hard-earned cash. Leave a little (about 1/2" ) of extra innertube so that you can glue the innertube closed so that the magnet doesn't espace. See pics.

Once you have the innertube cut, then clean and scuff the opposing surfaces of the tube as it you were patching a tire. Use the scuffing tool provided in a typical bicycle patch kit. Insert the magnet on the metal piece. The key is to have the metal piece you inserted into the main body of the wallet to interact directly with the metal piece you cut for the magnet. The metal backing of the magnet is typically non-magnetic, so you will want the two steel pieces to touch, through the innertube to hold your cash while minimizing the magnetic field present at your credit cards. You will know if you have too much magnetic field at your cards if they stop working. You have been warned. I personally have had no problems.


Step 4: Glue It Shut and Hit the Town

Now that you have all the parts cut and prepped, it is time to put it all together and hit the town with your new rubber wallet. Take the rubber cement from the tire patch kit and squeeze it out on the scuffed portion of the rubber (see pic). Let it dry as detailed in the patch kit, and then press the two surfaces together. Be sure that your magnet and steel are inside before gluing. Once the glue is set, your wallet is complete. It can now hold all your Benjamins, Jacksons, and/or Washingtons. The image below is of $14 USD, four ones and a ten to illustrate the holding power of said money clip. In hand you can see the attractive nature of the innertube wallet. When spread artistically before my laser engraved cell the appeal is undeniable. In case you are interested, I laser engraved the design shown on my cell phone battery cover personally. I am also responsible for the misalignment between the design and the Motorola logo. I drew the Haida-inspired glyph. Contact me for more info or for the postscript file.
<p>Thank you for the laugh! I really do not need the bitchin' innertube wallet, but I did need the laugh. </p>
it's not the SIZE it's the strength. And No, Struckbyanarrow, you're wrong. ANY magnetic media can be erased and/or rewritten via magnetic field. Get your facts straight.
i would believe you but your name is Drstoooopid.<br />
&quot;i would believe you but your name is Drstoooopid.&quot;<br><br>struckbyanarrow you just made me wish Instructables had a &quot;like&quot; button! <br>Now that I think about it, that is a terrible idea, but nonetheless I would &quot;like&quot; this comment.
you're allowed to just say it - it's alright, i give you permission!
Me too!! Baahahha!! GOOD-TIMES!!
&nbsp;No no, mythbusters has proven this to be incorrect. &nbsp;you need a fairly strong magnet specifically made to alter these cards to change the coding within.
&nbsp;Also, I forgot to include that you would need a changing magnetic field, aka. AC current to affect any data on the card, therefore, you'd have to constantly swipe the card and change the magnets (magnetic field) direction. &nbsp;However, It's pretty darn difficult to do this with a simple, even a nd magnet.
&nbsp;the neodymium magnets from harddrives are pretty strong tho, wouldn't that be bad for credit cards, ipod /cellphone next to it?
The metal plate in the wallet side will shield the cards from the magnet if big enough and the magnet is not too strong.&nbsp; I have not had a problem with mine but your mileage may vary.&nbsp; I&nbsp;typically keep my drivers license and other optical cards closest to the magnet as a precaution.<br />
Yeah, has a magnet killed your credit card yet? Other than that . . . spiffy.
I presume you haven't seen Mythbusters. They tested large electromagnets against credit cards. The credit cards won.
Then I certify this as Awesome! (except for the name) Three cheers (and a favorite).
the name is awesome! who knew peple on instructables could get so uptight.... jk i love you guys lol
Haha how could the name be any better?
right?
So i guess it was magic that erased my Visa card and not the Wizard PK Ring? :)
I used to have an innertube wallet such as this one, but I ended up making a pretty sick-nasty leather wallet (complete with waterproofing and a logo. ;)
i just wanna say, that no matter what magnet, it WILL erase the credit cards, but only after multiple encounters.
Why not make the whole wallet bigger to fit the money in?
Because this is a money-clip style wallet which holds a minimum of cash. Cash is not king.
WHAAAAAAAAAAAAAAAAAAAAAAAAAT?!?! HOW IS CASH <strong>NOT KING?!</strong> MONEY IS THE BEST THING U CAN HAVE IN THIS C***PY ECONOMY!!!!!!!!!!<br/>
He means that cash isn't nearly as popular as plastic anymore
well, i meant along the the lines of making it wider. That way it doesn't wrinkle the bills along the side.
use a sewing machine to sew the middle section shut and on one end, put a snap unit from fabric store and fold over and you have a coin snap purse; use the open end for cc cards.
Oh <em>damn!</em> I got a terrible case of Costanza Wallet, and I even empty the darn thing on a fairly regular basis. I think the ATM stubs, old lottery tickets, receipts and Canadian Tire money all get funky and replicate in there. I'm sure I don't put much in the wallet, but sho' 'nuff, every few months, the wallet's all fat again, and it sure ain't fat with cash. Somebody help me...<br/>
Only you can prevent Costanza wallet. What are you saving those receipts for? Your credit card has all your transactions online. So does your ATM. And who needs to shop at Canadian Tire more than once a lifetime anyway? Ehh? The solution is within you. Recycle your receipts. Shred them if necessary. There is no reason to alter your spinal alignment by sitting on a pile of thermal paper printouts of your financial life.
But, I do remove receipts (occasionally). Moved the wallet to the front pocket twenty-odd year ago, specifically to prevent spinal problems. It's a mandatory for Canadian citizenship, to shop at Canadian Tire at least once a week. Being a Costanza involves a deep commitment to shirking individual responsibility. I think professional intervention, via some governmental or non-profit agency, must be required...
"It's a mandatory for Canadian citizenship, to shop at Canadian Tire at least once a week." lol awesomeness
You also gotta drink at least a case of Molson Canadian every week. I'm in constant violation of citizenship requirements, 'cuz Canadian is just such turrible, turrible beer. btw Thanks for quoting my text, and pointing out the grammatical error I made. It should have read just, "It's mandatory for Canadian citizenship..." Maybe that little "a" was snuck into my text by Mooninites, who stole the "a" from Neil Armstrong's "One small step..." speech, in 1969, and have kept the "a" in cryogenic suspension all this time.
Ah huh! Those little Mooninites didn't expect us to notice did they?
I thought you weren't aloud to say bitchin on instructables. That's bitchin!
nice instructable, but the very 1st word should not be a swear :-(
The first word is "Make".
No, I_am_Canadian means the title.
bad idea bro. The magnet will screw up your credit cards.
the magnets will do nothing at it has been proved that its impossible
"Needless to say, I had no problem avoiding sexual contact with the opposite gender" Haha. I thought that was funny. Btw, nice instructable.
Might as well just stick with the good old duct tape wallet. Some professional ones can be found on <a rel="nofollow" href="http://www.ducttaperevolution.com">Duct Tape Revolution</a>. <br/>
But money is bigger than it. If your sewing machine is up to it you could slice it and try some topstitching to hold it together. Or that tube glue, but that sounds like a worse plan. Or you could move to someplace with thinner money.
For anybody concerned about the magnets, just leave a small flap on one side of one end of the tube and add some fashionable button snaps. <a rel="nofollow" href="http://www.snapsource.com">http://www.snapsource.com</a> has a great selection of various colored snaps (including an assortment of greys and blacks). <a rel="nofollow" href="http://www.hidehousesouth.com/Catalog/R-H-Snapcap.htm">http://www.hidehousesouth.com/Catalog/R-H-Snapcap.htm</a> lists some of the traditional motorcycle-jacket style snap caps.<br/><br/><a rel="nofollow" href="http://www.denverfabrics.com/pages/sewinginfo/hsc-sewing-hints/sewing-snaps.htm">http://www.denverfabrics.com/pages/sewinginfo/hsc-sewing-hints/sewing-snaps.htm</a> talks about how to select snaps and some of the other basics while <a rel="nofollow" href="http://www.ehow.com/how_17167_apply-sew-snaps.html">http://www.ehow.com/how_17167_apply-sew-snaps.html</a> demonstrates how to apply no-sew snaps.<br/><br/>Ideally I'd love to find some gear plate button snaps to really round out the cycle style, but I haven't come across 'em yet.<br/><br/>Thanks for the tutorial.<br/>
thx for the tut. i will be making one myself
I don't know...I've had magnets erase my credit cards 2 or 3 times. Of course, these were 1.5T MRI magnets....
Dude! Hemingway is the best! Oh, by the way, sweet instructable.
definitely the most interesting wallet I've seen here so far... good job. My vote would go to you if I could vote.
You can vote!!! Click the "+" in the upper right!
Ah ha! Thanks! I did it!
Warning -- If you use a magnet in your wallet, and you use your laptop computer on your lap, DON'T PUT THE MAGNET/WALLET IN YOUR FRONT POCKET ON THE SAME SIDE AS YOUR COMPUTER'S HARDDRIVE! I did and it destroyed my hard drive. A couple of times. I was going crazy trying to figure out why my computers were dying. Oops.
The magnet with the two sheets of steel is not much stronger than the magnet in the original leather version I have used for years. (pictured in Step 1) The credit cards that have spent years in that wallet have had no ill effects, but only time will tell if the new magnet will wipe my mastercard. In the next version I may try and dig up some scrap stainless and make a mechanically clamping hinge instead of the magnet.
Literally had an unpublished version of this but it is different so may as well post it anyway.... good instructable
