Step 1: Mark the center

Center the coin in the carpenters square. Using a razor blade score a line in the center. Rotate the coin 90 degrees and score another line. Where the lines cross is the center. Now use a punch to mark the center. This helps you in the next step.  

Step 2: Clamp And Drill

Clamp the ring. Starting with a small drill bit, drill through the premarked center. Progressively drill a bigger hole until it will fit on the mandrel your using. I used a pry bar as the mandrel.    

Step 3: Start Hammering

Place a large hammer on a flat surface to serve as an anvil. Next, place the coin over the mandrel. Using a small hammer, hammer the edge of the coin. As you hammer rotate the mandrel and apply slight pressure towards the anvil. This hammering and pressure helps elongate the coin as it moves down the mandrel. As the coin stretches, check it against the finger measurement it's being made for.


If you want a thicker ring, hammer the edge at a 45 degree angle toward the mandrel. The ring will form a cone shape. Continue to hammer untill the cone forms a cylindrical ring. See the pictures on the last step.  

Step 4: Keep Hammering

Place the coin/ring flat on the anvil and hammer the edge. Eventually you will see the seam between the inner smoother surface start to close up against the outer hammered surface. Next, clamp the ring and use a rotary tool to grind out the seam. CAUTION!!! The ring will get hot!  Spray it with water before handling (notice the burn marks in the clamp). Wear safety goggles, not glasses. Airborne metal dust can fall behind your glasses.

I think this is illegal.

The charge would be defacing government property.

conformist

it's only illegal if you try to buy something with it after you've done this

I Have tried to make one of these out of a qaurter, but the quality was bad.

I was planning on making one of these (the slimmer variety) and twisting it into an infinity symbol to use as a necklace pendant. Would this work well? And is there anything in specific that you would recommend me do? Thanks

thanks for posting this its really cool, im working on one now. its not coming out as nice as yours. i didnt have a socket to put the ring to work on the inside so i took a scrap of plywood and drilled one hole the size of the ring halfway through one side and a hole slightly smaller through the other side to create a little ledge for the ring to sit on snugly to work on the inside. i colored the ledge orange in the attached photo to be able to see it better.

Awsome! Thaks for posting pictures. It's a help to everyone including me. Your ring is looking good. Keep in mind I ruin a whole bunch of material before I come out with anything worth while.

Wow, my mom just taught me how to do this a couple of weeks ago. She used to make them when she was a kid. But this is far more advanced. She gave me a nickel and sturdy spoon and said to hit it over and over again. It sounded like a cowbell on helium. Then you drill it and beat it some more.

So I don't think I fully understand- you put the coin at like, a 90 degree angle to the anvil- basically so they are side by side... Then you hammer the coin, on the face side / tails side against the anvil, and also along the edge of the coin? (smooth edge)
Mrballeng (author)  htonks3 years ago
What your hammering is the edge of the coin. As you hammer the edge it will flare into the ring thickness you want. Hammering it will it's through a steel rod also flares the inside.
I made 1 with a 48 50 cent peice, I drilled It 1/2" used a small Jewellers Anvil & Hammer & Tapped, Tapped, Tapped for about a year fairly often. I can still read under the folded edge most of Liberty, In God We Trust, Half Dallar, United States" Other side, etc. I left the Narfy "Hammered" finish.
Sooo.

This might be a stupid question... but what is a nickel made of? I'm trying to come up with a UK coin equivalent...
Since the later '30s, the US nickel has been composed of 25% nickel, with the remaining 75% being copper.

During WW2, the US nickels made had about 9% manganese in them, to act as a "filler" metal. The shortage of metals for the war effort made it necessary to put something in the mix.

Good luck !

Really you can use any coin you want. However, if the coin is one metal sandwiched between another (like the American quarter) you may end up seeing the inner metal if you sand too much.

By the way. Some one on my "VIntage Locket" instructable started up a conversation about UK coins and I have to say you guys have some awesome coinage.
rperki8 cook$3 years ago
The nickel is made of 75% copper and 25% nickel. The ten pence coin has the same composition.

UK ten pence
Nice Instructable. I did tried but tweaked it into a necklace. (not ring is act pewter using lost wax method. another instrutable) The ring around the heart is the nickel. thanks so much :)

Would you ever make one of those pendants and sell one to me? This looks amazing, but I just don't have the time or tools to make one.
Mrballeng (author)  BrandonZV3 years ago
Well, I'm not open for business just yet. If I start I'll be sure to let you know. Thanks for the complement.
Oh that's to bad, because sadly I don't have the tools, and I don't believe my father does either, to make these things. I just got done looking at your teardrop pendant and fell in love with it, I love things like this. Anyways, tell me if you ever do open for business or just want to sell some.
Thanks

I want these for myself and future husband! It seems like sizing would be haaaard.
Mrballeng (author)  scoochmaroo3 years ago
A while ago my wife's grandmother was taking some old jewely to the second hand store. I took a few pieces and melted them down into a golden blob. I hammered the blob into a disc and made a gold ring. On Christmas morning I found out it was too small.

So. I hammered some more. Polished. And now she wears it all the time. It's not as hard as you'd think.

If you post what sizes your looking for I'll post an instructable on getting a ring just the right size.

I love the pendent, I'm thinking of making one for my lady friend for valentines day, but I'm not quite sure i understand how to get the loops so small. If you could give a quick run-down or something that'd be awesome, and hopefully I'd be able to make one, i don't have anything too fancy, or jeweler's tools, just a file, hammer, drill and dremel.

For the benefit of ninjas everywhere I will post an instructable specifically for pendants. But in the mean time and because Valentines Day in creeping up on us, I will post a slide show on that specific pendant and explain with pictures.

Oh yeah also, isn't there a legality issue with this? If I do remember so, somewhere in some document it says you can't tamper or alter US currency? I was just wondering
Mrballeng (author)  theblorg3 years ago
Is it illegal to damage or deface coins?

Section 331 of Title 18 of the United States code provides criminal penalties for anyone who “fraudulently alters, defaces, mutilates impairs, diminishes, falsifies, scales, or lightens any of the coins coined at the Mints of the United States.” This statute means that you may be violating the law if you change the appearance of the coin and fraudulently represent it to be other than the altered coin that it is. As a matter of policy, the U.S. Mint does not promote coloring, plating or altering U.S. coinage: however, there are no sanctions against such activity absent fraudulent intent.

Yes, it is a felony to deface government currency.
Be that as it may, they don't seem too concerned with all those machines you find at tourist traps that will flatten you coins into some novelty badge.
Right it's only illegal if you try and change the coins to be fradulent and pass them off as another coin or form of currency.
All they're saying is if you cut the middle out and make that pendant, its not a nickel anymore and therefore you cannot spend it. Therefore you can use the penny pressers but you cant use your pressed penny to buy anything. So as long as you dont try to spend it nothing will happen
I made one ring and gave it to my wife, then she let my sister see it and I made another, The sister showed it to another sister and I made another and so on.
They all loved it and it never tarnishes.
Mrballeng (author)  timdgoodpaster3 years ago
Did you make it off of this instructable? If so, how'd it go?
I didn't make it from instructable. A man I worked with told me how to do it. The process is much like showen here.
Hi

Waaaay back in 1967 myself and other apprentices did something similar.

We used the newly introduced (Australian) 50cent coin. This was approx 30mm or 1.25" in diameter. We would hold the coin between our finger and thumb, with the edge resting on an "anvil", something heavy anyway. We then slowly rotated the coin as we hammered the top edge. This of course slowly mushroomed the edge to approx 6mm or .25".

We would then lay the ring flat on the anvil and lightly hammer the mushroomed edges to make them a little thicker. The center would then be drilled out with a reasonably large diameter drill and the remaining internal "edge" was filed away leaving a wide ring.

Nice job with your rings :)

Regards

Peter
