Introduction: Mens 5 Cent Ring

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. Drill through the premarked center. You can progressively drill a bigger hole until it will fit on the mandrel your using. Or, you can just use a 3/8 spade bit like did. I used a pry bar as the mandrel.

Step 3: Hammer

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 at a 45 degree angle.

As you hammer rotate the mandrel and apply slight pressure towards the anvil. The ring will form a cone shape. Continue to hammer until the cone forms a cylindrical ring.

Once you have the ring shape you can continue to hammer causing the ring to expand in diameter. This is where you check it against the finger measurement it's being made for.

Important. As yor move the ring up the mandrel, flip it around. This helps to make the cone a cylinder.

Step 4: Mount the Ring

Find a socket bit just barely smaller then the ring. If you can't find a socket that's just right you can use a smaller socket and use something to wedge between the ring and socket. I use parachord when I need to.

After you press the ring on the socket, use a nut and bolt and secure it through the female end. The protruding end of the bolt will be used for mounting in the drill press.

Place a smaller coin under the socket while you tap the ring on. This leaves an even spacing to true the edges up.

Mount the assembly in the drill press and spin it round. You will shape the bottom side first.


 

Step 5: Shape

With the assembly spinning in the drill press, use progressively finner sand paper to make the ring it's final shape. I start with 80 grit, then 400, then 2000.

Spray the 400 and 2000 grit sand paper with water. This prevents the sand paper from getting clogged with metal particles. Again, this gets HOT! And don't breath the metal dust.

Flip the ring as needed. Use polishing compound to buff it to a shine. Now that the outside is nice, time for the inside.

Be careful not to mar the ring. Use the wood clamp to remove the ring from the socket. Flip the ring over and press it back onto the socket. Make sure you use a soft work surface when you hammer the ring on and off. I used the clamp it self.

Step 6: Smooth the Inside

Take a larger size drill bit and tape a piece of 1000 grit sand paper to it. Roll the paper around the bit with the direction of spin for the drill press. Smooth the inside and any sharp edges.

    i know you have a metal lathe. If you can work it at all like a wood lathe, you. an turn a slightly tapering piece of wood a good foot long that at the smallest is like a size 4 ring and at the largest close to a 15. This becomes your new mandrel. if you have trouble with the ring slipping you can put some tape where it fits, then slide the ri g over the tape for a tight fit. that's how i sand the wooden rings i make.

    This is really cool! I want to try making one but I am worried that my lack of patients will have me turning out with a less than satisfactory product. What are modern nickels made of? I figured they were some kind of alloy.

    I think they are an alloy of nickel and copper.

    they're made of a nickel copper alloy, thats true. ive noticed that it turns my finger green as the copper oxidizes. is there any way to prevent that? i was thinking maybe covering the inside part with solder then polishing it again. would that work?

    Hi,
    You could try using the sacajawea dollar coin.
    It "looks" golden, but the gold is is only on the outside, which you sand off. I read the inside is a higher grade of copper/nickle alloy (90/10) and should resist tarnishing better.
    Sounds almost opposite, being 90% copper, that it should tarnish less, but I think the higher copper content makes it more durable.

    On guns, you put "gunstock oil" on the barrel, which you could try here. Or you could use boiled linseed oil, and wait until it hardens and gets very dry. This won't last forever, but it is what gets put on steel gun barrels to protect the blue/black, so it could work well.

    Little late on the ball here, but for the best results try to find silver quarters, they were 90% pure up to 1964 for the US... uhh, Canada is a wee bit more complicated see the following chart [http://en.wikipedia.org/wiki/Quarter_(Canadian_coin)]
    Silver is soft and easier to work with, also doesn't leave marks on the skin.

    I made one like this using a pre-64 quarter. I messed it up a bit at first, because I was stupid, but I managed to salvage it, and it turned out pretty nicely. I'm definitely going to try again soon!

    I would like to make one for myself that is made from a pre 1964 quarter...should I drill a smaller hole and then form it into a cone? I am worried that If i drill a large hole and then hammer it it will be too large for my finger

    This was great!! I just read this like 3 hours ago! and Have a Really Cool Ring....going to make another one!! This was a great instructables with great instructions!
