Up until recently, it was nearly impossible to get very small sized coin rings fro the larger coins, while being able to preserve 100% of the coins’ detail…. until now!
There is a new technique called the “Swedish Wrap Method”, and it has truly revolutionized the way that larger coins are made into the smallest-sized coin rings.
The general idea is that AFTER you’ve folded over your larger coin, (such as the American Silver Eagle, Morgan Dollar, Challenge Coin, etc), you would then anneal the coin, wrap it in teflon tape, and then using different size-diameter brass push rods, begin to compress the coin FROM THE REEDED EDGE down into a series of shallow reduction dies until you achieve the shape and size that you’re looking for.
After having prototyped several combinations of die heights and inner wall pitches, (tapers); I went with this particular Swedish Wrap combination because this really achieves the “sweet spot” between both die height and inner wall pitch: not too short, not too tall… not too steep; and not too shallow. This particular combination produces some of the best and most consistent results, while allowing you to be in better control of your work.
My complete Set that I’m offering folks at my Shop Page comes with THREE 1.5” tall ”Swedish Wrap” Dies made of hardened stainless steel, 4 Brass Push Rods that are all double-sided (for a total of EIGHT different outer diameter-sized options when extruding), 2 rolls of Teflon thread tape, and a *BONUS* piece of tough impact-resistant urethane pad that you can use on the ends of the push rods to both protect the reeded-end of the coin, and the brass push rod end. (You simply take a pen and trace each of the 8 outer diameter push rod ends onto the urethane pad and then cut them out to end up with 8 different-sized urethane “discs”).
* A major benefit that this combination of die height and inner wall pitch offers is the option of bottoming out the coin ring in the first die, and then switching to the next smaller-sized Swedish Wrap die without having to push the coin ring all the way out the bottom of the initial die. You can, however, extrude the coin ring through the bottom of any of the three dies if you choose to without damaging the coin ring’s detail; as each die has been machined with a unique beveled relief at the bottom that allows for this process.
* Another major benefit to this Swedish Wrap Set is that you only have to use ONE brass push rod working through the die to bottom out your coin ring in any of the 3 dies in the set. This eliminates the extra step as well as the potential for slipping when stacking multiple pushers on top of each other.
This complete 3-die Set offers a total of 4.5″ inches of workable inner die wall to compress coin rings; and it gives you the full range for extruding coin rings all the way from nearly 1.450″ in outer diameter, down to just .765″ in outer diameter!
*** SWEDISH WRAP METHOD STEPS: ***
After folding your coin ring (using the regular Universal Reduction dies), find the correct diameter brass push rod that covers the majority of the reeded-end of your coin. After annealing and wrapping the coin in Teflon thread tape, you place it into the appropriate sized die, with the reeded edge facing UP. Next you place the appropriate-sized urethane disc onto the top of the reed side of the coin, and place your push rod on top of that. The urethane creates a protective barrier between the two metal surfaces and helps to preserve the detail of the reeds as well as the brass push rod end.
Begin to compress (extrude) the coin down the die, pulling the coin out after every press to re-anneal and re-wrap the coin, and when necessary; flipping the brass push rod over to the next smaller diameter size to continue compressing the coin down the die.
Starting with the LARGE (marked 1.4”) and followed by the MEDIUM (marked 1.2”) Swedish Wrap dies, I have been able to reduce American Silver Eagles, Morgan Dollars, and even Challenge Coins down to a size 9 while only BOTTOMING the coins out in the Medium (1.2”) die.
The “SMALL” Swedish Wrap die in the set (marked 1.1”) can be used to compress the Half Dollar-sized coins down to roughly a size 3.5 with full extrusion, and can also be used to further compress the larger-sized coins such as the American Silver Eagle, Morgan/Peace Dollars, Challenge Coins, etc., down to a tiny size 1! As with the larger Swedish Wrap dies, you can then “tuck in” the edges of the coin using either the Universal 17°, 20°, or the 25° “Fat Tire” Folding and Reduction Dies also found at my Shop Page for a rounded-look while bringing those larger coin rings down to a size 00 – 000.
The SMALL Swedish Wrap die (marked 1.1″), can even be used to compress US Quarter-sized coins down to a size 4 when fully extruded out the bottom of the die. Then using the smaller reduction die of 0.7″ x 0.8″ (that I also offer at my Shop Page), you can further reduce US Quarter-sized coins to your final desired size!
Depending on the size and look that you’re going for, you can now either:
1.) Expand the thinner cut-side of your coin ring to match the outer diameter of your coin ring on your ring sizer machine for a “straight-walled” look;
2.) After Step 1, you can then further reduce the ring size by “tucking in” the edges of the coin using either the Universal 17°, 20°, or the 25° “Fat Tire” Folding and Reduction Dies (also found at my Shop Page) for a rounded “Fat Tire” look; or,
3.) You can continue to compress the coin ring further down the Swedish Wrap dies to achieve an overall smaller size.
FOR THE “STRAIGHT-WALLED” COIN RING LOOK:
For those wanting the “straight-walled” look, I like to compress the coin ring using my Swedish Wrap dies until I get to anywhere between ¼ size to a ½ size BELOW my target ring size. Then using my deburring tool, I will remove the appropriate amount of material from the INSIDE of the thicker reeded part of the coin until I achieve my proper target size. Next, I expand out the thinner cut-side of the coin ring on my ring sizer machine until the sides of the coin ring are straight.
FOR THE ROUNDED “FAT-TIRE” COIN RING LOOK:
For those wanting a rounded-look to their coin rings, I will compress (“Swedish Wrap”) the coin to anywhere from 1 to 3 sizes OVER my target size. You can then use your appropriate-sized Universal 17° or 20° die to “tuck in” the sides until you achieve your final ring size, or you can use your 25° Fat Tire die to achieve an even more rounded “Fat Tire” look.
PLEASE KEEP THE FOLLOWING IN MIND WHEN USING THIS TECHNIQUE:
1.) TAKE YOUR TIME, especially when first starting out. I recommend Swedish Wrapping’ a few rings out of clad coins to get familiar with the process.
2.) Make sure that you anneal your coin OFTEN, ideally after every press or two. Doing so will make the process easier.
3.) Use a TON of Teflon pipe thread tape, and make sure to re-wrap your coin ring after each press and anneal. A 10-pack of the Teflon Tape can be purchased at HarborFreight.com for 2 dollars.
4.) Make sure that you firmly press the freshly re-wrapped coin ring and make sure that it is seated evenly in the die before pressing.
5.) Press SLOW and make sure that the brass push rod covers the majority of the reeded portion of the coin. If it doesn’t cover enough of the reeds, the push rod could slip as you’re compressing it, possibly ruining the coin ring. You can fix this issue by placing the coin ring, (reeded side DOWN) into either your Universal 17°, 20°, or 25° reduction die to slightly shrink the outer diameter of the reeded side until the brass push rod better covers the reeds.
6.) Make sure that you don’t over press the brass push rods down the Swedish Wrap dies, especially when using a hydraulic press. After some practice, you’ll feel the resistance of when each push rod bottoms out in the dies.
The tiny-sized coin rings can be incorporated into charms on necklaces, (see the 3rd listing photo for reference), bracelet charms, or even earrings. The possibilities are nearly endless!
