How to dap and dome metal jewelry

Cymbals of Happiness bracelet by Sondra: stamped, textured and domed copper and brass disks make a tinkling charm bracelet.

It took me awhile to accept dapping as a real word.  Even now that I am obsessed with dapping every flat piece of metal that crosses my path, I still find the term awkward. Spell check, ignoring the facts as usual,stilldoesnt believe.

In jewelry making, dapping simply means taking a flat piece of metal and curving it into a dome with special dies and punches, called adapping set. The dapping block (or die if you prefer) has a series of concave impressions that correspond in size with the dapping punches.

Rings & Things 69-199 dapping set by Eurotool, and a variety of flat and dappedmetal pieces.

Simply place yourmetal piecein the block and use a hammer (preferablybrass) to repeatedly tap the punch into the metal. I saytapbecause your goal is togentlybend the metal into a smooth, even curve. If you just whack as hard as you can, the metal wont shape up evenly.

The entire piece of metal needs to fit inside the impression, not sit on top like in this picture.

Here the metal pieces are inside the impressions, ready to be dapped.

Another tip: dont hammer straight down on your metal. Hold the dapping punch at and angle, and tap tap tap with your hammer, turning your metal after every few taps to ensure that it is shaping up nicely.

For best results, keep rotating the die and the metal.

As you dap (tap, dome, whatever!), the height of the metal piece increases, while the width decreases. So after youve dapped as much as you can in one impression, you can move the metal into the next smallest hole and dap it with the next smallest punch to get a deeper dome.

Doming adds a professional quality to your work. Even just a slight curve instantly makes a metal disk reflect more light.

Brass, copper, aluminum and sterling silver are all excellent soft metals to dap (most of my images are ofraw brass blanks). Even copper coins can all be dapped, although coins are thick and will require you to apply a bit more muscle.  If you want to stamp, texture, punch holes, or otherwise adorn your metal (and you will!) do all thatbeforeyou dap for beautiful results:

Dapped pieces can be layered too, like on my copper and brass ring. (See bottom of this blog for tips about making this ring.)

One word of warning you might need to upgrade your photography equipment to get good pictures of your dapped jewelry! I think the only way to get a clear picture of Mollies God Save the Queen necklace would be to use a professional light box. The domed Canadian penny is amazingly reflective. Since my photo-editing software lacks a rhinestone-reflection remover tool, this is as good of a shot as I could get. Believe me, the necklace is stunning in person!

A domed penny, brass filigree and snippet of rhinestone chain, all soldered onto a brass disk, forms the centerpiece.

I know you are quicker on the uptake than my computer: add dapping to your jewelry-making vocabulary today! ~ Cindy


Weve gotten a bunch of questions about Cindys copper and brass True ring above, but she has moved away, so Ill do my best to answer. The ring uses only 3 parts:

Texture the copper washer usingthis technique, or simply give it a nice hammered texture with achasing or ballpein hammer. Stamp true on the disk followingthese metal stamping instructionsorthis metal stamping article. Then dap (dome) the washer and the brass disk, and glue them into the bezel ring with your favoriteadhesive. Cindy usedE-6000.  ~Polly

Very Cool Dave! Gonna order the wood one. Will that work as well? Tight budget 🙁

Hi Debbie! The wood one also works you wont be able to get a really deep dome with it, and you would have a tough time doming thick items (like coins), but on the plus side you can use slightly larger disks than with the metal set. Have fun!

Thanks Cindy. Most appreciated. I will also get the other one as the money pours in from my sales 🙂

Recently purchased a wood one until I can afford a better model. Thanks for the tips!

Awesome! Thanks for the great tips, Cindy!! I have a wood dapping set & am adding the R&Ts metal dapping to my wish list. Got my R&Ts brass discs so I am ready to dap-a-dee-doo-dah now 🙂 I wasnt sure whether to stamp, punch, texture before or after dapping, thanks for clearing that up!

Great tutorial and ideas! I am addicted to my set, constantly liking for new things to done.

I have a hard time wrapping my brain around the word:) Ill stick with doming ~ it sounds prettier!

Any chance of getting some hints on how to make that beautiful ring??? Thanks for this great post!

The ring uses a round bezel ring (51-205-02-1) as the base Id been using the rings with resin and by chance discovered that dapping copper ring/washer blanks (44-780-25 or -26) made them the right size to squeeze into the bezel. The brass disk and copper washer are glued to the ring base with E-6000.

I am looking for instructions on dapping bottle capsIm not having any luck. My caps finish askew and scratched..there must be an easier way. Thanks so much for any help.

Like Susan, I am after information on dappling bottle caps (also would you recommend a wooden or a steel kit for the purpose?)

Hi Rebecca! The darn spam filter must have eaten the reply I posted for Susan. Sorry about that. Anyway, for dapping bottle caps, I actually recommend using both the wooden and metal dapping sets! The reason is the bottle caps are too big for the metal set (at least for mine) and so I like to start with the wood set and then move to the metal. Steel on steel can mar the surface, so it takes practice to hit them hard enough to reshape them but not so hard that you ding them up. Hope this helps! Happy crafting 🙂

I would love a tutorial on how to make the penny necklace :0)

Thank goodness for your blog post explaining what dapping meansI looked it up and apparently it meant something entirely different in colloquial termsnot safe for work, for certain. Thanks again for the article!

Oh no! Thats funny Im glad you found our blog to explain the jewelry definition. Im at work (plus a bit worried about what Id find) so Im NOT going to go look up the meaning you found. :/

Please,which is the material needed to make this bracelet (first photo) and ring (true)?

The Cymbals of Happiness mixed-metal bracelet was made in our Spokane Showroom. Several customers helped to create each of the cymbals!

Here are the parts (materials), with instructions:

1) Cut the chain (40-099-48-7) to the size of bracelet you desire. Attach a clasp at one end.

2) Using a two-pound brass hammer (69-345) and adisk cutter (69-106), create a variety of cymbal sizes (or flat disks). Or,metal shears (69-230)will cut24-gauge brass (64-990-24) and copper (64-980-24) sheet metalas needed.

3) Using theEurotool punch (69-235), make a hole in the center of each cymbal. The punch can also be used to create interesting holes in the cymbals as well.

4) Texture each cymbal before dapping using amulti-head hammer (69-344).

5) Dap each cymbal using thedapping set (69-199)and a two pound brass hammer.

6) Wire-wrap each cymbal using adotted-flower head pin (37-482-04-ap). Use an assortment ofdaisy spacer beads (49-954-04-ac, 49-954-05-ac, 49-954-06-ac, etc.)on the top and bottom of each cymbal, as needed, to stabilize the wire wrap.

8) Attach cymbals to chain in a random pattern usinglarge jump rings (37-178-7).

9) Wear and enjoy the tinkling sound and compliments!

I believe the ring was made via a similar process. The bezel that the parts are set in, is:

And instructions for stamping true are at the How to Make a Metal-Stamped Charm technique sheet in our Resources page:

Please let me know if weve missed anything!

Actually, someone just reminded me that we have more details about the ring here:

Please, Where do I find the tutorial and the material to make the photo ring? Wiaiting and thank you!

I added some brief instructions for the ring, to the end of the blog. Please let us know if you have more questions! ~Polly

where can i purchase the equipment needed to dome coins, and approximately how much do the necessary items cost? i have three u.s.a. coins, a liberty walking half dollar and two mercury dimes that i want domed and small rings soldered to the backs so they can be attached to a hat. if the equipment is very expensive, can you recommend someone who can do this work for me.

In the blog above are links to each of the tools suggested. You will need to measure your coins, and click into the links to see which size tool sets will work for your coins. Plus it sounds like youll need to invest in soldering supplies as well, unless you already have those.

Not knowing what part of the country (or world!) you are in, its tough for me to recommend someone. Ok, it would be tough even if you were here in Spokane! =)

Here are a few suggestions: Call rock shops (or lapidary shops) in your area, and ask if they have someone on staff who can dap/dome and and solder. Its a bit of a long shot, but worth a try. Or call jewelry-repair shops that work on coins and silver (not just gold it has a MUCH higher melting temp). Or when the weather supports local higher-end arts crafts shows, walk the show looking for silversmiths or other jewelry-makers and ask if they can dome/dap your coins and solder loops. Another possibility is to google your town name + handmade jewelry, looking for jewelers. Skip over wire-workers and bead stringers unless they ALSO have designs you can tell are soldered or otherwise metal-worked.

Good luck; it can be a challenge to find jewelry-makers who are willing to take a risk on your treasured coins / keepsakes, and it can be a challenge to find custom/repair shops who have experience working on materials other than karat gold or platinum.

You finally showed me the set of tools Ive been looking for AND the name. One question: What do I need to stamp letters in like youve done. I have googled everything and all I can find are expensive tools. Your ring is great and I just want to add that to my growng jewelry tool box

They are alphabet metal stamping sets ( and are available at a variety of price points. Very cheap sets from Harbor Freight frequently have missing (and doubled-up!) letters in their set. Very expensive sets are either unique fonts that arent in high production, or exceptional high quality shaping and tool-steel or simply overpriced. =)

I hope in the above link you find a font you love for a good price thats our goal; we try to provide good quality for a reasonable price, rather than go for the extremely cheap or the extremely expensive.

Thank you for this post, great information.

what size is the dapping tool thats used for a standard beer bottle cap?

Its fun! And easier than you might expect. The tool set looks a little daunting at first but one you get a few tips (like the ones in this blog), you find out its not hard at all!
