I have combined my knowledge and experience of metal casting with my access to a laser cutter to create a truly one of a kind engagement ring.

I am a metal worker at heart, and my fiancee is more of a wood person. I wanted to create a ring that would combine our two elements and have them connected seamlessly. Using pewter for its low melting point and walnut wood for its density to protect it against the heat, I was able to cast a full metal inlay directly into a wooden ring.

I understand that not everyone has access to a laser cutter. The same techniques shown here could all be done using a scroll saw and some carving tools; it would just take a little bit more work.

Step 1: Laser Cutting Your Ring Blank and Mold

I have provided the Illustrator file of the ring casting box for free use. Adjust the file according to the ring size you need and cut all the pieces provided in the file. Please read the following steps before cutting.


Creating your ring: Use a ring sizer to figure out the ring size of your fiancee or whoever will be wearing the ring. There are lots of ways to do this without a ring sizer, you can find a handy guide here. Build a ring profile with the appropriate inner diameter and an outer diameter. I made the ring about .33" thick to allow for a deep etch. I cut the ring blank out of 1/4" walnut so I would have enough thickness to engrave.

Create a tightly fitting mold: Cut a matching casting box from the same type of wood as the ring to guarantee a matching fit.To compensate for the kerf of the laser I cut the ring first, then I measured it with a pair of calipers (in this case it ended up being .98" from a 1" ring), and then I adjusted the file size for the ring casting box accordingly.

Side panels: You can cut out the side panels or find some scrap wood that will fully cover both faces of the ring casting box.

You have completed your casting mold and ring blank!

A big THANK YOU! for everyone that voted for me in the wedding contest! I'm especially proud of this project and I'm delighted so many people enjoyed my technique. <br><br>This is an invaluable community to be a part of, thanks to you all!
<p>Congratulations!</p>
<p>Wonderful job, you got my vote.</p>
<p>I really like your Instructable. However, can I recommend using a picture of the finished product for the cover picture? It would definitely get you a lot more views/votes. Keep up the great work!</p>
I thought a process picture would help show the unique quality of the project better. It's also been hard to get the ring back for pictures after I proposed but I've been working on getting some nice finished shots of the ring that I can post. <br><br>Thanks for sharing your thoughts! :)
<p>Awesome project! The thumbnail looks great, but one that has more light would look better :)</p>
<p>Love the new cover shot!</p>
<p>That is amazing</p>
<p>That is amazing! Can't wait to try this.</p>
<p>Very nice. Thanks for sharing this idea. You've got my vote.</p>
<p>Super excited to try this one out! It looks magnificent!</p>
<p>Very nice - the ring and the instructables. It gave me a few ideas for other projects and so I Google'd to see if bigger castings could be done in wood, wether inlays or molds. Here's an older YouTube with an example, along with aspects of safety :</p><p><iframe allowfullscreen="" frameborder="0" height="281" src="//www.youtube.com/embed/pqTDxf7x8ew" width="500"></iframe></p><p>Now I really want to give this a shot ... Thanks CrazyClever, you've got my vote.</p>
I'm happy I've inspired you, thanks for the vote! Good luck :)
Awesome job!!<br>You've got my vote
