In this tutorial, you will learn how to make a wooden ring using a CNC machine. Here is a list of the items you will need:

-Pencil

-Ruler

-Scissors

-Piece of Paper

-Block of Wood

-Sandpaper

-Wood Stain

-CNC Machine

-Design Software

-Coding Software(optional)

Step 1: Finding the Size of Your Ring

Items you will need for this step:

-Pencil

-Scissors

-Paper

-Ruler

Using your scissors, cut a thin strip of paper. Wrap the strip of paper around the knuckle of the finger you want to wear the ring on. Ask a friend to mark where the paper overlaps using the pencil. Next, measure from the start of the strip of paper to the pencil mark using your ruler, this is the circumference of the inside of your ring, for example, mine was 2 1/8 inches. Next, divide this number by 2π or 6.14, I recommend rounding your final number to four digits. This will give you the radius of the inside of your ring, for instance mine was .3382 inches.

Step 2: Designing Your Ring - Step 1 -

Things you will need for this step:

-Design Software

Using your design software(I used AutoCad), draw a circle with the radius you found in the previous step.

Step 3: Designing Your Ring - Step 2 -

Next, draw a larger circle around your first circle with a radius 1/4 inch larger than the inner circle.

Step 4: Designing Your Ring - Step 3 -

For the third step, draw two vertical lines starting at the left and right quadrants of the outer circle and ending even with the top quadrant.

Step 5: Designing Your Ring - Step 4 -

Next, trim the outer circle between the two vertical lines you just made.

Step 6: Designing Your Ring - Step 5 -

Finally, connect the two vertical lines with a horizontal line.

Step 7: Coding Your Ring

Things you will need for this step:

-Coding Software(optional)

Using your preferred coding software(I used SpectraCam), code your piece so that it is a third of an inch thick. You can also code it manually if you prefer.

Step 8: Cutting Out Your Ring

Things you will need for this step:

-CNC Machine

Using the code you made in the last step, cut out your ring in the desired wood material.

Step 9: Facing the Wood

If the wood you have is thicker than your ring, flip over your wood and face it to the end of the ring. When facing, start from the middle of where the ring is and work out. If you do not work from the inside out, the ring will pop out however it will not be completely faced.

Step 10: Sanding Your Ring

Things you will need for this step:

-Sandpaper

Using your sandpaper, smooth out your ring until you are satisfied with the finished product.

Step 11: Staining Your Ring

Things you will need for this step:

-Wood Stain

Using your preferred color of wood stain, apply a few coats with a Q-Tip or small brush. Let the ring sit over-night so that the stain can set.

Step 12: Finished Ring!

You're now all done! You now have a unique wooden ring that you can wear or display. Thanks for reading!

<p>Hi,</p><p>As an example of CNC'ing it's nice, but I'd think that it'd be extremely uncomfortable to wear - did you wear it for anything more than a test fit and if so, how did it feel?</p>
<p>It was comfortable, however if the ring is a tight fit I recommend sand the edges of the hole you put the finger in, because it might hurt a bit to take off.</p>
<p>Thanks for getting back, but I was more concerned with the 1/4&quot; between adjacent fingers - I have had heavy silver rings only 1/8&quot; between fingers which made them a bit uncomfortable to wear and forget shaking hands with anyone of those.</p><p>Using a suitable hardwood, it should be possible to get it much more inter-finger narrow without breaking.</p><p>Ebony, Pokkenholz etc. would be my choice and they don't need staining either, as they're beautiful on their own - and the smell when working these woods... Heavenly :)</p><p>Either way, thanks, I just have to build me a CNC soon and I'm always on the lookout for tuts around which software to use.</p>
<p>Oh okay, I agree with you that it was a bit thick between the fingers, however I didn't notice it being to uncomfortable, at least for me. I'm currently working on a ring with and 1/8&quot; between the fingers and not only will it be more comfortable, but I also think it looks better.</p>
<p>Looking forward to see the new &quot;baby&quot;.</p>
<p>Nice looking ring. Thanks for sharing your build. I hope we see more from you in the future!</p>
<p>Thank you! I'm actually currently working on a couple more ring designs, so keep an eye out!</p>
