Easy Stone Crushing for Inlay





Introduction: Easy Stone Crushing for Inlay

For stone bits small enough for inlaying, you only need 4 items.

Step 1: Tools

Simple enough items. Hammer, 1.5" & .75" metal pipe cape, and a 1" wide pipe.

Step 2: Crushing

First, put the .75" pipe cap on the 1" pipe.

Second, put the stone that needs to be crushed into the 1.5" pipe cap.

Third, put the end of the smaller pipe cap on top of the stone and give the end of the pipe 1 good smack with your hammer. Watch out for your fingers if you miss!

Forth, shake the crushed stone a little in the larger cap so the bigger chinks of stone go into the middle of the pile. Give the stones another hit with the pipe and hammer like before, and continue this until the larger pieces are as small as you need them to be.

Step 3: Storage

After you've reached your desired stone inlay size, make sure to store the stones in a solid container and not a plastic bag. The edges of the stone will cut through the bag and leave a hole over time.

Hope this instructable helps you with my Bentwood Rings with Stone Inlay project!

Step 4: Experiment

Play around with stone sizes when you inlay. You might find you like a more powdery grit or larger chunks of the stone. Or maybe you like the individual pieces look over the solid color look. Maybe its the opposite for you. Try it out!

    Awesome idea! Do you ever have trouble with smaller particles of stone “escaping” or kind of ricocheting out in between the caps when you hit the pipe with the hammer? No matter how enclosed I try to keep everything when I crush stones and such, they always do that, and I’ve been desperate to find a way to keep that from happening.

    You've given me so much inspiration and the ideas are running through my head. I have some small Maine-mined Malachite and Tourmaline stones that were a gift from my father from about 45 years ago that I might use. I like both the tiny almost powdery bits and the larger pieces as well, so I just may try more than one!


    I would like to try making a ring and than putting it on the rotary atachment in my laser engraving machine and engrave the outside. There are so many possabilities. Thank you for sharing your ideas here.

    Sounds like a great idea, try it out. :)


    Can I use almost any wood or do you recommend any particular species? I was thinking of using either Cherry or maybe Maple.

    Are you using solid wood to make the ring or you doing a bentwood ring? Maple looks great when sanded and finished, and it is also very easy to work with. It will look great with some stone inlay.

    what a great idea, I really like your instructable
