Intro: Celtic Knot Bone Pendant - Triquetra PendantA couple of days ago I was making a Bone Ring and I had a l ittle piece of bone left over. With that I made a little Triquetra Pendant for my girlfriend. As usual, I usedsimple tools that anybody can have at home (no fancy lathe or CNCs).

Part of the work was already done for the ring that I made so I will just cite my other instructable: Celtic Knot Bone Ring

The close-up pictures were taken with a Pentax K10 D and a Tamron AF 90mm f/2.8 SP Di macro lens.The other pictures, with a Pentax SMC-FA 50mm f/1.4.

Step 1: MaterialJust one: a Bone! Beef bones are the bigger and the most suitable ones.

In Italy, especially in my region, we prepare a very good sauce with bone marrow. It is called pevarà (sometimes pearà) and it is made of bread, bone marrow, beef brbutter and a lot of pepper. In fact its name literally means peppered. So that is why I have those big bones lying around.

CleaningAn important point is the cleaning of the bone. After the cooking the sponge-like part of the bone is full of red bone marrow and that is not good if you want to work wit

the bone. The best way to clean it is to put it in the dishwasher!I was surprised, when I first tried this trick, how good it worked. It perfectly cleans every part of the bone and exposes the sponge-like part.

I put also some close-up pictures of the sponge-like part because it is too cool. Our bones have this kind of structure near the ends to make them light but strong.

Step 2: ToolsToy vise (I got it when I was a child but I still use it);Clamp;Very old drill;Drill bit for wood;Drill saw;Drill bit to scrape;Dremel;Dremel drill press (this is not necessary but very usefull);A selection of Dremel bits;Compass to draw the Triquetra (again, not necessary but useful).

Step 3: Cutting #1Now that we have everything we need let us start with the preparation of the bone piece. Be careful: wear eye protection!With the drill saw I cutted a rectangular piece off the bone, that incidentally is a leftover piece of the Bone Ring.

Image Notes1. Barely big enough to hold the bone

Image Notes1. The piece, ready to be worked on.

Image Notes1. Nice sponge-like structure

Step 4: Planning the TriquetraUsing a small compass I drew a preparatory drawing on a piece of paper. With the compass I drew the same design on the piece of bone.

Image Notes1. Preparatory drawing

Image Notes1. Transported drawing on the bone

Step 5: Etching #1With the conic Dremel bit (High speed cutter n. 118) I passed on the pencil lines to mark the drawing.

While on the back I took some of the sponge-like part off.

Image Notes1. Marked with the Dremel High Speed cutter n. 118

Image Notes1. Taking a little bit off

Step 6: Cutting #2Now that the drawing is firmly on the piece I cut the triangle away with the drill saw.

Image Notes1. Cutting as close as possible

Image Notes1. This tiny bit is holding it!

Step 7: Drilling #1With the smallest Dremel bit I drilled holes where the design supposed to have empy spots. Then using the Dremel Engraving Cutter n. 111 I enlarged the holes to theplanned shape.

Image Notes1. Giving the holes the desired shape

Step 8: ShapingThe sides of the triangle were then scraped to get the real shape. I used a combination of the Dremel bits that I have.

Step 9: Etching #2Then I etched the design on the piece with my Dremel bits.

Step 10: Drilling #2Holding the pendant with a clamp I Drilled a small hole on the side to pass a necklace into it.

Image Notes1. Holding firmly

Step 11: Done!I am very satisfied with the result that I got! The etching is good and visible even from a distance. The holes give it a touch of lightness that I really like. I am now lookifor a gold or silver necklace that can pass through that tiny hole on the side.

Image Notes1. Pendant and Ring

Image Notes1. On my girlfriend's neck.

Image Notes1. I like this picture because you can see the different thicknesses with thetransparency of the bone.
