DIY Mosaic Pins for Knife Handles




Introduction: DIY Mosaic Pins for Knife Handles

About: Hi, I am crazy about creating things with my crazy mind. I love making unique things that can entertain and educate you. I love Instructables because it's a Great source of inspiration.

Hello and a warm welcome to all Instructables community. In this instructable, I am going to show you a simple and easy to make project. If you are a knife maker, then I bet you definitely like this. If you are making knives and install mosaic pins in their handles than definitely this project will save you a lot of money. Generally, If you are going to purchase these pins from the market you spend around 5-10 $ on a single 50 mm Long pins. I made a bunch of 100 mm long pins around 17 $.

If you like this instructable then definitely tells your opinion, because they are more valuable. If you didn’t get anything then toss me a message in the comment section. I always feel happy to help you guys.

Step 1: Material Required

Although you are free to choose whatever size you need, generally in knives pins from 6-10 mm are used to fasten the handle with a knife. The more variety of material you get the better design you are able to make. I buy whatever I got and used in this build. Following are the material I used in this build.

1. 10 mm brass tube.

2. 10 mm stainless steel tube.

3. 8 mm copper tube.

4. 6 mm brass tube.

5. 3 mm thick aluminum wire.

6. 1.2 mm brazing rod.

7. Two-part epoxy resin.

8. Colour pigment.

Step 2: ​Tools Needed

Since this is fairly simple build and there doesn’t need a bunch of tools. I completed this whole build with simple hand tools. Following the tools needed to build these pins.

1. Pipe cutter.

2. Wire cutter.

3. Hand hexa.

4. Hot air blower. (optional)

5. Drill machine and bits. (optional)

6. Syringe.

7. Files

8. Sandpaper.

9. Super glue

10. Masking tape.

Step 3: Material Cutting

Since there weren’t tons of cutting involved in this build you can cut all the material with simple hand tools. The overall length of the pins I kept is approximate 4”. The brass and the copper tube are cut with the help of pipe cutter and the stainless steel pipe is cut down to length with the help of hexa. After that, I close one end of the copper pipe with tape and insert the brazing rod in it and cut down to the required length. The tape serves as stopper and every cut is of the same length. Then I cut 3 mm aluminum rod to required length. Some length I kept slightly longer because I want to do some experiment.

Step 4: ​Making Patterns

After that, I lay the pieces onto the table and insert them into the bigger tube and make some random pattern. This work is completely depend upon your imagination and variety of material you have. After that, some designs are difficult to keep them in its position that’s why I glued them with super glue So that they remain in its position during the filling process.

Step 5: ​Stand for Pins

After the pins are prepared I made a stand so that pins can stand at the vertical position. For that, I took a scrap Piece of ply and mark hole location by providing some gap. Then I drilled 10 mm holes so that the pins can be easily inserted in the holes but the hole will be drilled to a shallow depth. Then I close the one end of the pins and insert them into the holes I drilled.

Step 6: ​Mixing Resin

Then I mixed two-part epoxy resin and add some glow in dark pigment. You can add any color pigment you want but always make sure that pins and color are visible very clearly. Because this thing creates a nice contrast in your pins. Then with the help of heat gun remove the bubbles from the resin and complete the preparation.

Step 7: ​Filling the Resin

Then with the help of syringe, I filled the pins completely from top to bottom and to make sure that no air bubble left inside the tube I constantly heat up the pins at regular interval and also do little bit of taping so that resin would be able to fill up in every empty space inside the pins. Then I allow it to cure for the whole night.

Step 8: ​Finishing the Pins

Then I removed the pins from the stand I made and prepare them for finishing. After removing from the stand I Filled down the ends with the help of file and finish the filling marks I sanded them up to 220 grit of sandpaper. There doesn’t need too much finishing because rest of the sanding is done when these are installed in knife handles.

Step 9: ​Finally

The end result of the pins is in front of you. If you like this project then don’t forget to give your opinion. Thanks for paying attention.

    thanks for the info i am just starting to try and make the knives, will upload when i have something to show. Cheers dave Ware

    No, they are not press fit. The hole drilled in the handles barely larger than the pin, might be fraction of mm (The pin diameter is 9.90 and drill is 10mm) If they are press fit then there is a tendency to break or chip out the scale of knife and with that little gap the epoxy hold everything tightly together. Might be press fit technique works better in metal scale but in my build I always drill 10 mm holes for my 9.90 mm thick mosaic pins. Thanks:)

    I think I’ll try your technique with larger pipe for guitar volume and tone knobs. The glow in the dark pigment is a great idea.

    I think I can adapt this to some other projects I have in the works. Thanks for a great idea.

    I love this idea. Been wanting to make (or at least assemble) my own knives for ages. This is a great way to make them even more unique!

    Great project, but the video needs some work. I had to turn the sound off because the music was way too loud over your voice. Also the low contrast of the captions (grey on teal) makes them nearly unreadable. Go with a dark color and a light color together instead. :)

    Thanks for the compliment brother and thanks for the suggestion about the video. Definitely paying more attention towards this in my future build videos. Hope nobody complaint again about the video work :) Thanks for give your time.

    Sorry, for that brother. Definitely pay attention in future builds

    Hi it was just an idea , I have no experience at this sort of thing , all I know comes from watching forged in fire :) I like your idea of getting a knife blank from eBay to try it out ,I've seen a nice Damascus one. Oh dear I think another addiction might be starting . I will be giving you my vote for your instructables

    Thanks my dear, I also got addicted from Forged in fire, currently working on my first coal forge and thinking of making my own Damascus rather than buying it. I think that will teach me a lot :)

    dam, those are some sexy sticks. Have to remember this one

    I've made pins like this for fret marker dots on guitars.

    The pin material is the easiest part of the project, but for oohs & aahs the pins are the most bang for your buck (and time).

    Yeah I agree with your words at some extent but if someone using these pins a lot, than I think it's a wise move to make bunch of these for own rather then to buy them, which definitely saves a lot of money. Time is not a big deal if you use a resin which cures with in 2-3 hrs there is no big issue in time as well.
