Introduction: DIY Mosaic Pins for Knife Handles

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

Picture of 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

Picture of ​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

Picture of 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

Picture of ​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

Picture of ​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

Picture of ​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

Picture of ​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.

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

AMbros Custom (author)sztakacs2017-12-02

Thanks brother, I glad that you like it.

CarinH (author)2017-12-02

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. :)

AMbros Custom (author)CarinH2017-12-02

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.

Nice, easy and beautiful instructables..........voted

AMbros Custom (author)daabbu2017-11-30

Thanks brother...

itsmescotty (author)2017-11-28

Music way too loud in the video for me to hear/understand the author.

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

Brynleyj (author)2017-11-29

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

AMbros Custom (author)Brynleyj2017-11-29

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 :)

cavalier19 (author)2017-11-28

Neat Instructable. Plan to make some soon

AMbros Custom (author)cavalier192017-11-28

Thanks brother and good luck for your build......:)

kcoster1 (author)2017-11-28

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

AMbros Custom (author)kcoster12017-11-28

Thanks dear.....

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.

I do not buy the pins. I make them.

"The pin material is the easiest part of the project".

Brynleyj (author)2017-11-28

hi ,I love your idea ! I was looking at another instructable on here for filling holes with baking soda , glow powder or mascara for colour and superglue that sets instantly . ( I would imagine with no air pockets also ) I thought you may be able to play around with that idea .

AMbros Custom (author)Brynleyj2017-11-28

This idea works but its quite difficult to insert different size rods into a single pin or tube, I think that was a challenging task. I definitely tried to make a pin without any design by completely filled it with powder and super glue. Thanks........

CXYyuppie (author)2017-11-28

I've tried a few different ways before and they were ok but your technique seems to be the best I've heard of. Great tutorial. I guess I'll have to try again and report my results. Thanks

AMbros Custom (author)CXYyuppie2017-11-28

Thanks for your kind words. I also watched a couple of different methods but the problem was that I didn't find the proper size of apparatus which I neede for those process. Then I choose this method. One thing I also wanted to tell you that this method works on a resin which has very less viscosity. I also noticed that if you applied blow drier on your resin than you will find that it becomes less viscous than its previous stage because these types of things matter a lot. Off camera, I test some of my pins cut in half to check that whether its fully inserted in the pins in each corner or not but whatever I tested the end result is awesome. So be aware of the resin....... Goodluck for your build. Definitely, share with me once you have finished

seamster (author)2017-11-27

This is really cool! You really make some awesome stuff.

Keep up the great work!

AMbros Custom (author)seamster2017-11-27

Thank you so much I glad that you like my projects.

DEEJAY246 (author)2017-11-26

You got my vote in all 3 contests! This is great!!!

AMbros Custom (author)DEEJAY2462017-11-27

thanks dude..

deluges (author)2017-11-26

I really like mosaic pins. Good job on getting creative! Any pictures of a finished knife?

AMbros Custom (author)deluges2017-11-26

Thanks brother. The knife broke in half during quenching process and no longer usable, but working on another knife with same design and have some spine work too, definitely going to post once it finished and hope you like that too.

deluges (author)AMbros Custom2017-11-27

I'll keep an eye out!

jbrauer (author)2017-11-26

Nice write-up, your designs look better than the bullseye pins I made. You might consider cleaning your parts with solvent to keep the residual oil from the manufacturing process from blocking the epoxy bond. If you really want to go crazy, West Systems makes an aluminum etch kit.

AMbros Custom (author)jbrauer2017-11-26

Thank you sir, for the appreciation and thanks for the tip definitely take care of that in my future build.

graydog111 (author)2017-11-26

Great idea & instructable with lots of photos. I have made a few knives from things like a car leaf spring and a Sawzall blade.

I have also bought blanks (blades) on eBay & finished them. Anyone interested in knife making might try that first. They are nice & do not require many tools or cost very much. Scales (handles) are also available at very reasonable cost.

I really enjoy & get a lot of ideas from "Forged in Fire" on TV. Look at my Instructables on knives.

AMbros Custom (author)graydog1112017-11-26

Thank you sir for the information. I am also making my knife from leaf springs and I also inspired from Forged in fire. Those guys completely changed my mind and inspires alot. And more inspiration I got from people like you who never give up in their life, hats off to you sir.

ClenseYourPallet (author)2017-11-26

The only thing cooler than a handmade knife is a handmade knife with hand made pins. These are very cool. Voted

Thanks fellow, work on knife still pending but definately going to showcase the final result, hope you like that one too.

dave5201 (author)2017-11-26

You might want to rethink the very loud music in the video. It is very difficult to hear you over that.

AMbros Custom (author)dave52012017-11-26

So sorry for that, definitely pay attention towards this in future video, but what I say in the video is all about the material and the tools, hope that the build part in the video didn't dissapoint you.
