Multipurpose Sharpening Jig for V-Bits, Drill Bits and Graver
Introduction: Multipurpose Sharpening Jig for V-Bits, Drill Bits and Graver
So this is one of those builds about which I was not sure whether it's going to happen or not. But like my every build this one also has a happy ending because by hook or crook I am finally able to make my own custom v- carve bits. So once the concept has been clear I thought it would be easy to make this but it wasn't and that is mainly because of the proper tool. The diamond grinding wheels I have been using are almost worn out and it really took a lot of time to grind down the stuff. It's not a huge deal for these wheels to do the final edge beveling which I mostly used for my knife but in this case, worn-out diamond wheels definitely increase the time. The overall conclusion came out from this band is that if you have the right tool for the right job then you definitely save a lot of time and this is only the first version of this project and I think with a bit of more time and pay some attention to design I think I can create a much perfect machine which can create precise v bits. I know some of you might feel that these are very cheap bits and why we need to build one when we already buy from china, but this process is to show how to make custom v carving bits which you can't able to find from anywhere else. The good thing about this system is that it's not limited to just one work, you can also use it to sharpen the drill bits and able to make your own custom gravers that suit best to your jewelry work. One suggestion is that if you have good quality tools then try to make those angles a bit more precise. I think a laser marking can do the perfect job in this case. So that's pretty much all about this build and if you have any suggestions feel free to post them in the comment section down below.

Step 1: ​Design and Inspiration
Designing is surely an important part of this build. You cant able to get the repeatability with hands, you need something in which you can able to hold the workpiece and able to shape it in whatever way you want to. The idea came from a jewelry video in which the maker uses these kinds of setup to sharpen the gravers. Onto further investigation, it brings me to grs website and I decided to use that method to make my own v carve bits. Since I didn't have a lathe machine so in that case, I decided to work with my trusty 3 in 1 CNC. I made a modal in fusion 360 and for the rotation, I decided to put the bearing in both the front and side plate. The second reason for putting the bearing is to avoid friction which will also going to reduce to worn out of the aluminum plate. Other than that precise marking can be made with laser and that will surely be going to increase the precision to a higher extent. One suggestion I wanted to give is to try to make the base a lot heavier. A magnetic base is also a lot more useful to lock down the jig to its place and for the vertical rod, a thick rod is much better that will give you a lot more sturdy. Definitely, in the future, I am going to make a much of a computerized machine to make these kinds of v bits, and maybe that not just remained to v bits only.
Step 2: ​Machining the Aluminium to Make Jig
So starting off this build is done from the bottom base. Since I didn't have a lathe so that's why I am doing this with my CNC but I think a lathe can make it in much higher precision. Being new to metal cutting on this machine I have no experience and as soon as I start the process due to higher rpm the flute got jammed and the machine skips the steps. Then off camera, I completed this job because I didn't start my camera to record this cutting. But the few things which I did might actually help you in your build. So if you are machining with aluminum try not to use 3 or 4 flute bits. I read some articles that 3 flute bit can machined aluminum with coolant but I struggle a lot because I am not using coolant during this work. But what I found is that a two-flute bit with 10-12k rpm with . 776
