Knife Making - NEW Way to Grind Bevels?
HTML-код
- Опубликовано: 17 ноя 2024
- Here's a new way (I think) to grind knife bevels. I wanted to see if I could combine two techniques: the file jig method and the angle jig/belt sander method. I am no professional knife maker by any stretch of the imagination... just a guy always looking for more efficient ways of doing things.
Please leave a comment below if you seen this technique before or have suggestions on how I can improve upon it. Thanks for watching!
That is ingenious. With some tweaking I'd love to see this work to perfection. Well done!
Hey thanks! Yeah I have a few ideas I think will make the process better…
O my God that's a new trend ....you made my day.... SIR 🙏❤
You obviously have your hands growing out of the appropriate place so I would recommend investing the same money and time into just learning to grind on the grinder. Realistically, you will have more success faster. Most people really get a hang of it. of course innovation is fun too.
Very clever idea! I'll be interested to see how it shapes up (no pun intended).
Subscribed because there always has to be madness mixed in with genius ! lol
I applaud your creativity.
Brilliant!!!
good idea. Looks promising.
Friggin brilliant! If you dial this in, you could really have something!! Also, if you could somehow turn the blade around, you may be able to do a hollow grind.
The reason that there's an issue out toward the tip is because the tip curves upward, toward the grinder support post. As the grinder rides along that upturned end, the angle of the grind is increasing, so the top edge will indeed move downward. Said another way, if the grind angle is set to, say, 20 degrees along the straight portion of the blade, it's more like 18 degrees at the upturned tip. The grind angle is steeper, so is shorter, just as you're seeing.
This has my imagination on fire! I’m always thinking of better ways to do bevels, and I really like where this is going! I might have to play around with this concept in my shop! Great stuff, subscribed and hoping to see where you take this
Great idea 👍❤
I’m a hobbyist knife maker. I don’t have a machine shop. I bought a pvc 1x4 and cut it into 8 pieces. I cut each piece at an angle on my table saw starting at 24 degrees and going down in 3 degree increments. I bar clamp my blade blank to the desired edge bevel and grind it. Very simple but it works and I can see the edge as I’m grinding.
I would be interested to see how that works. Can you share a photo?
@ I could if I knew how. 😀
@ looking further into it and i dont think you can on this post. You would have to on your own channel. Or on Facebook. Thanks though.
@ Basically think of a 3d rectangle 10” x 4” x 1”. Lay it flat lengthwise so the 1” is the height. Set the table saw blade to the angle you wish to grind your bevel, for example, 15 degrees. Rip the piece. Now stand it up on the angled edge. Clamp your blade to it and you are ready to grind it at 15 degrees. It works, it’s just not something a machinist would make.
@@ozarked2363 thank you. I had it all but how you clamp a blade to a pipe. I will give this a try.
You could replace the wobbly eye bolt with a "Spherical plain bearing" for more precision
You have my attention... Come on Nikola, pave your way 🤔
That is crazy I thought I was the only one that thought to make a grinder like this. 😮
Yeah man, not sure if it would work but I think I could be great with a little more tweaking…
Love it....
That was cool
You could also use a mirror on the 2x72 to see what you're doing if you want to got the belt grinder route. It's something I picked up while watching pottery videos
Great idea! Thanks
Good thinking!
Trabalho excepcional! Deus te abençoe!! 🙏🏻
Not nearly as ridiculous as expected! Better visibility & ergonomics, but abrasive costs probably higher + maintenance
Yeah man, it was a silly thought I just couldn’t get out of my head…. So I thought I’d put some effort into the idea. Works ok but needs a few tweaks.
i always thought that those hand held belt grinders made sense. You need a file guide for the plunge line
Thanks for the advice!
Handle placement is too high relative to the grinding surface, if the top of the handle was actually below the relative grinding surface I believe it would be easier to guide. Hope this tip yields better tool control. I need to modify the sharpener I purchased ASAP, it has the same issue.
Thanks! I’ll try that.
If you have time and are willing to share how did you build that bevel grinder?
I used the same principle for the manual file jig setup, but instead of using a file, I welded a flat piece is steel to a rod and connected it to the grinder. Hope that makes sense..
Hi i like your solution very much. i would love to see more videos using it. Because of my back pain, standing at the grinder takes the joy out of knifemaking for me. What you have come up with looks like a solution to my problems. How long did it take you to make this bevel? Best regards to you from Poland.
I am actually is the process of buying a two inch sander because I think it will work even better. I can say this about how long it took: it was way quicker than the file method but a bit longer than the 2x72 belt sander. Hope that helps😁.
I forge all my bevels in. Way less grinding and belts are expensive.
Forge On!!!
Have you tried running a bevel on a milling machine yet. The tool up sucks but the results are nice
Not yet. Any advice?
Yes a belt grinder a whole new way of grinding bevels..
plunge line jig made from files
Come back and clean it up with the file.😊
This is the answer really. Rough in both bevels then refine everything with the file.

You just need to make a new jig for your 2x72 out of a piece of angle iron. Then you can easily see what you a grinding.
And this is the last video?
So far. Been working on the latest version of this idea but not ready to do video just yet…
Go freehand, problem solved.
Grind like this takes me about 5 minutes per side to establish, and maybe another 5 to finish.
There is no other way that is faster in handmaking a knife than a freehand grinding.
This is brilliant, I plan to try this on my next knife.
Red beard ops has a video you may have seen where you first set your plunge lines and then grind which I think would pair well with this method. Did you start at a higher angle and work your way down as is normally suggested with the file method or calculate your angle and set it from start to finish? ruclips.net/video/oGhAdcNafhA/видео.html
New subscriber thanks for the idea!
Hey thanks man! Yeah, I started at a high angle and worked my way down. The sander has an adjustment to set the angle so I didn’t even need to move the eye screw. Yeah man, I love Red Beard!
Really nice that you don’t have to move the eye screw. Do you have theories on how the feathering and or bevel droop happened? Without doing it myself I can’t conceptualize how either would happen, seems fool proof to me. Also have you tried the setup for sharpening?
Sorry for the delayed response. I think the feathering happened because I got a little shy while grinding toward the tip and didn't apply even pressure while moving the belt sander out over the tip. I believe the bevel droop could be corrected by going over it a few more times and just applying more pressure in the middle area. I haven't tried this setup for sharpening but I'm sure it would work just fine. I have used it to polish and it works great. I am int he process of buying a Makita 9031 1-1/8" x 21" Belt Sander which I think will be more sturdy and effective. I'll make a new video once I get it all worked out...@@andrewday5152
🤣👍🏻💪🏻👊🏻✌🏻❤️🇩🇪
That jig for your 2x72 is just poorly designed. Walter Sorrels shows on his channel how to make a fine jig out of angle iron.
Your new method has no provision for cooling the metal.😅
