In todays video I go over exactly how grind the bevels in a camp knife using an OBM bevel jig. Is takin a little practice to figure this out but I'm slowly getting the hang of it and share a few tips to my success.

Not too many in depth jig videos out there. Thank you for making this.
Thank you for checking it out!!!
Beveling is where I still struggle. Its definitely an art to learn.
Definitely takes some practice!
This format in how you did the video is really good for beginners. You’re explaining your thought process in every step and it’s extremely educational
Well I really appreciate your feedback!
😊

Thank you for this video. I just got a jig for my 2x72 and you explained everything very simply for me me to understand.
Glad to help!!
Thanks for sharing your insights and expertise. This is a well done video. 👍
Thank you for watching!
Mate I know this vid is 2 years old...but your stuff is very helpful....I hope you are going from strength to strength....because I have benefited from your content!
I really appreciate that!!!
Brilliant demonstration of how to use the jig. Thanks. Beautiful looking knife too. 👍
Thank you!!!
Very informative.. I learned a lot just by watching you and by listening to what you were teaching.. good stuff. Thank you for making this video
I really appreciate that! Thank you for watching
Great instructional video as usual.Some of your tips will be very helpful. Thankyou...keep up the Great work!!👊
Thanks for this! I've been using a jig for a while but now know I can improve my technique thanks to your video.
Glad to help!
Thank you. Much appreciation for taking me through this.
Glad I could help!!
Great video. You touched on all the problems I’ve had using a bevel jig.
Awesome to hear!! Thanks for watching!!
Really helpful ! Thank you. I'm going to grind my first blade so I think I can get it right with these tips.
Glad I could help! Good luck!
Thank you for this video, I have been looking into bevel jigs since I’m not any good freehand yet. I will be pulling the trigger on this jig. Keep up the good work you just got another subscriber.
Really appreciate that! It took some practice but I really like this jig now!
Great presentation! Answered several questions I had. Much appreciated.
Thank you for watching!
You did a good job on this jig answered a lot of questions. I’m just getting started making knives I made a bevel jig and you can still mess it up if you don’t take your time and make slow and lite passes. Thanks from Florida
Awesome to hear thank you for checking it out!
Great video! I just bought this jig and this video was very helpful!
Great to hear! The jig is fantastic compared to others I’ve checked out! Thanks for watching!
Very nice video, covered many of the things I have had trouble with. Yes jig grinding is not as easy as it looks. Well covered, Thanks
Thank you for watching!!
Thanks! Was looking for tips on using a jig! Very helpful. Subscribed!
Awesome! Glad I could help!
Great video, explanation and demos were on point, keep it up
Really appreciate that!! 👊👊
Great video. Best I've seen on how to setup and use a jig. Thank you
Thank you!
Thank you for this video, it is very helpful.
Great to hear, thank you for watching!
thanks for doing this video. really appreciate it.
Glad to help out!
I've seen a lot of videos on knife making and this is the best one I have seen regarding grinding bevels. Great work! Thank you for filming this, the instructions, and for posting this video! Is that the large bevel jig or the smaller one?
Wow well I really appreciate that! This is the smaller jig!
Thank you for this! I was just debating trying out a jig as i'm struggling so much with freehand. I can't afford to keep scrapping like one out of every two knives 😅 Just ordered this same one 🤞 I still plan on learning freehand, just slower I guess. I really want to achieve consistant quality bevels.
Glad the video helped you out!! The jig is great for consistency
Great job!
Thank you!
Nice.... What I have discovered is that when using any kind of jig is that the steel should be perfectky flat....i used to get steel which was a littke wa rped n that always messed with the results...maybe just me imagining things ....but it messed with the angle ...so morevadjusting n tweaking was always needed ....all the best
I recently bought a 3M Versaflo setup like Alec Steel…. It changed my life in the shop. It’s stupid that it costs $1600 because it should be a few hundred at best, but I highly recommend it for someone like you. Such a game changer. I forget I’m wearing it half the time and I can see sooooo much better. No more lines on my face and sore nose. You should check it out. Thanks for the bevel jig vid.
I have looked into those a few times and really want one! But that price tag 😬😬😬
Yeah it's a learning curve even if you design and build the jig yourself. 😮
I have this exact jig and this video was very helpful. Do you have any tips on how you adjust it for different sized knives?
Thanks so much. Been struggling with getting my bevels clean...about 2 inches from the plunge of course. Cant seem to fix it cleanly
This thing helps a ton!
Great video! One thing that caught my attention is you said you heat treated before beveling. Does that mean as long as cooling properly you don’t have to worry about it impacting hardness/tempering you’ve achieved? I’ve been hardening after beveling and this seems like final step I need to change.
Correct!! Keep it cool and ur good to go!
Excellent video. I do both jig and freehand. The knives I've been making must be freehand or a combination of jig and freehand. They are small ranch/Bowie style with a curved blade. I use the jig to set the bevel on the rear of the blade then freehand the curve. I do a hollow grind here. I've been using soapy water on the rest to ensure the jig moves smoothly. I never considered wax. Would most waxes work? Thanks
Very nice! I use a thin coat of pelican paste wax
Great video Matt! Just bought this jig. Are you keeping the same angle on the jig through the entire process?
Yes! Sometimes I’ll adjust it depending on how high I want the bevel
I'm new to making knives, but I'm having trouble with fitting my handles on the knife. So if you could do a video on setting knife handles that would be awesome. Thank you.
I have a few videos on that already 👊👍
Could you do one showing the difference between the large and small obm jigs? It would be great to actually see them side by side. Could one serve the purpose of both or is there too large a difference?
Great question! I haven’t used one of the larger jigs yet but I’ll look into it!
Great watch thankyou
Do you break the 90s on your blades prior to putting them into the jig 🤜🤛
I don’t. What’s the benefit of doing that?
@@gentrycustomknives8008 ive seen some do prior to putting in the jig
Hi, Amazing video with info. on bevel grinding with a jig.. Loved it. I especially liked the tip on the plunge line.. I am a beginner knife hobbyist & also wanted to know the right belt sanding machine that's reasonably priced.. Out here in India, we have brands like Ferm etc.
I want to be able to change to the various grits to get the finely crafted knife.. Cheers, Deepak
I’m not sure what is available in your country unfortunately
@@gentrycustomknives8008 No problem.. Could you instead share advice on the required features in a belt sander & also share Brand names of the ones available in USA.. There are some dealers who stock them..
I have the same jig to speed it up a little use a strong spring clamp to hold your blades it hasn’t Failed me yet Those Allen key hold downs are a pain in the ass I also use a spray bottle with water to cool No dunking that huge jig in a bucket of water very messy
Great too thank you!
You should do a video with the best / bang for your buck Amazon jig video
I’ll look into that!! I’m really impressed with this OBM jig so far, definitely recommend it!
So can you only use this with the size pin holes that the jig supports? I think it’s a 1/4” hole on the jig where the blade bolts down, but if you want to make smaller pins, how would this work?
You could always just use a vise grip or clamp to hold the blade to it
Thank you for the great tutorial!
One question, how much do you overhang the belt? I am struggeling with the right amount.
Depends on how you you your plunge to look. Start with even with the platten and see how it’s looking!
@@gentrycustomknives8008 That gives me a real harsh and sharp corner, I was looking for one more like you showed in the video!
Are you changing the angle while grinding? Do you get that bevel like that grinding at the same angle? What angle are you starting with and ending witg?
With that jig instead of using the bolts could you just use twist clamps to hold the blade it would be faster changing side ? Thanks
Absolutely! I might try that next time, however I do like the consistency from side to side of using the same holes.
What is the best way to sharpen and attach existing already made knives? I just bough the jig but having trouble attaching existing knives.
I don’t use this jig to sharpen knives
Do you ever change the angle on the jig while grinding in the bevel?
If it’s looking like the bevel is going to be to high or too low then yes!
I just got the same jig for Christmas. How do you decide what degree to angle the jig to? Also, are you rocking the jig out slightly when you get to the tip or does it just appear that way? Your videos are great and informative. Just enough explanation and talking. Thank you
I always start steeper then I think then adjust to where I want it once I’m getting the edge thickness close.
This video was very helpful. You said you were dipping it in water but I didn’t see that in the video, how often are you dipping it in water? Thanks!
When it’s too hot to touch give it a dunk
Wonderful vid...my issue is when grinding bevels...it seem that towards the tip of the blade I remove more of material and bevel line Is wider towards the handle and narrow at the tip...but at tip it's closer to the scribed center line...how do I correct this...I use a jig..
Try to shift the pressure down toward the spine once you are getting closer to the tip , that helped me a lot
@@gentrycustomknives8008 will do thankyou
OBM has two bevel jig sizes which one are you using? Thanks again
This is the regular size one
I might have missed it in the video, but how do you solve the issue of the belly thinning out while the tip stays thick? This is the issue that has always plagued me with sled style jigs and I cannot figure out if I am not angling just right at the belly and tip of the blade, or if it is an inevitable problem.
Looking forward to hearing your input on this.
It’s all about pressure and angle. Light pressure when going through the belly then angle in towards the tip a little with the jig.
@@gentrycustomknives8008 Thanks. I think I'll give it another shot today. I'm betting that having a good center line is also important so that you can keep an eye on the edge.
As soon as u have established the plung line don't stop moving the blade. If u stay in any one place while grinding it will be uneven.
Awesome info, thank you…….was this pre heat treat or post?
Post!
@@gentrycustomknives8008 thank you…..I realized that when you said the knife was ready for scales my bad.
You left your jig set at 8 degrees during the entire grind? Thank you! Appreciate the great videos.
Yes!
A quick way to interchange your work surface that I use is- I have the regular size work space on the tooling arm and then a larger piece of steel that I put magnets on the back of to quickly change to a larger work rest. The larger Steel work rest just affixes to the smaller work rest with the magnets. Works great for me.
Very good idea!
On my OBM jig, I’m having that issue you had at 9:00, but my bevel is much lower the last inch towards the tip, and I tried applying more pressure at the tip and less the rest of the way, and it’s still very uneven. I wish I could post a photo to show what I mean. Maybe I just over ground the rest of the bevel without evening the tip out as I went 🤷♂️?
That’s a very common problem. I try to put pressure down towards the spine as much as possible to avoid that.
So what angle do you use? And do you use 1 angle all the time untill final sharpening? Because 7 degrees sounds low compared to what I read? Or are you just switching to say 18 or degrees at the end?
Just depends on how high you want your bevels
I set up a stop on my work rest which gives a fail safe for the plunge
Man that’s a good idea!!
Good demo. Glad your wearing a dust mask. Aluminum oxide dust will mess up the lungs. More people could benefit from a dust collection system if they don’t use masks and/or respirators.
Common sense. Don't forget to wipe your ass!
.. this is important as well.
What degree did you set your jig? Great video by the way!
I’ve been messing with that a lot lately. Anywhere from 5-8 degrees
How thick did u leave the edge after the final 240 belt?
For the camp knife I take them quite thin, around .010
Thanks for the video!
Can you regrind an assembled knife using this kind of jig?
I’m not sure if you could do that
Did you quence and heat treat it first?
Yes
Do you have a method for determining what degree for bevel heights? Great video.subscribed
Trial and error! Lol
Basic trigonometry?
can you use these jigs on a 4x36 ginder?
I don’t see why not
Sorry its an old video, i noticed that your blade was not set against the the left lower stop on the first side, guess that caused the error you encountered. Great video really enjoyed it
I didn’t notice that!
Do you put bevels on after heat treating and finalize after tempering?
It’s all done after heat treat and temper
Just use a blue felt marker for layout.....cheap and readily available!
Doesn’t work as good as lay out fluid unfortunately
@@gentrycustomknives8008 I am sure , but it does work....
How does it perform on angled plunges?
I haven’t attempted that yet.
what degree set on jig for this type of bevel and how to choose angle for different bevel?
Trial and error depending on how high you want it, steel thickness, and edge thickness
Cut a allen wrench put it in a hand drill an back out screw out save time
Hello sir. How do you sharpen your knives?
I use the paper wheel system, I have a video on it 👍👍
if you had a longer work rest you could put a stop on it from side to side to keep you from going too far into the ricasso, just a thought...
Good thinking!
tbh i dont think the belly on the bevel looks terrible at all.. it just looks like thats how the knife is supposed to be
Well thank you!
Hey my biggest challenge with a jig is that I burn up my tips almost every time. I wish I could understand how you pull the jig away from the blade towards the tip and what pressure that entails as to not burn my tip too thin. I can’t believe you heat treat prior to grinding. I would ruin the heat treat on everything I touch if I did that. I must be using too much pressure. Thanks.
Sounds like you’re running the belt to fast or abrasives aren’t new enough
what are you doing for heat control?
Dunking in water when it gets hot
@@gentrycustomknives8008 I'd be tempted to try a water drip. I did that for my 10" grinding wheels and it works. The 72" belt would be somewhat different in how it slings water.
How do you determine what angle to use?
Trial and error basically. I start steeper then I slowly adjust it to get the bevel height where I want it
I hope this information is useful to some folks. I have a WEN 1 x 30 belt grinder and the regular size OBM jig. I noticed yesterday, when using the jig to put a bevel on a small pairing knife my blade is actually contacting the belt above the Platen. My solution will be stepping up to a 2 x 42 with a longer platen. 🍻
If your looking at getting a jig, get something comparable to the OBM, the cheaper imports are crap, trust me I know.
The obm jig is definitely the way to go!
Why do you grind the bevels after heat treat?
To avoid warping
@@gentrycustomknives8008 Hmmm, that's an interesting observation. I've never ground bevels after hardening...
Thanks for the video. There's not much good information on here surprisingly. I found a couple videos. But I'm beginning to think unless you have somebody in person that can mentor you then it's hard to really get into knife making. I've gotten to the point to where I can cut out the design and even draw them up. But when it comes to doing the bevels I'm completely styled out. Without a solid blueprint from step One all the way to the end step it's pretty much just tearing s*** up until several thousand dollars later we're still you might have figured something out on how to do it. So I guess that's what I'm going to have to do. It's simply too hard to go off somebody's video because so many people have different styles on how they do things and different tricks that they use. You know maybe someone with one of these CZcams channels should actually come up with that. Develop a course that someone can buy that shows you how to do everything from knife design all the way up to the point of finishing it.
I think that’s a fantastic idea! Nothing beats hands on training.
Is this already hardened?
Well I watched it again and heard that yes it is
Yes sir👊👍👍
I think my problem is keeping the jig straight. If you angle the jig it makes your bevel crooked
Why do you grind your knives after they have been hardened?
To try to avoid warping
I have the damndest time with jigs. On my little skimming knives jin works great 99% of the time on anything else. One side is beautiful and somehow the other side gets way off. I check the angle every time I flip the blade and mount it the exact same way as the other side. Drives me nuts. Literally just wasted 2 hours a couple belts and my last piece of thicker steel
You’re not alone. I still have all those same problems. Pretty frustrating really
@@gentrycustomknives8008 at least I’m not alone. Nearly cut my finger off on my bandsaw about an hour ago so i think I may call it a night for a few days at least until the finger stops bleeding
It's not identical though! Your first side the handle side is not resting on the stop screw and the other side is... Isn't this kind of the point of the stop screws?
Not sure what you mean
@@gentrycustomknives8008 if you look at when you did your first side with the 36 grit belt, your handle side of the knife is not resting on that bolt and the second side is, making your plunge line not mirrored.
wait, you didn't unplug your mask, is that how you probably use it ?
Those gigantic jigs are out of control. All you need is a small section of angle iron and some bolts with nuts to make a jig that's actually useable.
How are you supposed to dip that giant monstrosity in water to cool your blade while you grind?????😅😅😅😅
It’s nice to have accurate angle adjustments. Fits in the quench bucket no problem .
Whew he talks too much
Who’s he ?
@@gentrycustomknives8008 YOU if that was you that made this video 🤣🤣😂
@@Sarge2112 lol ok thanks for clarifying
