About to get my jig in few days so watching through all your vids. They are perfect and very informative, hopefully I'll be able to transfer the knowledge to my knifes. Thanks for these mate :)
Awesome to hear. Thank you and good luck!
Ive found those vertical slots are wide enough to fit some strong magnets into. Those magnets plus the standoffs keep my blades on the jig and lined up even with heavy pressure. Thanks for the videos!
Very cool idea I’ll give that a try!
Thanks for sharing your information. You’ve helped me get into making knives with your videos.
I use a tilt table and have found my lines get straighter with 60-120 belts. Also the faster the speed the finer the scratches look
Keep up the good work
Very good tip! Thanks for watching!
awesome Video. Thanks
Thanks for watching!!!
Thanks for sharing your grinding/jig techniques.
Thanks for watching!!
Thank you so much for details. Very helpful.
Awesome glad it helps!!! Thank you for watching!
Really appreciate your videos! I am just now learning how to use my jig and got some good insight from you. Using the vise grip, rather than running a screw through the blade and into the jig is a good tip. And then just placing your two set screws for when you flip the blade. Good stuff!
Glad to help! Thanks for watching!
Thank you!! Excellent well explained info!!!!
Thank you!
Alot of great tips. thanks for the video. I learned quite a bit . By the way I've just bought that jig. Love it
Awesome thanks for watching!
great video as always, thanks for making this video man!
Hey thank you for watching!!
I watched a knifemaker use a waterfall platen to do his plunges. Have you ever tried one of these? it sure did nice plunges for him with a smooth radius.
I never have but they are cool!
Fantastic video Matt. Been shopping around for jigs and this one seems pretty reasonable for what you get.
Thanks for watching!!
Those bolts sticking out and clamping it is going to be such a time saver.. Great tips! Speaking of tips... have any for using a jig and not burning the tip?
Slow speeds and fresh abrasives!
Like you said, this is not magic…there is still skill involved. To me it just helps you be a little more stable while grinding, especially for someone like me who has shaky hands!
Definitely true!
There's deffinatly a little to it, I don't have the bolts for knife to sit on so that's prolly why I struggle getting that same bevel both sides
That is definitely a big help!
I'll be adding them! Great videos
Can you go through your angle progression? Like I know you said you started with a 12* angle on the 36 grit belt, but what was your next angle? Etc. etc. etc.
I keep the angle the same for the full grind
Great job👍
Thank you!
Wonderful video! If I didn't know I wanted one before, I absolutely want one now! How do you cool off your blade while you are sanding? Are you dunking the front of the jig with the knife into water? Thank you for your information! 😁
I dunk the whole jig!
@@gentrycustomknives8008 I am sold! I am getting one! It will save my fingers, too! 😄 Thank you!
Put some baking soda in the water to prevent the blade from rusting.
Good tip
To your excellent tutorial I would only add the need for patience! The slower I go with my jig the less divots I get. One thing you didn't touch on was cooling the blade while grinding. Do you just dunk the whole thing, jig and all, in water? My solution has been to just do a few passes and then wait and think while the blade cools off, as I don't fancy dunking my jig into dirty water.
I did at the end of the video! 😉
Never miss your videos, always informative and helpful. Thank you.
Random question, do know if the KMG tooling arms will work in Housework Revolution?
Well thank you and yes I believe they are the same size!
That is a nice scandi. Not puukko. The bevel comes up over half blade ( often 2/3`s of the blade ) in puukko and seldom with ricasso. The upper part of the blade is straight or has a little bevel ( a half diamond - like ). And hidden or through tang. Normally , in Finland we forge the blade quite near the end measurements before we begin grinding. I understand, that the scandi knife and puukko often are mixt. I enjoy your videos , Juhani Lantta, Valkeala Finland
👍
The problem I keep running into with this jig is what you sort of mentioned at 11:20. It seems that no matter where I apply more or less pressure, my bevel is never perfectly even all the way down.
It definitely takes practice!
Beautiful knife, is that contrast as dark that type of Damascus steel will go?
No you can get it much darker
What angle did you use for the scandi grind ? You may have said but I’m watching this video in lunch just got my vevor jig in the mail yesterday and look forward to using it this weekend much love 🤘
It depends on your steel thickness! I think I did this around 10 degrees
Great video as always. I've made many knives from 1095 and just started using some 14c28n stainless. I pick the 14c28n as my equipment can handle the heat treat and tempering. The question I have is where did you source the Damascus SS and does it required a long soak time during heat treat. Thanks for the videos and keep up the good work.
That’s from jantz supply ! Standard soak time
So the OBM jig didn’t hold up? That surprises me given my experience with their products.
It’s workin great!
Great video, what's your recipe for the etching fluid?
Thank you
Hot muriatic acid for the damasteel
Super cool
👊👊👊
Can you elaborate on the Damascus Or do you buy the blanks made that way. Hope my question is not ignorant.
That is from damasteel
I didn’t see what degree you set the bevel
Great vidio
Thank you for watching!
Can I get damasteel hot enough to quench using mapp gas or propane?
I wouldn’t!
New maker here awesome videos. Without just running through material can you give me some pointers on belt speeds. Do I wana go fast at first with 36 grit and slow down as I go? Should I maintain the fast belt speed throughout? I’m sure different materials can change this as well. Just not many videos or information of 2x72 belt speed🤙🏼
Exactly! 36 grit full speed, 60 grit 70-80% 120 grit 60% is my norm
What is the steel call? Are you saying Dama steel?
Yes
Would you bevel before heat treatment or afterwards 🤔
I do mine after heat treat
Thanks for the great video! Once you have found your grinding angle on the first side, do you keep it to start grinding the second side?
Yes sometimes you have to tweak it slightly to make them both perfectly even
cool video matt ive had my OBM jig for 2 years and have never used it maybe i will try now may i ask what was the final angle you used ? and how about another build off like last year was fun thanks again Mark
I ended up at 10.5 . I’d like to do another build off sometime soon!
i use a simple aluminum angle for a jig and a couple small C clamps. The first side bevel always comes out good , but doing the opposite side bevel is always much more difficult. I think this is because the knife blade bevelled side does not actually lay flat against the jig, only the handle does so the blade actually bends or flexes slighlty when grinding the second side causing it not to be as accurate. I have to lighten up the pressure and somtimes even adjust the angle if the bevel is a taller one like a saber grind. I dont know of any way to make this easier to do. With a small bevel like you are doing this is not a problem because 2/3 of the blade is still held flat against the jig. If your bevel was a saber or full flat grind then the blade will not be flat against the jig. How can you get that second side bevel as good as the first side?
Fresh abrasives and not applying so much pressure to where the blade is flexing should fix that
Good morning from Naples Florida! I am also a Gander and live 6 months in the Summer at Higgins Lake. I Googled it many times and come up empty handed.
How do I determine the position of my knife blank in the jig? Do I try to position it as close to "level" as my eye will let me by looking over the blade (on the face side) then "eye ball it" so the reveal is the same all across the top of the jig or is it a different method? Thank you in advance for your help. Nubie on bevels.
That’s totally trial and error and how you want your plunge angle
whens the next vid gonna post? its been a while,.. hope ur well
Currently starting on my new shop! Might do some videos around that
This video made me look at the HT process for Damasteel, and no thanks! Don't want any liquid nitrogen hanging around with grandkids!
Such a cool steel though!
Send to heat treatment specialist
Do you temper before bevel grinding
Appreciate the video tutorial..sidenote layout fluid itself is a great rust prevention coating for everything including the belt grinder tool rest too..
The problem with Damascus steel blades is the compromised heat treatment between two dissimilar steels as the heat treatment can never be ideal for both steels..making for a decorative blade with inferior edge retention.. dissimilar steels have different ideal heat treatment requirements plain and simple.. same can be said about inferior decorative natural materials for handles vs synthetic materials..it seems most people prefer decorative wall hangers vs actual duty blades unfortunately..
Damasteel holds an incredible edge! Give it a try sometime!
I would think you heat treat according to the core steel plans?
Is a scandi grind good geometry for a knife used to field dress a deer?
No a taller grind is better for that
What bevel angle is a good starting point for the "steep" grind? what do you usually set it at (ballpark). Im just trying to find a starting point.. i have a similar bevel jig, but struggling to grind bevels.
I also see that the holes in your tang appear to be countersunk a bit.. whats the reason for that?
Around 12 degree’s depending on blade thickness and I’m not sure why I do that with the holes lol
Ok, *QUESTION.* Do you take commissions for clones of certain models made by other well known companies? [Under the table, of course.]
Absolutely not
Iam a beginner knife maker and bought the vevor jig what degree do you start your grinding 10 degrees??
10 is a good starting point!
How thin would you take s35vn before heat treat? .02 ?
I’d leave full thickness on s35
@gentrycustomknives8008 it's 3/16 thick.

Thank you
Awesome video, you the man Matt!
Thank you!!!
