*addendum. Replacing the washers used in the video with nylon washers to pace your wheels is a better option. Others have also pointed out that replacing the bolt used to control tracking with a finer thread count would be better. Also, it's worth mentioning that the 2x72 parts market has expanded greatly in the time since I made that video and a lot of things like the platten and tracking mechanism that I fabricated myself can now be purchased pretty inexpensively
Have all the parts cut and ready to weld...using a treadmill motor with the speed control and it is also a 2.25 hp motor which will grind through anything. Had to watch the video about a hundred times to make sure I was doing it right😂. Thanks a lot man and this will be huge to my little knife making shop.
Always nice when someone has a build they walk you through that is actually practical and working. Many shops with setups never go int ospecifics or parts they just tell you where to buy or how much it cost. Hope this video gets a good consistent amount of views/likes
Easiest 2x72 build I’ve seen that doesn’t look all janky and cobbled together. Thanks
Yep and works properly. I got a free treadmill on marketplace that has almost all the parts i'll need.
Excellent Brother! I am at the point of needing a 2x72 to continue learning this craft and can't justify (or afford) buying a commercial one. This seems like just the ticket - a fairly easy and (much) cheaper DIY. I appreciate all of your videos, your devotion to verterans and for your service! I am a veteran myself (non combat) and lost a buddy (combat veteran) a couple of years ago to a PTSD related suicide. Your charity dagger build video hit me in the heart! Keep doing what you do!
William Freeman I’m still watching the video but the best price/quality I’ve seen so far is about 1600 😳 I bought it and it’s been built now but it hurt bad lol
"Dull wood chisel and a hammer" had me laugh out loud. Well done 👍👍
Thanks John, I need one but cannot justify the thousands cost! This walk through gives me the trial and error experience without needing to go through it! Sourcing the wheels will be the hardest part, I’ll get on to it pronto!
I love this design it’s simplistic but highly effective and doesn’t look to hard to build!
Thanks for the video; I now have a functional 2x72 grinder for less than a quarter of the cost of a commercial one!
One gripe, though--the exact setup used here will get a belt speed of about 2,300 feet per minute, which is less than half of what you need to utilize a good ceramic belt. HF sells a 3hp motor with twice the RPM of the one used in the video for only $10 more (just make sure you have 240v power in your shop).
To anyone using this exact setup: learn from my mistake, and don't waste good money on expensive ceramic belts. Stick to the zirconium belts--they're much cheaper.
The Vegvisir deserves this man a follow
Thank you for making this video! It's the most informative one on making a 2 x 72 belt grinder that I've come across. Great build. Now let's see him make something on it!
Built mine already and yes anyone Blacksmith anything should have one and I will say 1 HP is the minimum for power source., I'm not going to watch your video for I have mine , Seen your work before and before I build another I will watch this for I trust you to teach well,Sir thanks for helping me and the others who go to your teaching, Thanks
The best build I have seen,basic tools nothing fancy and explained in Lyman terms, Thanks guys.
@Old Hickory Forge really appreciate your channel and videos. Looking at getting started in blacksmithing. Your the first I've found to make it seem possible! Keep up the excellent work!
This is the best tutorial of a 2x72 I have found, thanks for doing this video. Good work!
Great design just finished up yesterday using your design works awesome and you can't beat the price over buying one . Thanks dude for the upload and the plans this thing will now get a serious workout!!!
Good to see a left handed grinder in the world! Thanks!
Thank you so much for the comprehensive video and not simply playing music and not saying a damn thing like all these other knuckleheads do. Extremely awesome dude! Thank you so much
Hands down best diy video. Makes it look easy
Thanks for this video! I appreciate all the little notable asides about the points of function in the design and tips to prevent potential hangups. Great video!
I swear every time I need to do a project the video I end up watching is from you.
MAN! This is what I was looking for! Thank, you, thank you, thank you!!! I have everything but the wheel kit, motor and D plate. I have all the hardware and steel. You have made my day. Blessings! You have my subscription!!!
Probably the best video I've seen on these. Well explained and didn't insist on building something stupid high end znd 220v right off the bat.
Great job on the build. All you need for the basics. Thank you.
Thanks John this will be a big help in building my 2x72.
Coffee's Forge I know!!! This is the best video on building a 2x72 I have ever seen! 👍
Just built my first grinder using your plans! Thanks!
Man ... You Rock!! This is the absolute best! Thanks so much for ALL the details. This is AWESOME!
Nice how you presented this. Easy to follow and simplified the build. Thanks
Awesome vid John, I found your channel about 5 days ago, and have been watching your vids, learned a few things that have helped in my blacksmithing journey, and after watching this, I think it might be time to upgrade from my 2x36 multitool....
Looks solid and relatively easy to build. Nice work.
Appreciate the DIY help
I enjoy your videos. Thank you for making these.
Wauw, super nice step-by-step how to! And the grinder looks good too.
Super nice step-by-step. Thanks !
great info, many thanks. best belt grinder video out there. practical design and lots of good details
Nice build. I just built one last week and i like how many different ways these things can be built.
Great video. clear and to the point. excellent work.
Great video! I starting to make my own 2 x 72. Very helpful. Ty
"Eat, sleep, hit stuff, repeat!" Love that shirt!❗
👍 before I watched the video because you put out quality workmanship.
Thanks again!
Awesome build. I've been looking for a video like this for a while. I seen other "DIY build 2x72 grinder" videos that the person used special computer programs, cnc machines, and metal lathes and they fabricate ALL of their parts except for the motor. I'm like well that didn't help one bit. But this video helped out a bunch. I'm going to start buying little by little and build one now.
That’s awesome John! I’m going to have to give this a shot sometime soon.
Nice vid and this is the first I've ever saw one built as a right side (looking at it) unit. Good looking machine too.
Its probably really heavy but light to him
thats what i thought lol
This was a great instructional and to the point! Thanks
Now that is totally doable! Thanks John
Really like this, love your toolmaking videos, helped me alot, thank you!
Nice build, compact. I wish I built mine that size..
Great video lots of detail, it helped me out a lot.
Excellent build! Thanks for going though this step by step! If I ever need another 2x72... I'll think of building one like this. It looks great! Hell can't hurt to have two 2x72s in a shop........ 😀 :)
400ish eh? Well I'm sure alot closer to that than a couple of Gs I've seen others set up for. It will grind. That's the main and most important thing. Thanks for sharing!!
Blessed days sirSir, Crawford out
Awesome dude great video thanks for explaining everything. Looking to build my own real soon.
Great video. Thank you.
Excellent video mate, thanks for sharing
Good basic easy to make grinder that will do most things people want, good stuff :)
Mine was tracking close to the tracking arm and I didn't realize it, I ground on a knife for maybe 20 mins then wanted to change belts, I put my hand on top of the post to depress the tension and found the metal to be smoking hot. Got a significant burn on my palm from that....... definitely check the tracking every time now. Great video
Awesome build brother
A few more and you will be in production. Looks good buddy 👌
Thank you so much! Tons of questions answered!
Great video! Thanks for all the information.
Damn good video very informative giving me confidence to tackle my own grinder build
Thank you so much for doing this.
This looks even simpler then the dcknives build. Hell yeah
Really Nice Job!
Awesome! Getting hit w/ hurricane Ida. Will save this and finish later. ThankQ.
"light enough to pick it up and move it", says the 6" 5" tall dude with 19" biceps 💪😛😁😎👍❤️
Thank you for this video!
I am going to make 2 of them just because.
Thanks for this video!! I want a 2x72 belt grinder and I have seen how expensive they are. I figured it wouldn’t be hard to build if there was a good video that described it. I have been making knives now for about a month and a half. Been using. 1x30 grinder and I got a 4x36 grinder, but I need to get a 2x72 grinder. I have posted a video, well several, of my first knife build. Juddie - J&J TOA
Great work
Sweet video man!
Thanks for sharing. That was a great video.
When you tap a hole, push the tap until there is tension, and then back off a turn. This breaks the chip. If you just keep trying to force it, you will risk snapping the tap.
Just pick it up and move it says the man big as a bull moose, great info thanks for sharing.
So! Great video!
At 5:35 or so,,When u attach wheels to platen! Use ONE NYLON WASHER ON EACH SIDE TO RIDE ON CENTER PORTION OF BEARING...HENCE ,TWO NYLON WASHERS....otherwisebig metal washer Will preventbearingfrom spring freely....GREAT VIDEO.
ALSO..GOOD IDEA TO PLACE THE INNER TUBE SEAM TO ONE SIDE...NEVER ON TOP OR BOTTOM,,IT WILL MESS WITH CENTERING
Hey! Camillus is right down the road from me! lol I live in Syracuse
Great video
i have watched several videos for this type of grinder, by far the best design for the home based build. Just watching the video made me want to make one...so i did. i have been fabricating for many years but believe a novice fabricator would be able to produce a good working grinder. Thanks
John, in building this sander, looking from the front. I’ve found that on the tracking mechanism if the pivot hole is drilled 1/8 off center to the right. The tracking has much more adjustment. It allows the piece to pivot beyond 90 degrees both ways. I hope this is understandable.
Thank you for all that info. Question
Could you have Installed a speed control on that motor??
Thanks again for all that info!!!
Good job
well done Sir
Got my steel 2day. It was nice 2 just turn on this vid. Make a list n got 2 the supplyr.
fantastic!
For under a hundred bucks extra you could turn your unit into a multispeed as well. I built mine out of scrap steel, used an old motor I scrounged, all up cost was for the wheels, around 125 bucks. The best bit though was the satisfaction of doing it myself for a 1/10 of the price of buying one.
I'M GONNA TRY TO BUILD THIS
nice job
I just plug my grinder into a heavy duty power bar and the power bar is my power switch.
Super także sam sobie taką maszynkę wykonam 👊🏻😁
Great video. I'm going to follow this for my first build. I already have some scrap metal to start with, but my square tubing is 1.5" and 1". Do you think this will be a problem or will this work? Also, will a 3600 rpm motor work on this?
Just built an exact replica of this, besides fabricating my own wheel kit!
Very nice
Thankyou👍
Thanks for this video! i've got my materials on the way, do you have a blueprint PDF stashed away anywhere? or should i just wing it off your drawing, real excited to get started on it
you could have uploaded the parts list, would have been easier. Great video.
Why is it blacksmiths have the same idea the same week. I’m fairly sure we don’t discuss it but it happens a lot. You and Tim did grinder videos, I’ve seen it happen several times with several channels.. must be like a subliminal wave link or somthing. :). Nice video
Ouroboros Armory to be fair this video has been planned for several weeks
Old Hickory Forge oh I bet, I film mine sometimes months before I release them. I don’t think either of you realized the other was doing it. I bet both of you filmed it a bit before today, and released it not knowing. That’s why I find it funny because you and Tim wasn’t the first pair that it happened to. I just find it funny :)
Yup I'd noticed that too. It's kinda like things go in waves...thru the waves lol. As in this case two creators put out videos on a higher tech subject within hours of one another. Just too much has to go into these videos to be intentional lol lol.
Can you give us the length of the 1 1/2" platen arm piece that inserts into the frame?
Great build. Need one and this is the best build I have seen for someone that doesn't have a full on machine shop in their garage. Quick question..is there a way to add an arm for work table etc.
i threaded a hole opisite the d plate to bolt a tool rest on and the angle can be adjusted, also bolted the table to the support arm with adjustment in and out for prober belt clearance.
Can you use 1/8 thick tubing instead?
Has anyone asked about putting a speed control dial on it and would that work in place of a vfd? Awsome video I'm in the middle of building one but I think I'm going to change my plan and use some of your ideas
If you want speed control you really do have to run a VFD with a 220v circuit. Wiring a speed control to a 110v motor is really hard on them and will significantly shorten the life of the motor.
