- This video is my 2x72 belt grinder build from an old workout bench, scrap, and a treadmill motor and parts. I tried to make this as portable and adjustable as I could. Also the treadmill motor and motor control board make it variable speed without changing a belt on pulleys. How to build a 2"x 72" belt grinder.

using the treadmill motor was ingenious for a solid low budget build, one can find treadmills almost nothing when people gives up on the work-out-at-home intentions.
Excellent build, best one I've seen on youtube.
i dont always build a belt grinder but when i do build a belt grinder i watch the dangerously wise manmademike and yes i stayed at a holiday inn express the night before ..
So many people are way smarter and more creative than I am. Great work!! Thumbs up!
Mike:
The repurposing of readily available items is both economical and thoughtful. Please continue with that approach. Excellent work.
If a mech. engineer and a field machinist had a baby he'd be you. Wow is all I can say, great job.
I'm blown away how great that turned out, especially with basic hand tools. Thanks for sharing and all the time spent editing to make this exciting to watch. Joel.....
Thanks for acknowledging the editing. There are errors here and there, but I am glad you appreciate the project as a whole.
What one can do with good power tools! Great build too! Regarding belt wobble, I noticed long ago that leaving my belts on the grinder contributes greatly to this "wobble". The tracking wheel puts a slight kink into the belt if left on the grinder. I take mine off at the end of the day and can honestly say this eliminated the problem.
I accidently stumbled into your video and I was just blown away with how you managed to build a 2x72 out of repurposed materials. I truly enjoyed this video ... you have skills and then some!! Cheers
I'm surprised there isn't more people getting upset at how you're using the angle grinder. Wouldn't do it myself but it works for you and you're still in one piece!
Welding the pipe on the fry wheel.. you sir gee gave me $ million idea ...thank you so very much SIR GEE
I did a half wolf whistle when I saw the sharpened edge on that blade. Nice job, brother.
Cheapest no bullshit design and build on TH-cam, definitely gonna be using this, good shit.
I'm really glad I didn't throw away my little old belt sander, hehe. Nice build! Thanks for the video!
I think I've watched most of the 2x72 grinder builds on youtube. I'm way over doing the research and planning phase of building one for myself. This one is one of the better ones in my opinion. Good work.
I appreciate it TY. I tried to be different by design and using items that would've been thrown away.

@@mikemanmade3087 are you on Facebook? I’d really like to dm with you a little bit about this build. Is there a way I can message you or email you? Thanks man.
Nice to see a grinder built without using a lathe at some point. Obviously if someone had access to one use it, but I don't and most of the ones I see built get a few fancy parts turned. The band saws are super handy but a guy with who is careful with a grinder and drill could do all of this.
Excellent build. I really support anyone building from scrap. Much better than seeing this material in a landfill.
Thanks for the vid. I can see why a belt sander is what you chose to build. Well done.
Very nice. That router trick was genius!
Using the router to make the 'trunion' is a fantastic idea. Keep 'em coming.
MKRBRKR I've got to second that.
MKRBRKR Any idea what kind of bit he used ?
Not sure, but a 2 flute wood cutting bit does the trick. Lube with wd-40 or Tap Magic.
Didn't know those could be used on aluminium cool well thanks :)
Probably a milling bit. But that was a brilliant idea i would never thought to use a router.
That Workout Bench, really worked out well.
Hell, who needs a Bridgeport? Run what you brung, I love it.
The design & execution are excellent. Having ZERO narration, nothing to explain what "this little bit here" is for... that knocked a couple points off for me.
Whoa, whoa, whoa! Using an old weights bench as material? That's, well, GENIUS! Why the hell didn't I think of that?!?! They're cheap as heck and perfect!You, sir, are officially my belt sander hero :D
Wow, that thing must way a ton, it's BUILT! Great job, it's a nice project.
Most well designed 2x72 on TH-cam! Great build very robust.
Using a router to make that cut! Are you kidding me! I would have never thought of that. Well done man!
Super nice custom built belt sander. When I come across a treadmill, using your design. Thanks
Thanks for sharing your this machine.i might try to copy this if you don't object. Very well done and thanks again.
For sure the mother of invention, I like your "Milling Technic"; to make that slot! Nice job!!
Looks good. I have built a grinder once as well. After some research I found the belts are supposed to run around 3600 ft per min. So to slow down my 7000 rpm treadmill motor and keep the power up I installed a jack shaft the motor turns and reduces the speed in half and then turned a 4 inch drive wheel from wood to run the belt. it works great tons of power you can't slow it down while grinding. I think my motor was 2.5 hp. Other than the belt speed it looks like you have a real solid design. I only commented because you stated it was a little fast.
I've never seen so much flex in a Drill press table before! amazing it drills holes at all as bad as it bends and springs back!
Saw that. Was wondering if there wre pilot holes drilled first - they tend to reduce the axial load.
I found this magnet in the shape of an arrow sandwiched between two pieces of sheet metal..when digging in my Garden last year.it looks to be very old maybe the 50s..its in pretty bad shape..corroded sheet metal..its been sitting in front of me this whole time..hoping it would just snap in my brain what it is...during the second watch of your video..i noticed your using a Magnet in the shape of a arrow sandwiched between two sheets of metal..So not only have i gotten some very great ideas about building my 2x72 and also now now what this hunk of rusty magnet is used for..i am going to clean it up and paint it red like it was and i will use it building my Belt grinder..thank you for solving this year old mystery
Did I hear jump around in the backround? ... thats friggin awesome
Me when he fastened the handheld belt grinder to the vice: "well, that doesn't seem like the safest way to... Oh! I guess that's why he's making a fricking belt grinder!" My head sometimes 😂
Uses a tiny hand held belt sander to make a powerful 2x72 haha great work
I've never seen anyone file as fast as you do! Lightning speed lol! Great work and thank you for all the great tips.
Great build and nice job on a professional looking g DIY machine. Just because it's homemade doesn't mean it has to look rough.
Man this video blew my mind. I've just gotten into knife making and other odd metal oddities and have to say your video blew my mind couple hundred bucks and boom art.
fantastic job! I have been looking for a treadmill. . there is actually a free treadmill section in the local Craigslist. . issue is getting to one before it disappears as they put them on the street and junk collections snap them up.. soon I will have one and I will be watching this over and over again for ideas and basic direction ..
Good luck!
I like this grinder. So many ways to apply in woodworking. I will attempt to do the backbone of mine out of wood instead of aluminum. I'll use wood due to the fact that I do not have all the cool tools you have in making one, and wood should be efficient since I will be working with wood. Your welding skills are pretty solid, and again... this is the best belt sander I've seen.
Thank you for sharing, and if I get around to doing mine... I'll send you pictures.
Peace!
Great job, I like it. I happen to have an unused freebie bench and treadmill. Guess what. Thanks for the great tutorial,
Great build. I've got some stuff lying around that I could convert using my powertig. What a great idea.

Love the recycle and re-purpose instead of the thrash and trash mentality. Thanks.
Fantastic job. Loved the router trick to slot yr aluminum. Very good build!
Very nice work, especially loved how you routed the curved slot. Other men would need $5000 in machinery for that.
As for your belt wobbling issues, it could be because you crowned all the pulleys. This can create instabilities as oscillations build up. It's a complex mathematical/control loop problem I don't fully understand, but from practice it is often best to have only one crowned pulley, usually the driving one. I think Matthias Wandel did some work on this if I am not mistaken.
I am pretty sure you are correct! I noticed the consistent movement in the belt and that was my first thought,the wheels.
I love this build by the way, not everyone out there that could use a belt grinder can afford even the parts and materials to build one but by going this route it makes it attainable for most everyone (including me 😀)
So thanks for sharing this !!!!
Best use for a treadmill EVER!! LOL Excellent all around knowledge of tools/tooling and craftsmanship! You must be an electrician :)
Oh great!
You have golden hands!
Thank you so much!
This was a great build to watch. You absolutely killed it. Improved me to get in the shop myself. Thank you!!
Motivated*
The final assembly looks fantastic painted up. First class build.
As much as I hate painting, it really does finish the project. Thanks for watching.
Completely enjoyed the video. Your east coast cockiness came blasting through in your statement that "it works great cause I built it". Hilarious. One note on future builds: resist the temptation to use bolt threads as roller spindles. You'll find that the wear factor, especially at higher rpm speeds that you find on belt sanders, will cause fast quick uneven wear and a quick end to your "perfect" belt tracking. Also, kudos on crowning your UHMW or Delrin rollers (not sure what they're made of). Great job.
Great job. I built one out of wood last year and it works fine for what I need but I want to build one out of metal. I enjoyed watching, it was very informative. When you started cutting a hole with your router, I could not imagine what you were doing and then you started moving in a half circle, I would not have thought of doing it that way, very smart . Take care.
Excellent work! I like that you used material you had! I never throw away metal your a good man and thank you.
That looks absolutely savage and I love it. I might even make one with my everlast welder from my own old workout bench.
My only problem with your videos is . . . I'm supposed to be getting some work done! I start watching your videos and get hooked! Keep up the good work.
Thanks Jerry. Don't let work get in the way of your viewing of my videos. Remember priorities.
Lol I have the same issue start working and watching his videos then I realize that 1-2 hours has passed and I got jack shit done :)
nice hand work, good file job too. might i suggest a file card. it cleans your file to keep a good cut. with metals that tend to cake it works like a charm.
You must have missed the part when I use one. Thanks for watching.
Awesome project! And thank you for teaching me how to sharpen lawnmowerblades :D
I saw this sander in person yesterday, its nice, good job mike, and thx for the cub, dad is lovin it.
The video you made is very good, the introduction is very clear, you are very skilled, thank you, let's exchange for a long time, ,,,
That's a tool to last a lifetime,..👍🇬🇧...."this thing tracks perfect,I know that cause I built it"...🛠 !..that got a sub.
Nice job and very inspiring!
But you should really fixate the adjustable drilling table while drilling. I have seen several of these been broken around the Column because they had too much play! Keep them vids coming!👍👍
One man's scrap, is another man's treasure
Router as a milling machine? Brilliant!
Best use of gym equipment I´ve seen so far!
Very nice job.. But please.. Get a guard on that grinder. We are many people who want to see more builds from you. :)
Dude u did so much with so little...hats off to you!
hi, you are like me using useless stuff to make into something useful, the treadmill motors out of large treadmills are apparently very good motors as variable drive, good job, you earned my Bull Terror Award.
Is there a trophy? I hope so.
Nicely done, slick editing. Have fun and thanks for taking the time.
all that is needed is to add a disk on motor to make it a dual sander great build
One of the best "how to" videos I have ever seen. Excellent work all round and some really good ideas. Suggest that you fit good gaskets to the electronic box door and the potentiometer box. Apparently the grinding dust quickly destroys the electronics. Keep up the good work.
Hey thanks! I humbly disagree though, there are so many great makers with so many great videos. I'm just tagging along.
nice mig welds. It great to see a nice bead on dyi projects
You could turn that 20$ into a huge profit. I'm new to knife making. I bought a cheap harbor freight 1×30. As I get better I'm definitely going to need more power. Anyways you did a great job brother1
Pissed that you can't, seemingly, buy the componentry for this build. I'm not against making your own stuff but it can often end up more expensive to buy the metal, fasteners and fixings.
Super handy workshop addition.
Man that chop saw can cut some thick metal!! 😲
Really impressive design and metal smithing!
I’m going to have to simplify it a little. Your skill level is far better than mine
wow' I've been keeping a workout bench for a while for this exact thing. Cool I'm glad someone has tackled this.
Great work! i caught that "F##K" when you ran out of shielding gas.
i was wondering why he started stick welding part way through. I did see the weld where he ran out of gas too now what i think of it haha.
Congratulations stayed perfect, here in Brazil we do not have as much facility with tools, because it is expensive, but your ideas are great.God bless ...
Lovely build . Mike, from your comments below , reference wheels . Try to look for pallet truck wheels . They are approx 4" wide and come with a bearing already fitted . Good heavy duty bearings and hard wearing surface material . Looking for some more of your vids now .
So it seems like you have knocked it outta da park! Enjoyed your tricks, craftsmanship and forethought.... Great Job
Next?
best use of a home gym I've ever seen.
Brilliant repurpose of the bench and treadmill.
WOW! THAT'S AN AWESOME MACHINE AND INCREDIBLY IMAGINATIVE!
Thanks Mike. Wait, are you me? Because I think the same way.
Very nice. Just picked up treadmill for $50 off craigslist with 5075 RPM 1.75HP motor. Stripped it all down yesterday. I was contemplating how to drive the belt. Looks like you just welded tubing to the flywheel. I might do that, or I may use the belt drive from the treadmill. That will slow it down to a more reasonable RPM. Originally I thought I would use a 3ph motor and VFD, but that gets pretty expensive. The one concern I have with the treadmill motor is keeping the dust out. I'll likely make an enclosure for it. I will take your advice and make the wheels wider than the belt. I guess 2.25 ~ 2.5 should do it. 2.5 would let me run wider belts as well, if needed. I am also a new subscriber because of this video! Andy
great video great machine, you say the motor will run at 6700 rpm it looks like you have a 80 mm drive wheel this will give you about 28 meters per second belt speed, pretty good but most manufacturers suggest up to 32 meters per second for steels this would require a larger contact wheel, easy to do, your first test on the machine the belt was running slower than in the second part of the test ,this time it was a lot faster, this does generate heat and a bucket of water is handy, or you can use damp running with a water mist, to cool the part , keep up the good work
Great build! I love building re purposed stuff. Put a a treadmill motor in my lathe about 2 months ago and love it.
TY. I was thinking about putting one on my lathe too. How did it work out?
mikemanmade it's working really good so far. You can check out my video on it at "Jake of all trades ". I've made a few pens and tried making a bowl so far it seems powerful enough for the size lathe I have
Excellent job, haven't seen one this fine detailed before. well done,
Absolutely brilliant. Good craftsmanship.
Get that man a Binford Tools t-shirt!
I build stuff at your level . . . .and you make me happy
Forgot to say, very nice build...
I like your attention to detail. May I make a suggestion? Music would be better than the fast forward sound. I am going to try and make this.
You have some really smart ways of doing things
Wow! talk about repurposing ... I want to go green like this too... great build and thanks for sharing.
you got me with this. some weeks ago I also cutted my workout bench to get material for a belt grinder.
awesome video & techiques. thanks for uploading
Cool, thanks! I like your hat.
WOW Beautiful JOB...I learned a lot !! Thanks sooo much....Re- Purposing is the way to GO !!
May I suggest a container of water on the floor under the work rest?
It cuts down on sweeping and catches most of the sparks. A lot less of a fire hazard.
your machine is nice and quiet in operation . . . how nice is that !!!
I WAIT FOR THE PLANS, OF ALL SANDERS, THIS IS THE ONE THAT I LIKE MORE.

Nice work.
The belt tracking issue can be controlled by making the two front wheel barrel shaped.
markspc1 When rollers are shaped like that they are called crown wheels because they have a ‘crown’ (or ‘high spot’) in the middle. And he did do that, on his belt grinder, somewhere around the 18:00 or 19:00 minute mark in this video (I’m at 21:00 and it happened a few minutes ago)
at least now your wife can think your keeping fit when you tell her your! using the treadmill ! lol great build bud ... Lee
