Belt Grinder Build From Scrap Workout Bench And Treadmill Motor 

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 ..

Cheapest no bullshit design and build on RU-vid, definitely gonna be using this, good shit.

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 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'm really glad I didn't throw away my little old belt sander, hehe. Nice build! Thanks for the video!

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!

Mike: The repurposing of readily available items is both economical and thoughtful. Please continue with that approach. Excellent work.

Welding the pipe on the fry wheel.. you sir gee gave me $ million idea ...thank you so very much SIR GEE

Thanks for the vid. I can see why a belt sander is what you chose to build. Well done.

That Workout Bench, really worked out well.

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.....

Using the router to make the 'trunion' is a fantastic idea. Keep 'em coming.

If a mech. engineer and a field machinist had a baby he'd be you. Wow is all I can say, great job.

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.

Very nice. That router trick was genius!

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 did a half wolf whistle when I saw the sharpened edge on that blade. Nice job, brother.

all that is needed is to add a disk on motor to make it a dual sander great build

The final assembly looks fantastic painted up. First class build.

Most well designed 2x72 on RU-vid! Great build very robust.

Hell, who needs a Bridgeport? Run what you brung, I love it.

I've never seen anyone file as fast as you do! Lightning speed lol! Great work and thank you for all the great tips.

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. Loved the router trick to slot yr aluminum. Very good build!

That looks absolutely savage and I love it. I might even make one with my everlast welder from my own old workout bench.

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 😂

Excellent work! I like that you used material you had! I never throw away metal your a good man and thank you.

Wow, that thing must way a ton, it's BUILT! Great job, it's a nice project.

Best use of gym equipment I´ve seen so far!

Nicely done, slick editing. Have fun and thanks for taking the time.

wow' I've been keeping a workout bench for a while for this exact thing. Cool I'm glad someone has tackled this.

Great job, I like it. I happen to have an unused freebie bench and treadmill. Guess what. Thanks for the great tutorial,

For sure the mother of invention, I like your "Milling Technic"; to make that slot! Nice job!!

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!

Oh great! You have golden hands! Thank you so much!

Love the recycle and re-purpose instead of the thrash and trash mentality. Thanks.

This was a great build to watch. You absolutely killed it. Improved me to get in the shop myself. Thank you!!

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

So many people are way smarter and more creative than I am. Great work!! Thumbs up!

Thanks for sharing your this machine.i might try to copy this if you don't object. Very well done and thanks again.

I saw this sander in person yesterday, its nice, good job mike, and thx for the cub, dad is lovin it.

Awesome project! And thank you for teaching me how to sharpen lawnmowerblades :D

Excellent build. I really support anyone building from scrap. Much better than seeing this material in a landfill.

Excellent job, haven't seen one this fine detailed before. well done,

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

Really impressive design and metal smithing!

Dude u did so much with so little...hats off to you!

I WAIT FOR THE PLANS, OF ALL SANDERS, THIS IS THE ONE THAT I LIKE MORE.

best use of a home gym I've ever seen.

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.

nice mig welds. It great to see a nice bead on dyi projects

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 ..

Very handsome grinder.

what an upgrade, my dude! well done.

Super nice custom built belt sander. When I come across a treadmill, using your design. Thanks

Great build! I love building re purposed stuff. Put a a treadmill motor in my lathe about 2 months ago and love it.

WOW! THAT'S AN AWESOME MACHINE AND INCREDIBLY IMAGINATIVE!

Brilliant repurpose of the bench and treadmill.

Awesome build. I'm going to try it myself. Great post.

Absolutely brilliant. Good craftsmanship.

Nice,,,I built a foot operated shrincker stretcher from my old total gym,,,better than you can buy,,,and put a treadmill motor on my atlas metal lathe,,,unbelievable how much better it performs

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

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

That's a tool to last a lifetime,..👍🇬🇧...."this thing tracks perfect,I know that cause I built it"...🛠 !..that got a sub.

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.

Using a router to make that cut! Are you kidding me! I would have never thought of that. Well done man!

One man's scrap, is another man's treasure

Excellent job there.

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.

Very nice fab work!! Thanks for the many great tips and tricks.

LOL brilliant idea with the router to cut the slot....

WOW Beautiful JOB...I learned a lot !! Thanks sooo much....Re- Purposing is the way to GO !!

Awesome build

Your talent is awe inspiring!

Forgot to say, very nice build...

awesome build. love the repurposing of the metal and old equipment. great work.

I was mesmerized watching this.

Great grinder out. Like! Good luck!!!

looks VERY professional. 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.

That is a very impressive build and you've produced an excellent machine for pennies. Thanks for sharing

You have some really smart ways of doing things

holy shit wow brilliant idea the vise and ur belt sander I never thought I even have same type of vise and belt sander. thank you very much sir. subscribed!!!!

Well done bud. Those skate wheels are just the thing for that. Oh and i love that vise...

Uses a tiny hand held belt sander to make a powerful 2x72 haha great work

I built one just like yours great design works great thanks for the idea

Great work! i caught that "F##K" when you ran out of shielding gas.

I build stuff at your level . . . .and you make me happy

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

Router as a milling machine? Brilliant!

Best use for a treadmill EVER!! LOL Excellent all around knowledge of tools/tooling and craftsmanship! You must be an electrician :)

Did I hear jump around in the backround? ... thats friggin awesome

Nice build. You have it together

Get that man a Binford Tools t-shirt!

jeez this guy is resourceful

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 ...

Man that chop saw can cut some thick metal!! 😲

Neat build. Very clever the way you weld and use a peace of pipe for the drive wheel.
