This is a 2x72 belt grinder from steel tubing and plate. I based the design on Dan Comeau's build. I modified some things to make it work for me. Instead of .188 wall tubing I used .25 and filed the weld seams. That made for a much better fit. That said, his design is really great, and makes a good place to start. I had fun with this one. Hope you enjoy.

Are you kidding me, you used the flywheel? Oh, that’s brilliant. Thanks for sharing.
Great build! Most people would have edited out the breaking of the drill bit at 10:09. i appreciate you leaving it in - just to show watchers that they shouldn't expect everything to go perfectly well.
Thanks Daniel. Yeah the reality is, thing won’t go right always, and that is okay. Just keep moving forward. 👊🏻
And yet another reminder about how important Safety Glasses are...even at the Drill Press!
I have watched a ton of these builds... This is by far the most well put together video. I appreciate all the links too.
Hey Zack thank you so much. I work really hard on these videos and I enjoy the process so much. It’s great to hear you took something away from it.
Mad props for having amazing maker skills!
Really simple and affordable but effective design. I'm definitely going to plan for this. Subbed!
Hey thanks! Looking forward to making something with this!
Something worth making with my everlast welder. Thanks for the video.
Yes and not a tough build either. I’d like to see it when you’re done (or in progress). Email me some pics: brian@housework.us
soo good اتمنى لك التوفيق دائما
Very impressive enjoy your work
Thank you very much!
Very nice, sweet and simple.It looks very solid.i like it.
Man, this is probably one of the best videos out there on the topic. Excellent work! Very detailed. Great editing. Thanks for putting this out.
Hey man! Thank you for saying so. I really enjoyed putting this one together. Glad we have connected here and on IG. One day I’ll make my first knife. Hopefully soon. Watching channels like yours have really helped and inspired me. Thanks for the encouragement and support.
@@HouseMadeUS I also really appreciate that! I'm sure you'll be great at it!
Awesome work great video...love seeing you working with your kid at the end
Thanks Mike. Yeah he helped throughout. He is my shadow and picking up some skills. I really enjoy working with him in the workshop. I appreciate you and thanks for watching and commenting. Have a great day/weekend.
@5:26 when you stuck your thumb in that tubing... I was like "game over man!!" whew
Hahah! I've still got all 8 1/2 fingers. All set! :)
This makes sense, a treadmill motor is really strong at any speed. Use the speed controler that comes with it.
The controller that probably came with it not only has a soft start which gets annoying but most certainly uses PWM pulse width modulation for the control side which unless you use the big original control panel is more difficult and expensive to fake. The setup he used here works great, is cheap and has none of the treadmill safety BS to deal with. Nice job!
Good design, well done !
Thank you very much!
Made that look simple! Now I’m looking for a threadmill motor lol
its Mike Levalley great work man!
+LFP LeValleyFamilyProductions - Thanks Mike!!
heck of a build
Hey thank so much. I appreciate that.
thanks for the video answered a few questions, but the age old question is which pulleys are flat and which are convexed
Drive wheel and tracking wheels are crowned. 🤙🏻
Great video and great work, it sounds and looks great. It seems to do a great job. I like the way you ordered everything cut to size, not a lot of scrap material laying around after you were finished. Thanks for sharing this information and your skills it put some great ideas in my head. Would you be willing to share the sizes you ordered so I could duplicate what you built, I think it's a great design and really nothing needs to be changed. It is fine if you can't.

berry good~
So I spent a great deal of time trying to weld a tube on for a drive wheel and haven't gotten it running smooth yet. I see you just used the wheel on there. I didn't realize that would work!! lol
If you all watch this trying to find a design to build one of your own you should look into his newest design. It’s his own design called “The Revolution 4”. Like I said 100% his own design and it’s awesome and budget friendly. Can’t wait to build mine. Still saving but it’s no where near the cost of a new one you find online. So shouldn’t take to long if you have to save the money like myself.
What spring did you use for the tensioner/tracking arm?
Great video! I would be worried about the metal dust getting into your control panel box

Thanks so much for sharing this list with me, it will help me tremendously. I forgot to mention that it's good to see your son in the shop it's a good thing to start them young and slow so they learn the dangers each piece of equipment has. Thanks again.
Can you build one for me?
Not exactly sure why you have dislikes on this video..........it's a good video. I personally enjoyed watching. I went with a gas piston on my belt sander, just preference.
Thank you for watching & commenting. Yeah you can go either way on the tensioner.
"hello .. nice video and fantastic things you build with precision and attention ... I have a 1.13 kW 1 HP engine with 2800 rpm. Not much, but unfortunately I don't have anything else at the moment. Some read various information on the Internet and say that it is necessary to have an average speed of at least 24-35 meters per second of the tape. What type of wheels and diameter do you recommend for my engine? Thanks in advance. N: B: I'm sorry if my translation with Google is incorrect, but I hope you understand. "
nice build
Thanks Casy.
I noticed that the wheel of the treadmill motor drive wheel is thinner than the belt. If you want to get the most life from your belts, then fabricate a wider Drive wheel. Great job overall, I enjoyed watching it.
Nice! Have you had any issue with using the original treadmill wheel as it is so thin? There is a vid with a gentleman that heated a pipe and sleeved over the original for making wider. Worked really well but finding fitted parts, a beatch. Still looking at designs and trying to save the $ on wheels. found a nice 8in hand truck wheel at Amazon you may be able to use for knife other... .. . Much cheaper than the real thing. NK WAW8 8" x 1 5/8" Aluminum Flat Free Wheel for Hand Truck 5/8ths rod. It may be useful as an addition.
No issues at all with the wheel being so thin. So far. I did blow out a brush on the DC motor, I believe that's because its got a lot of hours on it.
NO MUSIC? thank you. Great info, great job.
Thank you sir! 😁👊🏻
I love it ❤💯
very cool. im planning on building one like this, got the motor and controller already. could you list all of the hardware you used? the list of the metal is very helpful and i will be taking it to my local metal dealer. thanks!
By any chance, did you get some dimensions, materials used? Thanks!
@@dignitas1980 he lists all the steel used in the bottom of the discription, what i was asking for was a list of various nuts and bolts used. i didnt get it so i had to go through the vid and count out each one and make a list. hope this helps.
Good day, Do you provide the plans for this build, as in the link above it is for the Revolution one. Thank you
Awesome video on making the belt grinder!! I do have a question. What size/kind of spring did you use for the tensioning? Thanks
I just bought a 4” 30lb spring from ACE hardware. They have a bin there with all kinds of springs. $3.00 or so. Tossed it down into the vertical cavity and the tensioning arm rests on top of it. I had video of that but card became corrupted so I couldn’t use it. But it’s easy to figure out.
Nice build, that wrench for tracking is pretty sweet... I'm still interested to see how that treadmill motor works out... DC has a higher starting torque, but AC has the better overall torque which is needed for grinding. I've seen a lot of guys in forums start out that way, but none that said it works out, but ya can't believe forums anyway... Awesome build though, watch out, if you catch the knife making bug, it might never go away, hahaha... take it easy...
+Dave Evader Knives - yo Dave! Yeah I think at some point a more heavy duty drive train would be better. This one taught me a lot though. That said I have yet to see any loss from really pushing it through some steel so who knows, it may just work out. I’m excited to get started with knife making. And building the tools is a fun path as well. Thanks for watching, being positive and supporting what I do. You’re the best. And if anyone following my channel hasn’t seen Dave’s channel, you should check him out and subscribe. His energy and videos are really great. 🤘🏻
@@HouseMadeUS Thanks, really appreciate that... Definitely interested to see your progress
Not much progress today as I dropped a damn screw onto the SCR controller and popped the circuit. Never a dull moment. Funny too because my buddy Mike said I should cover the holes because of stuff like that. I was in the process of doing that when I dropped the screw!!! HAHAHA. Should have unplugged it. Another one is on order. As if I don't have anything else to do. LOL.
@@HouseMadeUS Yeah, damn Murphy's Law, that S.O.B gets me every time too, hahaha
thanks for sharing,great video Brian...........new subscriber.thanks ..
Thank you Ray. Happy new year to you also. Thanks for watching and subscribing.
Got my treadmill disassembled this evening. I swear this used laundry hanger might have 5 miles on it...tops. Everything on it is in new condition, drive belt, lift motor even the walking belt. I was going to try to incorporate the electronic controls for the grinder, but I like your other design better.
Let me give you some good advice. Use the controller that came with the treadmill. It’s easier and cheaper. (Not prettier) bit it works well. Let me know how it goes! 😎
@@HouseMadeUS doh!! I'd already sold the controller on Ebay :/
Just picked up a bargain treadmill. Can't wait to get started building. Any issues using the treadmill wheel as the contact wheel. And do you think slightly thicker than 1/4" plate Aluminum will be strong enough for the "D" plate?
No issues, and if you want to see someone using this setup x2 check out my buddy Mike Levalley on Instagram. He has some cool treadmill driven grinders.
Great job. Enjoyed the video. To the point. I noticed your mill drill has a mod in the front of it. What is it and could you send a picture of it.
+Patrick Lucki - Hi Patrick, do you have Instagram? If so there are a lot of photos in my feed of my mill. @house__work - two underscores between house and work. Or the link is on my KZhead home page. Or shoot me an email brian@housework.us and I’ll send some directly to you.
Great build, is the wheel on motor cross threaded? If so why isn’t it flying off when on? I based my build on this video thanks you. I started w a a/c motor but burned it now I’m trying a treadmill motor.
Thank you very much for sharing this video. I just subscribed. So you used the flywheel for the belt roller. Very cleaver. Have you had any problems doing it that way so far?
Hi Tom, if you have a minute watch my latest video the one I put out today and it talks a lot about the new design moving forward and the motor of choice. Also if you look back in my library you’ll see a video called why I switch from DC to AC and that should explain quite a bit for you. Thanks for watching and commenting.
Nice build. I share your desire to have one but unwillingness to pay to buy it outright. I also checked out your video on the SCR+Rectifier, which is a clever idea. I have a spare treadmill motor and will be trying this out myself. FWIW, the seller you linked to for the SCR apparently realized that they're getting the link traffic and raised their price. Can't blame them, I guess.
Great work ! Is awsome to see a pro work! Could you tell me what brand and model is your milling machine? I'm looking to get one and yours looks really sturdy and precise.
Thanks Daniel. It’s an ENCO 105-1110. Great machine to have. There are many clones out there made by many manufacturers.
Hey , nice work! I have a question. I designed a similar sander but have some problems. I needed a deadhead for sanding my guitar necks. It causes a lot of friction even with graphite cover. So the drive wheel needed to have a rubber tire on it to move the belt without slipping. That is fine although this thing gets hot after 10 minutes or so and the rubber has broken a few times. I see your belt is driven by a narrower wheel than the belt. Does that cause any problems?
I’ve not had any issues. I found a guy on IG that didn’t use a rubber drive wheel so I reached out to him. He had been making knives for a couple of years using the flywheel from his treadmill motor. No issues and he makes 3 knives a week. Heavy use. One thing you will want to do is make sure you filter the air going into the DC motor. They are one big magnet in there and will pull in metal dust, ultimately destroying the motor. I also built a filter for the electronics. Other than that it’s exactly as you see it in this video and grinds really good.
Hell yeah man, that’s badass!!! How have u been? And the one thing that I would tell u that I liked about ur videos before is that u used to talk in ur videos and explain a little bit about what u were doing and why u were doing it!! It kept me more engaged in the videos and now it’s like ur just building something and putting it on time lapse and hoping that the people like it!!! I like all ur videos but I will be honest I liked them a little better before cause u were engaging with ur subs more that way then this way!!!
I plan on doing an explanation video on this one. I know people will have questions about it. I am experimenting with showing the process first then coming back after some comments have been submitted to answer any lingering questions. And when I watch the numbers, it seems that most people DON'T want to hear me talk or explain things. But who knows what that means. LOL. As always Mark thanks for watching and commenting. And I am doing great. Chugging a long nicely down here in the dog days of SUMMER. Hot AF. Hope you're doing well.
House / Work dang that’s crazy I would’ve figured that people would want an explanation on what u were doing and why but numbers don’t lie! But man I’ve been good, doing that same thing just chugging along living one day at a time!! And yeah I live just northeast of Tulsa, Oklahoma and yeah it’s been hot AF here also!! Just a couple days ago we had NUMEROUS days of 98 degrees with like a heat index of like 115-120! It’s humid as shit here also just like Florida! But man keep them badass videos coming brother!! And oh yeah I figured u would’ve convinced ur wife to be in a video by now lol! Keep chugging big man, can’t wait for the next vid!!
Mark Morgan - since you’re so close to Doug Jackson do you follow SV Seeker? He is building a sailboat in his front yard, really cool channel.
House / Work no I’ve never seen it, I’ll have to check it out most definitely! Do u happen to know where he lives?
No I don't but its near Tulsa. Did you find his channel?
The version I saw at our local knife shop was a wet version. How difficult is it to add a small water recycling pump?
Nice build and great video! Maybe I missed it, but are you using a PM motor from a treadmill? I'm guessing based on the bracketry and choice of motor control.
Yeah it’s a 2.6HP motor from a treadmill and a SCR motor controller.
Nice Work!! Subscribed! But would it be better if the transformer can be covered to prevent the metal dust go inside?
If you watch my follow up video I show how I filter that control box. Here is a link: kzhead.info/sun/achwoMOZrXR6p4k/bejne.html - Thanks for watching and commenting!
Those cone bits are beasts.
Yeah man they are. They work really well and don't dull easily.
Good video! The upper box section is for the paten but but what is the lower box section for?
That lower tube is for a work rest tooling arm. If you take a look at my latest design you can see how it's used. Really useful!
Like the "Kit Build" a deeper drive wheel to accommodate the full width of the sanding belt would help with belt-life. I think your power solution for the DC Motor is a "short-circuit" wanting to happen . Your going to have metal particles flying all over the place and they will short-out your electronics circuit board, that fan is feeding them to it...Good Luck!
I learned a lot from making this grinder. DC wasn't worth it. But it helped me get to where I am now. Thanks for watching.
I’ve got a 90 volt, 2.25 hp treadmill motor, almost unused. 90 v is lower than I expected though, will this be a problem?
@13:50 mentions a separate video for the electronics involved which is what I'm after.. does it exist? I did find a wiring vid on your channel but that was for a 3 phase AC motor, not the power solution shown here
Morning, just starting out. I had a small 20x20 mini shop built and I have no tools yet. Just wondering what it would cost to manufacture a 2x72 belt grinder with a treadmill DC motor and shipping? That tool is beautiful that you provided on KZhead. Hopefully I hear from you.
These aren’t for sale yet but you should watch my latest video. I am designing another. Much better, more features etc. thanks for tuning in.
I'm curious if there is a futher use for the lower horizontal tube?
I have yet to use it but it could harbor a bigger better work rest. Good for height also.
I really like the idea of the treadmill motor to power the belt grinder/sander! Was wondering what your opinion is seeing as how you have built a lot of these? thanks!
I don't recommend it in this environment. The magnets pull steel dust in and fry the motors. It did get me going though. Now I only use TEFC AC motors.
SWEET
Thanks Sal. 😁👊🏻
Olá amigo, gostaria saber se pode me ajudar? Tenho um motor de esteira DC 90v 17A. Tem 3hp e 4400rpm. Gostaria de saber se você pode me indicar os componentes corretos e se possível me ensinar a monta lo. Obrigado
a great build. thanks for making it. may I suggest that the location of the vented box with the electronics near the grinding will have a short life as the grit will find its way into it. I suggest moving it or at least placing it within a shielding box. it will get less ventilation and possible overheating depending on the design of the circuit. however grit protection is needed.
Hey Charles, yeah I ended up moving that box around, for that exact reason. It makes sense to not have open grates where dirt and dust can fall in. I just didn’t think about that at the time!
I’d be interested in building this! Very cool. Could I purchase the plans for this setup? Your newer design is awesome, but I prefer the simplicity of this one. Thanks
Hi Josh, look up DC Knives on Google. Dan is the one who designed this grinder and offers the plans for free on his website. He is in Canada.
I just found and subbed to your channel.. So basicly this is a way to be able to use a tread mill motor with out it failing due to dust? Martin
Well no this doesn’t solve the dust problem. You can do that with filters and such. There is a guy on IG named Mike LeValley and he has some neat ways to filter the dust from the dc motors. I have since swapped this motor out for a sealed AC motor and Vfd but the DC motor gave me a great start. I am going to use the DC motor on my lathe, where the dust is more like chunks.
Very nice; too bad you couldn’t find some scrap steel to cut costs further. Do you have a way to adjust the belt tracking? It looked like it was offset a bit.
I’ve seen guys build these with old weight benches. That seems to work as well. I really wanted a heavier tool so it made sense to go with what I got. The tracking is off just slightly, I have yet to really notice any issues with that though. I’ll make another video when I put together my first knife build. Thanks for watching and commenting.
@@HouseMadeUS you gotta check out your local metal supply outlet! Mine (Alro) would have had everything you needed for pennies a lb, ya just gotta cut it yourself. It probably would have cost ya $25 in total, and they'd have had all the exact sizes you needed as remnants. Great build, though!
Excelente...medidas?
ok just found this video very similar to my belt grinder. But I don't have it on a metal plate base I wish I did, I made legs to bolt to my work bench .
Yeah that plate makes it easy to move from work surface to surface without having to re-align everything.
You have some great builds!
House / Work yeah I built mine at this one job I used to work at lol, had to be able to get it out to the truck without the whole place seeing it , hell everyone was building stuff there on the job , might actually buy a plate or find some scrap and do that .
You probably won't be able to answer this for a while, but does the fan push metal dust into the electronics over time? Could you put a compression type spring under the adjustable pulley riser to tension the belt? I have almost all of that metal ready to go, you gave me a project to work on. Thanks!
Yes the fan does suck in metal dust so you will want to put a filter over that. I made one from a candy container and a horse hair air conditioning filter. Works pretty great. And yes I used a spring under the tensioning pillar. I got a 4 inch 30 pound spring from Ace Hardware. It was three dollars. I’m glad you are working on a project! And that I was able to inspire you to do so!
Thanks for the quick reply. Cool. I'm glad I wasn't too far off base. Good stuff, man.
48/5000 good job! Could you pass me the engine link?
The motor is from a treadmill. I don’t have a link for that one.
I thought that heavy wall square tubing had a welded seam inside that would prevent using it as a receiver for the tooling arm. Do you order something special to get the heavy-wall square tube so that it is smooth on the inside?
Most all square tubing has that weld. About 5 minutes with a file and it’s gone. Nice tight fit, no play. This is the way. 👊🏻
If you buy square tubing that is designated DOM (Drawn over Mandrel) it has no weld inside. Or just ask for reciever tubing.
I am building my first 72 in belt grinder. The hole thing is built but I cant get real poser out of the tread mill motor. It spins up to speed but then i apply pressure to the belt and it comes to a stop. I am at a loss to figure out what is going on. Any help would be great.
Did you use an SCR motor controller or the original controller from the treadmill?
@@HouseMadeUS the original motor
Gostei muito. Quero saber o preço dessa máquina para a América do SUL - BRASIL- SÃO PAULO- Não tenho oficina para montar e por isso quero que venha pronta. Quanto custa?
So I tried this, got a 4 hp TM motor, hooked it up with a voltage regulator going to a bridge rectifier. It did NOT like a load, the brushed started sparking and the motor got HOT :(
@12:26 pardon the maybe dumb question, but if you run the tap all the way through, is the opposite side left hand thread now? Or is that determined by the Bolt?
Actually it still stays the same. Top and bottom are both right hand tight. Righty tighty as they say. You would need a left hand threaded tap to change the direction.
Hi Brian. I am wanting to build my own belt grinder and was contemplating using a treadmill motor with a variable speed controller similar to what you are doing. My concern is that this model won't stand up to continuous applications? I've read a lot of reviews and comments from those whose attempts to do the same were thwarted by constant circuit breakers tripping, and I'm wondering if the load capacity is overwhelming the circuit design? Let's face it, a treadmill and all it's components were engineered to operate optimally, even under extreme loads. So my concern is, why are so many others who are opting to go this route (similar to your layout) having so many issues with popped circuit breakers? I guess I'm not sure why you just wouldn't use the controller board (if it's still functional?) from the treadmill that it came out of or just purchase a new one? I understand cost wise it might not be feasible, but think of all the frustration that would be eliminated in trying to figure out the issue or having to swap out to an ac motor. Just a thought. Hope you can add to this and see how your build held up. Cheers!!
Yes I totally agree. I have abandoned the concept of using DC motors in a grinding environment. I would 100% agree that an AC motor is by far superior. Anybody who wants to mess around with DC motors needs to understand that any dust that gets into those magnets will destroy the motor. Also the brushes take a beating in this environment. Thanks for your input on this! 💪🏻😁
This is similar to what I did for mine but ended up having issues with the treadmill motor flywheel being too thin. It was messing up the belts and making tracking difficult. Experience any of that? Maybe I have it tensioned too much.
I have yet to experience any issues with the belt and the flywheel. You may have it too tight or too loose. I may end up putting on a 2” drive wheel if I can find one with a 17mm bore.
There are some treadmill motors that have 2” wide flywheels. Haven’t been able to find one though. I just bought a wheel set on amazon with a 5/8” bore. Pretty good price. $110 for 4 good quality wheels.
@@jbrou3892 Could you share a link ?
DarkKnightWong Belt Grinder 2"x72" Wheel Set for Knife Grinder 4" Drive 5/8" Bore 3" Track 2" Idler - USA www.amazon.com/dp/B07Q4M4RSC/ref=cm_sw_r_cp_api_i_AwjCDb77YDY9S
DarkKnightWong just got them in today. Looks well made. Fit my 5/8” motor shaft well. Haven’t wired up the new motor to try them out yet though.
How do the power unit and motor do with metal dust?
You have to filter the air going in.
So I ordered the same metal same place. (Not pre-cut) I just cut it myself (FYI it killed the cheap harbor freight chop saw RIP). One issue I am having if my treadmill motor. I see you didn't order the OBM drive wheel and went with the flywheel. How is it holding up? I may have to put mine back on.
Also, how is the tracking/ wear with the wheel smaller than the belt?
I had a good experience with the flywheel. But ultimately the motor failed after a couple of months so I switched it out to a 2hp AC and a VFD. If you look through my video library you will see a video about why. Mostly because the motor failed and if I had to do again would I.
There is a guy on IG @mikelevalley who runs that setup, and has put many hours on it. Check out his vids. You will find your answer there. Proof in the puddin. 👊🏻
Curious to know why you didn’t try and weld the round pipe onto the motor flywheel? Didn’t want to deal with welding to a cast part? Also curious to know how the flywheel only as a drive wheel will wear the sanding belts down. Now that you’ve had it for a few days, does the fluctuation in the voltage out of the rectifier produce any noticeable effects to the motor? Jittering vibrations etc etc.
So far so good with the flywheel. And yes I felt as if I couldn’t get that pipe perfectly welded on so I skipped it and just tried the flywheel. I notice not uneven wear or any tracking issues. I do think though at some point I will add a 2” drive wheel to it. The shaft on this motor is 17mm so I may need to shave it down just a little and move the mount over a bit to do that. I think I can shave the shaft down 1mm with a file while it’s turning. I have not noticed any jittering or vibrating with the motor yet. It seems solid enough. I’ve ran it now for a couple of hours and it barely even gets hot. I did add filters to the motor as well as the electronics. That was very much needed, and some magnets around the base to pick up metal dust.
House / Work I would recommend contacting someone from Etsy or eBay who has drive wheels for sale and see if they can make you a wheel that’ll fit your motor shaft. I’ve tried filing the shafts and boring out a premade drive wheel. Both were doable but they were sketchy running at full speed and for extended times. When I happened across another motor I had a custom drive wheel made for like $55. Makes a world of difference, as well as you can swap out to any other treadmill motor if you burn it up and need to replace it.
Wes Mischke - great suggestion. I do have a metal lathe (a very old one) and maybe I could make one myself? Might be a good video to make too. I’ll look into Etsy. That is super helpful info. Thank you. 🙌🏻
House / Work if your lathe runs true enough and you have a bit of aluminum stock laying around do it!!!
@@HouseMadeUS I'd like to see that video.
How's the motor and scr holding up?
The motor blew a brush mount, so it was throwing sparks. It had a lot of hours on it. I’ve since replaced it with an AC motor and VFD. I couldn’t get the parts for the dc motor. Brushes you can find but the mounting bracket (which is plastic) isn’t available. I’d have to replace the entire motor. I’ve since epoxied the mount hoping it would hold for another project. Thinking of using it on my lathe.
hey i bought your plans for your other 2x72 grinder but after thinking about it it would be way more machine than ill ever need. is there any chance i can get the plans to this one? i already built the motor controller and copied down the dimensions for the steel. so i just need hole sizes and locations. thanx
Hi Nick, yes I can email you the plans. I will do that today. 👊🏻
@@HouseMadeUS awesome thanks I'll look for them
@@HouseMadeUS I don't see them.... nick1209@msn.com thanx

What did you use for tension?
A compression spring from ACE hardware. Works great.
Hello, guys I want to know, which grit sanding blet is the most used?
I use a 50 grit a lot. 😁👊🏻
Where did you get the plans.. Nice work
Here are the plans I followed, be aware that I did not use .188 wall 2x2 - I used .25 wall and filed the seams. Much better fit.
thank you
@@HouseMadeUS I wanted to ask the same question about the plans. I see you answered but I can't see a link or anything of the sort. Am I missing something? Thanks for posting this!
Not sure if KZhead is stripping the link or not, but here is the link again: dcknives.blogspot.com/p/2-x-72-belt-grinder.html?m=1
DUDE howdid you make that intro?! lol Just sub'd, I'll be posting about my BMW R80 build soon, and I'm also building a 2x60 grinder with a treadmill motor. Looking forward to more!!!!!
Haha! My wife is a graphic artists and she spent like 10 hours animating that. I married up for sure!! The BMW R80 IS FRIGGIN SICK BRO. I love that bike. Any particular reason you're building a 2x60 and not a 2x72?
@@HouseMadeUS I think just compactness, I'm a hobbiest getting into light fabrication for the bike. I'm a woodworker by trade (search Rivertown Woodcraft) that went full time in that so definitely no time for KZhead, but want to get into Tig welding and fabrication to build our the bike. I'm slowly learning I might want 72 though, if not just for belt selection / availability
So you put that your tracking bracket was 1.5x1.5x3.5 but hows that possible if your tension arm is 1.5x1.5? Looks like it .ight be 2x2ike the body.. is that correct or am I wrong?
Good catch yeah the tracking bracket at the top is a 2x2 .188 wall.
Thanks.. I appreciate it.
Like!
I appreciate that very much!
what size and length is the piece of pipe you used for the drive wheel i didnt see it in the discription ?
Hi Jamie, I never actually used the pipe, but it is 4.5" in diameter. Thanks!
@@HouseMadeUS oh whoops i saw a video of someone welding the pipe on to the flywheel .. your video has legnths and metal sizes so i l saved yours so i could use the discription ..thanks for the reply :)
@@HouseMadeUS liked and subscribed btw
What was the Dimensions on the pipe for the drive wheel? I see you didn't use it.. I'm following the plans you used. I'm all assembled and some reason my belt keeps falling off.
4” pipe. Check your tracking mechanism for the belt problem.
Nice video Brian. Kick ass job on that grinder. What's the story on the awesome mill you are using? LOL
+Behind The Door Productions - the story is coming! Lol - Thanks again for the Mill, it’s an amazing piece of gear to own. I’m excited to see what else I can make with it in the future. YOU DA MAN SCOTTY!!!
@@HouseMadeUS I was excited to see you using it. So glad it came in handy on this build..can't wait to see what you build next, with all the stuff.
11:18 MOMENTUM!!
It’s the way. Always moving forward. 👊🏻
Yes you could get around it. But i love the fact that he used a grinder to make a grinder😂😂
Haha. Yep. Had that same thought. Much bigger grinder made though!
Nice Build but at 16:39 I noticed that the belt is travelling in the wrong direction
I appreciate your attention to detail. I have fixed that. Thank you.
Or maybe better yet you could do another KZhead video on it sure would be nice
Here ya go Tim: How to: Build a DC Treadmill Motor Speed Controller for $20 kzhead.info/sun/aduqga6JpX9rd68/bejne.html
Hot metal shavings and the power supply top is full of large holes.......build a cover for it stat, or you'll replace it soon
Yes sir. Did that already. Definitely needed. Cheers!
Are those smaller magnets home made or purchased? What are the benefits of using those?
They are hard drive magnets, they collect the metal dust and keep it from entering the DC motor.
I was talking about the ones you use when welding the frame.
Oh I see - these are available on Amazon: amzn.to/2sXj1Lv. Or the flexi ones - amzn.to/35O7lcT - I use them all the time.
Thank you
Really should cover that controller with something, metaldust isnt good for it...
Yeah I totally agree, I added a filter to the box so now it’s sealed. Thanks for the comment and advice on this.
Is your tensioner wheel not turning?
+Mike Kaine - it’s spinning you just can’t see it in the video. Spins nice and free.
Can I buy a grinder belt m all its accessories
Yes you sure can. eBay has a bunch as there are also a lot of manufacturers that make them and sell them.
No argon at the 7 minute mark ?
Yep, tank was shut off. Good eye.
House / Work “Don’t ask why I know what that looks like....”
Haha. Yep. All welders do.
Can you please send me the plans please ican make this tomorrow as work slow. Please send me the plans
Check out DC KNIVES they have detailed blue prints on line. Just use .25 wall and not .188 for the main body.
