I Built A Better Belt Grinder…Here’s How

[@TimWelds]

You can learn to weld. I'll show you exactly what to do in my affordable online welding courses at courses.timwelds.com.

[@calimesacox]

Where'd you get the wheels the motor and speed controller

[@harrypehkonen]

I work at a metal fabrication shop. I have designed and had laser-cut a couple of parts already, but I really want to put together a kit like this at some point. Thanks very much for the inspiration! For those who have not seen them (like me, in the past), having precision-cut locating tabs and holes are amazing!

[@sander33688]

Do you need this belt grinder

[@mikepierson3097]

Dude, that is a really impressive build! Very nice work!

[@maxw576]

Nice build! I built a 2x72 I designed a few years back. Very handy tool! I integrated a variable height stand for standing and sitting use and a few accessories with mounts. I used wood templates and cut with a hand plasma cutter. Wheels were expensive at the time so turned my own using a HF lathe and radius tool mount I made. It was a very challenging project for my amateur capabilities. I'm very glad to see you sharing your design and making it easier for people who would like to build one.

[@SS-ws8bf]

Mr. Tim, I'm a new subscriber. I just want to say that your idea to include the plans in a single link is revolutionary and excellent. It's like you're the new Popular Mechanics! Seriously! THANK YOU FOR DOING THAT! This is on my 2023 must do list. Impressive welding, too but I REALLY want to commend you for this list. I'm glad I subbed.

[@vulrath31]

Thanks for the video! I don't comment much (if at all), but found it important to share my thoughts. I'm in the process of building this right now, and I'm going to share a few things I've learned so far about fabrication in regard to this project specifically. 1) The threaded mounting holes on the motor are only 1/2-3/4" deep and are blind. Don't thread a 1" bolt in there and keep cranking. Ow. 2) The holes are all 3/8" as drawn, but the linked rollers are designed for a 12x40mm (I would take it to the hardware store and double check that) shoulder bolt. You could do what I did and drill it out to 10mm and get a lock nut, or you could thread it for M10x1.5 (I think that was the thread I was able to find in the hardware store). If I were to do this again, I'd have waited for the rollers to get here before I bought anything else, and definitely before I paid for the custom cut plate (which is indeed very nice), and used what's available to guide my choice on what size to thread the hole. A simple thing that could have alleviated most of my non-welding woes. [I just double checked and it should have been threaded from the start. I'm actually more satisfied with how I did things like this than if I'd done it as designed. If you get the plate as drawn you can still tap it yourself pretty easily.] 3) There are a few options for 120v input. I just grabbed the cheapest. Input is usually listed as RST on the VFD - for 1 phase 120v input hot is R and neutral is T. S is used for 240v, and ground is its own lug. 4) You don't need a ton of the 1-1/2" square tube. Maybe a 4 foot section tops, if you're thinking about making multiple tool rests. I didn't think about what I was doing and bought 8 feet of it. 5) You can make life a little easier by using KIPP style toolless screws (ratcheting handle screws) for the 4 side adjustment screws. 6) I think it's definitely important to build the frame Mr. Welds has on his, but I also think it's a good idea to go to Harbor Freight and buy a $60 grinder pedestal for this thing as well. This way you can still move it around, but you don't have to do as much lifting/fighting with it when it comes time to use it. I have more than a few tools that I dread using because I don't want to fight with getting them out from under the work bench.

[@deemstyle]

Great comment- thanks for sharing!

[@warrenmusselman9173]

I've been on the edge of building a 2x72 for the last 2 years but have been torn over the space it would take up in my small shop. Until now I haven't seen a decent design for a 2x48. Many thanks Tim - this is now on my to-build list although I may make a few mods in order to use a motor I already have.

[@TimWelds]

Awesome! I've helped build a few 2x72s for friends and have had the same hangup on the space they take up. I figured I might as well just make one that will work for me.

[@bennyb.1742]

Well, this is on my project list now. I'm building a new shop after the loss of my previous one and I'm having a lot of fun making most of my own equipment and furniture. This grinder is awesome

[@JakeyBabesxXx]

It's rare to find a build in KZbin I actually like. I love this

[@Tinkery]

Sweet build! That is exactly the kind of grinder that I’d like for my shop: lots of flexibility, small package, and simple bullet proof construction. Well done!

[@westvirginiamm9802]

Nice build your a good teacher I watch your videos daily I get something from every one of them

[@migs1121]

I'm almost done building mine. for a weekend warrior like me, this is a great project. Two things, my motor does not have a flange to mount it so I have to modify the design a bit. Second, if yo guys need bolts I recommend the Bolt Depot. Great prices without having to spend a tone in shipping!

[@toolteardown1]

Wow, home made tools are always a dream when done right. Solid build quality, practical features and designed from experience. Great job!

[@onefortheroad2291]

5:30 “I’ll go ahead and weld this on like a boss”. That you did sir

[@PharaohMoan]

Man! This is such a beautiful, compact, practical design. Started my 2x72 build, and as far as I’ve gotten so far is the whole front end (platten, rest, etc.). I may just have to make this design the back end to save space. Thanks man!

[@barrylinkiewich9688]

I work in a laser cutting shop and I've built a 2x72", I love it but dang it's a LOT of machine and definitely NOT portable; I can lift and carry it but I need a pretty good reason to do so. It also takes up a TON of bench, and floor space in front of it, it sticks out a good 15-18" beyond the edge of a 24" deep bench. Honestly, for general shop and fab work something this size would suit most people much better so I really appreciate you uploading the files, I think that's the push I needed to finally build another and downsize to something a little more manageable.

[@andrewfung9614]

i feel like these 2x48 belt grinders are useless to most people but the people who need them or covet them find incredible use for it. Ive been dreaming of one for a long time and this video gave me the inspiration and realization to realize i have everything i need to build one myself.

[@InchFab]

This is what I needed in my life, Tim. Always love your projects, and I'm all over this one.

[@korkie17]

Tim this is such a cool build! I can't believe this is the first video I have seen on your channel. Really cool stuff going on here!

[@TimWelds]

Thanks Kendall! Hope you and your family are doing well!

[@gordonvanlieshout8134]

Impressive! Quality workmanship.

[@xylemmelyx]

Sweet. You built in 12 minutes what took me a mere 7 months to do, and I suspect yours is a tad better than mine. :-) Great vid. Thanks.

[@Yaroslav_Tselovanskyi]

Very nice build, I like that you used MIG/TIG depending on the situation. One thing I would add is a counter nut for the tracking adjustment screw, maybe a nut with a tiny lever welded to it so you can lock the tracking screw in position firmly after adjusting it.

[@rogermccaslin5963]

I was thinking a coil spring slipped over the screw just to give it some resistance against vibration.

[@alanrichardson7244]

I’m really impressed. Especially with your dog table. It’s beautiful👍

[@AubMar]

You've kept it simple, the key in engineering, Thank you for sharing here, beautiful work!

[@LaceyOGrady]

Your vocabulary is amazing, I learn so many correct names for things in your videos. Fantastic work!

[@stephenschwarz7185]

I love this! Would be a perfect project for someone wanting to practice their welding skills for a real life use!

[@johnforeman4393]

Very nice and compact grinder build! Do you have a list of the hardware & bolts you used?

[@sayeretmatkaal]

Oooooooh ! That's a BEAUTY ! Well done !

[@jaredharper5786]

I think this will be one of my first at home projects once I get my welder

[@deadcarz4926]

Thanks for the plans and the video.

[@millarfarewell5343]

Hello Tim, I really like the compact size of this Belt Grinder. So I'm building one. Can you tell me what length of 1.5 x 1.5 tube you used for the platen and work rest? From the images it looks like they are about 12" and 15" long. I also want to thank you for the free dxf files. I was able to cut out most of the parts on my cnc plasma table with only a few needing to be cut out on a laser table. I didn't know that you could get 220 volt 3 phase power out of a frequency converter with 120 volts input. Thanks for your excellent design and build instruction video.

[@restorick2378]

Hello - just saw the video for your 2x48 grinder. Unfortunately, I tried going to the link you had on the YT video and the page was blank. Have the dxf files moved to a new location?

[@carrerasjuanito]

Great work Tim. I think I will use your design as ''inspiration''' to build mine

[@mihailapetrudorel3289]

Muy bien hecho,me gustaria tener las medidas de las piesas cortadas en laser, un saludo.

[@3campingguys431]

so for the person who is NOT a CAD software user, is there a way to get the templates in a pdf or similar where i can just print to size? thanks

[@johankralt5318]

hey Tim, nicely done! definitely a big inspiration to make my own. Thanks a lot! greetings from Amsterdam.

[@markkusuurinkeroinen2098]

Very nice👌. I was going to build Jeremy schmidt belt grinder but when i saw this. I Have to think again... Looking forward to see upgraded table🤩

[@melgross]

Very nice Tim. I’ve wanted to make one, but haven’t gotten around to it. The only thing I would suggest it to use something to cover that A-36 belt back plate. You’d be surprised how quickly they wear. Possibly a graphite sheet used for that purpose, or next time, a steel with good wear resistance, such as AR-400.

[@dennisyoung4631]

Perhaps a replaceable strip of UHMP? (What I had thought to use if I ever managed a grinder build.)

[@cae2487]

Why not just buy a ceramic glass platten to put on it. I'm pretty sure it's like 20ish bucks for one.

[@melgross]

@@cae2487 I don’t think I’ve ever seen a ceramic platen for these kinds of sanders. We’re talking about metal. There’s a lot of pressure used for metal. A ceramic platen could crack from the high point pressure and heat.

[@cae2487]

@@melgross go take a look at pops knife supplies they offer those plattens for sale. They can break but you'd have to really be slamming your work piece into the belt but as long as you are using it like a normal belt grinder you shouldn't have any issues. You cam only push so hard against the belt before you are going to bind it up or put a whole butt ton of heat into your part. Knife makers have been using ceramic platens for years because they last longer than steel platens and they don't heat up as fast as a steel platen would.

[@melgross]

@@cae2487 for,knives, I suppose they might be ok for a while. But for anything else, we really push it. They wouldn’t last.

[@JimmyJamesJ]

WOW! Great work. I've done a similar belt grinder project but mine is not as nice as yours. The only comment I have is you've made a mistake mounting the VFD to the frame holding the motor. I've seen many VFDs fail prematurely from vibrations caused by being mounted to the motor frames. The vibrations cause the solder joints in the circuit boards to fail. Other than that, I love it.

[@davevick1775]

Nicely done and thank you, however maybe a note with the .dxf files specifying which holes in which parts need to be tapped would help.

[@JoeMalovich]

This is fantastic! I'm interested in if you have any updates or modifications you've done? Maybe a fixed base that allows the grinder to hinge over for horizontal grinding? How about those other tables?

[@vikingironworks9261]

Awesome work mate! Loved the look of this and might have a go myself. Cheers from Australia 🇦🇺 😎👌

[@jeffsession1982]

Do you put the sand paper right on the machine or there's something flexibly round to put the sand paper on it to use? Thank you.

[@ruslangabitov5202]

Thank you for sharing. Great idea for horizontal - vertical conversion!

[@sirtooby]

Wow, thanx for sharing this information. Looks really well built. Smart when smaller and when you tilt the grinding you do it by tilting the hole assembly. Hope I can find a business tha can help me with the parts

[@sleepib]

If you weld a bearing ball to the tip of that tracking adjustment screw it should feel much smoother.

[@laurencewatanabe]

Very nice i like dis how much if order all part sander belt

[@buckw65]

That was amazing. Nice work

[@chainring_tattoo]

Great job, Tim. I really enjoy your channel.

[@JCWren]

That's very slick! What was the total cost of the project?

[@mattyoung5084]

I second this question! Would be helpful to know.

[@brianleduc7797]

Very nice belt grinder I'm like every one else who watches projects never say the cost or were to buy the kits clearly

[@tylerkrell399]

@@brianleduc7797 He put the entire project in the description.

[@TimWelds]

The total cost was about $600, though I already had some square tubing on hand. You could save some cost by using a single phase motor without variable speed. The big ticket items were: Laser Cut Plates: $150 Motor: $220 VFD: $90 Rollers: $70 @Brian Ieduc As far as kits go, I designed this one from scratch, so there is no kit right now. Most of the major components are listed in the description as well as the CAD files for the plate work. There's also a link to add all the plates to a SendCutSend cart.

[@JCWren]

@@TimWelds Cool, thanks. Now all I need to do is get skilled enough with my TIG welding where I don't need to order 7 sets of parts from SendCutSend :)

[@crossgrainwoodproductsltd9230]

Now here I thought in North America we couldn't run 3-phase motors without a converter. I'm baby new to this, but I really want a belt grinder so I'm absorbing as much info as I can. This is very sharp looking! Lucia's Shop built a very fancy one. You should check out her channel.

[@georgegriffiths2235]

Do you have a set of plans for those not in the US

[@TCHamilton56]

Hardware Hi Tim - do you have a hardware size/count for this project - I'm fairly remote so I'm trying to avoid going back and forth to store. Like the project - looking forward to putting it to work Thanks much

[@wesleemiller]

Great video.

[@homemadetools]

This is a better belt grinder! We shared this video on our homemade tools forum this week 😎

[@tribum]

Very cool! I watched some of your earlier videos a couple of years ago. You're welding like a pro now bro! Kudos!

[@6Sally5]

Super job! So…aside from it being custom designed, is there any savings between building yourself or buying an off the shelf similar grinder?

[@TimWelds]

It's not quite apples to apples with those on the market, but it ended up costing around half what I would have spent for a comparable off the shelf unit, not including my time.

[@Yousoundvaxxed]

As a knife maker, that’s an amazing grinder for those who don’t have much space!

[@jaspercallahan3318]

We do industrial work and do alot control cabnits. We use drives from automation direct. Great drives never had any issues.

[@deemstyle]

Nice build! Did you mention the vertical height of this grinder once finished? If not- can you let us know? I want to see if it would fit into a 15" tall cubby

[@kennethtencza9209]

Very nice, simple, strong, excellent 👏

[@-DIYPRO-]

[@TerryBeatson]

Looks like a practical addition to your shop, great work Tim, keep the videos coming

[@civhonbmm3]

Wow that’s nice all I need a good size workplace and skills todo it go back to learning again.

[@njbaquatics4827]

Love the compact format of this. Did you ever get round to do it any more designs for different to rest and maybe a contact well?

[@buckwheat7424]

i built a pretty sweet bike stand for a xr650r out of a bed frame on the side of the road without any detailed measurements. it looks like hell, but it works as i only have running a 115v millermatic wirefeed, at the highest voltage it still struggles on much more than sheet metal. like trying to weld a nut onto a 3/8" broken bolt is tough. something about the chinese steel bed frames it welds them with ease, a little splatter but at least it gets some good joints. weird about the welder is it'll weld beautiful looking beads on stainless with flux cored wire.

[@DougsMessyGarage]

The belt grinder project turned out great.

[@nuclearmelon7817]

Hey Tim love you're content. Recently bought your mig/flux core and basic fab course and they're great in the future I would love to see an advanced fabrication course and maybe a deeper dive into cnc

[@TimWelds]

Thanks!

[@jiriskala]

So the whole grinder body hangs on the flange of the motor? Isn't it putting a lot of stress on the motor case?

What gauge steel did you use? I’ve designed a lot of tab and slot stuff, it’s really great! Wish I had a welder at home haha

[@dennisyoung4631]

The listing at where he had the pieces cut indicated 1/4” inch hot-rolled, pickled and oiled steel.

[@BenNawrath]

@@dennisyoung4631 good eye! Thanks.

[@machmat33]

Love the compact build and just tilting it on its side is genius.... so simple. Have two comments.... the availability and cost of 2x48 instead of 2x72 belts. 2x72 belts are so common, in such a wide variety... I don't know about 2x48 belts. Second Comment.... I can't see that controller lasting very long sucking in grinder dust. Bad in the vertical orientation and terrible in the horizontal orientation. TEFC motors are pretty well sealed and in my experience can take a lot of abuse. Maybe a VFD in a watertight enclosure? Nice design and I never thought about using a laser cutting service.

[@TheWildPursuit]

I’d love to see a video or small series on basic cad and showing how you use onshape.

Yeah, another project! Thanks Professor Binford.

[@TimWelds]

More Power!

[@jerrywilson1917]

How long do you cut the 1 1/2in tubing for the idle pulleys and platform holder?

[@retired_badger]

I've bought the "kit" from the link, and by my estimation the idle pulley tube is 9-10" long. The side box plate is 5" in length, and it looks to extend about 4-5". The platform is 3" deep, so if the other is 9", I'd go closer to 14-15". I'll post here once I get my build started, if you don't get a response otherwise.

[@retired_badger]

Got the build started, and very close to running. The idle pulley tube is 8.5”, and the platform is 12.25”

[@jerrywilson1917]

@@retired_badger Thanks that helps a lot!!!

[@mrt7512]

Hi Tim, appreciate the work you put in your videos, nice looking belt grinder. Do you have any tips when cutting miters on 4x1 tube? So they don’t go out of square? Thanks

[@johnjohn-pt7pe]

Nice build, is the VFD 120 or 240 volt? Which VFD would you recommend for 3phase to 120 volt? Thx

[@TimWelds]

Mine is 120 volt. For the VFD, I just bought the cheapest one from Amazon. It’s working great, but may fail early because it has open ventilation which can allow metal dust in and short the circuit board. I figured I’d take the gamble and upgrade when it dies.

[@mikesnifferpippets3733]

Very nice piece of equipment you designed. Did you choose the 3 phase motor because you already had it on hand?

[@TimWelds]

I chose the 3 phase motor because variable speed with a VFD is better than variable speed options with a single phase motor. It's almost always turned all the way up when I use it, so I'd probably just use a single phase motor and a light switch if I were doing it again because that would be cheaper.

[@alonsorobots]

Tim, can you elaborate on what makes your VFD not so good? So much so that you wish you would have gotten a different one?

[@dfinma]

This is very, very impressive 🤘

[@jasonhovey815]

What a great project

[@charleswalter4907]

Tim, could you bios that 2x42 grinder for me?

[@SpottedMau]

I've been back to this video several time. Thank for taking the time. One question about the motor mount: Does the hole pattern from a 56 motor case the same as a 56c, like the one in your amazon link?

[@johnkelly7264]

Thanks heaps for the CAD files! Subbed here.

[@paulgibbs6900]

One day poor simple peasants like me will be able to afford a laser cutter in the shop. Very neat work Tim.

[@jimsvideos7201]

The only thing I'd keep in mind is that in the horizontal orientation the motor might be prone to sucking up dust from off the bench. Great looking build; I could definitely use one of my own.
