Belt grinder build 2/2: Motor, table, platen, and housing

Finishing up my belt grinder / belt sander. It can take anything from 1x42" to 2x72" belts. Using a washing machine motor.

[@jimsjacob]

Wow, that was just fantastic. For me, your ability to decipher solutions to the build is amazing. Thanks for sharing that.

[@pccalcio]

or.. you could just reverse the footage in editing to make it spin in the right direction.. lol :D

"The dust collection is so powerful it sucks in the sparks"

[@Rukatekime]

Молодец!

[@Guust_Flater]

Great video again!! 👍 Question: are you going to make separate covers (directly behind the belt) for longer belts or make the slot bigger (But than less under pressure)? Longer belts change the angle of the belt on the return side.

[@matthiaswandel]

That little cover moves for different belt lengths

[@Guust_Flater]

Matthias Wandel Aha...it slides! Thank you! 👍Is it just sitting there (friction fit?) or is it possible to fix it in the 3 positions? I would be a little afraid that, due to vibrations, it gets loose and caught by the belt and swings upwards....doing damage to you and/or machine. Just my 2 cents. 👍 😁

[@matthiaswandel]

Friction fit. If it does fly up, it will get caught by the upper wheel supports.

[@dizzolve]

Damn 3:27 is that mark on your finger from the fireworks?

[@Everlanders]

That was a very Electroboom moment...

[@albertlagerman]

2:59 electroboom! but without the swearing. Sure you could have used a multimeter to test it, but this is way more exciting!

[@jaysanwich]

Love the shot of his burned finger right after

[@elitearbor]

At least it was just soot and not a serious burn! That can always be a pucker moment, whenever anything electrical goes wrong.

[@mickenoss]

I didn't even notice that. =D

[@bluesquadron593]

Haha, just commented the same!

[@guitarslf132]

IT's only 110v in Canada, no biggie ;)

[@IceBox3]

Love the charred finger at 03:05

[@kenl5217]

There must be an easier way to get rid of drywall screws

[@billybobjoe198]

This is easily the best comment on this video.

[@billybobjoe198]

Still peak comedy.

[@fynbo1007]

Love to see your project, thank you for sharing your amazing video

[@bigginksu]

3:04 - ElectroBOOM would be proud!! lol. As always Matthias, awesome video!!

[@bluesquadron593]

My thoughts as well!

[@guganotubo]

And the black finger!

[@matthiasburger2315]

3:14 made me smile: the excited look on your face. Not at all scared by the recent mishap. Only a bit more cautious and nevertheless courious whether it might sparkle or smoke again.

[@FishersShop]

RIP drywall screw. Great job, Matthias! Love it!

[@cffellows]

Solutions to mechanical problems which would have me scratching my head for days seem to come to you quite easily. I admire your problem solving ability.

[@ronyerke9250]

My son used my bench grinder to shape wood once. We had a nice, smoky smolder going on inside the grinding stone cover the next time I used it on steel. Keep your eyes peeled for smoke and keep an extinguisher where you can get to it easily. It might be a good idea to open the dust collection chamber to inspect for problems after you use it on steel. Just a word to the wise.

[@matthiaswandel]

Not planning on using it with dust collection with steel. Too much fire risk.

[@pixelkatten]

This is why no wood is allowed in the belt sander at my school.

[@ronyerke9250]

Good plan. I'd check for dust build-up by the drive pulley before working steel too.

[@thirzapeevey2395]

Use a wet/dry vac with a half inch of water in the bottom.

[@ronyerke9250]

By the way, I didn't know he used it on wood until after I saw the smoke and extinguished the embers.

[@glasbrnr]

As always, I appreciate and admire your imagination, design skill, debugging ability, and your construction skills. Plans anytime soon?

[@mijodo2008]

Had to pause for a while after the 3.05-second mark and go and change my Jocks, take a heart pill and calm down a bit,........by videos end my heart was still racing. Thank you for leaving in the 'warts and all' parts, that alone is a good example of thinking safety first. I still put a circuit breaker and a lamp in series with all my first-time running of prototypes, especially for old motors. Top Job, cheers from Michael Australia,

[@alibronx2112]

You forgot to spray paint your name on the floor before sticking the nail into that 2x4

[@HandToolRescue]

Awesome! You could put it face down to make a stroke sander.

[@cameronknowles6267]

Hand Tool Rescue what’s a stroke sander I haven’t heard of it before

[@TJStellmach]

Cameron Knowles A stroke sander uses a horizontal belt above a moveable table. The belt is pressed onto the work piece with a handheld pad. You can see one in Matthias' "Touring Dad's Workshop" video.

[@vanstonecypher]

Hi Matthias, thanks for these videos. I really enjoyed watching you work through the problems to arrive at the final build. It makes the whole idea of building this a lot more approachable.

[@MorleyKert]

Is the only difference between a strip sander and belt grinder the type of belt?

[@NikolajLepka]

Your woodworking projects never cease to amaze Good work!

[@jonwilson7555]

I really like the projects you do... thanks. What is your background in, you seem to have a lot of acquired knowledge.

[@OrionFyre]

3:07 I love how the angry pixie smoke is still present on your fingers :p

[@CreatureDesign]

I love your creativity, resourcefulness and ingenuity - but please be more careful! Especially when working with electricity! Who is going to post these videos if you fry yourself? ;-)

[@squidboy0769]

Matthias when the zombie apocalypse comes I want you on my team.

[@MichaelCoolidge]

I really liked watching and hearing your "problems solving" moments where you defined your problem and then set about solving it.

[@Meticularius]

6/4/2019 USA Grandpa Bill: Oh man! did you hear that? He was talking to the Martians at 5:28--5:29. THAT'S!! where he has been getting his superior knowledge, insight, and inspiration. Whew, a freak accident let us in on it. Well, at least he is charmingly human. My wife, Grandma Pat, thinks Matthias is just plain cute when he looks into the camera and says; "Oops!" (another video). He's captured her heart as much as he has captured my respect.

[@luciojosemariagraham3884]

Matthaias.. muy buenos los videos...sos muy claro y didactico al comentarlos... yo aperndo mucho de ellos . Te pido disculpes por no contestar en ingles soy muy duro para escribir en INGLES ... Gracias por tu aporte a mi ignorancia en un tema tan placentero como trabajar con madera. Lucho.

[@IanTheWoodchuck]

It's never an official WandelTool until it gets a coat of Wandel Green! You need to trademark that color like UPS trademarked UPS Brown.

[@giannislymperopoylos5574]

THE COLOR IS THE UGLIEST POSSIBLE ....PERHAPS MAKE IT LOOK LIKE A PROXXON SERIES.....BUT YOU ARE SO CREATIVE AND YOUR IDEAS ARE SO COMPLICATED IN A GOOD WAY....!!!

[@leifhietala8074]

@3:07 scorch mark on finger. When I'm wiring up a homebrew, I plug it into a plug strip with an off switch and its own breaker.

[@Beakerzor]

14:41 nailed it!

[@jo31b]

Beakerzor this deserves far more thumbs ups.

[@BOCraftsman]

Is it just me or is this the first “thumbnail editing” you have done for one of your videos? Btw, I always look forward to Friday’s to watch your latest endeavor !

[@papirojl]

You must really like avocado. Because to the color you choose for your tools...😂😂😂😂 Congratulation from Brazil!

[@glenpaul3606]

How much of that horrid green paint do you have? There are many nicer colors...even greens....lol

[@LarsSveen]

Your resourcefulness never ceases to amaze me, Matthias.

[@5iwot5]

You have a real talent of knowing what footage is boring or interesting to us. Not a lot of people on this site have that talent. It keeps me and many others entertained even after having watched you for a couple of years now. Just wanted to tell you that. Keep it up Matt!!

[@ericpeck3180]

You should put together a video of all your little accidents of things flying apart or exploding

[@ZoniesCoasters]

3:02 what is this? an electroBOOM video?

[@Sludgepump]

It's so good to see build videos from you once again, Matthias! Really enjoyed this one. MORE, MORE!! ;)

[@Remaggib]

Man, what I wouldn't give to be able to meet, hang out, and build with Matthias. Definitely one of the greats in terms of engineering, in my opinion. Get Matthias in a room with Elon Musk and we will send a fully operational robotically controlled wood shop to Mars before long

[@oscarhillier]

"I'm a little nervous to plug this in" *SPARK*

[@VanDerLaars]

No video today?

[@crazethedave]

I have a 2x48 sander and i use it all the time. You will be surprised how useful it is for all kinds of stuff.

[@bobkeller8383]

What is the deal with that green paint? Does it look different in person than on video?

[@greenatom]

I couldn't help laughing at the Wile E. Coyoted finger! Perfect comedic timing.

[@qiaoyanzheng1262]

greenatom I

[@DoitselfInfo]

This drive looks compact compared to the belt drive, but what about the vibration of the machine when the connection is misaligned? Is this happens?

[@jafarsidik180]

Video this week?

[@matthiaswandel]

No video this week

[@icew0rm]

Matthias Wandel glad you're still alive... I was worried.

[@JDeWittDIY]

I second the others, we're glad you're alive!

[@iainportalupi]

I noticed the yoke housing was shaped like an impeller housing and that got me thinking could you redo the yoke to be a small impeller and get the sander to be its own dust collector?

[@remijio303]

Iain Portalupi I was just about to say the same thing

[@marcoschwanenberger3127]

It will loose some power, but with a powerful enough motor it would definetly work!

[@chartle1]

But it would probably need a fair amount of power to push all the dust out the back in into one of his filters.

[@DMSparky]

Iain Portalupi I thought that's what he did?

[@chartle1]

Just rewatched that section and I didn't here any mention of it acting like an impeller.

[@peterjoy931]

How did you decide on the color green for you machines?

[@Etna.]

Hi Matthias! I have an old GDR made belt grinder attachment for drilling machines I wanted to convert. Watching your video has shown me what to worry about and what not. Thank you very much for showing your knowledge on that toppic! Keep up your great work! A great woodworker has no need for fancy tools. Regards, Etna.

[@mwalinchus]

Matthias, you are the MacGyver of KZbin! haha

[@robertoqueipo9535]

Lo mejor del vídeo la cara q pones en el minuto 3,5 menudo cortocircuito lo siento pero se me escapó la risa del susto, como te quedó el dedo negro. Y lo de no cortarlo para q veamos q hay q tener mucha precaución siempre. ,👏👏👏👏👏👏👏👏👍👍👍👍👍👏👏👏👏👏

[@RicardoGarcia-nn5nn]

voy a estudiar ingles para enternte ..pero se que eres un genio

[@DoItProjects]

You never cease to amaze me. Your innovation is unparalleled. We've been waiting for this video eagerly after catching all the fun on your Instagram feed. Mehdi at ElectroBOOM would be proud :)

[@chrisgray1158]

Very nice piece of work all the way. I love the way that you have over come adjustment's and so on. Nothing to complicated The whole completed job looks good. You know the saying if it looks right then it probably will be good. Look forward to more of your projects. All the best from across the pond UK Chris Gray.

[@maff3]

Anyone else watching just to see the green paint time?

[@CrucialMuzic]

Next project: *How to build a house out of wood.*

[@obi-wankenobi9871]

Is that even possible?

[@CrucialMuzic]

Of course! You just put Matthias and Primitive Technology together, and you'll have it done :)

[@eltallerdeelberg....1273]

Great build!! Hope one day you start welding and combine that with your woodworking skills!!! You could save the world!! Jajajajaja. A pleasure watching as always,congrats!!!

[@gmc07joe]

3:03 one of the greatest moments on your channel, only a "$#!t" reaction would have made it funnier! Thanks for the build. Nice machine. Be safe!

[@construction-productscemen4935]

Great job.

[@Nir.Arieli]

some people just have too much free time lol something for improvement: why not adding another belt next to it for the metal, so you won't need to change each time? the motor can spin both of them...

[@nickjm37fordel1]

I like projects you build on the go, you can see and correct flaws as you go :-) What color green do you use ?

[@kale.online]

Aw the green paint

[@BenMoeller]

Immediately "liked" this video at 3:00

[@amdomag]

I just love this guy..

[@JamesRPatrick]

The way you coupled the motor to the wheel is brilliant.

[@lapislignum]

This is looking great! i'm designing a belt grinder now, but it's going to be steel and be cut out with frikkin' laser beams. I'd make it out of wood but I don't have enough time or wood. and I don't want to make it out of wood.

[@GSMSfromFV]

03:08 __ The burn mark on the index finger is a nice touch!

[@bigpete4227]

GSMSfromFV Top marks for not trying to hide it though.

[@guitarslf132]

This could have been 5 parts if you didn't keep doing work off camera ;)

[@myprettyselena]

I guess it depends on why you're making this belt sander/grinder. Is it because you needed one or just the challenge of making one? I think for me I would buy one for $200 or so because my time is valuable to me. You did end up with a nice working tool but a bit Flintstoneish lol! I had fun watching you make it though and I'm now a subscriber. Now go build a wooden car. 😉

[@jeanpenus]

You should have your April fools day video this year be you just paining objects green. Like a full 15 minute video of you painting random things with nice close up shots of the paint being applied, after its applied. A couple of it drying.

[@rogertaylor712]

HI Mattias. Another great video. Are there any plans available for this grinder? Or even just a sketchup model. Thanks

[@Feralhyena]

A featherboard, or better yet, a pair of FeatherPRO FP1 inserts, mounted so that they slide against each other when you engage the motor, but mesh when you get kickback, might cut it down, and give you some vibration absorption.

[@bennyausdermuhle1173]

If you would give the clutch between Motor and belt pulley an impeller Design, it would work as a fan and suck out the dust off the grinder. So you would only need a Collection bag :-)

[@1969elder]

Didn’t see a comment but umm how’s your finger? Looks like a small electrical burn lol. Glad your still ticking my friend. And good job on the sander.

[@saltyd2137]

Man you come up with solutions so easily. Why do you paint everything green?? I think you told us way back but I forgot why.

[@akquicksilver]

You are certainly gifted with design on the fly skills!

[@SamfaidaMeRECREATOR]

Fai paura sei un genio, complimenti grande progetto, cercherò di copiarlo.. By Naples ITALY

[@HomeHaunter1]

Can you go over the wiring please? Not where you made Sparks, but where you added the high low switch. You have me stumped.

[@mkris8653]

I love to watch your mind work. There are no rules.

[@DanGamble]

Matthias, you're a mad, crazy, beautiful genius.

[@Bjornarp]

i shouldn't have one of those. I'd just use up all my metal screws and parts standing there grinding stuff away :-P

[@38911bytefree]

Have you considered making the impeler disc behind the universal joint thing so that the motor that runs the pulley also takes the dust out ... or you need more RPMs ?.

[@russterman1]

Nice one mate, good to see you back as your old "Mad Professor" self, making shit up as you go along. Top bloke :-)

[@jjforeal2]

Would it cut down on the vibration if you made your clutch plate round instead of oblong?

[@pstrap1311]

Cool. But you are issued an official safety nazi warning for operating those dangling switches with exposed live wires.

[@TheBobimkd123]

He is like a mad scientist, good thing he isnt a chemist :D love the videos

[@sventistvan9442]

I like the shirt cuffs...nice and loose..great safety......but on the whole makes me want to make upon a unit like this. thanks M

[@Moeller64]

You are a genius Matthias. Amazing build!

[@kickpublishing]

You could use a twist pulley (figure of 8 belt) or pair of gears to reverse direction

[@returnosf5043]

It's 2am and I have absolutely no interest in woodwork whatsoever. However, this is also the best video I've watched for a while, so I will leave my like here and go to bed

[@Blobjonblob]

Mathias the mad scientist of woodworking.

[@LALXLSKC]

Dear Matthias, these washer motors are great but they are not designed to be dust protected in their main purpose. I think that the motor MUST be complete covered on top with a wooden sheet or grounded metal (but not too close to coil and its air gaps to avoid overheating) because contact with metal chips coming from the grinder inside it will be at least destructive.

[@kenbobjohnson6132]

Major blunder: Did not use ‘the grind never stops’ in the title. People everywhere devastated.

[@racinjayson76h98]

I am a few days late with my comment but I have to say I'm really hoping that sometime in the future you find a need for a drum thickness sander because I would love to see your take on the engineering end.

[@VariXx]

...and if you flip this switch you can sand at MAXIMUM SPEED!

[@PJSproductions97]

I bet he fed like 15 screws into that thing before deciding on the shots to include, probably because it was fun!

[@deadfreightwest5956]
