Pour water into the tub. Add washing-up liquid and mix. You will reduce the surface tension of the water. Dust and sparks will fall to the bottom. I use this method at work.
Yes, I agree it works fine. Also consider placing a fine mesh tray 3 or 4mmmesh just below water level to catch items and stop waves forming in the tray
Phil your sense of humor while quite dry is very funny! It's also quite refreshing to hear someone realize they aren't perfect and be humble. You have done an outstanding job on this grinder and should be exceptionally proud of your accomplishment!
I can't believe how good you are at coming up with a system that actually works this well. That hinges and doesn't have to be taken on and off and adjusted to switch angles. Great work!!
if the sheetmetal rattles or buzzes, you could slip some clear hose over the posts to dampen noise? Also an old natural hair paint brush (plastic paint brushes might melt?) would stop any more residual sparks from getting past the rollers
I think it buzzes a little but if there's one thing this machine isn't it's quiet.. You don't really notice it through the infernal noise that comes from the belt going around at over 100km/h
Yesterday I was building my 2x72 belt grinder and thinking your channel haven’t updated for a while. And here we are!!! Love your contacts and videos. Keep it up 👍 make more video.
Have you considered maybe an electromagnet that switches on/off at the same time as the grinder? Which could be further improved by adding a vacuum that turns on for like 5-10 seconds after shutting off the grinder so it can all be removed every time you finish grinding. That's the method of spark/dust collection/control that I've been most leaning toward on my own 2x72" grinder build
Good call on the enclosure for the VFD - metal dust is a common cause of death. I wouldn't worry about overheating, it looks like a big enough enclosure.
The moving guards are pretty sweet. I’d put a small tray of water under the table to stop sparks bouncing out of the enclosure. Added bonus of being able to cool parts if needed.
Tolles video!! Du kannst auch ein kleines gewelltes Blech (oder auch ein gekantetes) mit Neodym Magneten darunter als Eisenpartikelfalle nutzen. Einfach zu herstellen und sammelt viel ein. Super mach weiter so....
Very special work, very protective to the utmost, but the new addition of the spark guard has destroyed the splendor of the device with this addition. The simplest way was to get rid of sparks by placing a bowl of water at the bottom of the device in which the sparks would fall. However, you are a genius.
Please tell us Phil, a little bit about how you came to gain such skills. Machine school? Just hands on? Mentoring under past masters?.You set an incredible standard to follow which for this ‘greenie' seems nearly impossible. Your work and comments guide tool selection. Would love to build a similar grinder. Oh ya, mine works fine but would never get through the door were it being compared to yours, which I might add is almost too nice to use. (I said almost....LOL). Would love to build one with an eye toward yours but the time required is a huge factor and the one I have does work to my satisfaction even if it doesn’t remotely reflect your skills and talent..I best just admire what you do and press on. Keep up the outstanding work. Thanks for sharing.
I mostly taught myself by watching other TH-cam machinsts like ToT (I guess you could almost call this mentoring) and just learning by doing - and honestly I'm probably not as good at it as you might think ;) When I first watched machining videos I was also very impressed, but as with everything, once you start getting into it the fog starts to lift and things become more clear and things that formerly seemed impressive turn out not to be that complicated after all. I'd say it's mostly about patience, curiosity and taking the time to get some experience, but not a skill you need some kind of amazing talent for. I'd say almost everyone can learn the machining required to make this grinder relatively quickly - it's mostly just relatively basic operations, nothing super fancy. It's a big volume of work due to the sheer amount of parts and operations, but the operations and parts themselves are rarely complex (for example almost everything has square sides). There's only a few spot where you need to hit tight tolerances, and since everything is in individual small parts, if you mess one up, you can just start over with that part, which is what I like about the design - it lends itself to a "part by part" approach, which is how large complicated things are simplified - just taking it one piece at a time. If you make one part every weekend, you could be done in a year 😅 So if you have the equipment I'm sure you could make this if you take your time, but time you will need
Hi, very well and cleverly done. A real pleasure to see. Moreover for T-slots on the grinding table and his system of positioning, etc. Bravo ! For collecting dust, maybe I should add that collecting the maximum quantity of dust, just below the bottom front wheel, at the "source" of them, would alleviate the need of making a "full" chassis all around the sanding belt. I've seen buckets or big pipes (200 mm diameter may suffice) fulled with water and also vacuum air pipes, horizontally positioned at the "source" of dust. Last, I'll add some weight or another system (another clamps ?) for avoiding the sander to move if you push too much hard against him. Cheers from Marseille, France
Haaa! Knowing the series, I read the comments first before watching the video. I came across this one, and thought ‘hmmm’. Then I watched the video and heard him ... 😂😂😂😂
This entire machine, core build, spark arrestor and all, is hands-down one of the BEST 2x72 belt grinders I have come across on TH-cam or otherwise.... I realize you don't know me, but coning from me, that's quite compliment, seriously. I more or less consider myself to be connoisseur of finely built belt grinders, if you will... I have also built more than a few bulletproof builds myself and if you look at my TH-cam profile you'll see that I have put together a few very extensive Playlists of all my favorite grinder builds on TH-cam... point being, this is a magnificent build, Jeremy Schit and Brian House may both make excellent grinders, but they ain't got "Schidt" on your build (see what I did there? Haha)... for real tho man, awesome build and awesome content, keep it up my friend! Cheers! - Jesse
I have found when grinding welds down to look clean and uniform it works best to do soft and even strokes along the length of the weld. Slowly feather the weld into shape. It's a slower process but looks great and you don't get grinder marks in unwanted places
I love this belt grinder. I wish I had a mill so I can build it. You ever think of modifying/adding a brush to the shield? This way it should stop most of the debris from flowing around. Something like a a welding brush 1mm off of the belt should help a lot
Very nice solution indeed. Honestly what little left going out is not going to cause issue, assuming wear usual safety stuff. Plus amount that do get out is small so it takes a while to need cleanup outside of bin.
Great idea. Beautiful workmanship. My observation is that some of the dust/sparks is getting recycled because it hits the bottom of your pan and reflects back upward into the belt. If there was a collection tube under the platten that might create add to the effectiveness. Thanks again for the great idea and setting the standard.
Interestingly, it actually helps to not clean the pan - after a short time, a pile of swarf starts to form under the platen, which seems to do a good job of "catching" and extinguishing further sparks. The dust actually gets so condensed you can just pick it up as one piece after some time and throw it in the trash. Overall I'm still quite happy with this about a year later - the dust that escapes is minimal, the only thing that would still be a big help is an air filter in close proximity, to clean the super-fine dust that floats away in the air and gets into your lungs
Wait!!! You're one of those weirdos that wears pants in your shop? Love your content and the dialogue that goes with. Thanks for your time and effort, it's greatly appreciated.
if you take your bottom guard and instead of having it bend to follow the belt path, you have it direct the sparks to the left of the belt it will direct the sparks down when in horizontal mode. Then (if necessary) put a turn down deflector mounted to your pan so that when the sparks are getting ejected to the left, it catches those sparks and then puts them towards the base pan. if you want a very effective "spark arrestor" (to slow them down so that they do not bounce off the bottom then you can build a chute with a series of crecent deflectors in in (sections of tubing) that will force the sparks to fall out of their air stream and hit the walls (with several re-directs). This will cause them to loose enough energy to fall out. (very common form of dust filtration) Stuff Made Here (on YT) made a large format one for his plasma cutting table to handle the sparks and dust it generates.
Try folding longitude lips of about 20mm to each side of the guides. I believe that this will block the glancing sparks tha hit the flat surface and then rickosha off at an angle. Great work and fine machining.
*What I noticed with your grinding was that the sparks hit the table, and the ricocheting was causing all your problems.* *Move your grinder forward of the table edge, so that the sparks are directed to the floor, and secure the area for safe operation.* *Otherwise; installing a small removable water trough below the table edge (8x3x3 & fill 1") would extinguish sparks, and catch most of your debris.*
Really implemented! Try to put a piece of rock wool (insulating material) under the support table. That would dampen the impact of the sparks a little and prevent the ricochets for the most part. Greetings from Styria
9/1. Take a aluminum bottle with cap, place magnet in bottle. Place in pan , most grinding will be on bottle n simple tap on edge of waist can n they will be off.
Love your videos. Quality stuff. Grinding, drilling, bandsawing with gloves on, though... just freaks me out. I know, safety people would argue the other way, but I had a T-shirt sucked in a grinder, probably by the airflow, not even contact, and it happens in milliseconds. Also had this assembly type glove rolled up by a cordless drill. Not fun. By the time you let off the trigger, it's long done. Fabric based or woven type gloves can have the thread caught and pulled by the slightest roughness, everyone experienced that, the rubberized grippiness doesn't help either. So maybe real leather, or preferably none.
Great video and workmanship on both you tray and grinder. What I did to stop the sparks traveling around with the belt, was to fit a guard at the bottom of the belt. It would be positioned 90 degrees to the belt just behind the front leg of your grinder and about 2mm lower than the belt. This has stopped the vast majority of the spark travel.
It would be a god awful mess to clean, but I have seen others add a fine spray of water to the belt at the tension pulley. And would be pretty much worthless in horizontal mode. It is also suppose to add life to the belt because it runs cooler. I chose to have a dirty and clean rooms in the shop. I do like how you solved the moving top shield. Innovative is the word.
Yeah a seperate room for grinding is definitely the best move if you can accomodate that. You can only reduce the mess these machines make but never get rid of it 100%. Don't get me started on angle grinders...
@@PhilVandelay My shop is a 24x36, I partitioned off a 12x24 in the back as the clean room. The 24x24 gives me plenty of room for metal working and fixing vehicles. Due to health reasons it's been a long time getting there, but the clean side and all it's benches are about done.
In the vertical configuration it looks like about half of what ends up out of the pan is due to bouncing off the bottom of the pan. You might be able to reduce that by filling the bottom of the pan with a thin layer of oil or water. Flowing liquid to carry away the dust would be far more likely to work in addition to other advantages, but is also an order of magnitude more complicated to build.
Yeah I considered that and I think the pan is watertight, but I'm not sure I want to deal with the disgusting/toxic sludge that would build up in there. You'd probably have to take the grinder out and rinse the whole thing to clean it. I suppose you could put a drain valve somewhere though and use a hose, but overall it's still a messy process
My first frequency variator, I had the idea to clean it with air from the compressor. First and last time. Something exploted immediately when I plugged it again. For sure a short circuit of metal powder
Hello Phil Nice work. Place som watertrought under the lower frontwheel it will kill the sparks and collect a lot of the dust and is easy to take away and clean with water. Remove the lower sheld
Loverly. Did you consider some kind of brush mounted so it just skims the belt? May be able to minimise the escaping sideways-sparks by widening the last deflector a bit? I do envy your workspace.
I appreciate the work you did putting this together and sharing. You inspired me to rip the wheel fender off of my boat trailer and use it, since it’s almost the same thing. (Haha kidding)
beautiful ... but alas, a slightly wrong approach, the abrasive must be taken away from the tape and not run around it in a circle! I recommend collecting the first vertical stream with a funnel in a container, as a rule, the most common collection is a bucket of water, since water collects scales well ... the second horizontal funnel with an exhaust hood where you can use a vacuum cleaner or an exhaust system through the wall to the street and into the container
Instead of spoiling the aluminum sheet, it is better to put a container of water or coolant under the shelf and the bottom roller. Greetings from Poland
I used the same basic idea for my radial arm saw; it's a bit bigger and it's hooked up to my dust collection system; works great. If it were me I'd of let the sparks continue down into a funneled opening, and add a short plexiglass shield to the right side. jmo Still it's good though; *well done.*
Phil, have you considered using a wet tray, I have used a scotch pad in a tray with water and fill it to just before it covers the scotch pad and that has worked for me to eliminating most of the bouncing sparks.
I did consider it, and I think you could even fill the bottom of this pan with water since it should be watertight. The reason I didn't do it is mostly that I'd dread cleaning out that sludge in there.. but the scotch pad is actually a good idea, that way you can just wash the pad instead of scraping everything out of the pan I suppose
It seems like you may want to run the cables that are coming through the back leg through the bottom of the dust collection pan so they don't get slowly eaten away by grinding dust
Great video, what about let the belt pass through a plate perpendicular to the belt and with a cut just a little bit thicker so that you can change the belt but at the same time it act as a wall for the dust particles
I'm wondering if a compressor to blow off the sparks would be a better method. I'm thinking of the small ones used for laser engraver/cutters. This might blow the spark off the belt and help burn it out faster. Placed at the second cover it should remove the stuff before it goes any further. More like an air curtain as used on doors, rather than a vacuum or mechanical shield.
Ooo, ooo… what you should do is completely enclose the grinder in a quick remove shield! Ya know, those things that many other grinders come with… and are the FIRST THING people remove! LOL! Safety glasses, gloves & body apron. That’s what they were made for. Besides that, thee we bucket of water is still the best.
Suggestion for the shields. I thought about this a bit, but why not put side walls on the shields that surround the belt too, rather than just top dead center like you have. They would be similar to the design of the tub you built below to catch the majority of the metal dust. The shields original design can still remain hinged, just put a side wall angled at 20 degrees on either side to catch the sparks that wonder off the edges of the belt, deflecting them downward into the pan. You wouldn't have to weld those sidewalls in, just use some of that thin aluminum bend to 110 degrees, and just drill and rivet them to the shields you already have. Less hassle that way I would think, but welding them would just make them look prettier is all. I also thought that you should pull your working table a bit further away from the belt, might also help mitigate a lot of those sparks from bouncing off the table and hitting the person using the grinder, like maybe about no further than 13mm away from the belt on the edge of the working surface facing the belt.
Side walls would work, but they get in the way of changing belts. It is particularly annoying when you're working through several grits and changing belts all the time.
Maybe you have to separate the pan in two sections ... 1st with 5 mm water to catch the Sparks and the 2nd without water . In my opinion that Would help more ...
Awesome upgrade! I wonder if it's worth removing the deflector plate underneath the table? It seems this is funneling a lot of sparks along the belt path and back around. Perhaps adding some water to the pan would help contain the side sparks... or maybe a damp cloth if you don't fancy sharing your workshop with swamp animals after a few weeks 😁
@@PhilVandelay Can you please remove deflector plate underneath the table and use some kind of pan with water instead ? Please make a video of difference. Thank you.
I love your content its absolutely amazing I just have not enough of it :D. You should consider to doo some time laps how you edit your creations in the program. Also what program do you use ?

My first frequency variator, I had the idea to clean it with air from the compressor. First and last time. Something exploted immediately when I plugged it again. For sure a short circuit of metal powder
Hello Phil
Nice work.
Place som watertrought under the lower frontwheel it will kill the sparks and collect a lot of the dust and is easy to take away and clean with water.
Remove the lower sheld
Metal sponges from kitchen working very well for catching sparks.
Phil, great series. Great work. Great project. Keep it coming!
Loverly. Did you consider some kind of brush mounted so it just skims the belt?
May be able to minimise the escaping sideways-sparks by widening the last deflector a bit?
I do envy your workspace.
Nice fix to a complicated problem. Thanks
I appreciate the work you did putting this together and sharing. You inspired me to rip the wheel fender off of my boat trailer and use it, since it’s almost the same thing. (Haha kidding)
Just finished watching the original trilogy hahaha, I look in the recommended videos and this shows up, nice haha
beautiful ... but alas, a slightly wrong approach, the abrasive must be taken away from the tape and not run around it in a circle! I recommend collecting the first vertical stream with a funnel in a container, as a rule, the most common collection is a bucket of water, since water collects scales well ... the second horizontal funnel with an exhaust hood where you can use a vacuum cleaner or an exhaust system through the wall to the street and into the container
Very inspiring videos.Thanks for sharing.
But it seems that your budget for tools ,machines , materials ... as well as free time is nearly unlimited.
Nice Job Phil very neat and effective
Instead of spoiling the aluminum sheet, it is better to put a container of water or coolant under the shelf and the bottom roller. Greetings from Poland
great video. Thanks for sharing. Regards from Florence (ps: I have copied your tips for making the lathe stiffer...wow...thanks it worked)
I used the same basic idea for my radial arm saw; it's a bit bigger and it's hooked up to my dust collection system; works great.
If it were me I'd of let the sparks continue down into a funneled opening, and add a short plexiglass shield to the right side. jmo
Still it's good though; *well done.*
Phil, have you considered using a wet tray, I have used a scotch pad in a tray with water and fill it to just before it covers the scotch pad and that has worked for me to eliminating most of the bouncing sparks.
I did consider it, and I think you could even fill the bottom of this pan with water since it should be watertight. The reason I didn't do it is mostly that I'd dread cleaning out that sludge in there.. but the scotch pad is actually a good idea, that way you can just wash the pad instead of scraping everything out of the pan I suppose
Hehe drilled into the shaft... 😁
Well you no longer need that Nylock nut on that shaft... 👍
It seems like you may want to run the cables that are coming through the back leg through the bottom of the dust collection pan so they don't get slowly eaten away by grinding dust
Did you consider installing a removable powerful magnet in the bottom dusk container to catch and stop the bigger sparks?
Magnets help, I added some to my drill sharpener it catches most of the sparks.
Nice idea brother
Great video, what about let the belt pass through a plate perpendicular to the belt and with a cut just a little bit thicker so that you can change the belt but at the same time it act as a wall for the dust particles
I'm wondering if a compressor to blow off the sparks would be a better method.
I'm thinking of the small ones used for laser engraver/cutters. This might blow the spark off the belt and help burn it out faster. Placed at the second cover it should remove the stuff before it goes any further.
More like an air curtain as used on doors, rather than a vacuum or mechanical shield.
Great discover and ultimate idea,95% of dust gone👍
Great job!
Shame that i have no much space for machines in my rooms corner.
You nailed it, great job!
Keep the bottom shield removed and place a water bath below the belt to catch the bulk of the sparks. It will be 90% cleaner.
Ooo, ooo… what you should do is completely enclose the grinder in a quick remove shield! Ya know, those things that many other grinders come with… and are the FIRST THING people remove! LOL! Safety glasses, gloves & body apron. That’s what they were made for. Besides that, thee we bucket of water is still the best.
Suggestion for the shields. I thought about this a bit, but why not put side walls on the shields that surround the belt too, rather than just top dead center like you have. They would be similar to the design of the tub you built below to catch the majority of the metal dust. The shields original design can still remain hinged, just put a side wall angled at 20 degrees on either side to catch the sparks that wonder off the edges of the belt, deflecting them downward into the pan. You wouldn't have to weld those sidewalls in, just use some of that thin aluminum bend to 110 degrees, and just drill and rivet them to the shields you already have. Less hassle that way I would think, but welding them would just make them look prettier is all.
I also thought that you should pull your working table a bit further away from the belt, might also help mitigate a lot of those sparks from bouncing off the table and hitting the person using the grinder, like maybe about no further than 13mm away from the belt on the edge of the working surface facing the belt.
Side walls would work, but they get in the way of changing belts. It is particularly annoying when you're working through several grits and changing belts all the time.
этот гриндер самый крутой что я увидел здесь на ютубе. молодец.
Very well done -as always ✅👍
Well done kind Sir.
very good as always👌👏👏👏
you need a tray of water below the first roller that does the grinding. this will eliminate 90% of the sparks that blow around the belts.
Maybe you have to separate the pan in two sections ... 1st with 5 mm water to catch the Sparks and the 2nd without water . In my opinion that Would help more ...
Hola
Para parar las chispas
Podés poner un recipiente con agua
Proba cuando trabajes con la máquina vertical
Awesome upgrade! I wonder if it's worth removing the deflector plate underneath the table? It seems this is funneling a lot of sparks along the belt path and back around. Perhaps adding some water to the pan would help contain the side sparks... or maybe a damp cloth if you don't fancy sharing your workshop with swamp animals after a few weeks 😁
Yeah it's definitely better to remove the bottom deflector for vertical mode
@@PhilVandelay Can you please remove deflector plate underneath the table and use some kind of pan with water instead ? Please make a video of difference. Thank you.
Excellent design!
Just thinking maybe add a type of brush to front lower shield see if any better ........... maybe😊
I love your content its absolutely amazing I just have not enough of it :D. You should consider to doo some time laps how you edit your creations in the program. Also what program do you use ?
