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.
This is probably my favorite grinder on CZcams. Masterfully built and perfectly thought out. Very nice work on it!
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!!
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.
Beautiful work. Your attention to detail is unbelievable
That's nice work, nice to see some attention to detail with the shield supports.
Always a pleasure to see you work
Hallo Phil. I am a great admirer of your work. Seems like you are very systematic in your approach mostly in your projects.
A nice addition to a well thought out, well machined, superior tool.
Ahh, the old safety squint! I used to use this amazing piece of safety equipment until a cutting disk disintegrated on me!
Phil, great series. Great work. Great project. Keep it coming!
Another well-thought solution for the dust and spark problems on your belt grinder machine. Nice work Phil
Like the use of rivets. Very elegant. Also that axis-anti-rotation mechanizm is cool.
This is truly a work of art 😍
Phil, I enjoyed watching the process of solving your spark problem. I'll want to do this when I finish my build of the belt sander.
Really enjoy your videos and hearing your thoughts, processes and procedures in proble solving.
Gute Ideen und klasse umgesetzt. Bist doch gut duchgekommen und alles funktioniert. Einwandfrei.
Nice job man I'm surprised you were able to do all that and still make it look good....great video as always
You nailed it, great job!
16:25 - it also means that if someone buys this and copies it for resale, all copies will have that "hole" in the pin.
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.
Very well done -as always ✅👍
So much fun watching your videos
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
Interesting solution. Thanks for the video.
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
Respect, Phil Vandelay!
I wanted to make a belt Grinder myself your design gave me a lot of great Ideas
Nice Job Phil very neat and effective
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.
Very cool! I love that anti-rotation element on the axel at 16:03 very clever :)
That's one way to put it 😅
Excellent design!
Excellent solution!
Congratulations for your 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
very good as always👌👏👏👏
yeah! great improvements!
Well done!
Nice fix to a complicated problem. Thanks
Great job 👍🛠️
Well done kind Sir.
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....
It's really amazing
Great work
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)
nice work !
Totally awesome, you're a great machinest
I'm learning a lot from you,
Thanks
Rolf from USA 👍
Just finished watching the original trilogy hahaha, I look in the recommended videos and this shows up, nice haha
Love your work! Wish I had a grinder like that
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
You "usually" wear pants in the shop? I've gotta try that sometime.
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 ... 😂😂😂😂
great video. Thanks for sharing. Regards from Florence (ps: I have copied your tips for making the lathe stiffer...wow...thanks it worked)
Could also try adding an electromagnet near the bottom where most of the sparks go, would make for an easy clean-up too! :)
nice work
Nice idea brother
Buenos dias , muchas gracias por tan buenas sugerencias, excelente calidad en los proyectos que realizan.
yo compré los planos del Belt Grinder, y ya tengo terminada la maquina.
Donde puedo comprar la Grinding Belt, preferible en USAMuchas gracias !!!
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.
Looks like a good solution, I was going to try some brushes as I've not seen that before.
Had you given any thought Phil of fabricating a clear plastic cover for the top and sides and hinged so you could lift it out of the way as required?
Awesome skill
great job thanks!!
Nice job
On lorry’s they use a special rubber anti spray guard for wet conditions ,maybe something along those lines would help.
This entire machine, core build, spark arrestor and all, is hands-down one of the BEST 2x72 belt grinders I have come across on CZcams 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 CZcams profile you'll see that I have put together a few very extensive Playlists of all my favorite grinder builds on CZcams... 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!

Great discover and ultimate idea,95% of dust gone👍
Very worthy!
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.
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
very good!
Great video man...thanks for sharing..;-)
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
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.
Well, that is much simpler than my solution! I'll have to try this out when I'm in the shop
@@PhilVandelay I think yours will look much better than mine.
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
Phil, What did the wise man once said ? If you can't make it perfect, make it adjustable !! 🤣
Great job!
Shame that i have no much space for machines in my rooms corner.
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
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.*
Still, by far the nicest belt grinder on CZcams maybe even the world!!!
💪🏼💪🏼👍🏻🤣🤣
Check Jeremy Schmid's chamnel, he built the ultimate belt grinder, just before this video came out
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
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 CZcams 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
Metalist’s are such perfectionists. Manufacture and sell these. I would buy one.
How abou putting some of those dust sweeps ( the ones that like like small brooms) at the back dust shield. It would allow the belt to pass freely but should catch all the particles
I wonder if some strong magnets on the end of the guard would make any difference??
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.
Would a rubber wheel on the outside (grit side) of the belt interfere with operation? Would it prevent the dust from running along the belt?
can you tell me yours setting for aluminium welding on tig ac?
Metal sponges from kitchen working very well for catching sparks.
Great job. Just a thought but did you consider installing magnetic material to catch ferrous material?
I am building two of these..are there plans for a wheel accy. to replace platen?
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 ?
I love it
Ha, you usually wear pants in the shop. Yes I think it’s optional too 👍
Great video!
How the Heck did Jeremy Schmidt and you do the SAME video in two days lol
I was thinking the same. Two of the best builds share add-ons within two days. 😂
I swear this wasn't planned 😅 But with the frequency of our uploads it's definitely a very unlikely coincidence
Love your grander! Do you sell it or just drawings?
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.
*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.*
What if you use a Electromagnetic shield that collects all "iron dust" or most of it and then dissengage it to clear it? would be nice improvement
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
Nice 👍
Would some kind of thin brush barely touching the bottom of the drive wheel help distract the Klingons?
