- A scenic stroll through the build of a useful tool for any TIG welder.
Gas Tungsten Arc Welding (GTAW) or TIG Welding works best with a carefully prepared tungsten electrode. A dedicated diamond tungsten grinder is the best way to get a perfectly prepped TIG tungsten electrode angle. Most of these grinders are expensive, so this DIY diamond tungsten sharpener is a must have for the shop.

You can learn to weld. I'll show you exactly what to do in my affordable online welding courses at courses.timwelds.com.
Bought it today--working my way through fab 101
I just built one based off your design. I did add a continuous rim 4.5” diamond wheel to cut the tungsten. I also built my frame slightly different. I used the handle hole to bolt to. Thanks for the video
Any photos you can show please.
Tim, that thing is genius, and I've been TIG welding for 25+ years. Keep up the good work. 👍
Thanks 👍
Great great idea, only one thing I'd change is to flip the guard to the opposite side just in case you have a finger slip for some reason.
absolute fantastic tip! thanks. Much better than many $200 plus priced machines
Great job, why pay hundreds or I should say why do they expect us to pay hundreds? I think you did a great job proving we are smarter than that. Thank you.
Totally! They are surprisingly expensive.
Great idea. For anyone who wants quick results, you can drill a hole in the existing shroud, and cable tie it to a 2x4.
Great idea.
Hey Tim; This is so clever. I built one for myself. A couple of things for the next guy to consider. 1. The geometry of the height of the disk to the welded screw is actually quite important. You may want to get your disk all set up with whatever spacers etc. you will be using prior to locating your screw. The guard is flimsy enough that you can bend it some to adjust the height of the angle iron if it isn't working out for you. 2. I added a more complete guard. I butt welded a half round bottom to complete the guard and enclosed all of the sides but about an inch where the angle iron drops in. I was very uncomfortable with that spinning disk exposed and me working on the business end. 3. The disk actually ends up piloting on the threaded portion of the shaft which is a very sloppy fit. It takes a little tweaking to center the disk prior to tightening it down. 4. As a result of the sloppy pilot, I am considering using a step drill and punching out the center of the disk to 5/8". Then I could use the correct pilot on the parts that came with the grinder. This would, of course upset the screw to disk height geometry and may even wreck the disk, so I'll hold off on that until the disk is well worn and see what happens.
Thanks again for this clever idea. I really like it. I often use it with a cordless drill to hold/spin the tungsten. Do you see any downside to that?
Magnifique,ingénieux et très peu coutant .Bravo à vous et merci
Your videos are absolutely helpful! Appreciate your time putting all these together. Thank you!
Hey Tim, cool little grinder. I think this will be my weekend project. I just started to learn how to tig and sharpening my tungsten on the harbor freight 8" grinder probably isn't the best way to get a consistent point. Thanks for the video.
Thanks for a great video. I just finished building it and ground 20 electrodes in about 5 minutes. I did have to change the guide to the opposite side because the wheel kept sucking the electrode into it. The only other issue was that the hole was drilled oversized in the disk from Amazon (no surprise).
hey man you best get a pattern on it before i do. Its a excellent work of ingenuity. I am on my way to the pattern office.
Good job Tim
What a great idea!! I intend to make one soon. I think I might make the leg of the angle with the holes for the tungsten longer so that I can adjust it to take advantage of the entire surface of the diamond wheel. Thanks for this build.
Thanks Tim. I'll make one this weekend !
Excellent idea! Thanks so much!
This is a great and really functional build. Nicely done. I have been using a diamond lapidary wheel outboard of an 8" grinding wheel on a bench grinder for over 15 years now to grind tungsten. That cost about 40 bucks and i hold my tungsten with a drill. I might just have to make myself one of these ! Maybe as a part 2 you can come up with an enclosed version to collect the dust.
instaBlaster.
Where can I order that diamond wheel? I think I’m going to build this but on my bench grinder.
I used to get them off ebay buty rings a bell for the seller. Can't remember exactly since I've had them so long
It called a diamond lapidary wheel
Brilliant build Tim...so glad that I have found your channel...more useful information here than most welding sites combined!
Thanks!
Thats a great idea! You just saved me a $100, so glad a tuned in.👨🏭
Thanks man!
Thanks again Tim...love this channel!!
Man that is fantastic! As soon as I’m done with my game I’m watching , I’m heading to the garage. Thanks for the spark that lit this flame🙌🏻
Thanks! It really does work quite well.
Both of y’all need to move the hell on. Your garbage comment has nothing to do with this video.
Just ordered a TIG today and saw that a proper grinder was $70+ so I'll certainly be going this route. Thank you for the video, subscribed.
the ones I have seen were $700
Great job. Thank you for all your videos.
THANKS so much, Tim!
Things really change in 3 years since you made this video (99 cent paint - Ha) but this idea is still a real money saver, while giving a very professional result - So excited to make this - and save some Buck$!
Oh wow. I didn’t know we had to grind TIG electrodes. I’m still in the SMAW rabbit hole.
I have some aluminum piled up but no real projects-maybe I’ll stick around a bit down here. (No pun intended-it just happened 😀)
And thanks for posting!
Brilliant, I was using my dremel with a small 1"Harbor Freight diamond cutoff wheel, works great but I like the idea of getting the same angle every time.
Im going to build it
Thanks for the movie
The 400 grit works nice. Thank you sir!!!
great video! thanks for uploading
Great build! Thank you for the ideas!
Thanks! It was a fun one!
Thank you Tim, make it and works great!
Love the video keep up the great work Tim
Brilliant! Love your vids brotha!
You deserve 25 million subscribers.
Great idea.
This same setup can be expanded to sharpen drill bits as well.
Brilliant idea, I wish I could give it more than one like.
hi mate, nice project, thanks for sharing!!!
Great idea and great job love it
In HVAC, I had to tig stainless ducts for a job. Bought dewalt's new cutoff tool and used this same method to conveniently sharpen tungsten while on the ladder.
Nice build. I am using a little adapter with a diamond disc on my dremel, but this looks much more substantial.
Good job!
Interesting project, appreciate your video.
Thank you too!
Amazing. Better then the crappy 20$ one I jus sent back to amazon. Thank you very much. Nice thinking. Very help when your welding on a budget. 😂
I’m going to build one ASAP!
Sweet! It's a useful little guy so far.
That is super awesome. I’ve seen the rotary tool ones, but it seemed to me something based on a die grinder or angle grinder would be the ticket.
Thanks great idea😎
Very good tools!!!!!!!
Nice project. I have been hand holding a portable drill with the tungsten in the chuck against a dedicated bench grinderl. I do like the idea of a diamond wheel. Thank you for posting the links. You got me to thinking about making a fixture for the el cheapo bench grinder from the 60s (5" Edison) and adapting a diamond wheel to it.
Very cool! This one is still working great with the original wheel, and believe me, I have to sharpen my electrode pretty often. I'm thinking about making a second version with a fully enclosed wheel to make sure it contains the dust from grinding.
Have you thought of making a sliding one to “work the whole disk” that way one just doesn’t wear out just the edges of the disc
I like it. I would probably run a vacuum next to it, especially if any thorium was involved.
I agree. I have a version 2 on my to do list to enclose the wheel and capture the dust. I don’t use red thoriated tungsten any more because lanthanated and LaYZr work great and seem to split less often on AC.
@@TimWelds I plan on entirely copying your design. Thanks!
at work i've been using a harbor freight stationary belt sander with 60 grit (probably) aluminum oxide belt. easy to get a long taper and a needle sharp point, if that's what you're after. chuck the tungsten in a cordless drill and it saves burning your fingers, plus makes turning easy...don't know why you wouldn't if you can! obviously the drill works with any grinder for turning. i also have some diamond coated discs at home. 200 grit leaves a nice finish and it's not too slow at removing material IMHO
That was pretty good. The grinders are nine bucks right now and I’m thinking about grabbing maybe three just to have dedicated wheels on them at the bench - pretty much disposable at that price. Oddly the reviews indicate they actually last pretty well assuming you don’t ask too much of a 4 amp grinder.
I have an aluminum core Strauss “UDGW” 6” diamond wheel on one of my bench grinders that I use for tungstens - it will live a lot longer than me. Thanks God I didn’t have to pay for it. (helps to have friends in aerospace) 😎
Wow this is absolute awesome... Have you ever considered manufacturing and selling of this?
There must be a great potential out there!!
Greetings from Pete the Welding Warrior
you can buy tungsten wheel at habor f for 10 dollars but you have to re drill hole with a step drill works good hope it helps zimm
Is there a reason not to use the backing flange that is typically used under a grinding disc.
As opposed to using the machine bushing I'm not quite clear on why that was needed.
Thanks
The bore diameter is too small in the diamond disc.
I’m interested in your bench cut-off saw. Could you tell me where it can be purchased and brand etc,
Just found your channel an subscribed right away! Thanks!
I was using a little Dremel attachment thing to grind mine, but I hated it. Actually forked out a pretty penny and got a little machine made by MWL in Japan specifically for grinding tungstens. Maybe a little overpriced, but its very quiet and does a damn good job. I don't like loud tools lol... Great video!
Great design: Simple, functional and elegant. ...Happen to have the sisk and an extra grinder, so going to the shop and build one right now!
Thank you
Awesome build thanks for the tutorial. Just ordered my diamond wheel. Hope it's an affiliate link so you get a little something for your effort.
Awesome thank you!
What kind of chop saw is that? Nice jig for tungsten as well. Im going to have to make one
Great job. Awesome idea 💡 👏..
The saw u use in the video can you share a link where u purchased? Thanks.
What a great method, I'm going to get a (cheap) tig setup soon as I'm an engineer and determined to have this skill in my repertoire...I was thinking I could get away with putting my tungsten in a drill chuck and just hitting it with a diamond file while its spinning...do you think this would work?
Thanks for the video, I was planning this build and got an angle grinder from harbor freight unfortunately the diamond blade I got that was similar to yours is a 5/8 size arbor and the arbor on my grinder is 7/8. Putting the wheel without the arbor on the grinder fits but is too loose and won't stay centered. I was wondering how you got the wheel to fit. (I can't find an angle grinder to fit that size diamond wheel.
Nice idea Tim! What would you say you enjoy more..."engineering/designing" parts to be welded, OR hands-on Fabricating them yourself? Seems like both lol I'm def on the fab side. But THIS is an awesome idea, which I may have to take stock in. Thanks!
I enjoy the hands on most, especially when I'm kind of designing on the fly. Thanks!
Nice work. Which way is the disk turning where you are sharpening. Towards you or away from you?
That exposed disc makes me nervous, a whole way around guard would be a welcome upgrade.
Hello, good idea.
But i wonder what about the grinding dust that is released??? We are not talking about cotton candy here. I prefer a closed housing. After all it's my health . . .
What brand was that cold metal cutting saw? BTW. Nice job. I liked that you took the time to explain all of your steps as opposed to some of the other videos I’ve seen that basically run high speed video with no dialogue.
It's a Trajan from sawblade.com. I really like having a 7" chop saw for portability. I got it on sale for a good price and I use it regularly for small stuff. Here's a review video I made when I first got it: ruclips.net/video/etyj-_RpnSI/видео.html I think the Ironton from Northern is similar, though I've never tried that one.
Very nice. Can you explain why you used the machine bushing rather than just using the inner flange that came with the grinder, like you would for a cutting wheel? A commenter mentioned the bore size of the wheel, but that doesn't seem to make sense. Thanks!
2 COOL THX
Does the grain of the tungsten tip run parallel to the tungsten itself or is it so fine that it doesn't really matter?
How long did the diamond disc last? As it looks like it was wearing away already.
Nice and simple design! Since the tungsten will be grinding in the same spot on the diamond wheel, how long do you think the wheel will last? If the guide was adjustable up/down you could probably get a lot more mileage out of it. Maybe a V2 update if the wheel starts to get worn down or something. Thanks for sharing!
Thanks! I’ve been using it since the build, probably 50-80 grinds. The wheel still works like new, but it would be nice to have the option to move it around. On other diamond grinders that I have used, the wheels have lasted a really long time. The biggest problem I’ve seen is aluminum from a fouled electrode getting deposited on the wheel and clogging it up. Either way, I’m glad the wheels are $10 instead of the $90 that wheels for my fancy grinder. 😁
What is that chop saw you used!!!!
I tried this set up. But the tungsten gets too hot and has a blue gray hue after. Arc is very erratic. How are yours so clean. Different grinder but same disc. Same result for different brands.
Awesome build! Just a heads-up, tungsten dust.. it's cancerogen.
Hi. When you contaminate your tungsten, is it bad to just grind it back to a point? Can you contaminate a diamond stone?
great tool. Only issue is if you are still learning like me, and you contaminate your electrode , you can't get it out unless you remove your twist bolt and star washer. I have one of those dremel fixtures and it is the same way, and it slows down your work. I guess the only way to get around it, is to not contaminate your tungsten =/
THIS is my next project.
HF has a coupon for that grinder for $10
You're supposed to use the lower half of the nut on the grinder.
Just got my first tig and binge watching as much info as possible while I'm down sick. What about tip grind angle? Do you just eyeball it or you have it set with something not shown?
I just eyeball it. For me, having the length of the grind at 1-2 diameters works pretty well. The principle is that the more pointy the grind, the wider the cone on the arc. A blunt point will produce a narrow cone. Kind of counterintuitive. There are so many variables to fine tune TIG welding that it gets confusing early on. Some may disagree, but my opinion is this. First, get your arc length, torch angle, travel speed and rod dip down in that order. After that’s going pretty well, then fine tune other factors like electrode grind angle, cup size, AC frequency, etc.
Really clever,Tim! Thanks!
Just wondering....I've heard that tungsten dust is bad for you being a heavy metal (not the musical kind!).
Is s this true? If so, rigging up some kind of dust collection might be something I'm going try to add to this.
I don't know if it makes a difference or not , do you have to have the point go against the wheel rotation or with it ?
I have it go against the wheel rotation. This is how I sharpen lathe tools to avoid a burr, but I'm not sure that it would make much difference on a tungsten electrode. For what it's worth, my commercial one also goes against the point.
What king of chop saw is that
Looks like I’ve been going the wrong way with my drill lol
Maybe a small finger guard in case ya slip??
Works great though 👍
That would be a great addition. Could be fun to make a formed sheet metal piece too.
You are fast with the delete button😜😜🤣🤣
I would have flipped the guard around and made it so it can't cut your hand. Otherwise great build.
Hey Tim, isn't Tungsten dust bad for you? All the commercial versions that I've seen have the wheel totally enclosed and you insert the rod through a hole that also serves for angle alignment. Later you open the lid and gently tap the dust into the bin. That way you aren't breathing in dust comming of the wheel, like in an open design like yours.
Thoriated tungsten is particularly bad, but it’s better to avoid all of it. Many commercial sharpeners are that way and others aren’t. Either way, enclosing the wheel would be pretty simple and a good improvement. Maybe I’ll do a version 2.
Сколько стоит алмазный диск и где ссылка ? Диск это +100 $ ?
👍👍👍👍👍
Someone is going to lose a finger.
You are going to quickly wear a groove in that disc, especially with no lube. I would make a flat fence that you can just run the tungsten up and down along the disc instead of an insert guide. plus the tungsten diameter won't be an issue. Also that guide only has 1 mounting point, which makes it pivot after awhile if it loosens any. I'd make at least 2 points to secure the thing.
Thanks for the comment! The guide would be a cool variation. I'm new to this particular disc, but I've used other diamond sharpeners that have guides putting the tungsten in the same place and they last for thousands of cycles. Most of the commercial sharpeners work this way. I'm optimistic about wear, but only time will tell.
Bro just drill a hole in the guard way easier, faster and free
Great idea! Thanks!
Just sell me it lol
Nice work, but again I can't help but feeling patronised by your metric conversions - us metric guys know what an inch is as well as what you know a millimetre is!
Thanks! I've had hundreds of comments asking for the conversions over the years, so I include them...at least when I remember to.
Or u can use a flap 😂
y spread all that radioactive dust all around.. yay
