- Moresuperhard CBN Grinding Wheels, 6 inch 80 or 180 Grit: amzn.to/3t1APor
In this video: Building a grinder utilizing shop scraps and an old motor. This grinder will utilize a pair of Moresuperhard CBN Grinding wheels.
CBN Advantages
1) Very long lasting
2) Wheel never needs dressing (always flat)
3) Fast stock removal
4) Better heat dissipation
5) Can be used wet of dry

One has to admire a man who builds his own tools. Nicely done sir.
Thanks, I really enjoy it.
Mark I really do like the idea of how you made the tool rest. It would be an easy rest to incorporate with most bench grinders. Love the creativity. Thanks as always for bringing us along.
Thanks again. Yeah, on this grinder it's not going to be an issue but there is a reason you never see this on grinders. The pivot point sticks out further than the front of the wheel. Normally a tool rest that does this is on a pair of trunnions. Like on many belt sanders, bandsaws and table saws have.
I'm looking at my grinder, and can't figure a way to adapt a similar rest to replace the mickey mouse rests on it. I guess that's another reason the belt-drive grinders are superior.
Love your grinder! It's very well engineered and should work great, be trouble-free, and easy to maintain! It also looks professional, and darn nice!
Thanks 👍 It was a fun build.
Another fine creation Mark. The grinder looks great in it's red & black livery, very classy.
Interesting thanks!
EXCELLENT! And, no distracting, screaming background music!
I agree! music has it's place but not in the whole video or loud enough to block out vocal. Thanks for watching.
Nice music touch Mark. Thanks
Thanks Terry, I like the music when the grinder is on the turntable but it doesn't fit with mist videos.
Great project, well executed. Two suggestions: for aesthetics, replace the toggle switch with machinery on and off buttons; for functionality, add an angle gauge on the tool rest to set the tool angle you want. But I agree, this thing will last forever.
Well I like the simplicity of the switch. In fact I've had issues a few times with smaller toggles and push buttons on machines going bad. I remember 20 years ago I had a table saw with a 25 amp toggle switch for power. I replaced the switch after 6 month and then it went bad again. I then mounted a box to the saw in put in a standard light switch. It lasted the next 10 years and might still be working (I sold the saw). Quality light switches are cheap but made very well.
The angle gauges is a great idea! I will likely do this.
When your TIG welding light gauge metal as you were on the two tubes, start at each end and weld in at least 1/2 inch, then alternate your welding from each end to maintain a cool temperature. It's more effective than "speeding up". Also, when you come to the end of the piece you won't burn through the metal because you ending on "weld" and not the thin end piece of the tube. For me ... I keep a water filled spray bottle handy to quench the heat when welding light gauge product.
I think that is good advise - Thanks!
Really nice addition to your shop!
Thanks!
Nice one Winky. Love the colour too. Class engineering. Happy 2024.
Steve.
Thanks! Yeah I like the color too.
You've done it again, another great project, it turned out very nice indeed.
Enjoy the holidays and all the best for the new year.
Thanks, you too!
Looks better than anything you can buy from a store, very beautiful
The red paint made a big difference. Thanks
I hope we’re neighbors one day.
Nicely done!
Haha... thanks.
Outstanding design, implementation and construction! 👍🏼
Glad you like it! It works great
That machine came out nice👍🙂
I think so too! Thanks
If you haven't tried soaking mild hot rolled steel in white vinegar to remove mill scale you should give it a shot. My process is to soak the metal for 24-48 hours, rinse with fresh water and then put it the ultra sonic cleaner with Simple Green Pro degreaser for 5-10 minutes. That usually removes all the rust and mill scale without grinding anything. I bought several pieces of black ABS pipe of various lengths and diameters at Home Depot, capped one end and put a screw on plug on the other for doing long parts like angle iron. Of course those won't fit in the cleaner so I just rinse in water and a lite scrub with a Scotch Bright gets all of it off and ready for welding, painting or powder coating with very little effort. Good luck.
Very interesting, I'll give it a try, Thanks
@@WinkysWorkshop It works great
I will definitely try it!@@TheAyrCaveShop
Mark I really tip my hat to you sir', you are a true Craftsman and Machinists. I've been following and watching all your wonderful videos, and the tools, machines, just your vision of your "ART/TOOLS" are so Amazing. I just had to let you know. Thank you so very much for showing & sharing yourself to us All
Wish you and your wife a very Merry Christmas my friend
Thanks for the great comment! Merry Christmas to you as well.
Astonishingly beautiful ❤
Red makes it pop! I agree, it looks good 🙂
Great build Mark! You should be proud of your work.
Good to hear the Vevor tools are working well for you.
Thanks for sharing
Cheers
Thanks, I think inverter technology has changed the market a lot. I'd say most welders work about as well. The Vevor welders are just incredibly cheap. Several years ago finding a TIG under $200 would have been impossible and anything under $700 didn't even have HF start.
Very nice, functional, and pleasant on the eye, well done 👍
Thank you very much! Yeah, the red makes it pop.
Great design and execution. Like the I can or will try to make it out of what I have at hand. Thank you for sharing the projects builds and restorations .
You are very welcome, thanks
Nice job. I like the design, very industrial looking.
Thanks!
Elegant design and build!
Glad you like it!
It's a real beauty. Well done.
And very useful information at the end. Thanks for sharing.
Your welcome, Thanks!
Great work, as always! 👍👍👍
Thanks - Love my TIG 🙂
Excellent job, Mark. Looks beautiful and seems to work top. I like it.
Thanks, so far it has worked out well.
Nice work Mark!
Thanks!
Nice job Mark and thanks for sharing!
Thanks for watching!
Nice build! You should be proud!
Thanks, I am kind of proud of it. I looks nice. Love my TIG welder too. It opens up possibilities.
Inspiring! @@WinkysWorkshop
Beautiful!
Thank you! Cheers!
Catchy opening tune!
Thanks, I like the music later in the video when the grinders on the turntable
Very cool & super neat as usual.
Thank you! Cheers! Its much better than the first one I made.
That really came out nice! Your work is always finished well. Merry Christmas!
Thanks and Marry Christmas to you as well
Very nice machine you built
Thanks, it was a fun build.
another fine job
Thanks, I love CBN wheels!
Awesome !!
Thanks!!
That turned out gorgeous Winky.
Excellent project with excellent results.
That red makes it pop! Thanks
That was a Brilliant video
Wow, thanks!
Very impressive sir !
Thank you kindly!
U have attention to detail and what a great job I like it👍
Thank you so much 😀 It was a lot of fun to build.
Nice job Mr Winky, like the use of the neoprene belts
Thanks, the polyurethane belts are great up to about 1/3 HP
Looks good did a great job on it will enjoy it for a long time.
I hope so! Thanks
Nice project looks good and works well. I may just have to make one of these. Thanks for the video.
Go for it! But also keep in mine they will work well on any small grinder.
What a beauty design fine tune with years of experience Congrat Sir !
Wow, thanks!
Another JWD. Very neat design too!
Thanks you sir!
Well done Mark, Really turned out nice, one of a kind project 👍👍
Thanks, it's the red paint. But yeah, it works great.
Mark, yet again you have made a tool that i need for my shop, very nicely done. merry Christmas.
Cool, go for it... and thanks!
Oh man that was a great idea
Glad you think so, Thanks
A major improvement in time efficiency when re-pointing your welding electrode (carbide/tungsten) is to use an air-die grinder with a 2" 60 grit wheel. If you have a build-up on the shaft or tip of your electrode, you can use any part of the grinding wheel to shape the electrode back to a round shape. You can do the same to reshape the tip of the electrode to any "point configuration" you need for the work. REMEMBER though that when you get the point shape you want, only use the left 1/2 of the wheel (depending on rotation) to "groove" the last 1" of the electrode. You want the micro-grooves to be traveling in the same direction as the electrode which allows the arc to form properly. This is a surface issue only and no need to press hard on the electrode.
Groove the last 1 inch? Never heard of that. I do sharpen with the grinding marks running the length
@@WinkysWorkshop Same thing. If your accurate enough to groove just the tip then stay with it. I can't do that with the die-grinder so I back down the shaft a little (about 1"). By using a bench grinder, my electrode kept grooving the wheel so I switched to the die-grinder. It's way faster. Also, and not for everyone, since the speed in re-shaping the electrode is much faster, I routinely re-shape 3 or 4 at a time. This way I can keep up the production. Your work may not benefit. Using the die-grinder really helps my efficiency.
First Class. Great design. Thanks for allowing us to watch…..
Your welcome, thanks for watching!@@billkurek5576
@@richardgreen7811I've been using my old CBN wheel. So far its not hurt the wheel although they say it will eventually wear the wheel. I'll probably get a diamond wheel and make a jig for sharpening.
Hello Winky, you really did an awesome job on your CBN grinder, I really love it, I especially enjoyed your commentating through the whole construction process that really excelled the whole video, keep up the good work, Merry Christmas and have a safe and happy New Year to you and your family, and thanks for all the projects and knowledge you shared with us all throughout the year, Cheers from me.😷👍👍👍👍👍
Thank you so much 🤗 Have a great Christmas and new year.
Very Impressive solution !!!!! Merry Christmas Mark 🎄🎄👍🎄🎄
Thanks, you too!
Artwork my friend! 😉
Thank you so much 😀
Very well done. Another great video. Aaron from Canada.
Thanks 👍
Very interesting and well thought out. Mate have a Merry Christmas and a Prosperous New Year with your family.
Thanks, you too!
Man that is one nice milling machine!!!
I love my mill. 🙂 Thanks
Estupendo trabajo señor Winky y feliz Navidad desde Málaga (España).
Merry Christmas from the US 🙂 Thanks
nice build. You could put some deg graduations on both sides of your grinding support arm. would make accuracy adjustment easier. just a thought.
Great minds think alike. I was thinking the same!
👍@@WinkysWorkshop
Really nice bit of design and construction- well done Mark. And (when it comes) Happy Christmas! Les in UK 🇬🇧
Same to you, Thanks
Hey Mark you should be proud of your grinder it is well thought out and should give years of trouble free service. I hope that you and your family has a wonderful Christmas.
Thanks 👍 Same to you.
Put machinist jacks under the ends for support
That might have helped some but most the force was horizontal. I need to make some jacks!
That is so sweet!! How you figured out the axis for the angled tool rest to stay close at whatever angle-I’m amazed! 👏 Its beautiful
Thank you very much! Much easier than a trunnion like a table saw of bandsaw table. .
Another Nice machine for your Shop^^
I think so too, thanks!
Put a magnet in the end of the tube. It will collect all the steel dust from the tools. Regards from Australia.
I thought about magnets too. I have a piece of PVC pipe under it now. I probably need to put covers over the wheels it I wasn't to improve it more. Probably not worth the effort.
Good job Winky! It's been awhile and hope you and the family had a good holiday season!
Thanks!
@WinkysWorkshop if you don't remwber me, I was the one who submitted photos of my custom made dials for my lathe. That was from one of your earliest videos so it's been awhile. :)
@@firsttimejongbuild Oh yeah, I remember now, nice dials! You're in Canada.
@WinkysWorkshop yes sir I am! Glad you remembered! Glad to see you're still going strong! All the best!
That grinder turend out fantastic and i really like that roller you made i may have to make one for myself have a merry Christmas and a happy new year
Thanks 👍
Great grinder design and build. I have been wanting to do something very similar with an old flat belt driven grinder but was struggling to figure out how to make it compact and was thinking of something similar to yours but with a flat belt. I think I may switch and try your welded round belt idea. Keep the great ideas coming.
As long as the HP is not over about 1/3rd the round belt works well. I almost went with flat belts drive kind of like my drill press but I was worried about tracking.
I like it! Now I've gotta build me one, great video winky, keep'um coming..
Thanks! Keep in mine any bench grinder will work.
@@WinkysWorkshop but we gotta build one,lol..that's what we do.
So true! @@kentuckytrapper780
You got a Roll Roys grinder,Mark.Thank you and happy holidays.
Hahaha... maybe so, that red makes it pop
I changed my mind.Either Roll Royce or Cadillac
Cool, thanks@@angelramos-2005
That turned out fantastic Mark. Looks like a smooth running machine, well done. I have a CBN wheel on my grinder for sharpening my HSS wood lathe chisels (can be used for metal lathe HSS as well). We have them at the woodturning club too. Ironically the wheel I got was wider than the stone wheel that came with the grinder, so I'm going to have to re-make the guard and cover so it fits the wider wheel at some point (I will need to build a bender/ring roller).
That bender you have looks good and works well. I have a ring roller on my list of things to build so I will get there one day. Lots to do, so little time...
Merry Christmas and Happy New Year from NZ.
Thanks! That little roller works well. I made it before I started a youtube channel so no video. I made it using 1--1/4" bar stock with 32 mm OD bearings on the ends. Then I drilled and reemed the 2 angle iron frame for the bearing for the two bottom rollers. This allowed me to assemble the frame and slide the bearings and roller through the holes. On the side that doesn't show in the video (opposite the crank) I tied the 2 bottom rollers together with a small chain. Oh... and I used a screw and washer on the edge of the bearing holes to hole the rollers in place. You might have a design in mind but here's some pictures of the one I made. photos.app.goo.gl/mBJrpmLPpJTMy6fd6
@@WinkysWorkshop Thanks Mark, the photos a very useful. Can you tell me what some of the measurements are? Like the width of the top roller in between the bearing guides on the sides. E.g. this will be the max width that you can bend. The height of the rollers from the base, the size and thickness of the angle iron. Are the chain and sprockets from a bike?
@@thehobbymachinistnz Here's another link with more pictures and a few measurements. The angle iron came from a swiss made machine at work so its actually metric. The dimensions can be change a bit wider etc. photos.app.goo.gl/uvd7v5xQ1U81CzC19
Probably dressing will be needed in some future
No way.... its CBN grit imbedded into aluminum and nickel. As long as you never grind mild steel or carbide it will last a very long time.
I love watching your no nonsense and nice work. I worry to much over stuff yet am I just not so practical. Id like to add 8" wheels but have to rework the work tables now too. Fine or course first? I can't both.
I would go with the 180 grit wheel (fine). It still removes stock fairly fast and gives you a better finish.
Well, I was initially sceptical about the guards. The wheel's not going to explode, is it? But, looking at what you've made, I was wrong! That dust collector is really good. Congratulations Sir!
I use my cbn wheel for carbide. Yep, it's probably knocked the edge off the abrasive, but it grinds hss to a mirror finish and has withstood said abuse for over 5 years.
I ground carbide on my old CBN wheel. I've not seem any change. I just know that they recommend against it. The guards were for dust and also so that partials don't fly back in my face.
I have been thinking of getting a CBN wheel(s).
Aside from the slightly undersized bore on these wheels they are fantastic.
You know how you prefer just hss or cobalt lathe bits, but you will use a cemented carbide bit right? Are you able to dress up any of the carbide inserts to get them to run better (less force I guess)? A lot of them have kind of a dull edge.
I usually use inserts. Cemented carbide on rusty metal because its cheap. CBN will grind carbide but it shortens the life. With HSS is lasts almost forever. So I never grind carbide.
General Rule of Thumb is 1 amp per thou thickness, so 1/16" 60 amps or a bit less. Came out well. Great Job. Now onto the next project ? How is your CNC wpood lathe going ? not heard or seen any more since the toolpost upgrade. Regards from Australia.
Yeah, I think I was using a bit more amps but it worked great until the end. The CNC lathe works fantastic. I don't use it very often but I did a job for a guy maybe a month ago and it worked fantastic. The only issue is dust collection. Lots of cleanup every time I use it. I'm designing a new lathe that will be very unusual (if it ever happens). Right now its just a drawing. photos.app.goo.gl/KUqq1Nrox8ZEfp9G9
Sweet as
Thanks!
how long did it take to radius that bit? How hot does it get? A regular wheel would turn the edge blue did that happen? That's the first time I've seen anyone use the CBN wheels. When I first heard you talking about it, I thought it was some of those pills you order online.
The grinding speed is about 50% slower than mild steel on a standard 80 grit stone and the heat is drastically reduced. You can put a full radius on a 1/4" HSS blank in about 30 seconds without water cooling it. It's fantastic!
What rpm is your motor rated at? What range is consider optimal for CBN?
The speed of the CBN wheel is very forgiving. They say 1750 or 3450 will work although they also say the optimum is 1750 for a 6 and 8 inch wheel. My motor is 1750
@WinkysWorkshop Thanks for the prompt response and videos. I'm kitting out a hobbiest workshop, and your videos are a treasure trove. It's motivating me to revenovate/commission the Smart & Brown Model M I acquired last year. Enough projects here to keep me busy for a long time!
@@eocallaghan No problem, glad you like my videos. I never heard if a Smart and Brown but it looks like a nice lathe
CBN is trash -diamonds all the way baby !
Actually CBN works better than Diamond for HSS. It cuts faster and at lower temperatures. If you grind carbide diamond might be a better choice however.
@@WinkysWorkshop I grind everything on a diamond plate i bought from ebay,drill bits,hss,carbide.Wont brake a speed record but for 10$ it gets job done. . . like a regular grinding wheel it needs cleaning from time to time,i do it with a old plumbers dried up clear silicone.
2000 grit plate does amazing finish on carbide ,for taking of chunks i use 80 grit.
Best thing is i made simple wooden backplate for cheap bench grinder so whole setup is like 40$.
For hobby use great ,professionals dont grind tools anymore(magical world of inserts) anyway.
Also if you ever get tired of grinding hss just cut it off with a 1mm stainless steel cutoff wheel -bosch makes good ones that are 1$ each.
Hss can go up to 600C° and it is really hard to get that temperature on diamond wheel unless you push in like a gorilla.
I didn't hear how you chose your grit sizes, maybe I missed it. I have to watch a lot of videos with the sound turned way way down because I'M THE ONLY ONE IN THE HOUSE WHO CARES ABOUT REAL STUFF AND NOT THAT CRAP ON TV. Ok, there I said it. Sorry to yell.
Haha... I'm not sure I said why but I chose 80 and 180 because that's all that was available. In my opinion you could get by with only the 180.
