I just bought a similar tool rest and was looking for information about how best to use it. Your video was exactly what I needed. I watched it a couple of times. Thank you and Fine Woodworking for showing us how.
I've watched a lot of videos on how to sharpen chisels/plane irons on a bench grinder. This is the first video I've seen that explained the process in a clear manner. It's the only video I've seen on the subject that was actually helpful. I ended up getting a jig made by Peach Tree, from Amazon. It works great. I use it with a vintage hand crank grinder, so there's no worry about overheating and losing the temper. I can lock it into the sliding mechanism, and check it with a small machinist square. Then I can slide it left and right, with my left hand, while cranking the grinder with my right. I briefly tried doing it free hand on an electric grinder. Very briefly. That was a disaster. I'm pretty sure the guys who do it free hand are using some sort of black magic.
Very informative video, I appreciate it very much. I'll be getting one of those jigs and hopefully I can sharpen things quickly and easily just like you demonstrate. Thanks for sharing!!!
That is a slow speed grinder running at 1750 RPM not the "usual" grinder which runs at 3600 RPM. The higher speed is going to heat up the tool even faster. But I like the idea of the rounded grinding face of the wheel which I will tryout tonight.
Still a relevant way to sharpen and great tips on how to set proper angles, but I've heard you should NOT quench the metal! Severe temperature changes in the metal created by dipping it in cold water has the possibility of creating hairline cracks in the metal at the thinnest part of the blade. If your tool is that hot, you've probably left it on the wheel too long, or are pushing too hard. A really neat trick is to use a heat sink from a discarded computer to help cool the steel without risking changing the metalurgy of the steel - it works amazingly well. I've also noticed that the specific grinder used by Asa in this video is a "low" speed grinder (
As some one from the wood lathe world, which put my flat work world mostly on hold, this sharpening video is 2 to 3 years out of date. CBN grinding wheels are so much better than standard wheels, that the standard friable wheels are now obsolete. Check out D Way grinding wheels.
Excellent, thank you! Subscribed! I needed the tool rest information, and grinding chisel blade tips. 1. Can you recommend a good quality grinding wheel dresser tool? So much junk on Amazon. 2. Anyone know of a decent CBN grinding wheel? Apparently it is better (and cheaper) than a diamond grinding wheel as it does not heat up easily and second in hardness after a diamond. So you get 4 things with a CBN (Cubic Boron Nitride) wheel: Bushings are machined and fit well reducing vibration of wheel, material is a heat sink and does not overheat, it is much harder than regular stone wheels, you do not need to prep the wheel with dressing it like a stone wheel. Prices on Amazon run $70 - $80 each for CBN wheels, and they vary in arbor hole size. Some are 'diamond' coated but avoid these. Get the all CBN material. Not sure of what grit to get either -80 or finer, to sharpen chisels, drill bits, and kitchen knives. I am a novice at sharpening and bench grinders. I could really use some help. I also need a 6" bench grinder and was considering the Metabo. It is easy to slip off the housing guards and this is a big advantage. Please advise - anyone?
In that case, can the grain size of 120 be used for polishing? I've got at a disposal an even finer wheel, I suppose it should be used for final polishing of the cutting edge?
@@ognjenradojevic, "Final Polishing" of what "Edge"? What are we talking about? Lawnmower Blades, or Carving Chisels? Grits like 36 & 60 are mostly for coarse work in the metalworking trades, especially on the 3400 RPM bench grinder. While a 1750 RPM (slow speed - dry) bench grinder would be better for wood working tools, I find 100 & 120. or 150 grit, with a light touch, is much better for shaping and getting the wood working blades prepped for stoning than anything coarser. Don't forget, for most all blades, the back inch or so must be flattened before you shape the edge, and again after you stone the blade you have to once again hold the back of the blade FLAT against the stone to remove the burr with a few passes. Then it's as sharp as you've made it.
Newbie question: I have (new to me) a sealed Craftsman commercial 6" grinder and two new wheels. The nuts that go on the arbor tighten clockwise on the Right side and counterclockwise on the Left. There is no place on the inside of the wheels to grasp the shaft. How do I get the nuts tight on the arbor without the shaft spinning ? There is no place where the shaft can be held like on a Dremel, and a wedge will not work, as the arbor just spins. What is the proper technique to tighten these nuts ? By hand perhaps and the spin does the rest ? Jam nuts don 't seem to be a very good idea. Perplexed.
senorboardhead; You need to use both hands and maybe use a wood wedge while you tighten the nut. Your grinder will need both wheels to be balanced (not wobbling). Then and only then do you dress your wheels true. If done well your grinder will hummmmmm along with you while you sharpen your tools. An important thing is to have FUN doing it eh… ÜïÖ
This is what I've never understood about bench grinders: If you are chisel grinding an edge, don't you want a flat grind? Doesn't the wheel lend itself to a concave edge geometry?
Yes. The bench grinder is to prep the blade for the sharpening stone. You should flatten the final inch or so of the blade on your stone before grinding to have a reference point for the shaping on the grinder. Then, after the grinder shaping and then the stoning, you must again lightly flatten the back to remove the burr.
Ann Cluckey . some people prefer it that way. Ive known people invert the whole rig just to have a grinder that spins upward. It depends on what you need it for. People make jigs for this and that.
I just seen that tool rest for the first time, can you tell me what it's called again? I need to grind down aluminum panels the size of small pictures. I need to grind the edges to a 45 degree angle. I might be able to slide the panel in those thin slots. Do you know of similar tool rests? Thanks!!
Nice video but you only sharpen half of it you forgot the most important part before you sharpen the Bevel you most flatten the back of the chisel or you’re not going to have the sharpest tool possible Flattening the back Is the hardest and longest part of sharpening a chisel in many times overlooked I hope this helps you going forward
Agreed. And, for anyone not familiar with the concept, you do not flatten the back of a blade on the bench grinder but on your sharpening stone - Oil, Water, or Diamond.
I was hoping since it was a fine homebuilding video I could use it for my students...no safety gear at all. I cant show that to my students...safety first!
how would you go about griding the teeth off of a chainsaw chain? I saw a prop chainsaw in a video that bench grinded the teeth off a chainsaw chain and made it harmless because im trying to make a horror movie and want it to be as authenthic as possible.

Hey, thanks for this video. Very informative, including mentioning the diamond rougher and the veritas jig. Helps a lot!
Love your tips, especially the chisel tip. Very sharp.
Thank you very much for this video. One of the best I've seen yet.
I think a more appropriate title would have been "How to sharpen a chisel" Since a bench grinder can be used for far more things.
great job teacher, novice wood turner. struggled sharpening cutting tools. thanks.

Thank you! There is a ton of good info here and great "how to" for those getting started.
Great video! Really enjoyed it!
Very helpful. Thanks for sharing!
Very useful information for someone new !!
Nice tutorial, thanks for sharing.
Thankyou! Very clear informative video!
Great video I like to watch videos that are general because if I pick up one new thing it's a positive.
Do you need another compliment? You have it. Outstanding! Thank you.

Glad to see your comment. I'm very new to bench grinders. If I invest in this expensive CBN Wheel, do you have a brand name that is good?

Great Tips Excellent Video
thanks for the tips
A helpful classic video.
Extremely helpful many thanks
And Fine Machining! Excellent!
Nicely done.
Thank you, sir.
I’m having a hard time getting my chisels like that! That’s great sharpening.
I always fimd it very satisfying sharpening my tools this way and feel the tool work its way through the material with ease!
Thank You So much 💪❤️😀
What about using a grinding tool for carving things like gemstones? Or does that take another set of tools entirely?
Awesome! kindly a link where to buy this adjustable rest?
Can you use this on some dull kitchen knifes?
Wonderful thanks
can you use plastic on a bench grinder. I have blocks of hdpe plastic that im trying to clean up
This video is great

Any tips on grinding a standard chisel to a skew chisel?
NORTON Friable wheels in UK are named FLIXOVIT
Fucking pisses me off when companies do that.
The most likeable person i've seen on youtube
Can u leave a link under this comment for the little rest thingy for the blade?
Yes is used to sharpen knifes, axe and all those things
Normal grit size for roughing out is 30 and for finishing is 60 ( makers advice)
In that case, can the grain size of 120 be used for polishing? I've got at a disposal an even finer wheel, I suppose it should be used for final polishing of the cutting edge?

@FineWoodworking Great Video. I found a great deal on a Bench Grinder but the week is really small ~5" What do I give up with a small wheel?
NORTON wheels have large bores - need to be supplied with bushings to suit your grinder spindle.
If your grinder is bogging down can you fix the motor?
This really helped me with my knife making. Thought I made a mistake getting a bench grinder instead of a belt.
I have both and do the same as you, as nice as the belt is I actually prefer the grinder.
Jackson Brooks can you use the bench grinder for handle shaping? I’m looking to get either a bench grinder or a belt sander.
@@anthonyglassey3200 Get a 2*72 or 2*48 belt grinder.
Is this grinder also used for sharpening knives?
Thank you
you can.
Faisal Almaiman use a sander
TekNyc74 no
which is the model of your Bench Grinder, very thanks
norton advise grit size for roughing out is 30 and for finishing is 60
Where can i get the angle tool rest ?
what make/model is the grinder in this video?
I just bought a new grinder and didn't look at the kind of wheel because I looked at the 50% off ;) That's my kind of tool.
What grain has the wheel you're using?
very helpful thank you
What do you do with the burr at the end?
If I want to use MDF wheels to sharpen knives, do I buy a bench grinder? Do I want 6" or 8"? What shaft size is most common?
How to prevent the grinding stone kicking back the tool ?

The Bob Ross of benchgrinding...
🌹Greetings 🌹 and Bravo 🔔
what kind of grinding stone is he using?
This jig only works with long shank chisels. And flat shapes
Thanks.
What brand is the grinder thanks
How come no mention of grinder wheel speed?
How are the first two tips of a bench grinder *basics* video to throw away your wheel and throw away your tool rest?
I hate my old wheels I have one that is warped so it shakes by bench to pieces andthe other one would deteriorate if I used it
What grit that stone?
Just a question what is that vaccuum looking thing in the background i have seen them only a few times and never knew what they were
they suck most of the dust, attached to cutting or grinding machines
Thebeardedman Man there extractor fans to remove dust or fumes
Can i sharpen my knives with a benchgrinder :O?
1:22 what is the name of the tools ? And Where I can buy it?
thanks for some actual knowledge and vaiable actual info
which is maybe SO missing in the zoomer (or whatver ) age
God speed u
The Axminster 100245 tool rest includes the straight edge guide
I'd use a square to keep the chisel, or plane blade at a 90 degree angle. Freehanding isn't any faster.
Yes, with a wetstone.
And create another barely visible bevel.
This will keep it sharp for longer.
Is that an 8in bench grinder?
what sharperning wheel do you use?
+Eddie Tamez Any fryable wheel will work. Lower grits usually work faster.
Wheel name plz
What grit wheel is best for sharpening tools?
Lower grits (courser) do the work faster and heat the tool up less. 60 or 80 grit is a good place to start.
FineWoodworking b
Gerri Barnes a
rough grit use 60# OR 80# if want better surfacing result of the edge use finer 150# then finer
This is what I've never understood about bench grinders: If you are chisel grinding an edge, don't you want a flat grind? Doesn't the wheel lend itself to a concave edge geometry?
Thats actually an advatage. Because you need to sharpen less steel with a fine water stone.
Would one remove the burr on a flat stone after grinding?
While honing yes, but not on the grinder
Yes. The bench grinder is to prep the blade for the sharpening stone. You should flatten the final inch or so of the blade on your stone before grinding to have a reference point for the shaping on the grinder. Then, after the grinder shaping and then the stoning, you must again lightly flatten the back to remove the burr.
I have a mini grinder,but the wheel turns up and away from me..whats up with that?
you installed it with wrong way , or the wheel quality is not ok .
牛恒振 I baught it the way it is. I want to fix the issue.
Ann Cluckey . some people prefer it that way. Ive known people invert the whole rig just to have a grinder that spins upward.
It depends on what you need it for. People make jigs for this and that.
and what do we do with the burr?
Justino_Jose remove it to make it even sharper
Justino_Jose remove it by grinding or sharpening it it flat at no angle on the back of the chisel
This is worth content in this days where any idiot is call influencer
What's happeneds if you use the side??????
Highly not recommended. The wheel can split and/or shatter.
wouldnt it be better to use the sliding carrier rather than wobble all over the place . nice information though.
I just seen that tool rest for the first time, can you tell me what it's called again? I need to grind down aluminum panels the size of small pictures. I need to grind the edges to a 45 degree angle. I might be able to slide the panel in those thin slots. Do you know of similar tool rests? Thanks!!
+lou garcia that will probably take quite awhile but the tool rest is made by Lee Valley/Veritas. Check out their site.
+lou garcia aluminum will clog your wheel
From a safety perspective I suggest installing an eye shield and wearing safety glasses. Thanks
no eyeshields?
Hes wearing glusses already mannn
fryable? friable?
LOL. Only if your cooking "Chicken Frickin'z."
Nice video but you only sharpen half of it you forgot the most important part before you sharpen the Bevel you most flatten the back of the chisel or you’re not going to have the sharpest tool possible

tzero440 just buy bike chain and save yourself the effort
Max Krul it wouldn't jump off the saw?
tzero440 probably would. If you have a pair of pliers and a grinder go for fucking up that chainsaw chain
