I have really enjoyed learning to turn on a lathe and how to sharpen the tools to do the work. You are a really good teacher. Thank you for going to the trouble to make these videos. I wish people could just take the good from your videos and keep their opinions and negativity to them selves.
Shawn: I picked up turning again last November. I was looking up tutorials on the Tube and ran across your channel. I have binge-watched almost every one of your videos! You are an awesome instructor.. Keep up the good work Bro !!
I am just getting started and after my brand new bowl gouge was chipped (from my own misuse I'm sure) I thought I'd have to order a new one or wait until I found someone to show me how to fix it. I watched this video and gave it a try, and what do you know, I was slicing though oak like a champ. THANKS!!
AT LAST, Finally, someone who can explain the 40 40 grind... tried to follow several videos but ended up confused, ( and I was an A maths student) got it now Thank you,,,, will be out in the shop at the weekend on the grinder....
Thank you for all of these videos, I finally got a lathe on the weekend and made some spinning tops and a small vase/cup with no previous experience, all from absorbing your channels lessons. Cheers 🤙
Sure wish I had discovered your channel sooner. Excellant explanation on sharping. Think a couple of my gouges wouldn't be so short that I need to replace them. Sharpen alot and hace to take off too much to fix what I mess up, lol. Since I'm in forced retirement from beating (BEATING) stage 3 lung cancer I spend a lot of time in my little 12X16 wood craft shop now. 25 yrs as a scroll sawer I decided to get a small lathe and turn pieces to accent some of my scroll pieces. Long story short, the scroll saw doesn't see as much time as it used to and I just upgraded to the next size lathe last month and ordered a chuck for it this morning. Hope I get over this bronchitis by the time the chuck gets here, chomping at the bit, the yard works just gonna have to wait, LOL. Thanks a bunch for sharing your knowledge.
Such excellent educational videos, I would like to shake your hand! I teach turning and have always used the traditional 40:40 grind but never thought to add a slight radius for shear scraping. Thank you for all the hard work you put in to your videos.
Years of punishment my father called teaching sharpening traditional bowl gouges...you do get better but he had an eye for it I never did. Love your vids and those swedes the other day were impressive, thanks for sharing
I saw your demonstrations in Skiatook, OK. I learned then that I love the way that you teach. I've gotten a ton of knowledge from you since then. Thank you!
I’ve been using the 40/40 grind on my bowl gouges but was having trouble with the flange angles. Thanks for showing the simple layout on your grinder angle support plate and explaining the way to proceed.
I have the Wolverine system and love it. I’m a beginner turner and truth be told I’d stop turning if the sharpening didn’t get easy. I’ll probably give this a try. Thanks for sharing.
thank you for showing this . i looked at alot of sharping videos trying to find out what you explain in this video . how ever can you use this grind for all your other gouges as well roughing and spindle gouges not skews . i sharpen my skews by hand with a diamond stone .
Just tried ron browns method for the 40/40 grind and i love it. Never got such a good finish off the tool. Would eventually like to switch to free hand sharpening like this tho.
I was a little confused until I realized that, although you’re pointing at the top angle between the tool rest and the grinder wheel, the angle that’s 40 degrees is the bottom angle (under the tool rest as you look at the setup from the side). That makes the top angle 130 degrees (90 plus 40 degrees).
oh, ok. Thanks for your help. So the best is saving for a Wolverine system. I need the vari grind attachment and the oneway Wolverine grinding grid. Then I'm set for bowl gauges?
I gave this a go today on two gouges. They cut very well, however they tend to cut uphill better which is a bit challenging if you are a leftie. Good video. Much appreciated.
Thanks for this and your other videos; you do a great job. I'm sure that this will help a lot of people who have found tool sharpening to be quite a challenge. I must point out an error that you made when illustrating the angle of the platform on the pedestal grinder. when you drew the angle, you indicated that angle between the platform, and a line tangent to the wheel at the point of the gouge, to be 40 degrees, when it clearly is not. The angle that you indicated would be 140 degrees. You, obviously know what you are talking about, but that could be very confusing to someone who is not especially good at geometry.
Maybe if I had two of the same gouges but, alas... $$$ It'd be a waste of a lot of steel to regrind and you'd need to do them back to back fast to get any real sensation of "feel".
Great video again! Have been wanting to try that grind. You are the only one I found to have given an in depth demonstration of it. Even though you did it on a v gouge, will it still work as well on a u shape gouge? My daughter and I want to get into more bowl turning. Check out our recent lathe purchase on our Instagram page, Helger Woodcrafts. With a 40/40 grind and the new (to us), used to anyone else lathe, we can really go to town! Thanks again for your great videos.
If I may jump in here -- I attended a workshop that Stuart gave, and he told us that a U flute is problematic. First, his techniques with the 40/40 grind depend on having a small nose. This is only possible with a V flute or parabolic flute (which is his preference). Second, the geometry of a U flute makes it very difficult to avoid getting a concave wing -- a big no-no. I think you might see that if you look at the good, clear drawings in this video and pay attention to the tilts and swings presented. If you ever have a chance to see Stuart live, jump on it -- he's enormously entertaining as well as being a great teacher. Clyde
Thanks. It's a lot harder with a U because there are an infinite number of bevels going around, no single spot is the same. With the V you really only have to worry about 3 and blending together. Though I will say, if done right (really hard) I'm told U's cut better in some situations. I don't own any U's. No sense buying something you can't sharpen consistently when their are alternatives you can.
I’m sorry but you didn’t have a 40° angle consistently across that. You swept the wings back at 40° but you didn’t have 40° from the cutting edge back to the thickness of the wing. Like you did at the tip. Because you had the tool rolled over too far. And you can see it just looking at your grinder marks.
The whiteboard and your ability to draw while giving a logical explanation is invaluable.
Thanks, you're the first one to really show me where to measure the 40 degrees.
Best woodworking educational channel on RUclips. Thanks for making these videos.
Thanks
Thank you soooooo much.my dear lovely teacher.I look your some videos,great.your teaching style is so good.

Thanks, very useful information I’ll try that.
Thanks for a clear demonstration of the 40 40 grind. I plan to use the technique tomorrow on a bowl gouge.
Go for it.
good stuff, simple is always best! easy to understand and hear. thks. enjoyed your zest for woodturning and teaching.

Thank you for taking he time to share your knowledge..
Thank you so much! This is the first video that actually explains how to sharpen.
Look for Stuart Batty video's. He covers sharpening in just about all of them.
Excellent. Absolutely very well explained.

el mejor video que he visto sobre como hacer este tipo de afilado, muchas gracias. ya estoy suscrito
I don't speak French
I’ve been using the 40/40 grind on my bowl gouges but was having trouble with the flange angles. Thanks for showing the simple layout on your grinder angle support plate and explaining the way to proceed.
glad it helped.
Thanks for this video. Watching this while setting up my new grinder
Thanks
Thanks for posting this...should make life a little easier!
Thanks
Thanks men. U are great
Dude. Thank you. This is a big help.
Great video, I was able to get my 40 40 grind after watching. Thanks for posting
go make it dull
I have the Wolverine system and love it. I’m a beginner turner and truth be told I’d stop turning if the sharpening didn’t get easy. I’ll probably give this a try. Thanks for sharing.
That's a good system. It won't let you down and definitely adds consistency.
Man you are a wealth of knowledge, i hope someday i can learn 1/2 as much as you know about turning
It's all perspecive. To a lifer I'm an idiot.
This guy is Awesome! Thank You Sir!
Thank you, so easy to follow :)
Good tuition 👍🏻👍🏻
Thanks for the simple explanation of the 40/40 grind! I'm a new turner and it really helps. Stuart
Very good explanation...thanks👍
Thanks
Your teaching techniques come across really good 👍
Thanks for taking the time to show everyone.
thank you for showing this . i looked at alot of sharping videos trying to find out what you explain in this video . how ever can you use this grind for all your other gouges as well roughing and spindle gouges not skews . i sharpen my skews by hand with a diamond stone .
Glad it was helpful
you have such a good way of explaining things, makes things a lot simpler & interesting
Not bad, don’t have a jig yet so might try that. Thanks 👍🏼
Thanks
Good video. I think it will be a big help, thanks.
Just tried ron browns method for the 40/40 grind and i love it. Never got such a good finish off the tool. Would eventually like to switch to free hand sharpening like this tho.
As always a great teacher, easy step by step instructions
Thanks for the short videos I really enjoy them hope you keep making them.
Thanks
Great video and reminder, for all!!!
thanks for your time and skill...
Thanks
Many thanks, great video. You had the tool rest set at about 40, the swing side to side 40, but you rotated the gouge too, I assume about 40??
nope. get the grind face flat to ground.
@@wortheffort many thanks for your reply, got it now.
Always love your videos!
Thanks
Thanks for the info
You bet
VERY good video,,,keep up the good work,,,
Thanks
thank you . ah relief angles on cutting tools any type . on internal just remember to use a steeper angle . on em good luck .
Perfect timing. I just bought my first lathe a couple of weeks ago, and don't have a sharpening jig (and don't intend to, really).
Get after it then. Make a mess.
LOL - and a mess I made! I swear, I made nearly 20 POUNDS of wood shavings and sawdust, making a few bowls.
I'm hooked.
Love these videos. Thanks for making them!
Thanks
Dang! I was just watching Stuart's video on this topic! Timing is everything I guess! Thanks!!
Ya, he's got teaching this technique down.
Thank you!!! Very helpful and nicely done!
Thanks
U simplify the process for many. Hope the new guys find u...
Thanks
I was a little confused until I realized that, although you’re pointing at the top angle between the tool rest and the grinder wheel, the angle that’s 40 degrees is the bottom angle (under the tool rest as you look at the setup from the side). That makes the top angle 130 degrees (90 plus 40 degrees).
it's the resultant angle on the tool people reference.
Great, it makes sense now to this hard head!
Very helpful, thanks!
Thanks
i think you need to measure the 40 degree angle referencing off the top edge of the grinder platform and not the lower surface
How would I go about starting from scratch with this grind if I have a different grind on my tool.
Is the Kodiak system good, have you used it ?
Never used it
What grit is the grinder wheel you were using?
Do you know what the robert sorby 3/4" "Texas grind" bowl gouge is?
Marketing for something you can do yourself.
Nice video , very helpful. About the grinder, two concerns: whta is the rpm you use and the grid? Thanks
It's a standard slow speed grinder (1750?), 80-120 would be fine.
Thanks ? don't even know your name. Excellent Tutorial. most importantly time saving = sharper chissels = more time turning = better quality.
where can I find that platform for the tool rest. I like this video, I don't have the budget for the expensive wolverine etc.
mark verspaget that is part of the wolverine system.
oh, ok. Thanks for your help. So the best is saving for a Wolverine system. I need the vari grind attachment and the oneway Wolverine grinding grid. Then I'm set for bowl gauges?
mark verspaget the whole video showed that you don’t need varigrind.
Thank you very much. I'll try to find a platform for the grinder. This video helped me. Thanks
I gave this a go today on two gouges. They cut very well, however they tend to cut uphill better which is a bit challenging if you are a leftie. Good video. Much appreciated.
Great video! Can you do a quick tip on how to hollow grind a chisel? I would really appreciate it! Thank you.
Check out my Intro to woodworking series.
Thanks for this and your other videos; you do a great job. I'm sure that this will help a lot of people who have found tool sharpening to be quite a challenge.

Neil Silcock you’re right. It’s the result on the gouge I was referencing.
Awesome video! What grinding wheel do you recommend? There are soooo many choices!
Norton Fryable. My take is they're pretty commoditized.
@@wortheffort Great. Thanks for replying! I am learning a lot from your videos.
as the grinding stone gets smaller, the angle will change. FYI
This vidieo simplified things... I have cbn wheels and a wolverine jig thats new and im not to confident in using this set up yet.
It would be interesting to see you turn something with a 40/40 grind vs a regular Wolverine grind. Is it easier, faster?
Maybe if I had two of the same gouges but, alas... $$$ It'd be a waste of a lot of steel to regrind and you'd need to do them back to back fast to get any real sensation of "feel".
Understand. Have you tried both and, if so, what is the difference?
Just got the Hang Yan protractor via Amazon. Thanks for the 40-40 instruction. Is the 40 degree bevel optimal for skew chisels also?
Thanks...realized it the second after my post. Yours and several good features on the subject. Keep up the great instruction.
So its not possible to grind a U gouge to a 40/40?
Anythings possible, it's just much harder. The flat interior wings of a V are much easier to freehand when learning.
What kind of grinding wheel do you use? And what grit?
Norton, 36, 80, 120
👍
Thanks for the great videos. Can I ask what kind of bench grinder you use? Seems to run very true with no wobble.
Great video again! Have been wanting to try that grind. You are the only one I found to have given an in depth demonstration of it.

No sense buying something you can't sharpen consistently when their are alternatives you can.
wortheffort thanks for the response. Guess I’m now on the hunt for a v bowl gouge to try this out.
Ask 10 turners how to sharpen the tools, and you'll get 12 answers and a fistfight.
never fight a person with a freshly sharpened tool. just an FYI.
I’m sorry but you didn’t have a 40° angle consistently across that. You swept the wings back at 40° but you didn’t have 40° from the cutting edge back to the thickness of the wing. Like you did at the tip. Because you had the tool rolled over too far. And you can see it just looking at your grinder marks.
It's different if you have a parabolic or U gouge, key is to get it horizontal to the ground. If it's +/- 5* I don't think it matters much.
wortheffort fair enough
