Excellent exposition, Mike. Given the manifold advantages of negative rake scrapers I see no need to use anything else. I sharpen my scrapers with a 30 degree top bevel and 40 degree bottom. That's in large part because I use Stuart Batty's 40/40 grind on my gouges and I don't have to change the platform. Lazy :-) I've found that I need use only a carbide burnisher on the best of modern HHS tools (e.g. M42 & CPM10V). To get my "final pass" burr, I'll polish the top bevel with a diamond card to completely remove the burr before using the burnisher. On really hard woods this leaves a glass-like finish. Clyde
Thank you Clyde, for both your kind words and suggestions, much appreciated my friend.
Thanks for watching

Thanks Mike! Going to grind scrapers as you suggested. Awesome info must try this! Thanks again happy turning! 🪵💫
Glad you found the video of interest Douglas and thanks for watching.
Thank you mike,I'm new at the lathe,and never used a scraper.i was a little afraid at first but after watching this video I can put a bur on the tool, and keep it horizontal and not be afraid of a catch seriously that is awesome.
Glad I could help David and thanks for watching.
Thanks for the info Mike! Perfect timing as I just got in a pair of scrapers id ordered, going to put a relief bevel on them (at the very least) for sure now!
Glad you found the video useful Perry, and thanks for watching.
You’ve inspired me Mike to change my scraper into a negative rake version...I’ve only got one but the video is useful to guide me. I’ll see how it goes. Cheers mate
Let me know how you get on Ivor.
Cheers
Mike
Thanks again Mike for the very informative video! Really helpful for us novices. Cheers
Thanks Mike, I have been increasingly negative rake challenged over the last few months, experimenting with different angles etc. when I should have been concentrating on the burr (wire?) and angle of presentation. This video has explained all of that perfectly. Thank you for making it.
Glad you found the video of some use Michael.
Take care
Mike

Thanks for that Mike I normally use a skew to refine a profile but I have just reground a scraper with negative rake and will give it a go now I know more about it
My pleasure Woody, I confident that once you've found how well it does you'll be sold on them ... I hope ;)
Take care
Mike
Very interesting and most useful. I certainly learned what I have been doing wrong. Thanks for sharing this Mike.
Thanks Pamela, glad to hear it was useful to you.
Take care
Mike
Thank you so much for the thorough information on NRS . I just got my.first one although after watching this I'm thinking of converting my router d nose scraper as you did. I like, "more forgiving " since I am a new turner. This has been quite helpful.
Glad you found done use in the video Suzette, and thanks for watching.
Cheers
Mike
Thanks Mike I will have try this grind out and see how I go👍👍
You'll not be disappointed Barry I assure you mate.
Thanks for watching
Cheers

Nice tutorial and review. I have some small HSS bars and will give a go at making some. I have always had difficulty in interiors of small boxes, etc, This should help. Thanks Mike for the video.
Thanks Bill glad you found the video of some use
Take care
Mike
I shall definitely be putting a relief bevel on my round nose scraper. After watching your video Mike I now understand what negative rake is about. I have used my skew as a negative rake scraper. Thanks for all the videos you do. I've learned a lot from them 😀
Hi T, and thank you,I really do appreciate your support. You will be very happy with the results I assure you.
take care
Mike
Hi Mike, a lot of useful information. Will have to watch a few times to take everything in. Cheers, Huw
Thanks Huw glad you found the video of some use.
Thanks for watching

Thanks for explaining NRS sol well. Keep it up.
Thank you Jim much appreciated.
Cheers
Mike
Very informative Mike, I've only dabbled with NRS but the results speak for the value of the tool. Now I've got top save some searches on eBay.... Thanks for sharing this useful information.
Thanks William appreciate your comments, if you try one I'm positive you'll like it.
Take care
Mike
Thanks Mike very very informative as usual. I always take something away from your videos. Cheers mate
Your kind words are much appreciated John ... thank you.
Take care
Mike
Thanks Mike. I'm a new turner (old man but new to turning). This was very helpful.
Hi Ron, glad you found it of some use.
Thanks for watching
Cheers
Mike
Great video Mike! Been using a negative rake scraper but you’ve given me some tips on how to better prepare the burr. Cheers!
Thanks for watching Scott.
Cheers
Mike
Thanks. Mike. For new turners like myself I very much appreciate the info. I am beginning to create my negative rake scrapers and have been a long time follower of a Reed Gray. He was just starting to experiment the last ime I checked in. Follow up is in order.
Hi ray and thank you I'm glad you liked the video. Reed is a top notch turner and a really nice guy to boot.
Thanks for watching
Cheers
Mike
Neg rake scrapers are fantastic, great tips
Cheers
Jim
Glad you agree Jim, and thank you mate.
Cheers
Mike
Great video as usual, taking the mystery out of this tool.
I have taped a small level to the top of the NRS and it helps keep the edge parallel to the floor until one gets the feel of the appropriate position of the handle. This tip works for carbide cutting as well since the goal of handle position is usually the same.
Thank you Louis.
That's a great idea, and one I use as well :)
Cheers
Mike
PS - Should have remembered to include that in the video ... ah well... the memory is not what it used to be!
A GREAT BIG THANKS Mike, I have been using a carpenters chisel for this job, yes it works but now that you have explained your chisels to me I can now see the advantage of the underside angle
My pleasure Ron, let me know if you like using them.
Cheers
Mike
Thank you Mike. Just the video I need at this moment in time, Cheers1...
My pleasure Ian, glad you found it of some use.
Take care
Mike
As someone fairly new to turning I found this video very helpful and informative. As I do most of your videos. I have two 1/2 inch conventional scrapers. I believe one of them will become a negative rake scraper this weekend.
Thank you Duane I'm pleased that you found the video of use. Let me know how you get on.
Cheers
Mike
This was very helpful for me. I will give it a try. Thanks
Glad to hear that Scott and thanks for watching.

Excellent information, Mike! I often wonder if there isn't some school teaching in your background. Your presentation of information is wonderful. Thanks for sharing your knowledge and expertise. Always very enjoyable, my friend.
Happy Turning,
.....Gord
Thank you very much Gord ... no teacher training .... just a motor mouth ... as some of my watchers remark ... lol.
Thanks for watching mate, always appreciated.
Cheers
Mike
Thank you sir! Good info I will remember.

Hi There Great Videos Thumbs up Scott from Scotland UK Memories in High School Doing Wood Work I Miss it I Never get the chance to do it again because busy life.
Thanks for watching Scott ... you never know mate ;)
Cheers
Mike
Thank you so much for sharing great tips 🤝
....and thank you for watching Tomas, very much appreciated.
Cheers
Mike
Excellent very thought provoking video, Mike. I use 3 negative rakers. A 1” straight set at 25/45, a 1.25” half round set at 30/60. My favourite, however, is The Monster. This is a 1.75” round nose whopper set at 35/35. With the handle it’s a prodigious 2.5’ long. Once on the rest at the right angle the finish is amazingly good and I can start at 240 grit. I have other scrapers but I haven’t converted these as yet. Thanks for a very informative and valuable video.
Thanks Graham, I really do use them very regularly too, and like you find them invaluable.
Speak soon, and thanks for watching mate.
Cheers
Mike
PS - You have got a big 'un haven't you ;)
Great Stuff Mike, I converted a 12mm Crown and also have a large T to remind me which is the top
Thanks Peter, very pleased that you found the video of interest
Cheers
Moe
Thanks Mike. Excellent information. May I suggest that when you are talking about something like a bevel or edge that you anchor the tool to a tool rest or something similar. When you have the camera zoomed in to see detail it is very hard to keep the subject in the viewing frame. Similarly when you rotate the workpiece to show tear out or other surface detail please slow the rotation a bit. All in all this was an excellent presentation. Very educational. Thank you for sharing.
Hi Glen and thanks for your suggestions, I will take them on board my friend, much appreciated.
Cheers
Mike
Cheers Mike great info . Take care.
Thank you Glen
Cheers
Mike
Really awesome video!
Thank you Gary.
Brill, thanks Mike! I've been reasonably successful with the neg rake scraper but occasionally found that I wasn't getting as good a result as before and I now suspect it must be because of the angle I'm presenting with. Cheers.
Let me know how you get on mate.
Cheers
Mike
Hello Mike, I always use a NRS inside my hollowed items, and a few years back was puzzled that they were so rarely mentioned. At school, nearly 70y ago, the one edge tool we used was a short handled NRS (I guess for safety), so I might have been conditioned to their selection, especially as they are so versatile. I have even considered putting a negative rake on my bedan (actually a 5/8" mortise chisel) which can be pretty aggressive. Thanks for all the detail. Bernard.
Glad you concur with my thoughts Bernard, and thank you for the info and watching.
Cheers
Mike
Thank you, thank you. I will convert my regular scrapers with a slight bevel and maybe I won’t get a catch when scraping the inside of a bowl.
I'm sure you'll find it a boon Scott ... let me know my friend how you get on.
Take care
Mike
Thanks for the information! very helpful!
My pleasure and thanks for watching, glad you enjoyed the video.

Great info Mike. 👍🇺🇸
Thanks very much Cortland.

Very informative, Mike. I have been turning for over 50 years, and have never used Negative Rake Scrapers. In fact I have only started to use "regular" scrapers a few years back. When I first started turning , way back in the day, (High school), the shop teacher told us that that was "cheating. That if our tools were sharp we would not have to resort to using them". So I never learned them. That old boy is dead now so I can use anything I want! Thanks for the info.
Thanks Alan ... there are many ways to get to the same result in my view.
If you use a bent spoon with an edge to turn a bowl, no one cares how you got there ... except another turner! ;)
thanks for watching and commenting as per usual my friend.
Take care
Mike
PS - If you do try one out make sure your old teacher isn't looking down on you :)
@@MikeWaldt I don't know. As crabby and mean as he was he might be looking up, but I will give him the benefit of the doubt!
Great stuff as always Mike - +++
Thank you Ian much appreciated.
Cheers
Mike
Thanks for sharing that
Thanks for watching Hassan

excellent video as always mike i had never used a negative rake scraper till last year when i watch one of you other video which you used negative rake and talk a bit about them i know use mine all the time i ave mine grind to 25/45 once again mate excellent tutorial video keep them coming still waiting for the new skew chisel video you said you may be doing can you do the simon hope negative rake please
Thank you Phil, the skew video will materialise I assure you, it's just a question of when! ;)
I have done a video on the Simon Hope NR scrapers ... here's the link:

Scrapers have not been part of my tools. After watching your video - I just might have to give it a go. You produce some fine videos, thanks for sharing. Mark
Thank you mark, give them a try you'll not be disappointed mate I assure you.
Cheers
Mike
Thanks mike
Thank YOU Darusman
Cheers
Mike
Hai mike i'm from indonesia, how i get the knife of lathe?
Amazing how a simple burnishing makes such a difference! Thanks for the video Mike
Excellent video as always, Mike I think the NRS is still underutilized by too many turners. I think it would be interesting to compare and contrast a NRS with a Carbide tool. Perhaps a video Idea as if you needed more.!
Thanks Mike, I actually only use carbide for hollowing ... so maybe you could do a comparison video ... also as if you need subjects to upload ;)
Thanks for stopping by.
Cheers
Mike
WHAT the heck am I doing.!!! It's my day off and I find myself sat down having a cup of coffee watching some guy called Mike Waldt talking about chisels...
Hi Mike...sorry about that....Very informative video..I haven't got any negative rake scrapers as yet but I do find that my normal scrapers can be a little aggressive and catch..I will take your advice ( as always)..and convert one of my older scrapers into a negative rake scraper...nice one mate 😉...All the best.....Andy
LOLOLOL ... you need to get out more mate!!!!
Thanks Andy, always appreciate your support mate, if you try them you won't be disappointed I assure you.
Take care
Mike
Another great video Mike...that has really helped me! I have been having trouble with removing grain tear on the hollow side of my deeper bowls...will this technique help in that regard?
Thanks James, yes it can help, but I have since had good success with negative rake scrapers to reduce and even eliminate tear out.
Cheers
Mike
great video mate, no worries about the stickers....... i sure hope noone else has a sticker with my face on it!! LOL
Thanks Jamie, and a big LOL mate.
Having met you in person I realise that you sticker with the face is not nearly as bad as reality!!!! LOLOL ;)
Take care my friend
Mike
@@MikeWaldt HAHAHAHAHAHA Thanks Mike! and having met you in Person i realised the Welsh are exactly what i thought... Ill leave it there ;) lol
Really helpful video Mike......thanks! Is there a particular type of HSS that holds a burr better than others? I'm planning to buy a negative rake scraper soon. Thanks
Thanks Drew, I just have regular HSS steel in my scrapes mate, seem to give good results.
Cheers
Mike
Hello Mike, Many thanks for another very useful class. I am sometimes a little torn between choosing a standard or negative rake blade and while the negative rake has a major forgiving benefit, it's the complication of grind angles that feels like a faff. Being lazy as I am, I tend to grind the underside to a chosen angle and when in use, on external faces, simply raise the handle, (lower the cutting edge), to a comfortable preference. I think a negative rake side scraper is for me, a must inside boxes and bowls as I need a lot of forgiving.
On a final point, would you agree that a relief bevel is all that is necessary and that further grinds need only be to the underside until the relief wears out. I only ask because I see many that look more like a Skew chisel and I wonder if there's a reason to remove so much steel from the cutting end of the blade? Regards, Glenn. :-)
Hi Glenn, there is no doubt that everyone has there preferred method of whatever we do. I just find the NR scraper right for me, once the grind has been established, it merely needs a quick hone with a diamond card to restore the edge, the same as a standard scraper. I just find the NR more forgiving and it suits me well.
I totally agree with your final point, however I mainly hone and only visit the grinder when a reshape is needed.
Thanks for watching and your input, always a pleasure my friend.
Take care
Mike
Lol I am still at the “what the hell” is a negative rake anything stage 😂I will come back to this later in my development ...
Lol kevin ... I assure you there is no "Dark Forces" at work ... it's just a modified scraper :)
Thanks for watching
Cheers
Mike
Great job mike. Do you sharpen upside down to help with burr
Thanks Ricky ... just normal pass as you would a normal scraper, on the main bevel that is.
Cheers
Mike
Did you buy or make your burnishing Tool? If so where did you get it from? Thank you for all of your great videos.
I made it with a carbide rod purchased off eBay, and just turned a handle for it Bill.
Thanks for watching
Cheers
Mike
Good info. Have you tried shear scraping with them?
Thanks Ian ... no I haven't ... but I will now you've put the idea in my head! :)
Thanks for watching.
Cheers
Mike
Well explained,,, now maybe i can get some use out of my neg scraper, thanks for speaking in a “ Newbies” tongue👍👍😂
Hope you get on OK.
Do you ever use a single or standard ground scraper? Would you suggest that I reshape my standards to reverse?
Hi Gary all but one of my scrapers have some sort of negative rake angle, that one is only used to demonstrate the advantages of the negative rake.
Morning Mike, greetings from Swansea. You were going to test the Triton thicknesser a while back. What’s your opinion?
Hi Coldert, for the money I am still very happy with it mate.
Cheers
Mike
Could one use a skew chisel in the same manner to get a simular result
.
Yes you can use the skew as well :)
Take care
Mike
what size steel shaft on those Mike, I like to make my own carbide tools so would like to give one of those a go.
Hi Julian, they vary in size, but generally are 25mm x 7mm, apart from the HD bowl scraper which is 25mm x 12mm.
Hope this helps
Cheers
Mike
5a.m. watching this Mike! Yes,I'm a dedicated idiot!😁😁😁😁😁😁👍👍👍👍👍👍👍👍👍👍👍
Long live the dedicated idiots say I ... lol
Thanks for your undying support Alan I really do appreciate it mate.
Take care
Mike
PS - You need to get out more!! ;)
Would it not be preferable to use a platform toolrest when using negative rack scraper to ensure the tool is held perfectly flat, with no chance of it tipping ???
It's an option for sure Josev, but in honesty, practice makes it easier, and a degree or so either way makes a tiny difference.
Thanks for the suggestion, and watching.
Cheers
Mike
Does a 35-35 grind cut different than a 45-25 grind even though they both have a combined 70 degrees?
I have to say I don't find much difference, the reason I have some different angles is that they are a result of my initial experimenting, and I haven't altered them.
Hope that sort of answers the question.
Cheers
Mike
