- Negative rake scrapers are very easy to sharpen. In this video, I will explain how I set up the grinder platform and sharpen the negative rake scrapers that I use in my woodturning. If you have some of my negative rake scrapers and aren't sure how to sharpen them, this is what you need!
Thank you to Stuart Batty and Bonnie Klein for showing me the Negative Rake Scraper concept.
Please visit my website to see more woodturning tools. www.cindydrozda.com/
If you are wondering where to get that grinder support platform, it is made by Stuart Batty Tools and sold by Woodworkers Emporium in Las Vegas USA. The platforms are not listed on the website, give them a call to ask about them.

Thank you Cindy, video is so easy to follow and understand.
Thank you so much Cindy for a very easy to understand demonstration of sharpening these newer complex tools. You make it simple and take out the guess work!
Thanks for the video I was looking for a solution for an annoying scraper and needed a reminder about using a skew. And I have a few scrapers that I just don't use that I can repurpose.
I'm glad you liked the video. Specific purpose scrapers are easy to make out of any old tool or piece of steel! Happy turning!
Thanks for sharing Cindy, looking forward to using your techniques for sharpening and watching any future videos.
Thanks for sharing, Ms. Drozda. Great sharpening tips.
Thanks Cindy. Great video as always.
Great presentation; it's so clear! Thank you very much Cindy. -Mike
Thank you for sharing your expertise on sharpening these scrapers. I now know where I've been going wrong and I look forward to putting the lesson into practice. 🙂
Thanks for the instruction Cindy. It was much appreciated. Looking forward to SWAT.
Very informative and constructive. Thank you so much. Always great to have a refresher.
Wow, thanks for all this knowledge!
More great information, Cindy. Thank you!!
Thanks Cindy for this lesson, now I understand the principle of negative rake. Hope to grind my own tools and using them on the lathe.
Excellent presentaion. Answered my question about sharpening negative rake scrapers. Thanx.
Nice job Cindy, Great to have the 50 degree a constant for all the NR tools.
Awesome delivery of spot on info, think people some time make things harder then they need be, you explain this stuff so well.
A superb tutorial Cindy.
Take care
Mike
Excellent! Great instructional on Negative Rake sharpening. Thank You! :)
Great Info Cindy and thank you!
Hi Cindy. Thank you for this, you’ve completely demystified negative rake scraper sharpening, useful shapes and how to easily improve my Wolverine platform. Cheers from Canada and happy new year!
Very good explanation and good detail. Thanks for sharing your knowledge.
Good information, Cindy!
This was very helpful Cindy. Thanks!
Great video Cindy!! Thanks!
Thanks Cindy!
Thank you for sharing,excellent tutorials.
nicely done Cindy
Great instruction,information and filming.
Very nicely explained!
Cindy you are terrific! thanks
very impressive I like the tool rest
Thanks, an informative video. Good job.
Hi cindy I was real happy to see your video on this to sharpen cause i've had trouble sharpening the scrapes properly. It's been About 20 years and I saw one of your in person demonstrations in Wyoming. Anyhow good to see how to sharpen is scraper
Excellent, thank you
I have been thinking about making cut outs on my wolverine platforms but I’ve been hesitant and I will have to have someone else to do it because I don’t have the metal working tools. Making the overlay is probably the best solution. Thank you so very much Cindy for the fantastic idea.
I haveaneighbor who is a machinist and I had him add 2 - 1 inch tabs on the top of my Wolverine tool rest. Now it passes a full inch on either side of the wheel. It's all flush and smooth. If you have a machine shop handy or know a friend. It cost me 10 bucks...neighborhood rates.
Thanks Cindy
Thank you for sharing
Thank you so much for your video
Очень познавательно!Спасибо!
Very good information, missing your finials videos!!!
The finial videos are still on my channel.
I know Cindy, I was talking about something new, if you have available to share with your followers!!!!
Thanks Cindy. I wish I had the range on my platform that you have. I just spent a half hour tweaking my tool grinds.
Those platforms are available! Woodworker's Emporium (Las Vegas) has them
@@cindydrozda Thanks Cindy. Just my luck, sold out. I'll have to make due hand sharpening for now. Great demo today.....colour adds so much more to the figured wood. Hopefully I have a piece completed for next weekend to show off.
@@cindydrozda Stuart's FB page they are out of business. Has this changed?
@@DaveBellStickermetimbers Well, that's disappointing. I hope they're planning to get more. It's the best grinder rest out there. You can do fairly well with the Wolverine platform by cutting out the notch around the wheel, or putting an overlay on top of it like I show in one of the videos. Robo Hippy also makes an adjustable rest that's good.
@@DaveBellStickermetimbers I know for sure that Woodworkers Emporium is not out of business. But Stuart Batty Tools is. After Stu quit his business, Woodworkers Emporium started selling the grinder rests and some other SBT stuff. He had those rests in stock last summer. Not Stu, Christian at www.woodworkersemporium.com/
As always, great information. Thank you for sharing. Where did you get the angle setting tool for the grinder platform, I didn’t see it on your site? Also, do you ever use a burnisher for hooking your burs? Thanks.
The Raptors are available at Craft Supplies and Packard online. The SBT gauge (silver square one) is available from Woodworkers Emporium in Las Vegas.
Cindy Drozda Thank you, I never saw Woodworkers emporium before, but looks like I’m ordering all 3 SBT gauges.
I don't use a burnisher on my turning tools. Just haven't tried it yet. I use a burnisher on my cabinet scrapers.
Cindy Drozda lol same here, that’s why I asked. I use my burnisher on my card scrapers but haven’t tried it on my turning scrapers. Thanks again, I appreciate it.
I noted your angles or included angles seems to be mostly symmetrical, is that by preference or simply because it is easier because the platform angle is already set. Ie 25 degrees and 25 degrees.
Edward, It doesn't seem to matter if the angles are symmetrical or not. Setting one platform angle and sharpening either side is good on tools that I might use either way up. I do some with a different angle top and bottom.
Thanks for the video. One question though, to raise the bur is the wheel turning toward you or away from you? If turning towards you, wouldn’t that raise the but on the bottom of the tool vs the top?
Trey, The wheel is turning toward me, and the burr is raised on the top of the tool. Try it and you will see.
@@cindydrozda Thanks for the fast reply! I moved from a Tormek to CBN w/SB Tools platform about a year ago and absolutely love it! It just seems counter intuitive to raise a bur on top when grinding down but I will definitely check it out.
Hey there Cindy. Great channel. Where do you get you’re blanks for all of your scrapers? Thanks
I use Doug Thompson's blanks.
@@cindydrozda thank you. You are one amazing turner. 👍👍
Which grinding platform are you using? It looks rather substantial.
It's made by SBT, and sold by Woodworkers Emporium. Link in the description.
Thank you, could you post a link for the grinding jig?
Just saw the jig in the comments.
I put it in the text below the video.
Do you use the 25 degree setting for the point or pyramid tool?
Hi Gary, I shape the pyramid tool horizontally on a 0 degree platform, and sharpen it on a diamond hone. There's a live stream recording on my channel that shows how I do it.
@@cindydrozda thanks Cindy. The tool is held against the wheel on the tool support at 0 degrees at an angle of 25 degrees? Do you have the link to your video I couldn't locate it...sorry

Hello Cindy thank you for your videos but most of all the clarification on the subject matter. I watch several other channels and where I have a question, viewing your channel you have answered many questions. My question is are these various tools in this video purchased and you keep them sharp or did you make them from raw steel. If you have made them Could you please advise the best steel material “ the metal type” or number” to make a tool with and your best method of heat treating them. Thank You very much David Ray
Hi David, You can either make Negative Rake Scrapers or you can buy them. The ones I use are available on my website www.cindydrozda.com/. If you make your own, use the best steel you can find and it will hold an edge longer. Better to buy the steel already heat treated. Heat treating HSS is quite a process.
When I bought my scrapers in Nashville I thought you said they were ground at 20/20 degrees or an included angle of 40. But here you are using an included angle of 50 degrees
Johnny, I think you heard me wrong in Nashville. The ones you got are a 50 degree included angle. I sharpen them just like in this video.
Cindy Drozda thank you, it doesn’t surprise me that I got it wrong, there was so much information to absorb. This old dog is slow to learn new tricks.
@@johnnyhugheswoodworking595 And that symposium was an overload of information! Fun, but chaotic!
Cindy Drozda thank you again
What is the rpm of your grinders I noticed they were slower than usual.
The grinders are 3500rpm. Not slow at all. That's considered a high speed grinder. If it looks slow, that's just an illusion from the camera.

Hi Rodolfo, I think you are asking about the grinder support platform? It is made by Stuart Batty Tools, and sold by Woodworkers Emporium in Las Vegas, Nevada, USA. They are online here: www.woodworkersemporium.com/ The platforms should be in stock by March or April.
Didn't see that I'm so sorry
these tools are shaped skew chisels used as scrapers; if your gouges are sharp and you know how to use them how much scraping do you really need???? sometimes "advancement" in technique is confused with marketing.
Agreed,
Oh no... a skew as a scraper. Lol
