I’m sure I’m not the only semi-newbie turner that needed this. Thank you, Phil.
Good to know, Hubert! 😊
Thx Phil. Count me among the others that needed this! Thx again and take care
Glad it was helpful! 😊
Thanks for this important info. Most turners have always wondered what is meant by a negative rake. You covered it from top to bottom. You gave all of us the ware , when, how, information that was needed. A little refresher course never hurt anyone. Thanks for this valuable info. KEEP ON TURNING 😃
Cool, thanks! 😊
Thanks, Mr. Phil for the awesome information.
Glad it was helpful! 😊
Of course, it's beautiful. My first reaction was that it is missing the pit. I'm a guac fan.
Love Thursday evening.
😃
thank you Phil I always learn something from you. Have a Great day
Thanks, Gary! 😊
I just tried your carbide sharpening technique last night. Fantastic. No longer throwing the old blades away any more.
Great news Craig! 😊
Thank You Phil... I am very late for the show today (working on taxes, ugh) ... I am close to purchasing my woodworking cutting tools and your tutorial will be valuable to me as I sloooowly try to figure out what the heck I am up to 🙃.... Until next time Phil..... TM
I've been putting off my taxes too, Tuffy. Ugh is right! Plus, property taxes are due. I now pay yearly in taxes what I paid to buy my first house! I'm looking forward to your first real woodturning adventure! 😊
Hi Phil , You're tip using the screwdriver really works good . Use it all the time . Thanks Al
Cool! 😊
Phil, I hope to see that ASH one day on your channel…. Fingers crossed…. Hope this message finds you well…. I got into my honeybees for the first time today…. Made a video….
Take Care…. God Bless. Chris
I hope so too, Chris! 😊
Thanks Phil!😊
My pleasure, Todd! 😊
Very helpful Phil thank you
All the best from Lincolnshire UK
Glad it helped, Gary, thanks! 😊
Happy St Patricks Day from Terry in Ireland.. Thanks for the negative rake tips.
Very welcome, Terry, thanks for watching! 😊
I am so happy to have watched this. I had no idea that carbide inserts could be sharpened. Thanks.
Glad it was helpful, Monte! Now you can save some cash! 😊
Thanks Phil for going over the sharpening of the tools. I like the diamond card nice tool. I remember my Grandpa would always use honing oil on his sharping stone when he sharpened his pocket knives. He would get them razor sharp.
Thanks for the show.
Joel
Very welcome, Joel, thanks for watching! 😊
Thanks for the how tos. Sharpening is chore I wish I could pass up.
Sorry to hear that. If you have a good grinder and jig, it takes less than a minute. 😊
Thank goodness for the clarification, because I could never quite catch the middle word (rake). I was guessing negative 'edge' scraper.
Ha, happy to help, Audie! 😊
Good video, Phil. Soon I will have a negative rake scraper! Thanks 😊
Right on, Kevin! 😊
Just received my 4 piece Benjamin Best Scrapers today. Used as is on today's bowl, works great. Anxious to see how well it works once I grind the negative rake.
😊
always great to watch you buddy!!!!!!!!!!!!!!!!!!!!!!!!!!!!
I appreciate that, Don! 😊
Useful information is that video Phil, I use the oil to sharpen the carbides but was unsure about the angle for the negative rake scraper, thanks!
Cheers Al
Glad it was helpful, Al, thanks! 😊
Thanks Phil! I need all the help I can get!
Don't we all, Brenda! 😊
Morning Phil. Great 101 in how to sharpen and keep your scrapers in good working condition.
It's reminded me that mine should really get some TLC.
Tea stayed hot but now the cup is empty so time for another one.
Take care my friend.
Cheers, Huw
Right on, Huw! Keep that cup filled throughout the day and you'll surely have a good one! 😊
Thanks, Phil, I really needed that lesson in sharpening my negative rake scrapers!
Glad to help, Carol, thanks for watching! 😊

I'm glad, Stuart, thanks for watching! 😊
Thanks Phil.Another very useful and clear explanation. Must get sharpening.
There ya go, Kevin! 😊
Always great info for your viewers.

Im kinda new to turning lathe. I picked up some antique tools. 1 was a old craftsman. But these are very interesting an much better. I got about a dozen. Gotta work a fixture so l can properly sharpen them. Hey lm use to carving tools an a maple mallet to make my cups bowls and spoons. But l do have a big cherry tree cup up. Cause l figure there will be much damage while learning lol. Thanks for all your info. You have a gift thanks for sharing.
Thank you, Bobby! 😊
If I was showing a new person how to turn, the first thing we would do it spend a week or more learning how to sharpen your tools. Nothing does more to discourage new turners than not using a sharp tool and they assume they have to spend a lot more money for better tools or that they just can't do it. Sharp tools make the hobby so much more enjoyable but I don't think enough people stress sharpening first.
Good advice, Jeff! And with the jigs you can buy or make, it's so simple, less than a minute! I "almost" like sharpening! 😊
@@PhilAndersonShadyAcresWoodshop After sharpening I get eager to turn a new piece and see how well I did and if I can get more from the tool.
Great information
😊
As always Phil a sharp video
Haha, I see what you did there, Kim! 😊
Thanks for sharing ❤
😊
Thanks for sharing this!
Thanks for watching, Ted! 😊
Thanks Phil, I'm glad to see that you sharpen your tools as I do, and those little diamond cards are a godsend - Cheers!
Yup, agreed, Anthony! 😊
Good evening, Phil.
I really like a negative rake scraper. Thanks for the lesson on sharpening.
Any time, Ray! Yes, they are so much easier to use. 😊
Extremely helpful & useful Phil. Great vid & very good use of ur time, Phil!
Thnx a bushel! Enjoyed it! 👍👍👏👏👏👏👌👌

One thing nice about the BB scrapers is that they sharpen very quickly
😊
Great tips Phil, thanks again.
My pleasure! 😊
GREAT STUFF as usual, THANKS
😊
Great information
Thanks Phil 👍
😊
Very informative
Glad you think so! 😊
Did the same thing with the Benjamin's Best scrapers. Absolutely love them. A nice fine shaving comes off the burr. Not self feeding like regular scrapers.
There ya go, Leo, thanks! 😊
Thank you as well Phil😊.
Great information, thank you.
😊
Nice, Phil. Thanks for the sharpening tips. 😊😊😊

Good to see you on this no-bowl Philday.
😊
As always thank you Phil. I know I can benefit from your experience and knowledge.
Glad to hear it, Steve! 😊
I started turning last Fall and have heard quite a bit about the advantages of negative rake scrapers. I just purchased larger sized one and want to turn my small round scraper into a negative rake scraper. Your video is just what I needed. Thanks.
Perfect, I'm glad it's helpful, Boyd, thank you! 😊
Thanks for the sharpening tip Phil. Very helpful.
Good to know, Doug, thanks! 😊
Thanks for the tips. I enjoyed the advice and video
Glad it was helpful! 😊
Awesome tips. Thank you. Keep up the great work.
Thanks for watching! 😊
Thanks Phil. I may now have the impetus to make my own negative rake scraper.
Cool, thanks, Garth! 😊
Great information Phil, I’m heading down to the shed to find those expensive carbide tips that I couldn’t bring myself to throw away and get them sharpened up, and my scrapers as well. Thanks for sharing.
All the best to you.
Regards Jim
Good news, Jim, glad it was helpful and you can make those carbides last so much longer! 😊
Been waiting on this one Phil. Excellent job explaining and filling in some gaps for me. Thanks!!!
Good to know, Mark, thank you! 😊
Thanks Phil for updating this important info. Much needed. Have a blessed week-end😊😅😊
Thanks for watching, Kid! 😊
I need to try these.
Good deal, thanks, Michael! 😄
Great video man...!!!! Sharpest thing known to mankind..!!!
😊
Great video Phil. I have ground all mine that way. 👍
😊
Great video Phil.
Thank you, Jack! 😊
That’s great, thanks Phil! I’ll try this over the weekend!
Cool, thanks, Danella! 😊
Thanks.
Thanks for watching, Anna! 😊
Like the figured wood seen briefly in that video! Also the tips shared with us. 👍👍
Awesome! Thank you, Teddy! 😊
I am slowly turning my regular scrapers into negative rakes by simply working on the top. But I like to maintain the steep angle on the lower bevel. I’ve also experimented with sharpening so that the grinder wheel is going towards the edge. It feels awkward the have handle lifted up but it produces a bigger burr.
Cool, do what works for you, Bill! 😊
So glad you put this video out as I just got my Benjamin’s Best 1 1/2” scraper Wednesday.
Perfect! 😊
Great information, Phil. Very helpful to many of us! Thanks for sharing, buddy! 👏👏👏
My pleasure, Gord! Thanks for watching, buddy! 😊
As far as sharpening a carbide cutter....The dulling of a carbide cutter is due to the wearing down of the beveled edge where it meets the larger diameter (top) face creating a 90º face to the top face on the beveled diameter. It may be ever so small (.010" or so) and can be seen if held under a light at the correct angle. Lapping the top edge needs to be done enough to get below (remove) that 90º worn face or the cutter will still have issues cutting. A magniying device makes seeing this very easy to see such as a headstrap magnifier or a microscope (if one is available).
Thanks for the tip! 😊 I just go by feel to see if it is sharp again.
Thanks for the tool tip's. Being some what new to turning, tips and tricks of turning and or tools for turning are always valuable to me. Be well my friend.
Glad to help, Linda, thanks for watching! 😊
Lots of useful information Phil. I just bet there will be a lot of people wishing they had not tossed those dull carbide inserts away.
I definitely like using the oil.
Take care,
Gary
Thanks, Gary! 😊 I'm sure the card would load right up without honing oil! And, yeah, those inserts are expensive, as you know!
Yes very expensive. So I decide to 3D print a couple. Well that was sure a waste of time LOL
@@ThePapa1947 Hahahaha!
I know you don’t have to but I sharpen my carbide tips about every other time I use them. Makes them last longer and your cuts are so much cleaner.
😊
Have been watching your videos for some time now, maybe a year, and do enjoy your creations! But I was interested in your negative rake scraper. Found out why you like it so much and I will be getting a scraper and grinding it like you do in the video. Thanks for putting out the video.
Cool, I think you will find it easier to use, Darwin, thank you! 😃
Next video, Sharpening bowl gouges? Thanks Phil, I’ve been wanting to see what you use!
😊 I did that in another video, Kevin: ua-cam.com/video/PUGFEgJTogA/v-deo.html 9:35
@@PhilAndersonShadyAcresWoodshop Phil, I do remember the beginning of that video, but forgot the sharpening part. That was back when you were a young pup! Seen the grands lately? I see our youngest almost everyday since we are babysitting her. She will be 1 in two weeks. Lots of laughs watching that one! Best wishes, Kevin
@@KevinCoop1 Yeah, I see them pretty regularly. Enjoy yours Kevin! 😊
Nicely done Phil! It was the angles for the negative rake scrapers that I didn’t know about. I just got a couple of diamond cards for Christmas, so I’ll be for sure trying the carbide sharpening!! Thank you!
Cheers, Rick
Excellent! Thanks, Rick! 😊
Thanks Phil I had a go at turning a n unusual piece of beech wood healover today video is on my channel. In the premier your name came up Thank you for producing these great videos
Sounds great! 😊
Hi 👋 Phil from Phil, Great tutorial on explaining your negative rake scrapers, I have been doing some Woodturning yesterday and today, for the first time in awhile. And I have been thinking about making a negative rake scraper as I have a large piece of tool steel which in some respects is no good for man or beast, It is part of a cup of soup that I had made nearly 40 years ago so I am thinking of cutting a segment of it, Great tutorial on your negative rake scrapers, and on the cutting angle 📐, PHIL FROM THE DARK SIDE OF THE MOULIN FRANCE.
Cool, thanks, Phil! 😊
Good info Phil, I bet another of folks Didn't know that carbide cutters could be sharpened, and dang they are pricy.
Thanks for the video.
Glenn
Pricey and some are so thin you can only sharpen a couple times. 😊
👍
😊
You should stick your negative rake scrapers in the freezer before using them, when you take them out to use them you'll get an even bigger brrrrr!! 😆 🤣 😂
LOL!
Really interesting Phil, I'll do my best to remember it for if I get to actually take up turning, rather than just watch you chaps.👍😄
There ya go, Jude, enjoy! 😊
Howdy Phil👋
😊
I'm so glad you did a vid on sharpening carbide! I'm new to lathe turning. Got my JET 1221 in November. All I have are cheap WEN chisels / carbide cutters at the moment.
Two questions: Q #1 can please you give a link or brand name for the diamond sharpeners and oil? Also, could you please do a complete bowl sometime only using carbide tips?
I'd like to see how you do it and if you get smoother cuts then I. I've had a few nasty catches and a couple bowls fly off the lathe. My last bowl actually blew up and I ended up going from a good size bowl to a salad bowl with what was left over. Thank you so much Phil!
F.Y.I. I do want to get regular lathe chisels but will have to save money for them, the grinder, CBN wheels, guides....etc I didn't realize this was going to be such an expensive hobby! lol
If you scroll down to "Frequently Bought Together" you'll see everything I have, CJ. At least, in my preferred brand, I do have cheaper diamond cards. www.amazon.com/DMT-D3EFC-Dia-Sharp-Extra-Fine-Diamond/dp/B00006IIO3/ref=sr_1_6?keywords=diamond%2Bcard&qid=1679015962&sr=8-6&th=1
For me to do a bowl using only carbide would be torture for me and probably all the viewers. I don't like using carbide tools and only use them when nothing else will do. I feel like it takes the "Art" out of turning. I can't feel the wood in the same way I can with high speed steel tools. I feel like I'm just steering the tool around and that takes the fun out of turning, sorry.
Yes, sharpening is expensive and I will discuss that in an upcoming video. I probably have about $800 into my sharpening setup.
If it makes you feel any better, in the beginning I couldn't turn worth a darn with HSS and I had bowls flying left and right! I switched to carbide just so I could turn "something!" Still had wood flying everywhere! After awhile I learned how to use conventional tools. Now it is very rare for me to even come close to getting a catch. You need to practice using a light touch, that's the best advice I could give anyone. Hope all this helps! 😊
@@PhilAndersonShadyAcresWoodshop Thanks for the link and advice!
It'll be at least a year before I can afford lathe chisels and a sharpening system. Until then, I'm going to get diamond cards for the carbide tips.
I'm disabled and was looking for something to help get me off the couch after gardening season is over. So, after watching countless lath videos from great turners and teaches like yourself, I knew I had to try it for myself.
Like you, I love live edge and when possible, with bark :) I've mostly been using wood from a massive 200 yr old Hackberry tree that came down on my property last year. (2 tree companies told me they thought the tree was about 200 yrs old) The main trunk was wider than my truck hood!
The color, patterns and spalting in this Hackberry wood amazes me every time I work with it! Absolutely stunning! Sad thing is, before I thought about getting a lathe, I burned most of the tree. Now I wish I would've known what was hiding behind that bark and that I'd get a lathe!!
Thanks again Phil. Your time answering my questions and the videos you produce are much appreciated! ~ CJ
Sorry obviously have got the name wrong it is the attachment that you put into a drill to sand bark and rough natural edged on your bowls you use it all the time in your videos
Ah, Sand O Flex, Phillip. The metal ones that I use are no longer made. You can find them on eBay along with the newer, lighter versions which I think I prefer. But, watch pricing on eBay, people seem to think these things are collectibles and they are not. The best place I have found for selection and pricing is here: www.supergrit.com/tblproduct_woodworking_sandoflex.html Hope this helps!
Awsome thanks so much Really enjoy your wood turning love the way you use wood that most turners would use as firewood
Thank you Phil for this video!!! I wasn't aware of how to make a negative rake scraper or how to sharpen a carbide tip!!! Does it work the same for a square carbide tip???? Thank you again!!!!!
Yes and I should have pointed that out, Lori. Any carbide that has the flat top (all of them?) can be sharpened in the same manner. 😊
Could you show how you set up your degree angle on your grinder? Also, what grit grinding wheel do you use? Thanks for this video.
Mark, I did show that in another video. I'll give you the link. I have two CBN wheels, 80 grit for shaping and 180 grit for sharpening. 😊 ua-cam.com/video/PUGFEgJTogA/v-deo.html
Excellent information Phil. What type of wheel is on your grinder?
I have two CBN wheels, 80 grit for shaping and 180 grit for sharpening. 😊

Good to hear from you, Grammy! 😊
Thank you Phil! I always have problems transferring that 36deg onto my grinder table, knowing what angle I need between the table and wheel - I’m presuming it’s 180-36=144 degrees…?
I have another video with more sharpening including how I determined that angle, John. 😊 If you want to see it, it is here: ua-cam.com/video/PUGFEgJTogA/v-deo.html
@@PhilAndersonShadyAcresWoodshop thank you again!
@@PhilAndersonShadyAcresWoodshop watched and absorbed - I hope! I love the setting at your home and shop, but I couldn’t work with no insulation or heating! I’m a softy, I know!
Thanks for video. One question. Can I change the shape on my scrapers. I have an extra 1/2" square scraper and a round nose scraper. Can I change them into a shear scraper and a bowl scraper? Want to make both negative rake.
Sure you can! Just don't overheat the edges. Take your time, you will get it right! 😊
Hey Phil. Quick question, what CBN wheels do you use for your grinder? I have the same grinder as you but I’ve been using the stock wheels that it came with. Awesome video as always!
I have 80 grit for shaping and 180 grit for sharpening, Robert. If I were buying them again, I would get 1 1/2" wide instead of these 1" wide ones. Easier to keep the tool on the wheel. I've adapted and don't usually have a problem with it but would still get the wider wheels given the choice. I do like the square edges on my wheels rather than the radiused ones you can get. 😊
Hi Phil glad your doing this video. Just wanted to ask is honing oil the same as cutting oil. To me it's the same I could be wrong. Please let me know if they are the same please
Cutting oil is heavier, honing oil is very thin like water, Ray. 😃 I think you would have a hard time cleaning cutting oil off of a diamond card.
@Phil Anderson - Shady Acres Woodshop ok I'll go over to Woodcraft and look for honing oil 🛢 I'm like you I like doing things the easy way thank you so much I appreciate that.
