Thank you very much for watching 🤗 - วิทยาศาสตร์และเทคโนโลยี
I appreciate the amount and detail of information you provide in all your videos.
Thank you, really appriciate that
Excellent demonstration! Thanks for taking the time to zoom in and show surface of tools and workpiece; very helpful.
Awsome,glad to hear that sir☺️
Thank you very much for this nice and interesting explanation about R. Raffan scrappers.
Thank you for watching 🤗

Hello Tomislav,
First I want to say thank you for sharing your knowledge 🙂I like the way your demonstrate things and your work ist really great. I'm very thankful to learn from a full-time turner, because I'm only a woodturner as a hobby in my leisure time. I'm doing woodturning 2 years and my skills grow. But working with the scraper doesn't work as good as it should be. It seems the scraper isn't the right tool for every kind of wood?! The most time the results are disappointing.
Stay save and keep on turning 🙂
Greetings
Martin from Germany
Hi Martin, thank you for watching and I'm really sorry to hear you have issues with scrapers, there is a lot of stuff that could be doing wrong and you are right that some woods just don't like scraping .... But with all the proper tehnique and extremely easy touch you should have good results... Just don't give up
Thanks for the lesson Tomislav.
Thanks 🤗
Thank you for the class on scrapers. It answered a number of my questions.
Glad to hear that ☺️ thank you for watching
Excellent video with lots of good information. I use scrapers but I don't use them to shear scrape so that will change. Also, I have a scraper that is perfect to grind a slight radius on and I will also grind the corners back because you made cutting the little groove and bead look very easy.
Best Wishes, Brendan.
Thank you Brendan, glad I could help out.... 🤗🤗
Great video Tomislav! Full of very good information. Thanks for sharing your experience and knowledge!
Take care, Dave
Glad you liked it,thank you very much 🤗
A knife-edge scraper: I ground a scraper to an included angle of about 35 degrees and sharpened it like you sharpen a knife. That is, hone both sides until the "wire edge" breaks off, then hone both sides of the cutting edge with a very fine hone until it becomes almost razor sharp. It will then have a keen edge with no burr.
I present it to the wood flat on the rest and straight on. Surprisingly, it cuts and makes very tiny shavings. The depth of cut is pressure sensitive so you can remove as little wood as you like. It is excellent for finishing cuts and for making slight adjustments to the profile of a vessel. It is described on my website which I referenced in my other comment.
Большое спасибо за видео, Томислав. Эта тема по правильной заточке скребка у меня, оказывается, была пропущена. Я никогда не обращал внимания на заусенец после заточки. Завтра обязательно попробую. Спасибо за науку.
Glad to be able to help out 🤗
Great teaching and amazing demonstration! I am so grateful for the virtual mentorship!
Awsome, thank you 🤗
Great information. Thank you for sharing you knowledge.
Thank you for watching 😀
Tom I find your videos extremely interesting and helpful.Keep them coming .Terry downunder
Glad to hear that, thank you very much 🤗
I think this is a very useful video and will make me rethink how I uses my scrapers.
Glad to hear that ☺️
🕶Thanks Tomislav. Great video.
Thank you 😀
After watching your video I will start using my scraper more. 👍
Glad to hear that 🤗
Thank you, this is very informative. I think I've been using scrapers without sharpening them nearly as much as I needed to
Glad you find it helpfull 😉
Excellent explanation on a topic that is often misunderstood. I like your pencil technique to show the burr. I will be using that.
Thank you Mike, its old cabinet maker thing😉
I have watched many of your videos this is my first comment. Very informative presentation. I now have a much better understanding of standard scrapers and negative rake scrapers. Thinking of making my own. Dan
Thank you Dan, glad to be able to help out
Thanks for the great eduction on technique. Another suggestion for this series is how you choose hand positioning for each tool to allow best positioning and movement of the cutting edge. Haven’t seen it as a focus and it seems you (and Richard R) are very consistent and deliberate in your tool presentation to the wood. For example, both of you hook a finger under the rest often which I think few do but can see it would improve control.
Thank you for suggestion, I'll see what I can do, most of those muscles memories come from work , expirience like Richard, confidents as I'm in this trade a long time and repetetive work..... The more you do it,the better you'll get.....
@@tomislavtomasicwoodturning Absolutely, but I’m sure that your mirroring of Richard’s techniques in hand positioning is not coincidence but because he was a mentor, as many of us look to you, Richard, and others through digital media. Seeing it done, but even better, explaining why you use a particular method of holding the chisel helps a novice such as myself to have the eureka/ lightbulb moment much more expeditiously than our own trial and error which I believe leads to the many inconsistencies we see in hand positioning among turners. I’m not saying there’s only one right way but certainly there are better and worse ways which you and Richard have learned through years of production woodturning that most of us will never achieve. Sorry for the length and many thanks for your videos.
@@gregs5744 no problem Greg, I do agree with what you have said.... I'll do my best to film it best I can😉
Another great video, a lot of good information and very educational. What grit or courseness of diamond file do you use for honing your scrapers? Something that is on the courser side for a diamond file or a finer grit one?
Thank you very much 🤗 I have a set of 400, 600,800 and I believe 1000 grit, but I grab most of the time 400 and 600.... Those work great for me🤗
Once again, what a great teaching talent. I had to learn most of my techniques by myself and using Internet: your explanations are exceptional! I see what Richard does but I understand it with your explanations.
One question : what was the size of your scraper ? I will try to make one with bars bought on internet
Thank you very much sir, I'm glad you can get something out of it 😉
I would highly reccomend buying scraper blade from proper tool manufactures, like Henry taylor,crown etc.... These hold a edge much better.... This one is trapez shape, on one side is 6mm and on the other is little less then 4mm.... And its m2 hss but not the best quallity....
These blades were sold as 200mm bar...
HI Tom,
Loved this video. Would like to grind myself one of these scrappers. Could you give us the info on grinding angles and curve please. Thank you in advance. 😊
There are two same comments,I answer the other one🤗🤗
Great instructional video as always, thanks. Question: when would you roll a burr as opposed to grinding one?
Thank you, When I need fresh edge I go to grinder and I use Burr from grinder,once its gone I roll a new one , 2 times and then back to grinder.... Usually if I want scraper to be less grabby I would use Burr from grinder....
@@tomislavtomasicwoodturning Perfect. Thanks.
Mr. Raffin uses scrapers alot with excellent results . And you too as you have been taught by him. Video is excellent..thank you..What is the angle of the grind on the scrapers??
This shear scraper is around 45, I'll do another video with scrapers on other shapes as well and on those angle changes a bit
Thank you very much, Richard and I talk a lot through email , but we are on different side of the globe, Many stuff I learn by his words or his writen wisdom .... The rest is up to me or other mentee to practice practice and more practice, that part and the feel is something that can't be said or explain.... That ls something that has to be expirience.....hope that makes sense 😀
Thank you very much for watching and support what I do ☺️
Your content is frankly amazing Tomis!!! Thank you. With regards to the "burr", I roll a burr with a burnishing rod, like you would with a flat scraper. I can't remember why r when I started doing ... probably 20 years ago. It does make your scraper peel instead of scrape, eliminating tear out. Again, thanks for your awesome videos ❤❤❤
Great video, when will website be available to purchase your scrapers?
Thank you for watching, it will be my priority after the shop move is over.... So much to do still on new shop😀
Thanks a lot dear Tomislav, that's the one tool and could not get yet...and I want one so bad! 😅
I know that you have already showed how to prepare and sharpen the bowl gouge with asymmetric profile...but still, Icannot find the proper way to do it...( Henry Taylor HCT084, Maybe that particular flute shape is not right?).
So if you a few minute to spare...would appreciate a new demonstration. 😅
I'll see what I can do Boris..... Honestly I burn through one entire bowl gouge figuring the asymetric grind, and still it isn't perfekt sometimes, but what you get is the knowledge what will cut and what mistakes can lead to better grind.... I'll do video quite soon but its on your part to practice freehand sharpening, twisting the gouge up the wheel....😉
In regards gouge flute, parabolic flute or elipse is great for asymetric grind, V flute and U not so much....
If any advice, start by grinding tradicional grind and then extend left wing as much as you want.... Once again Boris thank you for suggestion 😀
@@tomislavtomasicwoodturning Will practice free hand!! and will tell you how I go!! Thanks a lot for your time and kindness! so appreciable in these times...
I've bought an old 25mm x 9mm thick Skew that I want to change to the Raffan style. How many mm up on the left do you grind away? Is the circa 6mm of flat on the right actually flat or does it have a tiny curve to lift the corner up slightly?
Thanks for the video I think I'm probably doing that about right though I'll check out the other scraper video for angle of approach.
I would say your choise is better regards steal, and you are right - its around 6mm curve....the very shape is personal preference for the job that needs to be done.... hope that makes sense 😀
@@tomislavtomasicwoodturning OK thanks for the reply, I'll choose a radius for the left. Many thanks.
Neat. At approximately what angle are you grinding that scraper at?
Thank you, its around 45
I missed what angle you put on the tool?
Its around 45 deegres
What is the degree did you use for creating the scraper?
On this shear scraper its always close to 45
I too find a standard scraper better, and more versatile in my turning
Indeed😀
Affilated links do more work….
HI Tom,
Loved this video. Would like to grind myself one of these scrappers. Could you give us the info on grinding angles and curve please. Thank you in advance. 😊
Glad you liked it 🤗, angle is around 45 deegres, the curves can be what suits your style or need.... Sometimes on the inside you need tighter curve and sometimes more flat.... I'll do video quite soon on this ☺️
