  • Shear scraping will often produce the best surface off the tool. Here you see three useful shear scrapers.

    Richard I've been turning for a few years and still consider myself a beginner, I love your videos, no rambling introductions just right down to business with clear and easy to follow content, thank you !

    Richard, I like they way you include things such as catches in you videos. They emphasis what not to do as well as why they happen.
    Thank you for sharing 11:03 these great videos.

    Probably the most watched and appreciated use of any turning tool, the ‘dreaded’ scraper, the skew possibly runs a close second. Thank you for this demonstration, well worth watching. Greetings from Tasmania Australia 👍😁🇦🇺🦘

    Perfect! Thank you. My only problem now is that as I progressed through the video I went back and forth from "definitely making a skewed shear scraper!" to "nope, definitely making a spear point". So now I guess I'll have to go root out a couple of semi-retired tools from their attic slumber and make one of each.

    Ever since you've been posting masterclasses on TH-cam, I've converted two of my hefty skews into scrapers!
    After watching this, I'll make a spear point chisel 😊

    You answered my question about drying difficult wood about a week ago. I just wanted to say thanks again for taking the time to answer me. After I got your reply, I looked at the rough turnings, and the ones with thicker bottoms were the ones with splits. I will be taking more care when rough turning from now on.

    Hello mr. Raffan and thanks for this video. I am in Italy: scraping here is very frown upon. Basically a second grade way of working compared to gauge cutting, being cutting with a gauge is sharper and cleaner…
    I started woodturning about one year ago, so I am way too at the beginning to have whatever strong opinion… sometimes it seems to me a bit of a fad.
    To me scraping seems a whole world of opportunities, your pieces seems extremely well and fastly done, with a well refined finishing.
    This is why I am eager to understand better how you use scrapers.

    • @clarencegreen3071

      A properly sharpened scraper is in fact a cutting tool and makes shavings instead of dust. You can see very fine shavings being produced at 6:12 in this video, and the surface produced is very good. Tomislav Tomasic has an excellent video on sharpening a shear scraper, which I highly recommend. -Doc Green NC/USA

    Hi Richard. I don't have any shear scrapers but I'm about to make me a couple after watching Mike Peace's video on making your own scrapers. Mike said he cut his nose angle at 45 deg. but that looks to be a sharper angle than on your standard shear scraper. Could I ask what the approximate nose angle is on yours? I realize it has a slight radius so just approximate would be great.
    Thank you,
    Tim

    • @RichardRaffanwoodturning
      @RichardRaffanwoodturning  ปีที่แล้ว +1

      I'd start with the edge skewed about 15°-20° and a bevel of 45°. Ongoing grinding tends to increase the skewed angle and every few months I find myself taking it back towards 20°. You can shear scrape with any scraper, but my preferred size is a 1"x ¼".

    Silly question, but you're operating around the mid-line of the piece , and handle is high when starting?

    • @RichardRaffanwoodturning
      @RichardRaffanwoodturning  ปีที่แล้ว +1

      For shear scraping the tool is tilted up and on edge, so the handle is usually below horizontal. Whereas if you're scraping with a scraper flat on the rest, the important thing is to keep the angle between the surface you're scraping and the top of the tool (or upper bevel with negative rake scrapers) at less than 90 degrees. On a flat surface this means the tool blade is usually tilted down below horizontal.

    Excellent demonstration and info. I've got a couple of cheap skews from when I first started, and no longer use, I'm going to take your advice and turn them into scrapers and make use of them, I like the idea of your usual scraper, and also the spear point.

    • @RichardRaffanwoodturning

      45° on the nose of gouges and round-nose scrapers but steeper on the sides so they are less likely to catch.

    Finally got to it after watching this video last week. I ground a decent cryo m2 steel 1" scraper this morning into a shear scraper and I find it very easy to use now, since shear scraping is a very light touch technique. Great suggestion!

  • @TommyRoberts-s2n

    I have a set of cheap skews and I’ve really got to liking the skew for spindle work, so once I upgrade the current ones will be my shear scrapers! They double as negative take scrapers now quite often 🤣

    Thanks Richard for this overview. I too have been using scrapers a lot more since watching your videos. I know you freehand sharpen these but would you mention the bevel angles once again for us new people. Also does lathe speed come into play when using these tools in shear scraping? Thanks again.

  • @MarklTucson
    @MarklTucson ปีที่แล้ว

    Hi Richard, very useful video however I am still confused about the difference between a shear scraper and a negative rake scraper.

    • @RichardRaffanwoodturning
      @RichardRaffanwoodturning  ปีที่แล้ว

      A negative rake scraper has two bevels, rather like a skew chisel. I regard them as a waste of a good scraper (which has a single bevel). To obtain a negative rake, simply ensure the scraper blade is tilted below horizontal. The angle between the top of the tool and the surface you're turning needs to be less than 90°.
