    That's the best explanation I've seen or heard about proper sharpening of a skew. Sharpening by trying to match the angle is much more difficult. Also, sharpening by hand on the grinder was great!
    Keep up the great work Tomislav!!

    The recommended included angle for a skew is usually 40 degrees, which is almost exactly what you get with the method you used here, and as far as I know most people say the included angle doesn't have to be exact. So, if my math is correct, which is never a sure thing, your method agrees exactly with the usual recommendations but is SO MUCH easier. Thank you, over time you will save me a lot of time and effort. By the way, young man, when you speak of the middle of the twentieth century as a long time ago you make me feel very old.😁

    • @DennisLampret
      @DennisLampret Рік тому +1

      Mathematics is quite correct. Included angle you get from this method is 39 degrees :) this method was taught to me also in carpentry apprenticeship for sharpening chisels. Ratio of 1:2 (thickness:bevel) will result in 30 degrees chisel angle(flat back joiners chisel)

      However, the bevel is not the straight line but it is a curve with the radius of a wheel, so the angle is little bit smaller... Can't calculate exactly as the orientation of the wheel is not known :)

    Dear Tomislav, thank you once again for an exceptional tutorial. The 1,5 to 1 ratio proves to be an excellent guide to grind a skew chisel. It’s the first time in three years that my 25 mm wide by 10 skew works well.

  • @MarklTucson
    @MarklTucson Рік тому +3

    Another interesting video Tomislav. The idea of measuring distance rather than angle makes sense. Doing the math, your 9 mm for 6 mm thickness comes out to an included angle of about 40 degrees (19.47 degrees per side for a total of 38.94 degree included angle), so everything matches with conventional wisdom for skew angles and is a lot easier to measure when grinding. Really intrigued by that forged skew; looking forward to seeing you use it and how it performs.

    Yep. Excellent. I had some help early on shaping and sharpening my skew chisel but had gotten it all screwed up and I wasn't sure how I was going to straighten it out. That is until today. Your explanation cleared up all my questions. Went right out to the shop, set my wolverine jig and started sharpening. Made a little fine adjustment to get the measurement as described. Once I got it right I started the Christmas ornament project you suggested a couple weeks ago. That went very well, knocking out eight of them in no time. Just having a lot of fun. Thanks more than you can know.

    The skew and I have an ongoing love/hate relationship..... I am getting better, but for an old bowl turner, it isn't easy. My first ones were ground back almost 45 degrees from long point to short point. They are much more blunt now, similar to yours. I am trying to figure out if there is any real difference between the ones that are slightly curved like you use, and the straight across ones, which many of the skew masters seem to prefer. I do have one that has a convex grind on it after seeing Eli Avesera use it. I do like it for gentle sweeping curves, but find it more difficult to get a straight cut with it. It is supposed to be more 'user friendly'. Can't wait to see the next video.

  • @1crazypj
    @1crazypj 9 місяців тому +1

    Are those tools actually high speed steel or high carbon steel?
    High speed steels (HSS) are generally used for metal turning or shaping/milling and will cut hardened and tempered carbon steels.
    Looking at the label, is it 304-300 hardenable stainless steel?
    I have a large HSS parting off blade from a big metal lathe that I was planning on re-shaping to use on a wood lathe but skew looks a bit scary when it isn't held in a tool-post mount (I trained as a precision machinist in mid 1970's, 5 micron tolerances)
    Ratio of bevel to thickness is a great way to remember sharpening angle, thanks for the tip 1.5:1, I see at 11:25 the skew is HSS, cool.
    HSS retains hardness when red hot so you won't change steel structure if it's blued.
    I like how you switch from metric to inches, at one time a lot of Europeans could do the same. I guess you have to be a 'minimum age' to have learned it?
    It takes a lot of skill to show things going wrong, when skew catches I'm sure it can be very dangerous for a beginner to lose control?

    • @tomislavtomasicwoodturning
      @tomislavtomasicwoodturning  8 місяців тому +1

      Thank you sir,
      I have meet few metal turners and they usually are afraid of using wood lathes, beacuse of that tool mount, but accually I would say its easier on wood, but you already have a big knowledge that only needs to transfer to wood and its specific problems.
      😅 Not sure about the age but I learned a few "standard" Imperial measures so I can explain better.... Well that was idea at least 😉

    Oh, I like skews. So simple and efficient. I put more angle on my edge, as in the distance between long and short points is greater, and a radius beyond the first 3mm is helpful.
    One of my mentors uses the style you demonstrated, gives it an even more exaggerated tip distance and he sharpens to stropping. He is an artist with skill rivalling Cindy Drosda. That's not his production skew. It's a neat style, and not too much of a learning curve (because of the conical shaft I found it just a bit grabby). What I didn't care for was the handle style. I imagine you could put whatever style you choose, but the traditional style, the one you used, is not my favourite.
    Loved the preview. I think each new catch is less scary than the last. Tell new turners to just cause 100 catches and get that out of the way. Obviously I'm joking. I remember the frustration of catches and not knowing what I did to cause them. It's nice that they happen way less, and don't bother me unless it's that final cut that wrecked my form. :)
