    I usually do mine by hand on a progression of stones, then strop on a progression of compounds, from 15 to 9/4/1 micron. Very time consuming. Anyways, Happy 60th birthday mate! Make it a good one!

    You could step it with spacers on the jig shaft with something like a air hose. But I do like the adjustment to the handle. Early stages at the mo

    I think your on to it. It's not your best work but that's what trying new things is about, their is a learning curve that I am sure you will evolve, change and eventually master. TBH I didn't think you could get a convex edge off a round wheel, but I'm convinced you absolutely can. I used ceramic flat whetstones and sharpen by hand. With all my stones, sink bridge flattening stones, natural whetstones I'm probably into it for the cost of a Tormec 😅. And while I can get very nice edges I've spent many hours developing the skills to do so and compared to the best Japanese hand sharpeners I'm probably a 4/10. But I find it very relaxing and enjoyable. When I build my new shed I might include a T8 section. I think a Tormec is really only as good as the person behind the wheel, it requires skill to sharpen well with one.

      It's unwise to compare yourself to other humans. You enjoy sharpening just as much as I do. The knife doesn't care who's sharpening it or how they do it. It just wants to be sharp. I know someone who has an entire book stand full of expensive japanese stones. Probably well over $50,000 worth, more like 80,000 worth. If he hears about a new stone he buys it. If he hears about a better stone he buys it. He probably has all the stones in the galaxy. It's his hobby and he loves it. He's probably a 4/10 as well but he doesn't care. He's also fascinated with the Tormek and wants to buy one of those too.
      Other people spend $500,000 on a drag car or a boat. Or on whisky, women and whinging. We're better off. We have a nice clean wholesome hobby/interest/home business. I'm good with our spending. I blew $300,000 on the stock market one month. It's all relative and today I turned 60 and have yet to grow up. Not even close.
      We're good.

      Well said. I personally don't know anyone that is into Japanese whetstones and sharpening like I am. I'd love to check out your mates stones, there's something about the feedback or feel of a great stone that is hard to explain, you find yourself endlessly chasing that perfect whetstone. I get it! Knife sharpening & restoring Australian made striking tools is another hobby. I have over 50 axes, about 20 sledgehammers, many shovels, picks, mattocks. Brands like Hytest, Plumb, HB, Cyclone, Keech, Halts Bruk. All that old vintage steel. Hafting new handles, using the drawknife to haft & make new handles by hand. All that good stuff.

    Amazing. Still trying to get my brain around what your doing to achieve convexity but I can see how it would work. Next your going to tell us how to sharpen a serrated bread knife on a Tormec wheel.

    Ok this concept is really elegant, well done!
    I feel like my inner mechanical engineer wants to solve the "problem" of longer travel so it actually covers the entire bevel and smoother oscillation. Any plans to modify a jig for this?

    • @iSharpen
      @iSharpen  2 หลายเดือนก่อน

      There's no call for it really. I was just playing to prove to a Facebook troll that it could be done. But some sort of mechanism to extend the travel would be interesting. Although you can't go much higher up the knife (lower down the wheel) because the jig will hit the wheel.

    My Sanelli kitchen knives are soft, thin and sharpened that way. They are made in X50CroMo14 and I like it at all. As long as they are "new" they are OK, but directly as they need sharpening they start wearing out constantly...

    • @iSharpen
      @iSharpen  2 หลายเดือนก่อน

      X50 knives are very common and I like and use them. If your knife is going blunt too quickly it's probably not the steel but the way it's sharpened. Outdoors55 took a $1 knife, sharpened it properly, chopped wood with it for 30 minutes straight and it was still hair popping sharp. How can that be? It's all about the geometry of the sharpen and how the edge is prepared. Most critical is the removal of all burr and burr remnants such as the root (wire edge). Dr Vadim from Knife Grinders Australia wrote a white paper on this topic too. Your knives should be lasting a long time. If they're not, you might want to look into the burr issue.

      @@iSharpen No matter how I try I don't get good result on the T-8 with them. Just 1,5mm thick on the back and soft, aim for 30° (15°+15°) but get much better results with harder knives. Maybe a belt sander like (Ken Onion) Work Sharp could be better for me for them, love the T-8 for all others from axes to planer blades 👍🏼.

    Tormek uses the same up and down method for convex edges on axes in their new AX-40 video. As they did in their video on the new KH-45 jig.
    Not surprisingly, in one of their earlier videos, Wolfgang demonstrated the varied stop method for achieving convex edges. I think the latter is preferable than this up-down grind method. About the same rough result.

      @@iSharpen Yes, he did. I just finished putting a convex bevel on a machete using the 2 stop method (raising the support bar 2 stops) to shape the apex. There are no discernable grinding lines. It didn't take much time using different grits for each angle on both sides of the blade. Ah, the enjoyment of learning and accomplishment!
