Hello friends.
This is the official channel of JSK-koubou.
Here you can find many interesting videos about homemade machinery, woodworking projects, plans and life hacks.

I made a sharpening jig that makes the drill bit sharper than new drill.
This jig will be distributed free of charge to those who have purchased a grinder stand plan.

    I hope you will share my videos with your friends!
  • Thank you for inspiring me to do better. While I strive to pay attention to detail and toward achieving a standard of quality in the things I create, it is in the process of making that I try to multitask, to rush through the set up of jigs and fixtures which result in ad-hoc solutions. They serve to solve the need at the time but often not much more. Your Zen-like approach toward creating these tools, and how you incorporate precision and accuracy into every step, is where I want to be. I too would like to see more in the way of dimensions and details, but I understand that this information is what you are selling at your online store. What I would truly like to know is the make and model of the store bought tools that appear in your videos. For example the circular saw used in your wall mounted track saw is often used to cut aluminum as well as other materials. The type of blade and the speed of the saw (RPM) are very important considerations that I believe could be shared without diminishing the sales of the plans. Additionally in this video (5:03) the drill bit / countersink combination used in securing the block to the base was something I have not seen before. I am sure that the manufacturer wouldn't mind being mentioned. Again, thank you!
  • Finally someone that will address basic shop practice. Very good take on bit sharpening. 47 years as an auto mechanic and automotive machinist. I use a different but similar approach, but this jig exemplifies the care to produce the proper geometry to achieve a bit with the proper relief to function properly

    This guy is such a Practical Genius... His love of wood marries technology with simplicity and effectiveness. If there ever was such a thing as Shop-time Machinery and practicing Buddhism and Philosophy while Meditating on Carpentry, this is the only Gentleman that makes me feel like I'm in a Bliss while watching him creating something so superb and simple that this has got to be the new Nirvana Carpentry made in heaven! And I love how clean and neat his hands, fingernails and shop & tools are... A True Craftsmanship and A Gift to YouTubers like me. Thank & Arigato for sharing with us! Much Obliged. just Awesome
  • I wish I knew what my father knew. He was a magician when it came to sharpening, didn't need much in the way of jigs, mostly free hand, including the twisting and a double angle. That was along time ago - 50 years. One time I was doing something as he came home, in a suit white shirt and tie he sharpened my tools to speed up my work. When I got to wood shop I was better than the grade 9 teacher, and I could prove it by dragging a sharpened chisel over a wet paper towel cutting the paper ad the teachers chisel dragged the paper along!
  • Desde Argentina, Ud. es un capo. En cada proyecto que hace. Gracias !!

    Hello dear friend - A sharpening drill is the most complex thing in mechanics! You're using an unconventional system, but one that works. Standards specify precise angles that make a good compromise between sharpening quality and durability. Your drill sharpens well because the countersinking angle (dépouille in French) is very important, more so than the standard 2° for steel. For us, having to sharpen a drill more often is not as much of a problem as it's in industry. That's why I'm going to test your system, because I've been sharpening my drills "hand in the air" for over 50 years. The only drawback is symmetry, which is never perfect. So thank you for the lessons you so kindly provide. Bravo again, you're a master of ingenuity.

    Every time I see you make another tool or jig with the tools and jigs you’ve already made I just cannot help but take my hat of deep to you Sir! They work flawlessly and meticulously. You’re an amazing craftsman!
  • @jca66
    That's pretty cool. I just can't help but think I do a darn good job sharpening bits free hand on a table grinder.
  • @tranpham6151
    This is the best video that I have seen! The cutting edge exactly and right angle compare with original drill bit! Thanks so much .
  • @osnelli
    Your efficiency at work is astonishing, sir
  • @banjerism7281
    So that's how you get the drill out of its packaging!
  • @Heeeeeechan
    切れ子が長く綺麗に切れていますね! 素晴らしい👏
