    Hey Rob, I believe on the volume settings for your videos over the last couple weeks it's been really low during demonstrations or teaching part etc, or rather the actual new footage part. But in the pre-recorded bits like where you say "If you like my style of teaching" it's much louder.
    Might want to have volume or video gain or whatever its called checked because I'll tell ya if you're wearing ear buds you're in for a surprise of volume difference.
    Anywho, great tips on that saw holder with the hinge and stuff. This will definitely be my next project. Thanks again for the years of teaching, videos and all that you do for others.

    I love the guide on the end of the file. I have been sharpening for a number of years now, I wish I had that one when I started. Thanks for the great content of your videos. Keep it up. As a veteran, I thank you for the wonderful work you do for my brother veterans. God Bless.

    Jason at Fireball Tool did a comprehensive test with files showing the amount of damage in dragging the file backward after making a cut. Interesting results. Negligible damage in 2500 strokes. Personally, like you, I like the control of using the back stroke as well as the benefit on a saw blade of removing micro-burrs that occur with one direction cuts.

    OMG now I see my first mistake I used to have my file off to an angle instead of what you are doing straight across so it looks like I should be sharpening the points and not the sides of each tooth thanks Rob. I'm going to use the oldest saw for practicing on

    • @RobCosmanWoodworking
      @RobCosmanWoodworking  2 ปีที่แล้ว

      If its a rip saw you file perpendicular to the tooth. On a crosscut saw you file at an angle (Video coming soon on a crosscut saw sharpening). You should be sharpening or removing metal from the whole front of one tooth and the whole back of the other tooth that the file is touching....not just the tip of the tooth.

    If you run the sharpie from the handle to the tip, it does less damage to the sharpie and is easier to mark the teeth.

    Another great video Rob. Thanks for sharing. I have a whole bunch of old carpenters crosscut and rip saws from my Grandfather and would love to get them sharpened up and usable again and not just an ornament in my shop. Would love to see your video of refurbishing an old saw like that. I know it is not something for dovetails and fine joinery, but pretty sure you would make a great instructional video.

    • @RobCosmanWoodworking
      @RobCosmanWoodworking  2 ปีที่แล้ว

      Depending on how rough shape they are in they will need tobe jointed, possibly some teeth reshaped, and possibly re-set. We have that on our video to do list but it will be a while

  • @bigoldgrizzly
    @bigoldgrizzly 2 ปีที่แล้ว +1

    I do fall back on cheap hardpoint saws when there is risk of hitting into nails, grit or other hard objects. These saws can also be quite easily re-sharpened using diamond files which helps salve my conscience for buying disposable tools.

    How do you tell if your saw is premium or disposable hardened? I have one old saw that was my father's, and a new one I bought at Home Depot 2 years ago for not very much money.

      @RobCosmanWoodworking Hmm, ok. My Irwin saw is probably hardened then. I had been using my dad's old, worn, rip saw, forever, and then I bought the new Erwin crosscut saw for $30 and it cut through wood like a hot knife through butter. I was amazed! Would love to see dad's old saw perform like that.

    Great class. Pardon a stupid question: can I resharpen a Japanese saw?

    • @RobCosmanWoodworking
      @RobCosmanWoodworking  2 ปีที่แล้ว +1

      Well if it's an inexpensive one it's likely harden teeth and that blade is designed to be used and thrown away. If it's a expensive traditional Japanese saw it can be re-sharpened but it takes special saw files and is much more difficult to do. Saw sharpeners apprentice for 7 years in Japan to become master saw sharpeners.

    I didn’t quite catch the difference with the tiny front teeth. These have a different rake right? They’re angled backwards a little. Can you just confirm that you rotate the file backwards a little to account for this? I couldn’t be sure from the video. Thanks!
