    That tip to put the tap handle into the drill press to keep it lined up is pure gold!

    Great tool idea to jump off from. Maybe forge out some spring clips for the side pieces instead of rubber bands? Sliding dovetail for the bottom sanding form instead of screws, so smooth and even all of the way instead of spaces left under the sand paper at the screws? Love the various sizes idea, could be useful to adapt as needed for woodworking and refinishing antique furniture too. Thanks for sharing this with us.

    I’m very late to the game. My sons want to build knives. I’m more into jewelry and small sculptures. In jewelry, you make a lot of your own tools because commercial tools are very expensive and those one-off wonders can cost! So making your own tools, customized tools makes real sense. I’ve discovered that I enjoy making the tools as much as making the jewelry, lol. It engages my aging brain and should be beneficial for my sons. One is 39, the other 42. One is disabled and can’t do heavy manual labor anymore. The other is a talented graphic designer whose boss wrecked the company during COVID-19. His job evaporated. But they’re into making blades and I have a tiny shop that we can work from. I inherited my grandfather’s anvil and small forge. I can help update the tool selection to better quality tools. I need them for my sculpture work. I’m disabled and retired and bored to pieces. I look forward to watching all of us better our skills!

    Haven't seen your work for awhile, and this morning here you are! This is a cool idea that looks like something I can use in woodworking! As usual, I enjoyed your humor and your presentation. Funny, I don't have 3 hands either! Doesn't do much good for me to complain about it! But it is reality, and working alone it often comes up. Enjoyed.

    Just an idea...
    Instead of semi-round clampy-thingies you can try with pipes of the same material and bungee cord that goes trough them.

    • @valinn13
      @valinn13 5 місяців тому +1

      I had the exact same idea. Just drill out the poly rods and run some elastic cord through them and tie it off. Then it doesn't matter if the clamping rods rotate as you move the sandpaper.

    I think I would adhere a layer of sheet rubber or gasket material to the top surface of the off-hand rest. Just to make sure your hand doesn't slip off.

    I think I could make one of these. I don’t have any of those fancy machines, but I have a saw, a file, a hand drill, some sandpaper, a rubber band ...

    European blades only very rarely had forged in fullers. The blade profiles and fillers were often scraped in. This can be seen in period artwork

  • @xj9779
    @xj9779 5 років тому

    Great idea... Hmm that clamping rods should have a bit longer and groves on both sides and two rubber bands clamping it to the aluminum block. So you just need to pull the used sandpaper bit for bit trough.

  • @mikewilson8265
    @mikewilson8265 5 років тому

    Great idea and a good looking tool. I would try rubber O rings instead of rubber bands. I have used them and neoprene O rings with a lot of success in similar circumstances. Thank you for your always interesting presentations.

    Besides files and small contact wheels on a belt sander, any tips for creating serrations? Ive messed around with veff type serrations as i find theyre easier to add.

  • @barthanes1

    Make the sandpaper keeper dowels stick out of the end of a small clamp like this ( >= ). That way you can clamp it on the tool from the front without fiddling so much.

    Why not use diamond abrasive? Chop saw up round files in various grits. That's how I shape hard to reach curves.

    Wouldn’t it be easier to control if the handle was perpendicular to the direction of the fuller? Imagine a d-shaped bracket holding the handle similar to spades have.

    Your "three hand" tapping technique can be easily avoided. Just put the tap into the chuck, but don't tighten it too much, this will allow it to spin when it bottoms out. The tap body is hard enough that it isn't damaged, and smooth enough that the chuck jaws are not damaged. Put the mill in a low r.p.m. and you can power tap. Much easier than growing an extra arm.

    If i wanted to make a knife that would come in contact with metal alot what metal would i use so the metal wouldn’t dull when i cut metal with it?

  • @shanek6582
    @shanek6582 5 років тому

    Would different grits of lapping compound and a steel rod sand a fuller easier than sandpaper? Im assuming it must not work or you’d be doing it already but seems plausible.

  • @vdub5818

    I have a spring loaded tap guide that centers onto a tap wrench like you used the tap at 6:30. Keeps it perfectly centered and gives it the pressure needed to drive the tap forward.
    Literally worth it's weight in gold when tapping mokuti or titanium bolsters for hidden hardware with 2-56's.
