    Hey Everyone,

    New to the forum but been reading lot's of posts. I am wanting to build a 2x72 belt grinder as I am starting to get into the knife making hobby. I started to learn on knife blanks purchased and did my own handles but life got in the way and I was unable to go any further. Now that things have settled down, I am able to start up again but I don't want to buy knife blanks anymore. I want to make my own :)

    I saw ETremblay253 had a great design but that topic is a few years old now.

    Could I get any advice from you guys/gals on some nice designs/plans that I can use?

    I have access to waterjet, Laser cutting and a buddy of mine has a CNC Mill and Lathe so machining isn't a problem. I really like the double plate design with spacers.

    Would like it to tilt
    2 arms for sure
    Using 1.5HP 3PH C-Face motor and VFD

    Thanks everyone!

    Dezi

    Hi Dezi,

    I have made a few grinders in the past. I designed and built the Sayber OSG in 2017 and that is my main machine. I posted some details here. https://www.canadianknifemaker.ca/index.php?threads/new-2-x-72-grinder-build.2791/
    The parts were waterjetted from 3/8" steel. No welding, all bolted, drilled & tapped. It runs smooth and is fairly flexible with some added attachments like the 10" contact wheel and small wheel tool arm.

    Hey Dan,
    Plan to use some of your design. I’ve already read about 70% of your blogs. Love your site. Soooooooooo much information. A big thank you for doing that.
    Plan to model it up in solidworks and will post as I progress. Thanks again

    You know Dan, looking at your build and drawings, there really is no reason to re create it :) you did a really nice job. I've been bored sitting around the house and have lot's of time on my hands so I was thinking of designing a new grinder. Maybe we can all work together and make a new design? Or not.. Just thought I would put this out there.

    Dezi,

    I am doing the same thing as it's too cold to work in the shop. Dipping down to -40 overnight most of this week.

    The new one is a horizontal unit with small wheel holder and 4" rubber contact, plus about 13" of flat platen mounted on a single piece of 1/4" hot rolled.

    Was also thinking of a 3 idler attachment. I would love 2", 3" and 4" contact wheel on one tool arm.
