    Hey all! I've been making knives for quite a while now, and I've finally saved up the money to upgrade from hand files to a 2x72 Belt Grinder. And now I'm trying to decide between two different grinders. The Vashti H2S and the Nexus NG-3. They both look like amazing pieces of equipment which is making the decision quite hard.
    I would really like some input from people that have owned and or used either of these grinders, and can speak to their performance, ease of use, and craftsmanship. The price difference is about $150 more for the Vashti.
    Thanks in advance everyone!

    Okay, but consider your motor and vfd options too. Factor in those additional costs first. You may find you need that $150.

    I am very happy with my Nexus. But you have to understand it’s not a case of which is better. Both companies are Canadian and provide a solid chassis, and more importantly the standard 1.5” tooling arms slots so you can buy whatever from wherever you want when upgrading.

    Scroll through the above thread and you’ll see my Nexus in there and my Motor and VFD, along with where I got them a few years back. The Nexus being my second grinder I was very careful choosing it and what I hooked it up to.

    Two Pro’s I can tell you off the bat on the Nexus

    1: A motor will bolt directly onto the Nexus. You would have to upgrade to the more expensive Vashti’s for that.

    2: It has a dual-axis adjustment tracking wheel for running the grinder in reverse.

    Hey! Thanks for the response Griff!
    The motor being able to directly mount to the grinder is definitely a big plus for Nexus. In what situations would it be helpful to run the machine in reverse?

    Sharpening on the grinder. In conjunction with a vfd you can slow the belt right down (this doesn’t throw sparks into your face lol).

    Ohhh, that makes a lot of sense. I didn't even think about that.
    Do you find any bad vibration when using the machine? Or is it pretty solid?
    And are there any to things about the machine you don't like?

    Nothing I don’t like. It’s a solidly welded, 3 tool arm, steel chassis.

    It’s priced right for what you are getting, there’s nothing more or less to say about it.

    It’s key you understand you’re paying only $735.00 Canadian! There’s only one bell and one whistle over other grinders, and it’s that dual axis tracking wheel. Theres only one other grinder it’s on I think, and that’s the Reeder Products grinder out of the U.S.

    If I were doing it over again this year... I might have gone with Vashti’s ‘Rise,’ DIY grinder because it looks like it comes with the tilt option for $1700 w/ aluminum wheels.

    The convenience of going vertical to horizontal is as revolutionary as going from a single speed motor to a VFD in my opinion.

    Wuatt, if you’re on the fence, keep saving. That’s solid advice. If you want more you’ll have to spend more. Same with everything.

    Good luck with your decision man:beer::beer:

    I was trying to make the same decision a few months back between the same 2 grinders. I never did buy either and just stuck with my sketchy homemade wood one for now.

    But my deciding factor between the two would have been if I wanted horizontal or not.
    If you don't think you need horizontal then the nexus is likely the better cheaper option. If you want to spend an extra $280 to get the horizontal tilt base with the H2S, then that's probably the better choice. (the tilt base also allows direct mounting to the base)

    I turned my Old grinder into my horizontal. It’s definitely a big plus if you only have one grinder.

    Joel I’m looking at the H2S again, I can’t see where you’d be able to do a direct mount...maybe I am missing something in the photos? It’s just a double stacked two tube frame.


    Edit: Never mind I see what you meant as the motor will bolt directly to the tilt stand they sell.

    Nice one, good catch Joel! :beer::beer:

    Thanks man, I appreciate that advice. I considered the Rise but my welding skills are pretty mediocre at best, lol. But I'm getting my shop wired for 240v right now too, so I'll probably just save for a while and see what happens by the summer!

    Yeah, that tilt base was one of the things selling me on the H2S over the Nexus. But $280 on-top if the initial cost is a bit steep for me.

    @Wuatt pretty sure the Rift DIY is bolt together. They’ve welded and tapped everything. I would double check.

    Yeah it really all depends. I still haven’t decided if horizontal is worth it for myself. If it speeds up or simplifies your making process, then over time it should pay for itself.

    Thank you for supporting Canadian business. From a design perspective, (having designed a few grinders) would take the Nexus, as Griff mentioned the motor mounts to the frame reducing vibration and alignment issues. There's also a lot of more mass there with steel plated vs. 1/8" wall HSS tubing. I am not a fan of how much gap there is between the tool arm and the receiver in the H2S. That should be nice and close. I made my first grinder from 1/4" wall HSS and my second grinder was from 3/8" plate similar to the NG-3. A world of difference. The mass absorbs vibrations. This is why heavy-duty shop machines have slabs of steel and 300 pound bases.


    I use my Sayber OSG horizontally about 10% of the time, otherwise mostly vertical.

    EDIT: To be fair I have a dedicated horizontal grinder now, so the horizontal mode gets used mostly for the surfacing grinder attachment.

    I took into consideration all the comments and suggestions that everyone posted, which made my decision a hell of a lot easier, and was much appreciated. Being Canadian I knew from the start that I wanted to buy a grinder made in Canada in order to help support a Canadian company. And after a lot of thinking I decided that I'm going to purchase the Nexus NG-3 because of the ability to mount the motor directly to the machine, as well as the heavier chassis to reduce vibrations.

    I also spent some time designing a stand to mount it to with the ability to rotate the grinder from vertical to horizontal easily. Ill take pictures and write up the details so that if the idea hopefully works out I can share it for anyone else trying to do the same thing!

    Thanks again for the advice everyone!

    Really good. I think you will be impressed with how sturdy it is.

    I'd definitely be interested in that stand!
