    I just did a search in the posts, and it seems that Nexus Grinders has an account here, but there haven't been any posts with the account, as of yet. Last week, I stumbled across Nexus Grinders on Facebook, and will finally be grabbing a 2x72 for myself, after so many years of not being able to afford one. I mean, under $700 bucks for a grindert hat is made in Canada, I'm in!! Hopefully he will start posting here, and we can all stop ordering grinders from the USA!!

    Just thought I would let everyone know, because I know how hard it can be, to source this stuff in Canada! So hopefully, @Nexus Grinders will fill the void we have been missing in the great white north!!

    Oh, and how's everyone been?! I haven't been around !icy over the last couple years. My rheumatoid arthritis has really kicked my ass I the last little while. Once I have a grinder that isn't a dime store 1x30, I can start posting photos! I have only been able to make a few over the last year, but being broke, and on a really limited income, I have finally amassed just about everything I need to start doing some decent blade work. I am also thinking of starting to make micarta. My boys are at an age now where I can show them how to start making knives too, before I am completely screwed, and unable to walk or use my hands! Hahaha! Hope everyone has been well!!

    Have one on the way, I ordered it Tuesday night and shipping to Ontario was $87.33 via Canada Post.

    The reason this unit won me over is the Nexus 2 Axis tracking mechanism which will allow me to run my machine in reverse without the belts slipping off the tracking wheel. I was waiting to receive my grinder before posting about it, but I am really excited as the only other grinder to have a 2 axis system for reverse grinding that I know of is the Reeder grinder. The big win for sure is that this is a Canadian company!

    Here is a link to the video on the tracking mechanism

    https://nexusgrinders.ca/image-and-video-gallery/

    Also I would like to give a shout out to this company

    https://www.emotorsdirect.ca/

    The above is where I got my motor for this grinder. $25 flat rate shipping in Canada. I ordered Tuesday and I got it last night!
    I picked up a 2HP 3600RPM 3 Phase WEG C face (to bolt directly onto my Nexus NG-3) for $304.00 plus tax and the shipping. My KBAC-27D will be hooked up to it and I should be in business...well...once I finish the garage’s grinding room...last thing to be done.

    I will try to post images of the complete set-up before my garage is finished, otherwise it will be May before I post lol!

    Long time no see Shad. Hope you get some time in the shop. It's totally therapeutic!

    Don't forget Jo McKenna @ Vashti Tactical in BC. @ConnorBC He's been offering reasonable grinder and accessories for a few years now. I suspect his designs are in the Nexus but I can't be certain.

    @dancom

    I noticed the platen design and recognized it as being very much like the ones found on @ConnorBC ’s grinders. Jo and yourself are both acknowledged in the ‘About us,’ section. I was hoping Jo was apart of this business, you may not recall but several times I jokingly harassed Jo on the forum about when the hell his website would be up and running!

    I understand that Vashti Tactical has/had a Facebook page at one point, but after a year of looking at grinders online and contemplating a purchase of the Reeder grinder that would have cost me several thousand dollars with the cost of said grinder in U.S dollars, shipping, import fees, taxes etc. etc. was all said and done, I finally settled on the Nexus because it’s looks great, it has a feature I am very excited to use (mentioned above) and the important factor that they had a professional website up and running with PayPal... and that’s how I like to shop online. I would have been more than happy, as I said on several occasions here, to buy one of Jo’s grinders if I could have gotten one of his the same way.

    Here’s hoping he was involved somehow.

    Thanks man! I've got a bunch of damage from it, so my joints are always sore, and there's nerve damage in my feet, so they always have pins and needles, and burn like hell. But it could be worse. I'm not at a point where I've got any deformities from it yet, and hopefully it won't get to that point, but it's always a possibility down the road. Luckily, I only have to walk with a cane every now and then, but even driving is getting harder to do. As for Vashti Tactical, I didn't even realize! I will check into that. Google searches don't bring much up when trying to find Canadian anything, in the knifek making realm.


    For sure @dancom ! Long time no see. And I gotta agree with you on the hobby being therapy. I love doing it, but it I find myself screaming at the 1x30 more often than not! Last summer, I final!y got myself a decent little workbench built with my 2 teen boys, also got the vise that @Grouch was awesome enough to hook me up with back in Winnipeg, and things are set up in the small shed that I got with the house we moved into in Medicine Hat! I just need a dedent grinder! I've also been trying to get away from technology a bit, and it's harder to sit at the computer more and more, but I try to do what I can! I still follow your website though! I've wound up at your website on countless occasions, being directed there from other articles, Google, and YouTube lol.


    It sucks, and I've been trying like hell to finally get a decent grinder that isn't going to cost me a good chunk of my yearly disability income haha! I've only made one knife, with myself actually doing minimal grinding on it, as a friend was showing me how it was all done and such, and a couple small ones, that aren't really usable for much other than box cutting. The big thing is, is I'm very artistically inclined, and have a knack when it comes to grinding knives for some reason haha, but the 1x30 isn't very versatile, and I just can't get enough out of it, and use it to the best of my ability lol. It also doesn't help that I'm 6'4 and 230 pounds, with massive hands. Everything is small to me, and I need something bigger. I tried making a larger knife this summer and just didn't have enough belt, or power in the 1x30. Couldn't get any real plunge lines and the machine itself is rather UN-precise hahaha! It always seems though, that something has always come up with the finance department, when I get my tax return, so I get screwed. Last year it was a bunch of bills and the kids magically needed a whole new wardrobe worth of clothes, and everyone magically burned through their shoes at that time! The year before it was a damned washer and dryer set. So I told my wife that I don't give a crap! This year my grinder is being purchased, whether we had the cash or not. I've got orders lined up, but no way to produce the large stuff that friends want. So this year is MY year!! I'm coming today for once!! NO IFS, ANDS, OR BUTS!! It's all ME ME ME this year! At least this way, I can try to make some extra cash for the family. It's been weighing on me rather heavily, not being able to provide for my wife and kids, almost to the point of depression. So that's why I'm doing it this spring. It's at a point now that I NEED to do it.

    I like it! Bolted my WEG 2HP 3 Phase to it and soon (once I can finish the grinding room) I’ll hook up the KBAC-27D and I’ll be in business to make something again lol

    Sweet! I like the way the tracking wheel can be adjusted on two planes.

    Dan, do you think the tilt stand (CAD) you designed would work here?

    Griff,

    The Sayber hinge works around the centre of gravity of the motor and is integrated into the frame. Not sure if that would work well for this application.

    One approach is to make a hinged table like the Wilmont TAG. This is the easiest method, but has two drawbacks. Firstly it needs to have a hole in the table to improve airflow to the motor when in the horizontal position. Secondly, because the hinge is on the left side of the motor, the belt is much higher off the ground in the horizontal position.

    Another approach is to hinge the grinder base and hang the motor off the back of the bench or stand. This requires a short workbench or purpose-built stand, but the motor has all the air it needs and the belt work area will be about the same height in vertical and horizontal positions.

    Yet another approach is to make a stand that hinges the base of the grinder. The stand will have to be at least as tall as the motor is long plus a couple of inches for airflow. This will raise the height of the grinder significantly, so a purpose-built stand will be needed.

    For reference, my stand for the Sayber is made from an old Black & Decker Workmate and is about 21" off the ground.

    And, it's tactical black. So you can make knives stealthily. : )

    @dancom Thanks Dan. I have only just recently built a very crude tilt stand for my original grinder the AMK72. This grinder was not made with the intention of ever being tilted lol...the company actual sells a stand alone purpose built horizontal grinder to emphasize that point!

    I Frankenstein’d together pillow blocks, wood, angled steel, L shaped brackets etc etc to get this beast to tilt :D.

    I was really hoping you’d reply, ‘Why yes it would work,’ lol, but okay, back to the old laboratory, “Come Igor!”

    [​IMG] Video of the first run of my Nexas Grinder and subsequently the first run of the KBAC-27D. Was so happy I didn’t mess the electrical up and end up with spiked smouldering hair! Though some might say it would be an improved look!:D

    Hey @Griff What size motor are you running, on it? I'm only set up to run a single phase motor, and I'm debating if I want to get the c-face motor style grinder, or the other style, and run a pulley set up. The pulley setup might not be feasible, as I'm not sure what kind of space the grinder takes up, and I'm not sure if my work area is deep enough to run that setup, so a c-face model will likely be the way for me to go.

    Dammit! That isnt gonna work. I think I will just go the route of a treadmill motor for now then. @Griff was that motor and VFD together? I would love a variable speed controled set up, and it looks like single phase motors with a VFD are a bit harder to get than a 3 phase. I'm sure I can find a treadmill on the Facebook marketplace for dirt cheap, or even free. I'm just not sure what size motors or what style motors that they typically use in them. If I use a motor with pulley setup, how much room do I need? I was looking for a simpler way to set things up, but Sure Mak isn't producing their grinders anymore. I fell in love with theirs, when I met a friend, who owns one, and he taught me a thing or 2 on it.

    Maybe @dancom or @John Noon or @ToddR or @Grouch or someone else knows a way I can rig things up!!

    Hi Kevin,


    With the countershaft design plan for about 2 square feet for motor, sheaves and belt.

    Single phase induction motors are not speed adjustable. Smaller motors like shaded pole (think bathroom fan) can be varied in speed but these are useless for grinders. For speed control, three phase motors require variable frequency (a VFD) and DC motors like common treadmill motors require variable voltage.

    Although far from ideal, you can source a treadmill motor and DC speed controller and figure out a way to attach a sheave (pulley) to the motor. A few treadmill motors have standard shafts, however most have an odd size (15 mm) diameter and no keyway to lock the sheave on with. They also have a large flywheel which is needed for cooling the motor and it has a left hand thread. I have found one way to secure a sheave to the flywheel as shown in the video.



    Over the years, I have helped a bunch of people setup treadmill motors on grinders and presently zero of them are still in use. Reasons?
    • Poor recovery under load. Motors are slow to recover if you push them a little hard.
    • Brushes fried. Yes these are DC permanent magnet motors. Changing motor direction seems to agitate the brushes.
    • Flywheel kept coming off in reverse. (that could be fixed with a tack weld)
    • Motor burned up from too much junk getting inside. Open motor is not ideal for a grinder.
    • Motor constantly overheating because they didn't use the flywheel.
    • Controllers failed. More than one of these.
    Eventually each ended up acquiring a proper industrial AC motor.

    The #1 question I get is how to mount the treadmill motor on a grinder that requires as NEMA C face motor. Many grinder designs require such a motor; Reeder, Sayber OSG, Wilmont TAG, NorthRidge Tool etc. The answer to the C face question is "don't" as you have to take the flywheel off for this application and the motor overheats. There are a few designs like the KMG, AMK, BG-272, Vashti Tactical and I think Nexus has one that the motor mounts on its foot mount (model NG2) to the base of the grinder or bench top.

    I use my treadmill motor on my lathe which is in a fairly clean environment and it's still running, knock on wood. These motors are not industrial which is what a belt grinder application is.

    My personal recommendation is to start with a TEFC (sealed) single phase induction motor (fixed speed). When you can, upgrade to a three phase motor and VFD. The single phase motor can be put to use on another project after retiring.

    Dan
