    What was the outside diameter?

    OD can be anything from 2.5"-3" as long as both pulleys have the same OD.

    I also just test the direct connect method and dB reading just the motor shaft. Unmounted (so it could be causing vibrations) it goes from an ambient 60dB to 77ish. So the motor itself creates 17dB. Direct connecting it was much quieter at ~80dB ish. The bearings do definitely make some noise though. I'm not sure if they just need time to be run in or if the preload is incorrect. I'm banking on that because I just noticed a very slight bit of both axial and radial play. That shoots red flags to me that there isn't enough preload because I don't see how else a brand new bearing set that has press fit fitment would allow movement. But I also don't have a tool or know what tools to get to really crank down the preload nut. My makeshift one must not be cutting it. Or the preload nut is just garbage and doesn't work well for whatever reason. It's cranked as well as I can get it with my tool.

    You need a spanner wrench. Here is what it would look like. This one was made by a G0704 owner who also needed to set the preload. https://grabcad.com/library/g0704-spindle-pin-spanner-1

    Yep, definitely need to adjust the bearings. I also used the tapered bearings. They work well and mine are quiet.

    The nut is absolutely a crap design. Here is a guy that made his own.

    I have one of these that I used on mine.

    I have a makeshift one, his is a lot nicer though lol. I may be able to weld some scrap together to make one more like his out of steel. I also saw that preload nut video a long time ago (and just watched it again like an hour ago) and that one is so much nicer. I just don't have a lathe to make it on lol.

    I was just looking at the VM25 users manual and on page 26 is the head diagram. Do you still have part # 206 installed? If you are no longer using the quill can you remove this and eliminate it's noise as well?

    EDIT: I just looked at your video again. Yes, I see the gaping hole in the top. Those parts are not there. OK. Time for me to get some shuteye.

    I ordered a couple different spanners so hopefully that helps me out. I swear I looked on Amazon for some adjustable ones before but didn't find anything. Apparently I didn't...

    Make a spanner out of a crescent wrench, it works fantastic. An 8" or 10" crescent wrench from HF is just a few dollars.

    This is exactly what I built years ago. Still have it and it works great.

    I love that crescent spanner. Great idea.

    If you think it is really an aluminum pulley that you need to solve the problem, send me a drawing of what you want it to look like. I won't be at my shop until Thursday, but I may be able to turn one for you.

    @CL_MotorTech That's a great idea, it would likely have a lot more leverage than an actual spanner too. Have you every had any issues with the screws bending? My makeshift one I used some scrap aluminum that I bent two sides out like a fork, drilled and tapped two holes and put SST socket head screws through. It seems like the screws bend more easily than the aluminum though in my experience.

    @maxspongebob Let me see how it goes getting me preload correct first. I'm sure the final solution will end up involving pulleys that are aluminum but I'll just have to see first. That's a very generous offer and if I need a set I'm willing to pay.

    If that is the case then I would say that is a likely culprit. Attaching only to the spline shaft means that as the spindle rotates, belt tension is pulling on that shaft. There will be flex on the shaft and it will move in the internal spline and make a bunch of racket.
