When the motor was removed, it was put on the floor beside the mill & visually examined. It turned very smoothly, no bearing noise, no scratchiness. No axial play. No rotational play like in a key seat holding the sheave steady. The sheave plus (now compressed) bottom spring assembly is still...

Yes, been to the bottom of the head. I haven't done a detailed writeup yet but some picture samples. The loose-'ish' bearing I was referring to is within this gear shaft assembly. It was pressed out & replaced & the minor looseness fully eliminated. All bearings replaced even though they felt...

> do you have an iPhone or an android? Strange as it may appear, Apple. I'm not a power user. Its familiarity laziness syndrome. >A very inexpensive "usable in a pinch" stethoscope is simply a thin dowel of wood yes that's what I was referring to with the 'screwdriver test'. Metal blade on...

And then of course there is the arguably more useful grind-yer-own from HSS so you can do Innies & Outies with the same tool

Cool project. Keep us posted on your build!

I haven't got that far, hence this post wondering out loud about source electrical. My gut says mechanical but ignorance can lead one down all kinds of paths LOL I'll check out some apps, that also sounds useful for some other of Life's Puzzles

Removing the vent panel exposes some of the variable speed Vee belt & some of the drive cog belt beneath that. Not the greatest visibility but it would be interesting to watch the belt in 'freeze frame' to see if it did anything funky coincidental to the resonance noise. You are saying I would...

~2019 when machine was new I had what I thought were centrifugal switch issues. After about 500 starts it would go into what sounded like heavy cogging mode. I fiddled with CS position, confirmed the springs & counterweights were operating correctly, everything locked down, new switch, cleaned...

No VFD. Although there is constant pressure from certain 3-phase/VFD 'pushers' to convert LOL. Its a single phase 220V, plate attached.

Hmmm... interesting, @Johnwa I actually thought about a strobe to try & see if I could capture a resonating belt flapping or sheave spring wobble... to kind of freeze the action so to speak when I heard the resonance. My only exposure to strobes was like car timing where it was triggered off...
