Something interesting happened with my ol' Craftsman block grinder

[Hickory n Steel]

About 10 years ago a family friend scored me a 1958 Craftsman 1/4hp block grinder from the repair shop on the farm he works at when they got a new one.
I've used the crap out of it ever since, and recently the switch went out.
Wile I was replacing that switch and putting a more suitable cord on it I figured I might as well replace the bearings because it's been noisy and vibrating as long as I've had it.
The plan was to remove the bearings so I could identify them and order proper replacements, but my puller wasn't big enough and I just couldn't get them off.

That's okay though because they actually turned out to be perfectly fine, and since I needed my grinder for something I decided to just put it back together then figure out what the actual problem was sometime down the line.

Well I got it back together and damned if I hadn't inadvertently fixed whatever the problem was.
It runs smooth & quiet now and no longer vibrates all over the place.
It's rusty and basically missing everything so it may not look pretty, but it runs flawlessly now.

Is it possible the issue was power related due to the switch and the undersized cord ?
Or did I make some change to the balance when trying to get the bearings off ?

I have no clue, but am just glad it's running well now.

A poor connection, either on the switch or the cord, would draw more amps but not affect the run quality. More likely when you reinstalled the bearings you either cleaned and lubed them first if they were ball bearing type, or just installing them squarely and cleaning in general affected the run quality.

In any case, good job!

I couldn't actually get the bearings off, and I didn't do anything other than try to remove them.
There has to be something that was misaligned , or maybe the wire wheel or polishing wheel were off center a bit.

In that case, I would bet that one of the wheels was misaligned.

In that case, I would bet that one of the wheels was misaligned.

That is most likely,  but I remember it having always been this way and I have had the wheels off before.
I suppose I may have previously put them back on poorly.
