The driven pully bore and shaft size are correct. The set screw pushed the pully up, will be fixed. The nut holding on the wire wheel isn't left hand thread, also its a very thick, so it looks like its not on that far. I understand if it spinning the wrong way it would back off the nut, that...

I plan on tightening it, the video I took was right after it was done as a test.

I think it turned out alright. The sheet of plastic is a guard. I know it's ugly, it's temporary. My old bench grinder was a piece of **** Black & Decker from the 90s. I think an upgrade to a belt drive. I sacrificed one of my motors from my collection, not really a sacrifice, as it's not that...

http://vintagemachinery.org/ is a lifesaver when it comes to this kind of stuff. I find myself getting lost in the millions of files on there. You're welcome!

VintageMachinery website has a manual for the same model, but a different design. Manual I found says about 1961. I imagine yours isn't far off. http://vintagemachinery.org/pubs/detail.aspx?id=5655 Im on my phone right now, I couldn’t view the file, so good luck.

True, I'm going by Tractor Supply tomorrow to get some collars. Also, the model bearing I was looking at was about $20 a piece! I ended up ordering some alternative bearings with the same dimensions, should be here later this week.

Old one, not sure how old. Might restore it one day.

Brake cleaner did the trick. It worked way better than I thought it would, and the inside looks brand new.

I have an old belt-driven grinder, made almost from scratch by my great-grandpa. Of course, the bearings are shot. The bearings have a lip on either side and are held in by these 2 metal brackets. One was held in by JBweld. My question is, can I take the shaft collar (bottom left of picture) and...

Didn't even cross my mind, good idea!

As the title says. Pretty sure it had chainsaw oil, but it sat in the bottom for a long time. I have it filled with water, Fast Orange, and some mystery soap. When emptied there is still a black sludge im the bottom, any ideas? I plan to use it for my electric motor oil.

Niche topic but still interesting. Found this in one of the shelves in the garage from the 50s. I imagine it was my great-grandpa's, a lot of the stuff there was his. I have never seen this brand before, the only thing I could find is a Meteor electrical wholesale place. Any info on its age or...

talked to my uncle, and he said that on condenser fans, they have to have some wind direction device, because the pitch of the blades is weird, so it would push the air to the sides without the shroud. Is this true?

The label on mine doesn't say it can run on 120, would it even say if it could or not?

Yes its 240v, my uncle works in HVAC and may be able to provide one that runs on 120.

I'm pretty sure the one pictured in my first post has an option for PWM (Pulse Width Modulation) control, for I assume controlling the speed. Not sure why it needs it for a condenser fan, but its there.

Has anybody done this before? I have one with an ECM motor, and I might find a different one to use. I haven't seen anyone do this before. Is this a good idea? I would obviously build a cage and guard.

I removed the brush adjustment bracket and readjusted it, it had fallen a bit and was pushing the brush assembly forward. I oiled the brush lifter, and it seems to be doing much better

I just received this motor in the mail today, but it appears that the brush lifting mechanism is acting strangely, sometimes leaving the bottom two brushes connected. I have a video of it I will add. I took it apart and reassembled it, and it made no difference. It also makes a quite obnoxious...

I posted a thread about this the other day, but I since got the motor running. I may have forgot to mention the inside of the motor was coated in oil, now I found out why. I added my own 3 in 1 motor oil and I noticed a little bit of the old oil started running out of the overflow, then a puddle...
