Belt drive grinder build finished

[easton65]

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 rare. It's a 50s-60s GE motor, 1/3hp, 1725rpm. It is an open-frame motor, so I will likely have to do more maintenance to keep it running. Also, it's way more powerful than the one before.

The grinder part was homemade by my great-grandpa. I pulled it out of a barn along with its burnt Emerson motor. Replaced the bearings, and it works pretty well. PGN is the bearing brand I got. Though they claimed all of the dimensions were the same as the old one, it's not really accurate, so the thing runs really loud.

I will have a video of it running on my YouTube channel

Can you tighten the belt more?

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

And maybe use a cogged raw edge belt. They work better with small pulleys and the raw edge grips better with low tension.

Goos work though, you put time and effort into it and it turned out well.

Lotsa attaboys!

Geez, I like nostalgia and home made tools, etc, but this looks scary ...it looks like the driven pulley is for the wrong shaft diameter ( too large of a bore) ? also the nut holding the wire wheel isn't on by much ... is it a left hand thread? which way does the wheel spin?

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 wouldn’t be good. It looks scary, but its way better than it was when I first found it. Like I said before, the video I took wasn’t the 100% finished product.
