My grandfather passed away when I was 16, while getting his things in order, I found this old grinder in a barn, mice had chewed all the wires under the base. I brought it home and re-wired it and it runs as smooth as butter. I just cleaned it up and left it the way it was....I've been using it for 50 years now and it still runs like butter with hardly any noise when it's running. I put a couple different scotchbrite wheels on it and I use it in my shop for polishing metal. I looked it up a while back and found that it was made in 1934....try buying one now that will last that long...lol I just thought it would be something different to post here....I think about my grandfather every time I use it.....
