1 HP, 240 Volt, 1740 RPM.

I got this grinder when I bought the 1910 carpenter shop at the Pioneer Sugar Mill on the west side of Maui in 1998. You can read that story of cast iron fever here;
I know it sounds crazy but when I previewed that whole mess I fell in love with this grinder and that is largely what motivated me to do the deal; I really wanted this grinder. It is the only machine that kept from that whole thing. You might say that this little grinder is why I was so willing to do the tremendous amount of work that was to clean that shop out. No regrets.
Anyway this has always been a companion to my Oliver lathe. I keep it next to the lathe and it is set up for grinding turning tools. It is a very well loved machine of mine and runs extremely smooth, just like you like em. On the right is an 8" x 3/4" x 120 grit wheel with a Wolverine jig for grinding gouges, painted hi vis pink so I don't impale my hip on it when it's extended for use. On the left is a 10" x 1" x 120 grit wheel for grinding other lathe tools, skews etc. I put a plywood shelf in between the pedestal and the grinder to be able to attach those accessories. It raised the grinder a little bit making a better working height too.
I made a big mistake in my fervor; I painted this (Oliver green) before I realized that it had only 3 leads coming from the motor. The badge is stamped 440 volts (only) and the grinder looked very original, and at the time I did not have 480 in my shop. Also every thing else in the mill shop was setup for 480 volts. So I took it to the motor shop to see if they could relead it or something to 240 volts. The dude told me that it "rang out" at 208 volts and he did not instill a lot of confidence in me, but they did chip the heck out of the paint while it was in their charge. I often wondered if he really tested it or if they just wired it up to 240 and, since it ran, its good? But I put the grinder into service, at 208 volts, in my old shop, with intentions to check that voltage thing out further someday but did not get around to it. So fast forward to now I am just now getting around to setting this grinder up again for business in my new shop and I thought of the flaky guy in the motor shop. I also have an Ekstrom Carlson #18 double pump sander that is missing its badge; only 3 leads coming from motor, voltage unknown. So today I wired it up to 240 and it ran but did not sound really right. So I switched it to 480 and it ran great, smooth and cool. Mystery solved the primitive way, hey, I am not an electrician, I am a woodworker. So with that little breakthrough under my belt I decided to try that with the grinder as well, just to dispel that little nagging doubt in the back of my mind. So I did switch the grinder to 480 and it started great but got a little more than a little hot. So before the paint started peeling I switched her back to 240 for good. Now I know for sure and look at all the fun I didn't miss because of amp meters and hi tech stuff like dat. Thats how a woodworker does it!
Very cool grinder!
