I inherited this beautiful piece of machinery from a friend yesterday. It’s made by Mummert Dixon and It works, just needs a little cleaning up. Here’s my question- it appears to be an oil stone, is this true? And if so, what type of oil should I buy for it? And, do I put the oil directly on the wheel I’m going to use or do I put it in the reservoir at the top so that it’s distributed for me? Or do I just fill up the bottom and let the wheels pick it up? Any input you all could give would be much appreciated!

What makes you think it’s an oil stone and not a water stone?

I would not assume it is an oil stone grinder.

Lots of grinders used in metalworking have catch trays and
when grinding metals I always use water for cooling because it’s
so much easier to clean up. I don’t grind a lot of metal so
I usually just dip, spray or pour the water.

Also, is that a dust fitting on top?

It is an oilstone grinder. I Googled “Mummert Dixon” and came up with several good sites (OWWM and Vintage Machinery). There are some great photos and descriptions.

It is apparently an MD 450 Plurality Grinder (oilstone, leather strop, and high speed dry grinder). It looks like kerosene is the “oil” used in these, in the oil reservoir, recycled from the catch basin below the wheels. The wheels are wiped after oiling to keep your face dry.

Good luck on the restore, and you will never have an excuse to have a dull cutting tool again!
