$100 for a cast iron 8" grinder is a lowball price.It’s a widow selling it so don’t really want to lowball her.
Provincial, what is the model number for your machine? I may be able to source a wheel cover for that model number that would fit on my Van Dorn.I have a Black & Decker 10" version of that grinder. B&D bought out Van Dorn and kept making them just the same. It has great bearings and runs smooth. It is very powerful, so I think the power ratings are quite conservative. I'd jump on that one if you have any use for it!
