I am thinking about an 8" slow speed grinder. I have a 1" belt sander that I use for turning tools. I have a 6" high speed grinder I used for hogging metal, like lawn mower blades and axes. I use the Wolverine with both as the situation dictates, but am getting better with free hand sharpening. I also have the WorkSharp 3000 which does a wonderful job on chisels and plan irons. I have 8" wheels. I did once buy an 8" slow speed grinder but took it back as the shaft was bent and there were no more in stock.
So the question is, what does the 8" slow speed get me that I don't already have. The reason I am asking is that I am designing a cabinet to store sharpening stuff and I need to know if I need to design in a space for this.
