If you have things with sharp edges that get dull with use, a grinder is one of the ways to fix that edge. In my case the edges were on lathe chisels. Sharpening has always been a challenge for me and I look for anything that will make the job easy and the result useful. For this repetitive task, I chose a Wolverine Sharpening Jig system and the Woodcraft 8" Slow Speed Grinder to use with it.

This grinder cost more than the 3750 RPM versions at your local hardware store, but the cost, for me, was justified. A slow speed (1725 RPM) grinder is less likely to blue the edge of a tool when you sharpen with it dry. Also this grinder came equipped with white aluminum oxide grinding wheels in 60 and 120 grit. These grinding wheels are much better for producing a sharp edge than the gray wheels that come on most hardware store grinders. The 8 size reduces the concave bevel that grinding on the edge of any wheel gives. This is also a good thing.
I have this grinder set up as part of a sharpening system for my lathe chisels. It works well. It came with rubber feet attached, but I have removed these. It also came with a couple of flimsy platforms, a couple of spark shields, and a couple of spark arrestors. None of those pieces got installed. Construction is adequate as is the fit and finish. There is some low rumbling as the wheels spin up when you flip the switch on the front of the pedestal base. It doesnt seem to hurt the grinding action. I miss the attached gooseneck lamp that comes with some grinders.
There are many other wheels for honing or polishing that can be placed on the 5/8 shafts of this grinder. I am considering replacing the 60 grit wheel with a honing leather wheel, but havent gotten back to Woodcraft to get one yet. The 2/3 HP motor is pretty quiet except for the low rumble and slight vibration. Even the little vibration was improved when I trued the wheels with the diamond wheel dresser that the folks at Wolfcraft talked me into. I would likely be much less satisfied if I had to depend on the supplied platforms to do my grinding. With the Wolverine Grinding Jig in place I am pretty happy with this addition to my small workshop.
