Cylindrical Grinding on a Surface Grinder
How do I do cylindrical grinding? For a long time, the grinding capability that I have was limited to a 6" x 18" Boyar-Shultz surface grinder. I saw my lack of cylindrical grinding capability to be a problem that I would at some point or another, need to confront, considering that I make a lot of gears, and gears often need to go on shafts that are of a precise diameter.
My 'get-by' solution was to acquire one of these nifty things:

With this setup I can easily achieve diameters within one ten-thousandth of an inch (0.0001").
Here's a video of using the fixture, to grind a custom motor rotor shaft, for a high speed brushless dc motor:
