I use my grinder almost exclusively for beveling my chisels, so I like to keep the tool rest set to produce the 25-degree bevel I prefer. Having to reset the angle after using my diamond wheel dresser to clean and flatten the wheel bothered me until I made this wedge-shaped support. Like many of my friends, I've upgraded my grinder by installing a top-quality tool rest (see Source, below). The wedge-shaped support I made fits snugly in the tool rest and instantly positions my diamond dresser correctly, perpendicular to the wheel's face.
After drawing the support's profile on the end of a 12-in.-long, 1-1/4-in. x 1-3/4-in. blank, I headed to my tablesaw. First, I cut a rabbet on the back of the blank to create the tongue. Rather than going for a precise fit, I cut the tongue a bit narrow and planned to install adjustment screws later.
Next, I cut the bevel. Its angle depends on your preferred bevel angle, the size of your grinding wheel and the location of your tool rest relative to the wheel. After checking to make sure the bevel's angle was correct, I cut the support from the blank and installed the adjustment screws. Now, switching from grinding to dressing is effortless.
