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
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,
