The wheels on my grinder get used for a number of tasks around the shop. And after a while, the grinding edges end up with uneven wear. Small grooves or a face that isn’t square with the tool rest can really affect the performance of the wheels, especially when sharpening tools. To keep my wheels in top shape I made the jig you see here. It utilizes a single-point diamond dressing tip to true up a wheel’s edge.
It’s just a short block of hardwood with a hole drilled to accept the dressing tip. A threaded insert and thumbscrew at the opposite end of the hole advances the tip towards the wheel. Another insert and thumbscrew on the top of the block locks the tip in place. A section of aluminum angle on the bottom edge of the block registers the jig against the tool rest. Use the jig to keep your wheels true by slowly sliding the block from side to side across the tool rest.
