Here's how it's used. This isn't for power reaming it's just a way to keep things aligned. In use the head stock is held stationary and the reamer turned with the knob.
It was difficult for me to adjust the reamer so I made two little "wrenches" and I use them as shown in this picture:
Makes adjustments a snap.
