On the jig itself there are two adjsutment knobs. One at the rear and one at the front. Place your vane or feather in the clamp at which ever mark you choose to use. DO NOT PUT ANY GLUE ON THE VANE. Place an arrow in the jig. Now loosen up both screws that hold the adjustment knobs tight. Adjust the rear of the jig until you get the rear of the vane to make good contact with the shaft on both sides of the vane and lightly tighten the screw. Next do the same to the front knob.

You should be pretty close to having 100% contact between the vane and shaft. If not you can make fine adjustments until you do.

When you glue the vane I like to use AAE fast set gel. It works great on vanes and feathers. Make a small bead right down the center of the base of the vane. Apply clamp to the magnet and slide it down until the it makes contact with the shaft. I like to have the rear of the vane make contact first and then gently "roll" the rest of the clamp into position until the entire vane is making contact with the shaft. Give it a little push against the shaft (not too hard) and let it sit for about 15 seconds. Open the clamp and remove and rotate the nock for the next vane.
