2ND AXIS AND 3RD AXIS OF A SIGHT

Check the 2nd axis of a sight before you try walkback tuning.

1)

Insert a 6-inch long 5/16-24 bolt into the front stabilizer hole of your bow. Clamp the bolt into a vise and rotate the bow until the bow is vertical. Use a carpenter's level to confirm the bow is perfectly vertical.

2)

Check the sight bubble. Adjust the bubble on the sight until the bubble reads level when the bow is confirmed to be perfectly vertical.

You just adjusted the 2nd axis of the sight.

3)

3rd axis of the sight is what I call adjusting the "door swing". Imagine that your sight ring is connected to the sight extension bar with a set of very rusty hinges. Lets say, you bumped the sight ring and the sight ring "door" swung 45 degrees towards you. The bubble still reads level.

If you shooting at an uphill or downhill target, the bubble will lie to you and you will have to tilt the bow to get a "level reading" on the uphill or downhill shot. Then, you will wonder why you missed left or right.

Easy fix.

Hang a weighted string from the ceiling.
Load an arrow and kneel on your knees.
Come to full draw and anchor.
Line up your left edge of the bow limbs with the weighted string.
Look at your bubble level.

If you line up the left edge of the bow limbs, and the bubble is not reading level, then you must follow your sight instruction manual and adjust the 3rd axis screws.

Get on your knees, load an arrow, come to full draw, line up the left edge of the bow limbs, and check the bubble level again. Repeat this process until the bubble level reads level.

Now, you have adjusted 3rd axis.
