E1 Precision Limb Alignment Tool

Designed and manufactured in Australia by a master engineer.

Steps;

- 1 Mount bow on a flat bench the same length as the strung bow, with room for clamping the angled brackets.

- 2 Move the limb adjustment screw until the top surface of the Aluminium measuring tool is pointing at the center of the string 

- 3 Move the limb adjustment screw until the top surface of the Aluminium measuring tool is pointing at the centre of the string.
Tighten up the screws so that the limb is locked in the correct alignment. Repeat the process at the other end. Check the first limb again to as it may need realignment due to the movement of the second limb

- 4 Using the digital caliper, make sure the calipers are closed. Turn them on and press the zero button.
A measurement is required from the upper surface of the sight window to the bench next to the arrow rest, but not including the arrow rest.
This is done by moving the two parts of the digital caliper apart and using the thin rod that appears to touch the bench then moving the main part of the caliper so that it sits on the surface of the sight window. Write the number down on paper as it’s the first measurement required to set up the pressure button.

Measuring the arrow diameter 

this needs to be done at the point 

on the arrow just before the click is

activated. 

Measuring the sight window thickness at the point where the pressure button passes through the 

riser. don’t include any internal arrow

rest in this measurement.

sight window thickness measurement 

External mounted arrow rest needs to be included in the measurement 

to calculate the correct pressure button

The full calculation comes with the limb alignment tool.
