<p>I&rsquo;ve attached a picture with notes but this is what&rsquo;s needed:</p>

<p>-Lower centre stone so its in line with the outer stones<br />
-Make claws slightly heavier<br />
-Make shank profile flat on the inside &amp; out<br />
-Alter shank depth to be 2.0mm deep from 3 o&rsquo;clock to 9 o&rsquo;clock &amp; graduate to be 3.0mm deep at the point where it meets the head.<br />
-Angle the shank in to meet the bottom of the head &ndash; not wider than the head( see image attached )</p>
