Set-Up<br />
1. Find Center of Gravity<br />
for rotation.<br />
Workpiece should be placed on<br />
positioner with the center of gravity<br />
coinciding with the rotational axis of<br />
the table. Movement of the object<br />
around table rotational axis is<br />
almost effortless. In order to prevent<br />
over-travel of mounted objects,<br />
<strong>Koike</strong> Aronson has applied friction<br />
bands to the rotation point of the<br />
worktable which generates slight<br />
resistance and allows the load to be<br />
stopped at any desired point.<br />

2. Finally, balance workpiece by<br />
adjusting wormgear so tilt axis<br />
intersects center of gravity of<br />
rotational axis.<br />
0-30°<br />
By a simple adjustment to the<br />
wormgear, the tilt axis can be<br />
aligned to intersect the rotational<br />
axis. At this point, both axes<br />
intersect the object’s center of<br />
gravity and move freely in any<br />
direction.<br />
