We need to make reference marks on the wheel to guarantee maximal wag.

1. Carefully rotate the wheel to the far right and make a mark perpendicular to the servo body.
2. Carefully rotate the wheel to the far left and make a mark perpendicular to the servo body.
3. Then, divide the distance between the two marks in half... make your final mark.

This, will be your guide when lacing the wheel.

At the mid-point, drill a hole into the wheel.

Flatten the area to that the screw sits flush against the wheel.

Either tap the hole or pre-thread with a warm screw.

Lace the beading-wire through each pully, around the servo wheel, and secure at the mid-point of the servo wheel.

Rotate the wheel carefully to make sure that the wag looks right... asjust as necessary.

When you're satisfied, add a little hot-glue to make sure that the beading-wire won't budge.

Trim excess beading-wire...

Grab a spring off an old and dead ballpoint pen... we're going to use it for automatic slack adjustment.

This will help prevent the beading-wire from falling off a pully.
