We need to make reference marks on the wheel to guarantee maximal wag.
- Carefully rotate the wheel to the far right and make a mark perpendicular to the servo body.
- Carefully rotate the wheel to the far left and make a mark perpendicular to the servo body.
- 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.
