Step 13. Inserting the spacer washers
There are some spacer washers that must be inserted so that the tilt assembly can rotate smoothly. The
easiest way I know to insert these spacer washers is to lie the pan / tilt assembly on it's side with the tilt
bracket at about 40 degrees when the tilt servo is centered as shown in the first photo.
Stack your spacer washers neatly and insert them as best you can with your hand or long nose pliers as
shown in the second photo.
Use a plastic cable tie to gently push the washers into position as shown in the third photo. Once the
holes line up it's easy to insert your 2.3 x 10mm screw through the brackets and washers into the servo
output shaft.
Tighten all the way being careful not to overtighten and then back off 1/4 of a turn. The tilt bracket
should be able to tilt up and down fairly easily. Loosen the screw a little more if required.
Do the same on the other side with the 3 x 10mm machine screw and nylon nut on the other side.
NOTE: The nylon nut should be slightly loose so that the tilt assembly can move easily.
