Elevation Servo
The elevation servo pulls back the mirror with the elevation cord.
1 Cut a block of 10cm by 6cm with thickness of 3cm. |
 |
2 Draw the dimensions of the servo in the middle of the block |
 |
3 Cut out the servo hole (similar as in the mount) |
 |
4 Try fitting in the servo ... |
 |
|
5 ... and set the block on the back end of the azimuth arm. It should counterbalance the mirror front. Glue the block to the azimuth arm. |
 |
6 Set the two-arm rudder on the servo and connect the elevation cord to it. Thread a single strand wire through a hole of the servo rudder and knot it with a bowline to the elevation cord. |
 |
7 When you place the servo rudder on the servo take care that the leftmost position pulls the mirror back as far as it goes (about 30 to 40° to horizontal line) and the rightmost position releases the mirror to vertical position. Note that you can pull the mirror further back when you set the mirror elevation mount closer to the middle. |
