− | * | + | * They replaced the (2) Tetrix drive motors with (2) am-2964a motors, thereby gaining integral encoders with the new motors. |
* It is clear that the worm gear - output shaft connection on the forward drive extension elevation is prone to slippage. This connection is achieved via (2) small set screws on a 3/16" steel shaft. Frankly, this connection is not likely to be adequate or reliable. | * It is clear that the worm gear - output shaft connection on the forward drive extension elevation is prone to slippage.

* Plan for the worm gear output is to purchase the tooling to enable us to replace the 3/16" output shaft with a 6mm shaft ant to use a 2mm key to fix the worm gear and shaft in rotation. Tools required are a 2mm end mill and a 2mm broach with 6mm bushing. | * Plan for the worm gear output is to purchase the tooling to enable us to replace the 3/16" output shaft with a 6mm shaft ant to use a 2mm key to fix the worm gear and shaft in rotation.
