Here a picture of the complete assembly in the retracted position. Operation is smooth and easy.
Here belt tension is released, travel is a full 2", thats 4" of belt length, should be plenty.
In the next two pictures I have repeated the two same operations but with the 80 lb. motor on it's base. Operation was just as smooth and easy as without the motor.
Here in the tension released position.
So this is a long weekend here, so stopped early to crack open a bottle of the captain's finest, we also have heat warnings for the weekend, so it will be going down good with mountains of ice. Hopefully get started on the bearing assemblies and wheels Monday.
