The previous post about this work-in-progress can be found here.
I finished the rough metal work for the frame of the lift mechanism. The frame is designed like a truck frame. Here are some pictures.
Three Frame Parts
Ball Stops (not shaped correctly yet)
Overall View of Frame
The motor needs its own mounting plate to move the shaft back from the center of the frame. I still need to weld a base plate under the motor to keep the frame from falling over from the motors weight.
The frame is built from 1/8 inch steel plate.
