=== User: Default setting on arm length is 24 inches. ===
Default setting on arm length is 24 inches. That applies to both arms. Both arms have the same length, no matter what. Now, at the top of the top unit and at the bottom of the bottom unit, where the arms come out of these units is a pulley system. The whole intent of this pulley system is as follows. It takes from the vertical, coming from the top, down at the arm or from the bottom, and up the arm battery on the unit. The bottom unit comes up and goes up the arm to the pinion, or wherever the pinion is at that moment. Okay? Same with the top unit. The top unit goes through the pulley to the pinion on the top unit's rack. There is a further line beyond these two pulley lines, and that is from the pinion to the pinion. And the distance between these is set at 4 inches. It will always be 4 inches, okay? Now, line comes in through the top to the pulley to the pinion intake portion of the drum there. There is an output drum on that same pinion that goes down to the bottom pinion intake. The output from that pinion goes through the bottom pulley and down to a weight. There is also a weight attached to the line after the top unit's pulley. They are primary weight and secondary weight. Primary weight is the one at the bottom. The secondary weight is the one that is connected through the top. The top has got extra pulleys as necessary to bring it away from this unit. You don't need to worry about that. User input can change the weights, but secondary weight can never equal or exceed the primary weight. We use pounds. All measurements are going to be in imperial, not in metric.
