Use this calculator to determine the SAFE TORQUE (in inch/ounces) for your rubber motor. Input your motor's rubber width (in decimal inches) and how many strands (1 loop = 2 strands). If your motor is made of loops of two different widths, input the supplementary loop(s) in the SECONDARY input areas. Note: this program is based on Don DeLoach's published table of torque values, using his T-75 (75% of max torque) as the baseline. Click HERE to read Don's original article |
