Appendix 2
Measuring the Brake Torque
170
If you do not have access to a torque-measuring instrument, you
could easily make a provisional instrument using a roll of spent
transfer ribbon, a simple dynamometer and a ruler:
• Fit the ribbon roll on the spool you want to check. The larger
roll, the better accuracy.
• Measure the radius from the center of the spool to the edge of
the ribbon roll.
• Fit the end of the ribbon to the dynamometer and pull.
• Read the dynamometer.
• Calculate the torque using the formula:
Torque (Nmm) = Radius (mm) × Force (N)
