You could try to fit a pulley to where the hand wheels are now. Then wrap with a string and hang a weight to the string. Keep adding weight until the axis moves the way you want. The torque will be the weight times the radius of the pulley. A spring scale would probably more convenient to use, if you happen to have one. You will also need to add some torque to account for cutting forces. If you have leadscrews instead of ball screws, the cutting torque will need to be much higher. I strongly suggest having preloaded ball screws to reduce the torque needed, but more importantly, get rid of backlash. -- Kirk Wallace http://www.wallacecompany.com/machine_shop/ http://www.wallacecompany.com/E45/ ------------------------------------------------------------------------------ Subversion Kills Productivity.
