I'm kicking around ideas for a CNC conversion to my 6 x 26 knee mill. I want to retain the hand wheels for manual use and ideally want to disconnect the stepper motors to remove the magnetic steps when in manual mode. I need a neat method to connect/disconnect a timing pulley from the shaft it is running on. needs to be 100% positve action and minimal backlash. Any ideas chaps? links etc
TIA
Bob
