Hellow fellow engineers!
I need your help. Yes! Your help.
I need to create a gear mechanism that can be operated by two knobs. One knob when rotated it engages a gear or the other (there are two - similar to a differential) or engage both gears at once or put them in 'nuetral'. The other knob rotates the gears when 'engaged' by the other knob.
Need this asap
