How do you setup a stereo microscope such that it doesn't give you a neckache, backache and with good wrist support. I have a stereo microscope in my lab which I use for soldering work. The bench height is not ideal but soldering work normally just takes seconds to complete. When I use it for watch repair work, after 10 minutes the neck and back hurts and the shakes start. Could you guys show me how you setup your microscopes? Thanks.
