From working countless hours in sheet metal fabrication shops, I think the biggest danger is getting out of syncopation between your hands (which are handling the work) and your foot (which is mashing down the pedal). It's nice to see old school methods are still being employed in todays computerized digital CNC world.
That box plant reminds me of a project I worked on at Fort Worden, an old turn of the (20th) century army base. We were remodeling the old base machine shop, in which all of the equipment was belt-driven. The equipment was all removed, but the overhead system ofdrive belts & pulleys (which may have originally been steam powered?) was left in place as an exhibit.
