Scott Rumschlag is a builder. Who earned two engineering degrees from UM, a BSE & MEng in Civil Engineering, before discovering his aversion to office work, and switching to carpentry. One of those US « remodeling, repair and home improvement contractor » (his words), who can do (nearly) anything out of wood.
While running a 2-men job specialized in bath and kitchen remodeling, he designed and build (over several years of trial & error) an amazing rotating expandable table. Check the Backstory.
