I have been working for two days on a sheet of plywood between two HD metal sawhorses. The sawhorses have a place for two 2x4 s that support the plywood. I have been having to rest after 30 minuets due to back issues. My standard bench is a Compact Hoffman & Hammer, now at my new home. I believe it is around 32” tall and maybe 20” wide. I have not had these issues with my regular bench. I am wondering why? I am about 5’10” tall.
I read Derek Cohens Blog regularly, incuding the history of his last bench build. As I recall Derek built his bench lower based on suggestions that a lower bench might allow the user to use legs better. I believe he later raised his bench height, maybe because of similar issues? The plywood I have been working on is about 29” off the ground, which is about the height Schwarz suggests, based on the pinky last knuckle measurement.
The other thing is I am reaching further than I normally would, across a 4’ wide table, clamping shutters I am glueing up. This may be the reason or one of the reasons.
I am working on bench builds and I am particularly concerned with how wide and tall to make them. One bench is a Noden adjustable height bench/work table, still I am wondering about the minimum height.
