Workbench

A single workbench height would never suit me. Standing workbench is 42 inches high and substantial enough to support drill press, 10" diameter bench grinder, vise, most anything. I do have 8 inch high plywood box to place and step up onto when needed. The sitting workstations are standard 30 inches high.
A back wall that separates basement from crawl space that looks like wood paneling is actually painted steel wall from above ground swimming pool. It's not where I throw sparks but I could.
