I designed and built this lovely standing desk a few months ago — these are the build photos.
My materials of choice were galvanized pipe, SpeedRail and Kee Klamp connectors, four heavy-duty locking casters, and a maple butcher block top.
I use it for my computer workstation in my workshop — it’s nice to be able to roll it around when needed. It would also make for a very nice workbench or kitchen prep table.
The top is 48″ x 30″ x 1-3/4″ thick. The legs are 34-1/2″ tall, so including casters and butcher block top, it stands at 38″ high.
