On its own four feet
This past weekend I mounted the legs into the massive mortises that I had cut into the workbench top. My wife and eight year old son then helped me to "flip" the giant, heavy beast onto its feet.
Next step is to plane and install the under-shelf material, make the sliding deadman and vise chops and install the twin-screw front vise. After that, drill the dog holes and other work holding, flatten the top and its complete.
I think that I am about a week and a half away from completion.
