The material shown is mostly pine or spruce except for the fold
down table surfaces, drawer bottoms and part of the leg and table support holder on top of the box which are
3/16" plywood.
Dado joints and rabbit joints are used to improve surface contact and
strength for glue joints. Most of the material is planed to 1/2" thick, to reduce weight. The front and back table/work
surface is attached to the box with a full length hinge.
Truck latches are used to fasten the fold down table work/surfaces
and top storage rack for the table supports and legs. Bolts with wing nuts are used to attach the table supports to the legs
and also to attach the shelves on each end.
Steel "D" ring handles were added to each end to provide a way to carry
the finished box. When the box is bolted together as shown the entire assembly can be picked up and moved.
