I wanted it to 1) fit my small work bench / project table, 2) be inexpensive, 3) be easy to construct, 4) really work!
Step 1: Wooden Base Assembly
I cut the pieces to form a "T".
I cut the long piece to fit across my work table, so I could clamp the finished "T" top and bottom.
A board was placed across the top of the "T" pilot holes drilled, then screwed together.
