I purchased wood and hardware to build the EAA Workbench. Cut the 2x4s to final size for most of the pieces. The 2x4 cross pieces were cut to final size after the frame for the top and bottom were assembled. The leg levelers are t-nuts and bolts with a locking nuts. I used drywall screws to put it all together.
