Here’s how to make a DIY workbench in about an hour. This workbench is made from all 2×4 dimensional lumber and less than one full sheet of 3/4″ plywood.
Here is the overall cut-list for the base:
8 x 28-1/8″ (Legs)
4 x 37″ (short braces)
4 x 67-3/4″ (long braces)
I cut my top at 42″ x 67-3/4″. It has 2 extra inches of width in order to overhang a bracket on the back of my table saw.
