I set out with the intention of making a sturdy, reliable, and mostly simple workbench. As I was tired of not having a proper location to work on projects, or brainstorm creative solutions for existing problems.
A few years ago, I had a basic idea in mind of a large, long work bench with a replaceable work surface, a lower shelf and pegboard for tool storage/organization. Another design goal was to ensure I had the ability to break it down with relative ease when I eventually move.
I had a pre-existing plan in mind, but adapted the method of sandwiching the posts, and temporarily supporting each shelf from: http://www.instructables.com/id/Heavy-Duty-Work-Desk/Materials:
Two (2) 4’x8’ sheets of 5/8” plywood
Three (3) 4x6x10’ treated wood posts
One (1) 4‘x8’ sheet of 1/4” pegboard
One (1) 4‘x8’ sheet of 1/4” hardboard
Twelve (12) 2x4x8’ boards
Twenty Four (24) 5/16”x6” carriage bolts
Twenty Four (24) washers
Twenty Four (24) hex nuts
A large number of 3” deck screws
