Purpose and Design Choices
This construction seeks to create a practical, metal home-office / gaming desk. In designing everything, I found it very difficult to find well-written instructions for DIY desks that weren't gimmicks, such as "Cinder-Blocks and a Door", or "Hang a Desk From Your Ceiling." This guide is meant to be educational, easy to understand, and highly-detailed.
Large desks are heavy and difficult to transport, this desk is designed to be light-weight, sturdy, and easy to assemble. Kee-Klamp joints are the basis of the construction, and require only a Hex-Wrench to attach or remove. Aluminum is the plate material, for the reasons of A) Rigidity, less flexible than steel; B) Weight, lighter than steel or hardwood; C) Soft metal, easier to polish, cut, and drill; D) Resistance to corrosion or discoloration.
This is a costly project, the total for the two desks, with parts, shipping, and tax, was around $420. This price is assuming that all plates are obtained used, not new. There is also a large investment in time, I designed and assembled everything during the weekends over two months. This does not include the cost of power-tools, which are listed on Step 1. The cost can be lowered by not using flanges for feet, and buying only one large plate. Despite being over $400 for two desks, it is easy to spend more than that on a low-quality, particle-board pedestal desk; the burden of cost for this project is time, not money.
Every day I use this desk, and I am extremely satisfied with the results. I hope you enjoy and learn from this instructable, and encourage you to adapt and modify this knowledge to suit your needs. Good luck, and enjoy!
