Two-Tier Cantilever Computer Desk

Project Overview

The desk was created to replace a bulky folding table in my grandparents’ home office. The goal was maximum usable workspace with zero corner posts (cantilever design), plus integrated storage and cable routing.

Materials & Tooling

• HSS 1½x1½x⅛ tube steel (salvaged)
• W6 wide flange scraps (for cantilever brackets)
• ¾” oak plywood + reclaimed trim
• MIG welder, grinder, drill press, router, clamps

Build Process

Step 1 — Layout & Sizing

Dimensions were set by the available room, with clearance for two monitors, a laptop, and a secondary shelf for papers.

Step 2 — Steel Frame Fabrication

Steel members were cleaned, fit, and welded. The cantilever arms were built from flange scraps, and all steel was sealed after grinding.

Step 3 — Warping Fix

Heat distortion warped the frame. We used a car jack and chain to compress the cantilevers into alignment.

Step 4 — Wood Surfaces

Oak plywood panels were cut, stained, and finished. Trim was added later to edge the desktops.

Step 5 — Cable Management

A small metal shelf beneath the desktop serves as a cable run and holds a power strip.

Lessons Learned

• Welding sequence matters to avoid frame warping.
• Car jacks are surprisingly useful for straightening steel frames.
• Scrap materials add constraints that lead to creative solutions.
