How to Build a Tool Chest | A Woodworker’s Step-by-Step

For the full breakdown, see our best Tool Chest Workbench Combo guide.

Building a tool chest is one of the most satisfying shop projects you can take on — a custom home for your saws, planes, and chisels that fits your exact collection. The process comes down to one rule: measure your tools first, then design the chest around them. This guide walks through the full build, from sizing to hardware, with published dimensions you can adapt.

What Size Should Your Tool Chest Be?

Start with the longest tool you own. One popular plan is sized specifically to accommodate a rip saw, and historical guidance agrees the chest length should clear your longest saw. Measure everything you intend to store, then draw the case dimensions to fit before cutting any stock.

Published plans give you a solid starting range. A modern plan for a hand-tool chest uses exterior dimensions of 28 in. wide × 14 7/8 in. deep × 15 in. high. Another plan set suggests a range of 24–28 in. long, 12–14 in. wide, and 12–14 in. high. A traditional reference from the early 20th century calls for internal dimensions of 2 ft. 9 in. long, 1 ft. 8 in. wide, and 1 ft. 9 in. deep — roughly 33 × 20 × 21 in. — with case walls at least 1 in. thick and a lid overhang near 1 1/2 in. on all sides.

If your tools run longer than a rip saw, extend the case accordingly — the dimension that matters is the one that clears your longest tool, not a round number.

Key Construction Choices: Materials and Joinery

Mill your stock flat, straight, and square before any joinery — this one step determines whether the case assembles cleanly. Most modern plans thickness case parts to 3/4 in., leaving the lower case and lid panels slightly oversized at first, then trimming them to final cut-list dimensions after assembly. Traditional builds use heavier 1 in. stock for the case and tongue-and-groove panels for the lid, joined with dovetails for strength.

For the joinery, closely spaced dovetails or box joints are the classic choice for a tool chest carcass; a traditional source recommends tails no more than 1 1/2 in. apart to resist racking. Drawer parts commonly use rabbets and dados. Use white glue or a slow-setting adhesive — Titebond Extend gives you extra open time for a carcass this size, which helps when clamping six panels square at once.

One caution: when setting up dovetails, leave extra length on test pieces, and score the baseline first to avoid tearout on the finished parts.

Building the Chest Step by Step

With your stock prepped, the build proceeds in a clear sequence: cut parts to size, dry-fit the panels, then glue up the case. Dry-fitting first is non-negotiable — it shows you where joints bind before the glue is on. When the carcass goes together, clamp it square and check both diagonals before the glue sets.

Next come the drawers and internal trays. Modern plans cut drawer bottoms from 1/4 in. plywood, then build the sides, fronts, and backs around them. To make drawers slide freely, leave the grooves about 1/64 in. wider than the hangers they ride on — a small clearance that prevents binding as the wood moves with humidity. Build any interior trays to the same standard, sized against the tools they’ll hold before you commit to dimensions.

The lid comes after the case is solid. Use the same kind and thickness of material as the chest itself, joined with tongue-and-groove panels for stability. Traditional plans call for hanging the lid with strong brass butts — they won’t fatigue or loosen the way lighter hinges can under a lid loaded with tools. Install the hinges, a lid stop, and handles, then finish the piece.

A tool chest workbench combo is an excellent upgrade if you want your tools and work surface in one unit — worth reviewing before you commit to a standalone build.

Fitting Hardware and Finishing

Install the hinges so the lid closes square against the overhang — about 1 1/2 in. on each side if you followed the traditional proportions. Add a lid stop to keep the lid from opening past vertical, and choose handles that sit comfortably when the chest is fully loaded. Apply finish after the hardware is fitted; several coats of oil or varnish protect the case and make drawers glide more smoothly.

Most published plans are written for US woodworkers with inch-based measurements, and they range from small portable chests to rolling cabinets. The dimensions above adapt to either — the principle is always the same. Measure the tools, size the case, and build the carcass before you worry about the details.
