Workbench
A workbench is the first thing you should get since it will probably be central to most of your projects. A DIY workbench could be as simple as just slapping an old solid-core door or plank on top of two sawhorses. If you do want something more sophisticated, though, there are hundreds of easy-to-follow designs around the web.
Lighting
Inadequate lighting can affect the quality of your work and lead to time-and money-consuming mistakes. It isn’t too difficult, or expensive, to upgrade with ceiling-mounted fluorescent light fixtures that drop down from above your workbench to provide illumination where you need it most. Sometimes just adding one of these lamps to a dimly lit garage can lead to better visibility.
Flooring
The slab of cement as a garage floor is perfectly usable, but an upgraded finish will be more forgiving to dropped objects while making your floor more appealing and keep it that way by protecting it from spills. Some people like epoxy finishes, but modular tiles could be a better way to go.
Work Holding
Once your workbench is done, you’ll need a vise designed to hold your projects in place. When looking for your first bench vise, try not to buy the cheapest one you can find. Cheap vises are often poorly manufactured and are prone to premature failure.
Tool Chest
The more tools you own, the more important organization becomes; nothing is as frustrating as spending an hour looking for a tool you need for a 15-minute project. DIYers with a lot of tools should consider getting a roller-cabinet-and-chest combo.
Storage
Pegboard is the most economical way to store tools and pieces of equipment. There are different hooks available for hammers, extension cords, and other tools. Open shelves and enclosed cabinets offer greater flexibility for storing odds and ends. Some metal-frame shelving systems can be used either as single free-standing units or as double-wide units that can serve as a quick and easy workbench.
Extension Cords
If you find yourself looking for free power outlets, it’s time to consider power strips and extension cords. Use smaller power strips to make out-of-reach outlets more accessible. Longer extension cords are a garage necessity for uses like car repairs while a ceiling-mounted retractable reel offers greater range and eliminates the need to drag power cords across the floor.
