Cabinets come in different shapes and sizes, as per the needs of the customer. Many people tend to buy ready-made cabinets. However, with a little effort and planning, you can easily build a cabinet that serves your needs. If designed properly, the cabinet will provide enough space to store heavy instruments as well.
First of all, determine the dimensions of the cabinet. Decide the height, width, and depth according to what you plan on storing inside. The depth needs to be slightly bigger than the instruments kept inside. The width should be large enough to store the instruments that are generally found in a garage. Decide whether or not you want shelves.
Cut a piece of plywood in the same dimensions as that of the back piece to make a door. The door can either be a single or a double-pieced one. The door should be fixed to the structure with the help of the hardware purchased. Hinges and screws are needed to fix the door. Then, attach the doorknob. The hardware necessary to install the latch is put in.
Generally thin strips of wood are attached to the edges of the cabinet to make the handling easy and comfortable for the user. The legs should then be attached. To make the cabinet weatherproof, coat it with oil paint. Don't forget to paint the cabinet, since plywood is susceptible to moisture.
You can also add other features like drawers if you require. Ensure that you take necessary care while handling power tools.
