How to Make a Home Cigar Humidor

What You'll Need
A hygrometer
A humidifier
Hardwood for the exterior
Spanish cedar for the interior
Polyurethane finish
Wood glue

A cigar humidor is a box designed to store and age cigars within a certain humidity range, usually 68 to 72 percent. Its main purpose is to store, preserve and age cigars for a number of years. It contains a humidification system, which is a device to add or remove moisture from the inside to maintain the desired level of humidity. In most cases, a humidor contains a hygrometer to measure the humidity levels inside the box. Most personal humidors are made out of wood.

Step 1 -- Making the Building Plan

When deciding on the overall dimensions of your humidor, you should take into consideration the size and the number of cigars you will be storing. This plan is for a box of 18 inches by 9 inches by 6 inches, with an inside divider that is 10 inches from the right side. This box allows the storage of cigars 6 inches or shorter on the left side. The longer ones can fit horizontally on the right side.

Step 2 -- Building the Humidor 

Cut the wooden boards in order to fit the sizes calculated for the sides of your humidor. The top lid is 9 inches by 18 inches. The bottom is 7 1/2 inches by 16 1/2 inches. The bottom is smaller than the top lid so that the sides cover the bottom's side edges. You can shape the edges with a router bit to give them a nice finished appearance. The front and back are 5 1/4 inches by 18 inches. The sides are 5 1/4 inches by 9 inches. Miter the ends of the front, back and sides 45 degrees to form the corners of the box. Next, cut four 3/4-inch-by-3/4-inch pieces of blocking to make a stop on the underside of the box lid to make an airtight seal when it is closed. Assemble the box with wood glue and 1-inch 18-gauge nails. Use clamps to hold the pieces tightly together and let the glue dry for at least one hour. Then, proceed to the nailing. 

Step 3 -- Sanding and Finishing

Sand the exterior and the interior to ensure an even coating with polyurethane. Apply two coats for the interior and five to the exterior. Use steel wool to sand in between the exterior coats for a smooth and polished look and feel on your cigar humidor.

Step 4 -- Lining with Spanish Cedar

Use a 3/8-inch Spanish cedar liner for your cigar humidor. Cut into pieces and glue them in, making sure to cover all the inner areas. The Spanish cedar must be unfinished in order to work properly in absorbing excess moisture.

Step 5 -- Adding the Hardware

Place the hygrometer inside the cigar humidor with its sensors on the side of the device. Install the humidifier, using glue to place it inside the top. After doing that, fix the brass knobs to the front part of the lid to enable a comfortable opening action. Finally, attach hinges to the back of the humidor.
