In the design of this musical instrument, along with the traditional ones, there are also not quite ordinary details. For example, a pie mold is used as a resonator, and a ring-ring lanyard is used as a tailpiece.
Let's watch a video demonstrating how to play the banjo.
-Shape for a cake;
-Joinery glue ;
-Hook-screw – 2 pcs;
Step one: body
First you need to cut out the body parts. The technician measures the outer diameter of the mold in its upper part under the rim.
Added 2.5 cm to the diameter and cut out the first blank. Then I cut out the outer diameter.
The shape is made in the form of a cone. The wizard places the first ring on the mold, takes measurements and cuts the next disc. And so on until the very end.
The first blank is cut in the form of a disk. All others have a platform on one side to which the neck will be attached in the future. The size of the pad is 5 X 10 cm.
The very last disc must be solid without a cut in the middle. This disk will be the back of the case.
Step two: body assembly
The next step is to glue the body. For best results, it is better to assemble in parts, several rings, and then glue them together. When gluing, it is necessary to align the parts as best as possible.
After the glue is dry, sand the outside of the case.

Now you need to install a lanyard. It will act as a tailpiece.
The master cuts out two rectangular blocks of poplar with a length equal to the width of the body. Using a file and emery paper, it processes one of the sides of each block, giving them a rounded shape (for better fit to the body). Bonds the blocks to the body by spreading them to the sides and keeping them symmetrical about the neck. After the glue dries, it drills holes in the blocks and tightens the hook-screw into the holes.
Then he hooks the lanyard rings onto the hooks and twists the lanyard.
Step four: neck
The master makes a neck from a maple board. The craftsman uses a special calculator to calculate the neck size. You can get acquainted with it here.
Then, according to calculations, he makes a markup on the board. Saws a rough workpiece with a hacksaw. Then he processes the neck with a router.
Step Five: Fingerboard
Next, the master makes a fingerboard. He marks and cuts the frets on it. Sticks the fretboard to the neck.
The fret template can be downloaded here.
Step six : neck of the bar
Then the master fixes the bar in a vice with the back side up and processes it in the neck area. The corners of the head and neck should be rounded as in the photo.
Step Seven: holes for tuning pegs and installing frets
Drills holes for tuning pegs according to the template. The master makes a banjo with five strings. On the banjo, the fifth string is attached to a peg mounted on the neck of the neck.
Then he glues the sections between the cuts with masking tape and hammers the frets with a hammer. The protruding edges of the frets are bitten with wire cutters and filed at an angle of 45 degrees.
Step eight : Setting the neck
The neck should be set at a slight angle. To maintain the angle, the master cut a wedge and glued it to the neck.
To prevent the neck from moving during gluing, he cut off sharp nails from a pushpin and stuck them into the wood.
Step nine: the last details
Now you need to grind the place where the neck is glued to the body. Then he sets the nut and tightens the strings.
Everything is ready, you just need to adjust the instrument and you can play your favorite melody.
