Nichols Wooden Banjo- February, 2010

Nichols Mostly Wooden Banjo-2010

Maple For Pot

This banjo started out as a piece of maple pictured here.

Sample piece for hexagonal shell

Here is the piece that I copied to make both halves of this pot. I made at least 12 of these splined pieces and a couple of extra ones. Also (although not shown in these pictures) there was a third piece made similarly that serves as a base for the little brass tone ring.

Grooves cut for splines

These grooves are cut for some plywood splines. The splines add extra strength.

Band clamp with plywood splines

Here is one of the blanks being glued.

Blanks ready to turn

Here are the 2 halves of this shell. One is the main shell and the other acts as a wooden tension hoop.

Lathe

Here is the shell mounted on my lathe.

rounded out

Here is the back half rounded out.

Ledge to fit other half of shell

Here is the piece with the ledge turned to fit the other half of the shell.

This part acts as the tension hoop

Here is the top part or tension hoop side of the shell.

Two halves fit together

Here are the 2 halves fit together.

Shell with head

These round edges make me happy.

Wooden part of tone ring

Shown here is the third piece of this shell. It floats in between the other 2 pieces and holds the small brass (Stew Mac) light weight 11 inch tone ring.

Here is that 3rd piece with the tone ring installed.

Test fitting the assembly

Here are the 3 pieces put together temporarily and tested with some little wedges to provide the tension for the head. I know this probably looks confusing.

2 Halves bolted togetheer to form pot

The main shell and the tension hoop part are attached to each other with these screws. The floating piece that has the tone ring on it is sandwiched between these two pieces.

Back half of shell

Here is the back or main shell after the 1/4 by 20 bolts and nuts were put into it. These bolts bear on the floating tone ring assembly and provide head tension.

Front half of shell

Here is the tension hoop part.

Detail of head tensioning bolts

This shows the head tensioning bolts. They are tightened after the two halves of the pot are together. A 7/16 inch open end wrench is all it takes to tension the head.

Pot with head installed

Here is the pot after staining and finishing. It has a different look doesn’t it? Smooth and clean looking.

Back of pot after assembly

 

Here is the back of the pot assembly. There are also some screws that go in from the sides to strengthen this assembly.

Bolted to neck

Here is the pot bolted to the neck. This neck started life as a Japanese bowtie copy banjo neck. It has now been recycled into a neck to fit this banjo. I removed the frets and radius-ed the fingerboard.

Modified neck

Here is the finished banjo.

Pot

The finished pot. It can be played as an open back.

With quick-mount resonator

It can also be played with a resonator.

Modified resonator with quick- mount feature

I modified the resonator that went with that neck and made it so it can be attached and removed with just a tug. The resonator was modified a lot to allow this.

Back of resonator

Here is the back of this resonator.

Here is another shot of this pot showing part of the neck.

Front

The completed product.

Pot depth is only around 3 inches

The depth of this pot is only about 3 inches. It weighs about half of what a Gibson type banjo weighs. The fingerboard is raised above the plane of the head to allow for picking without picks touching the head. It has the Nichols ultra rounded edges on it.

Back of pot

Here is the back side of the pot.

Nichol Bridge- Note radius (approximately 6 inch radius)

Naturally it has a Nichols Bridge on it. It is a radius-ed maple bridge.

Radiused fingerboard- 6" radius

It also has a radius-ed fingerboard. I’m sure this isn’t for everyone. It has some features on it that I like. It has a pleasant tone and the pot not being so thick is a good feeling for me. It is part of an ongoing experiment for me.
