Homemade Banjo Ukulele (Banjolele) Hack

Homemade Banjo Ukulele (Banjolele)A little over a month ago, I posted a hack on how to make a cigar box guitar and tape recorder amplifier, that hopefully got you all in the musical spirit. If not, then today's hack will definitely get your feet a-stompin' and toes a-tappin'! Today we're going to learn how to make our very own homemade banjoleles.

Balno has posted an excellent tutorial on the Instructables site, on how to make a fully functional banjo ukulele from a few odds and ends. Balno's ingenius design includes a tambourine body with a ukulele neck mounted to it. The final results are pretty sweet! How can you make your own homemade banjolele? Well, according to Balno's instructable:

step 1: materials
- a ukulele neck and fretboard taken from a cheap soprano ukulele kit ($20 here in France). I bought mine here : http://www.thomann.de/fr/hosco_ukulele_kit.htm. Kit includes pegs and nuts. fine
- 8" tambourine (should cost about $15)
- a block of hard wood (1"1/2 x 2" approximately). I used sapelli, any harwood is fine.
- threaded rod (1/4", 2 ft.)
- aluminium tube (your threaded rod should fit in)
- 1/4" nuts + washers
- a metal piece with holes to make tailpiece. I used a piece of an old construction game called "Mecano".
- 2" of hard wood cleat (1/4" thick)
- plastic guitar saddle

step 2: making the neck longer
To play in tune, the most important thing is that the 12th fret must be placed exactly at the middle of the string length. If you attach the ukulele neck directly to the 8" tambourine, it won't work, you'll have to put the banjo bridge too near from the tambourine border in order to get a proper intonation.

THE SOLUTION : making the neck longer.

I used a block of hard wood and shaped in to fit the neck heel one side and the tambourine the other side. I used a dremel, various fillers ans sandpaper.

When doing this, you should have in mind that the neck is slightly tilted back on a ukulele, this helps getting appropriate action and intonation. Measure this on the kit you use and try to shape the wood block in consequence.

This piece of wood makes the neck 1" longer. It could be more, since the more the bridge is centered, the best the ukulele sounds.

Advice : you must take care of the wood grain. It's always better to have the grain of the block perpendicular to the tambourine. the piece of sapelli I found was too short to do this.
Since the neck is attached with a nut, the problem is cosmetic, but if you can get a piece of wood allowing this, it will look better and will be more durable.

This is how the neck is attached to the tambourine.

I drilled the heel and the hardwood and put two gudgeons to prevent the neck from rotating around the threaded rod.

The aluminium tube is cut to the exact internal size of the tambourine. Use washers everywhere it's possible (better look and finish and preventing loose fixation). Finish by nuts on the threaded rod.

step 4: Glueing the fretboard
See the kit's instructions on how to glue the fretboard.

This is how I did.

Finish the neck with sandpaper to get a smooth feeling.

step 5: Making the bridge
I cut the bridge in a piece of hardwood cleat.

The guitar saddle is cut to length and its side glued on the bridge.

On this peculiar prototype, the bridge is about 1/2" or less. Best height is obtained by trial.
I've tried several possibilities and it appeared that 3 legs bridges work best... At your convenience...

You can find 4 strings banjo bridges on the net, also.

Make slots to hold the strings using a fine filler. Be very careful at this point. Slots should fit the strings exactly for a better sound.

step 6: Making the tailpiece...
... depends on what you are using to attach the strings.

Attach the strings with small knots.

step 7: finishing the neck
I used varnish but oil is good for finishing ukulele necks.

pegs are mounted in the headstock and nut is put at the end of the fretboard. Don't glue it, string tension is enough to hold it in place.

step 8: Finished !
Advice : apply as much tension as you can to the tambourine skin !!! Skin tension really improves projection.

Use an electronic tuner to place the bridge correctly (BTW bridge is not glued, strings tension holds it in place). Once done, use a fine pencil to mark the place of the bridge (for further use :)

I've mounted Worth CM strings instead of the awful black strings supplied with the kit.

And this is how the banjo uke sounds like :

Does anyone know the Foggy Mountain Breakdown? Happy playing everyone!! :-)

    Hello there, I'm Balno.

    So I have to correct just a point. The tambourine used is actually a 8" tambourine... We use centimeters in France instead of inches and I made a mistake while converting.

    A 10" tambourine would make the instrument looking strange, with fat body and thin neck.

    Anyway, I think it is worth trying a 10" tambourine. In this case, you don't have to get the neck longer.

    When I will be more comfortable with fretting job, I plan to make a neck myself and get a 6" tambourine... But that's another story...

    And last tip, if you want to play your banjolele through an amplifier, you only have to get one of those small Radio Shack piezo transducers, put it under the bridge and plug... Wahoo, it blows your head off :)

    Thanks for mentionning this project and YOU keep on the good work :)

    Hello François,

    thanks for dropping by. I have gone ahead and changed it to 8 inches above. I too get confused sometimes with the conversions...we use centimeters here in Canada, as well. Anyways, thanks for your comments and tips and thanks for the awesome banjolele hack! :-)

    Greta write up. Where did you find a tambourine without the jingles? In the states, all I can find are ones with jingles.

    Thanks
