Instrument Building (aka Luthiery)

Here's some information about musical instruments I have built.

Bodhran (Celtic Drum)

My first bodhran was an exercise in laminating wood into a curved shape in preparation for building a harp.  My first bodhran was a cross-braced rim with a skin tacked on.  In the humid Queensland climate, however, this proved to be inconvenient, as the skin alternates between to tight and too slack.  My second bodhran was a double rim tuneable version, allowing skin tension adjustment to suit the weather.  I also left out the cross braces on the second bodhran, and made it a bit smaller - I find the smaller size more comfortable to play.

The bits inside the smaller drum are the tippers (sticks).  The stick with balls on each end was home made (I don't have a lathe).  The other one was a bought one.  I like the natural mottled look of these goat skins.  They have been oiled, and it's really brought out the colouring of the skins.

Celtic Folk Harp

The Celtic folk harp is certainly my biggest woodworking achievement.   This started my interest in instrument building, after promising to make a harp for my sister.  So far (start 2004), I have built eight harps to this 30 string celtic design.  Soon I'll be starting on a 36 string classical harp design.  If anyone wants to buy one, you can email me for details.

The harps are made from Brazilian mahogany neck and pedestal, sapele rounded back, and King William pine sound board.  I have used nylon strings and fitted Robinson's sharping levers (not pictured).

Tin Whistles

(no picture yet)

Tin whistles are a nice simple instrument, and easy to build.  There are plenty of plans on the web.  I made my own dimensions for different keys by scaling up my high D tin whistle, and then adjusting by experimentation.

Conga Drum

If you ever want to build a conga drum, don't bother.  Just buy one.   Building it will cost you more than buying one.  Of course, I knew that before I started, but I just had to see for myself.  Anyway, it makes a nice lounge room ornament.  It sounds OK too, but it wasn't worth the effort.

For those who care, the body is made from Meranti (Pacific Maple).  The staves were hand shaped, steam bent and glued together, nailed onto a mould.  The mould was built to be removable from inside the completed drum.  After the mould was taken out, the inside of the drum was fibreglassed for strength.  The outside was planed and sanded smooth and varnished.  The rim is a traditional double rim held down by eye bolts.

Future Plans

After building this next harp, I'm planning to build a guitar.   I'm looking at a dreadnought size steel string, Qld maple back, sides and neck, Sitka spruce front, and rosewood fingerboard.  Plans are going to come from a book called "A Guitar Maker's Manual" by Jim Williams.  Plans to build a violin have been shelved for the moment, in lieu of other projects.
