Here are a few photos of a new wood I can now offer.  It is tempered birdseye
maple from a supplier in Arizona.  Tempering is a process of heating the wood in
a low-oxygen environment.  The result is more stable, darkened in colour and
more water-proof than the original wood.  These photos do not do the grain
justice.  It seems to move, depending on the direction of the light.  
Here is a series of photos showing the
making of a pair of purpleheart Rovers.
The Whisolo is a keyed pennywhistle. It is made from a
standard piccolo body and the same mouthpiece I use on my
narrow-bore brass whistles.  Click
here to see photos and
hear samples.  
Here is a Youtube video where you can see it
put through its paces.
New Case Design for multi-body sets-
