I have been playing my C gaita recently and I decided to make a small drone to go with it. I did not want to make the large C drone that normal go with a C gaita, but something I can carry around and make drone while I practice. I drilled though a piece of Bubinga wood and made 2 half from the one piece, 50cm each length. internal bore was 6mm. then I began designing the top sliding part. the internal diameter was 12mm. and I played around with the design.
The bottom standing part has an outside diameter of 12mm. the overall outside diameter of both pieces was 15mm.
The design for the bottom standing part was an idea I have been had for sometime and I wanted to try it out. if it did not work it could always be used for a chair leg!!
When I make the reed I will cover it in a removable stock and this will be inserted into a drone stock in the bag. It plays in C and I will make different sections for the top/movable part so I can play in D and Bb. I was gonna drill holes further up the drone but I decided to make new sections. This will add to the tembre of the sound.
I also intend to make a middle section to this C drone until I have a bass C playing alongside this tenor C. with 2 drones going it will be nicer for the gaita chanter which can be quite shrill. I have been thinning down the reed and now it plays a lot quieter than normal, this is for use indoors (pub setting).
