My name is Nate Banton, I make Scottish smallpipes here in the US. I've long admired Mike's website on Northumbrian pipes and have used some tips from it over the years, but have never had a chance to use any of the drawings, until now.
I'm looking to redesign my low D drone. Over the years my drone reed designs have gotten more and more vibrant, and now my D drone, in particular, is just bit too loud. I thought looking at some Northumbrian pipe drones would make sense to get a little quieter drone design.
I don't know if it's my computer, or what, but I don't see any dimensions on Mike's drone drawings. The chanter drawings have dimensions, but not the drones.
I'm just looking for bore sizes and lengths, and hope you can help.
Cheers!
Nate Banton
PS, perhaps I should start a new topic on this, but I'd love to talk about how drone design and reed design allows for the ability of a drone to play more than one note...
