I considered a drill press, but I do not like the fact that with a drill press I need to move the table with the work piece up or down when changing to different size drill bits. I like the drill table and work piece at a constant height, bolted down to my work table, so I can do the job sitting down and have the same view and arm angles. Perhaps a bit primitive, but it suits me (apart from the fact that a power drill is noisier than a drill press).
You could make a jig with 2 sliding triangles to support the whistle. Slide them together raises the whistle, sliding them apart lowers it; then you can leave the table alone.
