Trimming a clarinet

I'm fascinated by the construction of instruments. I tend to think of instruments as expensive and permanent, with acoustics fixed in form and unchangable. They're not of course. Someone made them. And to the maker, adjusting an instrument is no scarier than making it out of wood in the first place. Here's Morrie Backun tweaking a clarinet for Ricardo Morales, jamming a reamer into a $8k piece of wood as casually as any reedmaker, making reeds.
