Gee. I should have taken notes. The cylinder was 12" long, and the comb had about 110 teeth, with up to 6 teeth per note for trills. The music was classical, and arranged by Hind.
He built everything, even to cutting his own gears (and the worm). He showed his calculations in the talk. I think we can expect a full description in an upcoming MBSI Journal.
Regarding Sherline tools: There is now a long bed Sherline which can take a set of blocks to raise the chuck and tailstock over the ways. This is large enough for the average cylinder to be spun. Hind showed his setup for drilling, which was a rotary dividing table clamped to the headstock wheel to set the angular position, and a drill in a flexible shaft tool clamped to the back of the cross slide, which could be moved in to drill a hole. The cross slide was attached to a dial caliper, which gave him linear position (and which is why he chose 0.1" as the tooth pitch). He made up a table of hole positions (by hand), and drilled from the table.
If there was any particular feature of Hind's presentation, it was that he has a lot of patience. It took him 2 years to make the movement.
By the way, he makes his living by making ocarinas and selling them through music stores and at street fairs.
