The boobams are currently in storage, but I'll try to snap some pics this weekend. They are surprisingly straightforward to construct, provided you follow the math. I've got a history of building organ pipes, and the same concept applies to boobams as applies to a stopped flue pipe, like a bourdon. Calculate the quarter-wavelegnth of a given pitch, and cut your tube a hair longer to account for error and tuneability.

I decided to go old school with my heads and sourced some "all natural boars hide" dog chews produced in Australia of all places. Surprisingly cheap compared to buying "instrument grade" hide, and just wide enough when soaked and unrolled to cover the end of a 4" pvc pipe. Upholstery tacks to hold it in place, let it dry, and you have a boobam!
