Paul and I built a drum out of some old pine. We used Charlie Catlett’s table saw and cut 17 staves, each with angle 10.56 degrees off the vertical (geometry to the rescue). We glued, planed, sanded, stained, and then put two coats of tung oil on the shell. We bent the two metal rings (1/4″ round from home depot) and a local car repair shop welded them for free. The rope came from REI, and we soaked the sheepskin head for several hours before stretching it across the top.
