I've been playing the last few days. I took bits of a maple I had to take down and let dry for a while and made this. It is close to 175 mm tall and has a diameter of about 110 mm at the top. The straps are pallet strapping and, like in traditional coopering, hold the whole thing together. I does have a bottom but is not exactly water tight. It dribbles a bit from the bottom and has 1 small leak between 2 staves. I haven't yet put any finish on it.
So what to y'all think?
