A very green piece of wood is hollowed out and a narrow channel is carved in it. A fitted wooden round is then slid into place and the whole item is allowed to dry. As the wood dries, it shrinks, locking the bottom into the carved channel. Once cured, it is as solid as a single piece.
To get certified for this BB provide photos or video (less than 2 minutes) showing the following:
- Your chunks of wood that you are starting with
- The hollowed section and carved bottom unconnected, with the hand tools you have decided to use for this
- The finished product in use
Now I am super curious what sports would be like if we allowed drugs and tiny ads.
